&lt;hr /&gt;
&lt;div&gt;=Appellate Brief by Aerotel (on Behalf of LG Electronics)=&lt;br /&gt;
&lt;br /&gt;
In the CAFC, it was ruled that the LGE patents were not exhausted by the sale of the Intel made products under these patents to Quanta Computer.  Therefore, LG had the right to limit the way in which the components were used by Quanta, including prohibiting them from combining the Intel made components with other non-Intel components.  &lt;br /&gt;
&lt;br /&gt;
In this brief, Aerotel argues that the holder of a patent can exercise rights over a patented product in the hands of a downstream user under certain conditions.  The patent is exhausted only if the maker sells the product unconditionally.  In this case however, LG imposed restrictions on the way in which Intel could sell the products, preventing exhaustion.&lt;br /&gt;
&lt;br /&gt;
Aerotel also argues that the theory of exhaustion requires that the holder of the patent has received the full value of the goods in the sale.  In this case, there is no way that LG could bargain for and receive the full value for the licenced goods because it is impossible to predict the value of the products as they are sold further downstream.  They only way in which LG could receive the full value for its patents is to separately licence Intel&#039;s customers to use the products.   It would be impossible to obtain the full value of the patent from the Intel licence agreement only, because the full value is unknown until the product reaches the downstream market.  &lt;br /&gt;
&lt;br /&gt;
Exhaustion should not apply, therefore, in the case in which the patentee forgoes monetary compensation for his patent, and instead reserves the rights over the patented products against downstream users.&lt;br /&gt;

&lt;div&gt;=Brief on Behalf of Honeywell=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In the CAFC, Honeywell lost because it was ruled that the additional element which Hamilton Sunstrand added to their patented invention was foreseeable at the time that the patent was issued.   Hamilton Sunstrand used an inlet guide valve (IGV) in a system to control the air which is bled off in a turbine engine, in order to solve the ‘double solution’ problem which was common in such a system.  Honeywell’s case that Sunstrand infringed upon their patent relies upon the Doctrine of Equivalence, which can be used to rule infringement when a patent has not been literally infringed.  Sunstrand argued that this additional use of the IGV prevents their system from being equivalent to what is claimed in the Honeywell patent.  They claimed that the addition they made to the Honeywell system was ‘foreseeable,’ which under Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Corp. prevents it from being protected under the claims of the Honeywell patent.  This case says that equivalents are protected under the claims of a patent unless the equivalent was foreseeable at the time of the invention.  &lt;br /&gt;
&lt;br /&gt;
Sunstrand claims that its invention was foreseeable, therefore not protected.  &lt;br /&gt;
The addition Sunstrand made was made roughly ten years after the Honeywell patent was filed, which itself suggests that there addition was not foreseeable.  Testimony showed that the double solution problem was a known issue well before the time Sunstrand added the IGV to their system, and thus it is reasonable to believe that if such a solution to the problem were foreseeable ten years earlier, it would have been used at that time.  Further, Sunstrand claims that their invention was both ‘unique’ and ‘foreseeable.’  This also seems to be a contradiction.  If it were foreseeable, presumable it would be common in the field.  Therefore, the additional element which Sunstrand added was not foreseeable at the time of the Honeywell patent, and thus their system infringes upon Honeywell’s patent.&lt;br /&gt;

&lt;div&gt;=Bruckelmyer v. Ground Heaters, Inc. (concerning Prior Publication)= &lt;br /&gt;
In this case, Bruckelmyer v. Ground Heaters, Inc (445 F.3d 1374), the U.S. Court of Appeals for the Federal Circuit ruled that a canceled patent application constituted a prior publication as far as section 102 is concerned.  In this case Bruckelmyer patented a process of warming frozen ground in order to allow concrete to be poured by using heated liquid in hoses placed along the concrete form.  A Canadian patent issued 13 years earlier discribed a similar method of heating structures by pumping preheated liquid through flexible hoses.  In the application for the Canadian patent, one of the typical uses was listed as &#039;thawing frozen ground&#039; in order to pour concrete.  The patent application also included two figures disclosing the setup of such a system.  These figures were removed in the issued patent, but the figures remained in the patent&#039;s file wrapper.  The court ruled that they these figures constituted a prior publication even though they were not themselves indexed, becuase they were part of the file wrapper of a patent which was indexed, and thus could have been found by a person familiar with the field.&lt;br /&gt;

		<summary type="html">&lt;p&gt;John Gallagher: /* Historical Development */&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The origin of the standard of non-obviousness is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in [[Hotchkiss v. Greenwood]], began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.&lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
In the law, Congress also claims that they did not wish to set a new standard for inventiveness.  They intended that all of the earlier standards and measures should apply.  However, they introduced the language of &#039;obviousness,&#039; which necessarily becomes the new standard, and is not quite the same as the standards used in previous court cases. From this point forward, an invention must be non-obvious in order to qualify for a patent. &lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;
&lt;br /&gt;
===U.S. v. Adams (1966)===&lt;br /&gt;
&lt;br /&gt;
* 1966: [[US v. Adams, 383 U.S. 39 (1966)]] All the evidence must be considered.  Even small changes can have large consequences, which is relevant to a determination of nonobviousness.&lt;br /&gt;
&lt;br /&gt;
===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or known elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;
*This case also considers the concept of &#039;&#039;enablement&#039;&#039; which means that that patent specification must be complete enough so that someone with ordinary skill in the art would be able to make the invention.  Enablement is set out in 35 USC 112.&lt;br /&gt;
&lt;br /&gt;
==The Inventive Step==&lt;br /&gt;
&lt;br /&gt;
==Relationship with Novelty==&lt;br /&gt;
Novelty and Non-obviousness are separate requirements for patentability, and must be evaluated separately.  The novelty requirement, dealt with under section 102[http://www.law.cornell.edu/uscode/html/uscode35/usc_sec_35_00000102----000-.html], is meant to determine whether an article has already been invented, and has detailed rules used to make this determination.  Non-obviousness, on the other hand, is concerned with whether an article constitutes a significant enough advancement from the prior art to be considered an invention. In other words, novelty means that the &#039;&#039;exact&#039;&#039; invention does not already exist, whereas non-obviousness means that the invention is different enough from prior inventions.&lt;br /&gt;
&lt;br /&gt;
==Nonobviousness vs. Invention==&lt;br /&gt;
==Considerations in Determining Patentability==&lt;br /&gt;
After the change of patent law in the U.S. Code in 1952, the standard of an invention became whether it was non-obvious to a person having ordinary skill in the pertinent art.  In Graham v. John Deere, the court laid out a method for determining whether a claim met this standard of non-obviousness. &lt;br /&gt;
 &lt;br /&gt;
===Primary Considerations===&lt;br /&gt;
*First, the scope of the prior art is to be evaluated.  This involves examining prior patents, examining published writings and consulting experts in the field to determine what methods and are used in industry.  &lt;br /&gt;
*Second, the claims at issue are to be ascertained.  This simply requires that the claims in the patent should be examined and understood.  This is simple conceptually, but there may be difficult in determining exactly what claims are made and what there scope is.&lt;br /&gt;
*Thirdly, the level of ordinary skill in the art is to be determined.&lt;br /&gt;
Having decided these issues, obviousness or non-obviousness can be determined.&lt;br /&gt;
===Secondary Considerations===&lt;br /&gt;
Along with the primary considerations, there are several other considerations which may help indicate that an invention is non-obvious:&lt;br /&gt;
*&#039;&#039;&#039;A long felt unmet need for the invention:&#039;&#039;&#039; If people have been looking for the solution to a problem, and have for a long time been unable to find one, it suggests that the invention which provides a solution was not obvious.  If it were, someone would already have invented it.&lt;br /&gt;
*&#039;&#039;&#039;Commercial success&#039;&#039;&#039; Commercial success may indicate non-obviousness; the fact that one person was able to create a much-desired product which other people were unable to suggests that his product or in method was not obvious to those other people.&lt;br /&gt;
*&#039;&#039;&#039;Teaching, Suggesting, or Motivation (TSM) Test&#039;&#039;&#039;&lt;br /&gt;
The courts have deviated from this pattern, sometimes placing more emphasis on what Graham v. John Deere claims should be secondary. However, recently, in 2007, the supreme court reaffirmed the pattern laid out in Graham v. John Deere in [[KSR International Co. v. Teleflex, Inc., 550 U.S. 398 (2007)]], insisting that the secondary considerations not be weighed more that the determination of the ordinary skill in the art.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.  The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in [[Hotchkiss v. Greenwood]], began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
In the law, Congress also claims that they did not wish to set a new standard for inventiveness.  They intended that all of the earlier standards and measures should apply.  However, they introduced the language of &#039;obviousness,&#039; which necessarily becomes the new standard, and is not quite the same as the standards used in previous court cases. From this point forward, an invention must be non-obvious in order to qualify for a patent. &lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;
&lt;br /&gt;
===U.S. v. Adams (1966)===&lt;br /&gt;
&lt;br /&gt;
* 1966: [[US v. Adams, 383 U.S. 39 (1966)]] All the evidence must be considered.  Even small changes can have large consequences, which is relevant to a determination of nonobviousness.&lt;br /&gt;
&lt;br /&gt;
===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or known elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;
*This case also considers the concept of &#039;&#039;enablement&#039;&#039; which means that that patent specification must be complete enough so that someone with ordinary skill in the art would be able to make the invention.  Enablement is set out in 35 USC 112.&lt;br /&gt;
&lt;br /&gt;
==The Inventive Step==&lt;br /&gt;
&lt;br /&gt;
==Relationship with Novelty==&lt;br /&gt;
Novelty and Non-obviousness are separate requirements for patentability, and must be evaluated separately.  The novelty requirement, dealt with under section 102[http://www.law.cornell.edu/uscode/html/uscode35/usc_sec_35_00000102----000-.html], is meant to determine whether an article has already been invented, and has detailed rules used to make this determination.  Non-obviousness, on the other hand, is concerned with whether an article constitutes a significant enough advancement from the prior art to be considered an invention. In other words, novelty means that the &#039;&#039;exact&#039;&#039; invention does not already exist, whereas non-obviousness means that the invention is different enough from prior inventions.&lt;br /&gt;
&lt;br /&gt;
==Nonobviousness vs. Invention==&lt;br /&gt;
==Considerations in Determining Patentability==&lt;br /&gt;
After the change of patent law in the U.S. Code in 1952, the standard of an invention became whether it was non-obvious to a person having ordinary skill in the pertinent art.  In Graham v. John Deere, the court laid out a method for determining whether a claim met this standard of non-obviousness. &lt;br /&gt;
 &lt;br /&gt;
===Primary Considerations===&lt;br /&gt;
*First, the scope of the prior art is to be evaluated.  This involves examining prior patents, examining published writings and consulting experts in the field to determine what methods and are used in industry.  &lt;br /&gt;
*Second, the claims at issue are to be ascertained.  This simply requires that the claims in the patent should be examined and understood.  This is simple conceptually, but there may be difficult in determining exactly what claims are made and what there scope is.&lt;br /&gt;
*Thirdly, the level of ordinary skill in the art is to be determined.&lt;br /&gt;
Having decided these issues, obviousness or non-obviousness can be determined.&lt;br /&gt;
===Secondary Considerations===&lt;br /&gt;
Along with the primary considerations, there are several other considerations which may help indicate that an invention is non-obvious:&lt;br /&gt;
*&#039;&#039;&#039;A long felt unmet need for the invention:&#039;&#039;&#039; If people have been looking for the solution to a problem, and have for a long time been unable to find one, it suggests that the invention which provides a solution was not obvious.  If it were, someone would already have invented it.&lt;br /&gt;
*&#039;&#039;&#039;Commercial success&#039;&#039;&#039; Commercial success may indicate non-obviousness; the fact that one person was able to create a much-desired product which other people were unable to suggests that his product or in method was not obvious to those other people.&lt;br /&gt;
*&#039;&#039;&#039;Teaching, Suggesting, or Motivation (TSM) Test&#039;&#039;&#039;&lt;br /&gt;
The courts have deviated from this pattern, sometimes placing more emphasis on what Graham v. John Deere claims should be secondary. However, recently, in 2007, the supreme court reaffirmed the pattern laid out in Graham v. John Deere in [[KSR International Co. v. Teleflex, Inc., 550 U.S. 398 (2007)]], insisting that the secondary considerations not be weighed more that the determination of the ordinary skill in the art.&lt;br /&gt;

The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.

This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
In the law, Congress also claims that they did not wish to set a new standard for inventiveness.  They intended that all of the earlier standards and measures should apply.  However, they introduced the language of &#039;obviousness,&#039; which necessarily becomes the new standard, and is not quite the same as the standards used in previous court cases. From this point forward, an invention must be non-obvious in order to qualify for a patent. &lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;
&lt;br /&gt;
===U.S. v. Adams (1966)===&lt;br /&gt;
&lt;br /&gt;
* 1966: [[US v. Adams, 383 U.S. 39 (1966)]] All the evidence must be considered.  Even small changes can have large consequences, which is relevant to a determination of nonobviousness.&lt;br /&gt;
&lt;br /&gt;
===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or known elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;
*This case also considers the concept of &#039;&#039;enablement&#039;&#039; which means that that patent specification must be complete enough so that someone with ordinary skill in the art would be able to make the invention.  Enablement is set out in 35 USC 112.&lt;br /&gt;
&lt;br /&gt;
==The Inventive Step==&lt;br /&gt;
&lt;br /&gt;
==Relationship with Novelty==&lt;br /&gt;
Novelty and Non-obviousness are separate requirements for patentability, and must be evaluated separately.  The novelty requirement, dealt with under section 102[http://www.law.cornell.edu/uscode/html/uscode35/usc_sec_35_00000102----000-.html], is meant to determine whether an article has already been invented, and has detailed rules used to make this determination.  Non-obviousness, on the other hand, is concerned with whether an article constitutes a significant enough advancement from the prior art to be considered an invention. In other words, novelty means that the &#039;&#039;exact&#039;&#039; invention does not already exist, whereas non-obviousness means that the invention is different enough from prior inventions.&lt;br /&gt;
&lt;br /&gt;
==Nonobviousness vs. Invention==&lt;br /&gt;
==Considerations in Determining Patentability==&lt;br /&gt;
After the change of patent law in the U.S. Code in 1952, the standard of an invention became whether it was non-obvious to a person having ordinary skill in the pertinent art.  In [[Graham v. John Deere]], the court laid out a method for determining whether a claim met this standard of non-obviousness. &lt;br /&gt;
 &lt;br /&gt;
===Primary Considerations===&lt;br /&gt;
*First, the scope of the prior art is to be evaluated.  This involves examining prior patents, examining writings and consulting experts in the field, to determine what methods and are used in industry.  &lt;br /&gt;
*Second, the claims at issue are to be ascertained.  This simply requires that the claims in the patent should be examined and understood.  This is simple conceptually, but there may be difficult in determining exactly what claims are made and what there scope is.&lt;br /&gt;
*Thirdly, the level of ordinary skill in the art is to be determined.  &lt;br /&gt;
===Secondary Considerations===&lt;br /&gt;
&lt;br /&gt;
The courts have deviated from this pattern, sometimes placing more emphasis on what [[Graham v. John Deere]] claims should be secondary. However, recently, in 2007, the supreme court reaffirmed the pattern laid out in [[Graham v. John Deere]] in [[KSR International Co. v. Teleflex, Inc., 550 U.S. 398 (2007)]], insisting that the secondary considerations not be weighed more that the determination of the ordinary skill in the art.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.  The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in [[Hotchkiss v. Greenwood]], began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
In the law, Congress also claims that they did not wish to set a new standard for inventiveness.  They intended that all of the earlier standards and measures should apply.  However, they introduced the language of &#039;obviousness,&#039; which necessarily becomes the new standard, and is not quite the same as the standards used in previous court cases. From this point forward, an invention must be non-obvious in order to qualify for a patent. &lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;

*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;

&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
In the law, Congress also claims that they did not wish to set a new standard for inventiveness.  They intended that all of the earlier standards and measures should apply.  However, they introduced the language of &#039;obviousness,&#039; which necessarily becomes the new standard, and is not quite the same as the standards used in previous court cases. From this point forward, an invention must be non-obvious in order to qualify for a patent. &lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;
&lt;br /&gt;
===U.S. v. Adams (1966)===&lt;br /&gt;
&lt;br /&gt;
* 1966: [[US v. Adams, 383 U.S. 39 (1966)]] All the evidence must be considered.  Even small changes can have large consequences, which is relevant to a determination of nonobviousness.&lt;br /&gt;
&lt;br /&gt;
===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or know elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;
*This case also considers the concept of &#039;&#039;enablement&#039;&#039; which means that that patent specification must be complete enough so that someone with ordinary skill in the art would be able to make the invention.  Enablement is set out in 35 USC 112.&lt;br /&gt;
&lt;br /&gt;
==The Inventive Step==&lt;br /&gt;
&lt;br /&gt;
==Relationship with Novelty==&lt;br /&gt;
Novelty and Non-obviousness are separate requirements for patentability, and must be evaluated separately.  The novelty requirement, dealt with under section 102[http://www.law.cornell.edu/uscode/html/uscode35/usc_sec_35_00000102----000-.html], is meant to determine whether an article has already been invented, and has detailed rules used to make this determination.  Non-obviousness, on the other hand, is concerned with whether an article constitutes a significant enough advancement from the prior art to be considered an invention. In other words, novelty means that the &#039;&#039;exact&#039;&#039; invention does not already exist, whereas non-obviousness means that the invention is different enough from prior inventions.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.  The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in [[Hotchkiss v. Greenwood]], began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;

We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;

===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;

===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or know elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;
*The secondary considerations, commercial success, are not optional considerations.  If evidence is available pertaining to them, they &#039;&#039;must&#039;&#039; be considered by the court.&lt;br /&gt;
*This case also considers the concept of &#039;&#039;enablement&#039;&#039; which means that that patent specification must be complete enough so that someone with ordinary skill in the art would be able to make the invention.  Enablement is set out in 35 USC 112.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.  The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in [[Hotchkiss v. Greenwood]], began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  In this 1850 case, the U.S. Supreme Court deemed a patent on a clay doornob invalid, because it did not qualify as an invention. This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.  The court ruled that &lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
Here the Supreme Court concedes that using superior materials to create a better or cheaper doornob was an improvement, and that it may well have taken skill and knowledge.  However, they decided it did not qualify as an invention because it lacked the ingenuity that the word implies.  Farther in its opinion, the court claims that &lt;br /&gt;
&lt;br /&gt;
:unless more ingenuity and skill...were required...than were possessed by an ordinary mechanic acquainted with the business, there was an absence of that degree of skill and ingenuity which constitute essential elements of every invention. In other words, the improvement is the work  of the skillful mechanic, not that of the inventor.&lt;br /&gt;
&lt;br /&gt;
This then becomes the standard for measuring inventiveness: if the article in question could have been produced by an ordinary artisan or mechanic whose skill lay in that field, then the article could not be an invention.  This remains the standard until the change in 1952 of the section of U.S. Code dealing with patent law.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field.

Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v.

&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard in patent law.  The origin of this standard is found in the Constitution, which give Congress to grant &#039;exclusive rights&#039; i.e. a patent, to a person for his invention.  A question soon arose about what counted as an invention, and whether it could be a trivial improvement, or whether it had to be fairly substantial.  The courts, beginning mainly with the decision in Hotchkiss v. Greenwood, began to develop a testable standard for patentability, which claimed that an innovation was not an invention if it could have been developed by an ordinary mechanic skilled in the particular field.  Congress attempted to codify this standard in 1952, and they introduced the idea that a development must be &#039;non-obvious&#039; in order to qualify for a patent.  This has remained the law since, but there has been much work done by the court in order to determine what qualifies as obvious. &lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention.&lt;br /&gt;
*First the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;
===Lyon v. Bausch &amp;amp; Lomb (1955)===&lt;br /&gt;
&lt;br /&gt;
In [[Lyon v. Bausch &amp;amp; Lomb, 224 F.2d 530 (1955)]] Learned Hand, in his brilliance, expounded on the new standard thusly:&lt;br /&gt;
:Therefore we at length come to the question whether Lyon&#039;s contribution, his added step, was enough to support a patent. It certainly would have done so twenty or thirty years ago; indeed it conforms to the accepted standards of that time. The most competent workers in the field had for at least ten years been seeking a hardy, tenacious coating to prevent reflection; there had been a number of attempts, none satisfactory; meanwhile nothing in the implementary arts had been lacking to put the advance into operation; when it appeared, it supplanted the existing practice and occupied substantially the whole field. We do not see how any combination of evidence could more completely demonstrate that, simple as it was, the change had not been &amp;quot;obvious * * * to a person having ordinary skill in the art&amp;quot; — § 103. On the other hand it must be owned that, had the case come up for decision within twenty, or perhaps, twenty-five, years before the Act of 1952 went into effect on January 1, 1953, it is almost certain that the claims would have been held invalid. The Courts of Appeal have very generally found in the recent opinions of the Supreme Court a disposition to insist upon a stricter test of invention than it used to apply — indefinite it is true, but indubitably stricter than that defined in § 103.4&lt;br /&gt;
&lt;br /&gt;
===Graham v. John Deere (1966)===&lt;br /&gt;
&lt;br /&gt;
In [[Graham v. John Deere, 383 U.S. 1 (1966)]] indicated a shift away from trying to establish a level of &amp;quot;inventiveness&amp;quot; to the statutory language of &amp;quot;nonobviousness.&amp;quot;  The criteria to determine nonobviousness include&lt;br /&gt;
* scope and content of the prior art;&lt;br /&gt;
* differences between the prior art and the claims at issue;&lt;br /&gt;
* level of ordinary skill in the pertinent art; and,&lt;br /&gt;
* secondary considerations, including:&lt;br /&gt;
** commercial success of the invention;&lt;br /&gt;
** long-felt but unsolved needs;&lt;br /&gt;
** failure of others to find a solution, etc.&lt;br /&gt;
&lt;br /&gt;
===U.S. v. Adams (1966)===&lt;br /&gt;
&lt;br /&gt;
* 1966: [[US v. Adams, 383 U.S. 39 (1966)]] All the evidence must be considered.  Even small changes can have large consequences, which is relevant to a determination of nonobviousness.&lt;br /&gt;
&lt;br /&gt;
===Anderson&#039;s Black Rock v. Pavement Salvage (1969)===&lt;br /&gt;
Things seem relatively clear at this point, but the Supreme Court seemingly basically messed it all up again in [[Anderson&#039;s Black Rock, Inc. v. Pavement Co., 396 U.S. 57 (1969)]] by returning the focus to &amp;quot;inventiveness&amp;quot; by revisiting the old problem of when a combination of old or know elements can become patentable.&lt;br /&gt;
&lt;br /&gt;
==Suggestion to Combine==&lt;br /&gt;
[[In Re Rouffet]] deals with the issue of a combination of previously-patented elements.  The cases above all pre-dated the 1952 statute and the 1966 Supreme Court cases.&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;When a rejection depends on a combination of prior art references, there must be some teaching, suggestion, or motivation to combine the references.&amp;quot;&lt;br /&gt;
:&amp;quot;[T]he suggestion to combine requirement is a safeguard against the use of hindsight combinations to negate patentability. While the skill level is a component of the inquiry for a suggestion to combine, a lofty level of skill alone does not suffice to supply a motivation to combine. Otherwise a high level of ordinary skill in an art field would almost always preclude patentable inventions. As this court has often noted, invention itself is the process of combining prior art in a nonobvious manner.&lt;br /&gt;
&lt;br /&gt;
==Objective Tests==&lt;br /&gt;
Two important considerations were the focus of [[Hybritech v. Monoclonal Antiboties, 802 F.2d 1375]].&lt;br /&gt;
*A lot of the evidences hinges on laboratory notebooks.  The CAFC held that even though the lab notebooks were not witnessed until months or about a year after did not preclude them of being of credible evidentiary value.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==Historical Development==&lt;br /&gt;
The following are some cases through history that trace the evolution of what is currently the nonobviousness standard.&lt;br /&gt;
&lt;br /&gt;
===Hotchkiss v. Greenwood (1850)===&lt;br /&gt;
&lt;br /&gt;
Prior to [[Hotchkiss v. Greenwood]] an invention only had to be novel.  This case basically established the notion that there had to me more to it, some sort of threshold for inventivness, which ultimately became the idea of &#039;&#039;nonobviousness&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
:...the novelty consisted in the substitution of the clay knob in the place of one made of metal or wood, as the case might be. And in order to appreciate still more clearly the extent of the novelty claimed, it is proper to add, that this knob of potter&#039;s clay is not new, and therefore constitutes no part of the discovery. If it was, a very different question would arise, as it might very well be urged, and successfully urged, that a knob of a new composition of matter, to which this old contrivance had been applied, and which resulted in a new and useful article, was the proper subject of a patent.&lt;br /&gt;
&lt;br /&gt;
:The novelty would consist in the new composition made practically useful for the purposes of life, by the means and contrivances mentioned. It would be a new manufacture, and nonetheless so, within the meaning of the patent law, because the means employed to adapt the new composition to a useful purpose was old, or well known.&lt;br /&gt;
&lt;br /&gt;
:But in the case before us, the knob is not new, nor the metallic shank and spindle, nor the dovetail form of the cavity in the knob, nor the means by which the metallic shank is securely fastened therein. All these were well known, and in common use, and the only thing new is the substitution of a knob of a different material from that heretofore used in connection with this arrangement.&lt;br /&gt;
&lt;br /&gt;
:Now it may very well be, that, by connecting the clay or porcelain knob with the metallic shank in this well known mode, an article is produced better and cheaper than in the case of the metallic or wood knob; but this does not result from any new mechanical device or contrivance, but from the fact, that the material of which the knob is composed happens to be better adapted to the purpose for which it is made. The improvement consists in the superiority of the material, and which is not new, over that previously employed in making the knob.&lt;br /&gt;
&lt;br /&gt;
:But this of itself can never be the subject of a patent. No one will pretend that a machine, made, in whole or in part, of materials better adapted to the purpose for which it is used than the materials of which the old one is constructed, and for that reason better and cheaper, can be distinguished from the old one, or, in the sense of the patent law, can entitle the manufacturer to a patent.&lt;br /&gt;
&lt;br /&gt;
:The difference is formal, and destitute of ingenuity or invention. It may afford evidence of judgment and skill in the selection and adaptation of the materials in the manufacture of the instrument for the purposes intended, but nothing more.&lt;br /&gt;
&lt;br /&gt;
It can be seen in this pronouncement of the court opinion by Justice Nelson, that the original requirement of novelty is not satisfactory, as the knob designed by Hotchkiss is a new product. Although the term &amp;quot;nonobviousness&amp;quot; will not be developed for some time, the court&#039;s decision hinges on the fact that the mere substitution of better suited materials is too obvious a development to warrant a patent. The fundamental premise of nonobviousness is presented a few paragraphs later, as Justice Nelson states,&lt;br /&gt;
&lt;br /&gt;
:&amp;quot;....unless more ingenuity and skill in applying the old method of fastening the shank and the knob were required in the application of it to the clay or porcelain knob than &#039;&#039;were possessed by an ordinary mechanic acquainted with the business&#039;&#039;, there was an absence of that degree of skill and ingeunity which constitute essential elements of every invention. In other words, the improvement is the work of the skillful mechanic, not that of the inventor.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Thus, it is made clear that an invention must not only be novel, but must require a level of ingenuity that exceeds that of an individual with ordinary skill in the related field.&lt;br /&gt;
&lt;br /&gt;
===A&amp;amp;P Tea v. Supermarket Equipment (1950)===&lt;br /&gt;
&lt;br /&gt;
While it pre-dates the language of section 103, [[A. &amp;amp; P. Tea Co. v. Supermarket Corp., 340 U.S. 147 (1950)]] discussed some of the more difficult issues related to the level of invention. In particular, this case dealt with three significant issues related to the process of determining patentability:&lt;br /&gt;
&lt;br /&gt;
*First, that the &amp;quot;level of invention&amp;quot; was partly evidenced by &amp;quot;long felt but unsatisfied need&amp;quot; which is a standard used today for nonobviousness.&lt;br /&gt;
&lt;br /&gt;
The importance of a &amp;quot;long felt but unsatisfied need&amp;quot; in the determination of nonobviousness is that it is difficult to claim that an invention is obvious if there has been a demand for a certain product and no one has been able to fulfill that need. However, it is important to note that there are two requirements that must be met here. There must be a need for the product and the need must have existed for a long time. If the need is relatively new, then it is difficult to claim that a person with ordinary skill in the field would have not developed such a design had he been aware of demand for such a device. On the other hand, if the market related to a certain field has provided no sign that there is a need for such an improvement, then it can be argued that the design would have been obvious had anyone expressed interest in the proposed device.&lt;br /&gt;
&lt;br /&gt;
*Second, it expressed a bias toward patent protection at the frontier of science or engineering, but not for more mundane things like plows, etc.&lt;br /&gt;
&lt;br /&gt;
In Graham v. John Deere, the history of the patent process is discussed, particularly Thomas Jefferson&#039;s outlook on the purpose of providing a patent. Jefferson made it clear that patents were only to be granted for inventions that furthered human knowledge and were new and useful. The granting of patents for small details, obvious improvements, or frivolous devices was neither worthwhile nor helpful. In A&amp;amp;P v. Supermarket Corp., Jefferson&#039;s sentiment is echoed, except the focus of the court is narrowed further to the important frontier of science and engineering. As Justice Douglas states, &amp;quot;the purpose is to promote the Progress of Science and Useful Arts,&amp;quot; and the two disciplines most associated with progress at that time (and still currently) are science and engineering. Even later, the court states, &amp;quot;patents serve a higher end-the advancement of science,&amp;quot; which make this point very clear.&lt;br /&gt;
&lt;br /&gt;
*Third, it dealt with the issue of the fact that any invention is basically a combination of old elements.&lt;br /&gt;
&lt;br /&gt;
The court&#039;s outlook on the evaluation of patents in regard to the combination of prior elements is best summarized in the following explanation. &amp;quot;The mere aggregation of a number of old parts or elements which, in the aggregation, peform or produce no new or different function or operation than that theretofore performed or produced by them is not patentable invention....only when the whole in some way exceeds the sum of its parts is the accumulation of old devices patentable.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
===35 USC 103 (1952)===&lt;br /&gt;
This section of the code was adopted in 1952 and prohibits a patent in a case where&lt;br /&gt;
:the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;== Argument For Patentability (for non-obviousness) ==&lt;br /&gt;
Graham&#039;s invention of a clamp for vibrating shank plows qualifies for a patent under 35 U.S.C 103, that is to say, it is non obvious.  In a prior patent, 2,493,811 (&#039;811), Graham disclose the invention of a mounting for a vibrating plow which shared some similar features.  The &#039;811 patent describes a mounting for a plow shank which allows the pivot upward if the shank encounters enough resistance in the ground.  This allows the shank to move upward instead of breaking.  The shank was placed atop the hinge plate, but not rigidly attached to it, being held in place instead by the spring rod.  The arrangement caused the shank to wobble because it was not firmly attached to the hinge plate.  In this set up, the shank also caused wear of the upper plate.  In this new invention, Graham has eliminated both these problems by placing the shank below the hinge plate, using bolts to rigidly attach it to the hinge plate.  The problems in the &#039;811 arrangement were significant, and no others had been able to solve them. Therefore, there was a &#039;long-felt unmet need&#039; in the industry for this product, and it took several years to find a suitable solution, the solution could not be considered obvious.  Graham&#039;s latest invention, then, qualifies for a patent under section 103.&lt;br /&gt;
== Argument Against Patentability (for obviousness) ==&lt;br /&gt;
Graham&#039;s latest invention does not meet the standard of non-obviousness required under section 103.  The design is an improvement on his previous invention, the clamp for vibrating shanks. That arrangement had several flaws which this design fixes by mounting the shank below the hinge plate and attaching it rigidly to that plate.  In this new arrangement, there are no new elements however.  It uses all the elements which were present in the previous invention, but places them more advantageously.  Further, no unexpected results result from this arrangement.  Therefore, this new arrangement could have be designed not by an inventor, but by anyone with the knowledge and skill of a mechanical engineer, and that person could have predicted the improvements that would result.  This new innovation of Graham&#039;s then, while useful and novel, does not qualify for a patent, because it is obvious under the standards laid out in section 103.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;*     The patent I choose, number 4304169, was for a method of noise reduction in a Maypole type braiding machine, the invention of Francis S. Cimprich et al.  This improvement of the braiding machine was found to be worthy of a patent in 1981 when the patent was granted, but it may not have been at various other points in U.S. history, due to the changing standards for patentability. We will consider here whether this invention would be considered patentable under the different standards in the cases Hotchkiss v. Greenwood, A. &amp;amp; P. Tea Co. v. Supermarket Corp., and Lyon v. Bausch &amp;amp; Lomb.&lt;br /&gt;
*     Certainly the idea of this type of braiding machine was not new at the time of Cimprich&#039;s patent.  The machine employs spools of wires or fibers which are wrapped around a thin core in order to produce rope, candle wicks, or in this case, hose.  The spools move in a circle around the hose, wrapping the wires or fibers in criss-crossed pattern.  This criss-cross is achieved by weaving the spools in and out from each other as they move around the hose.  This motion is guided by two interwoven sinusoidal paths cut in the supporting rings. The spools move along these paths and the fibers are interwoven, much in the same way ribbons are wrapped around a Maypole. This idea had existed at least since 1934, since it was patented in patent number 1,983,222[http://www.google.com/patents?id=jmt5AAAAEBAJ&amp;amp;pg=PA1&amp;amp;dq=1983222&amp;amp;source=gbs_selected_pages&amp;amp;cad=1#v=onepage&amp;amp;q&amp;amp;f=false].  &lt;br /&gt;
*     This idea had certainly existed before, but the Maypole braiding machines had always been very loud, putting the operators in danger of damaging their hearing.  Cimprich patented the idea of dampening the noise causing vibrations by placing a layer of visco-elastic material between the two plate which made up the ring, called the &#039;deck&#039; guiding the spools.  The motion of the spools in the paths on the deck is the main source of noise, so placing some viscoelastic material between the plates of the deck would absorb some of the noise-causing vibrations.  This was not the first attempt to reduce the noise produced by the braiding machine.  In 1975 Max Ostermann filled for a patent in Germany for a method of noise reduction in braiding machines.  His invention focused on the shape of the guides for the spools, but the patent also claims &amp;quot;the invention provides for the provision of a zone or portion of noise dampening material, particularly synthetic plastic material at the marginal portion of a respective sector of the plate, or where the contact point is located.&amp;quot;  The plate referred to here is not the deck, but a Geneva gear which transfers the motion of the spool.  The contact point is between the spool and the gear.  Thus some time prior to Cimprich&#039;s improvement, Ostermann had already come up with the idea of reducing the noise using a material which would absorb vibrations.  Ostermann had the idea to apply this method to the gears and the spool itself.  Cimprich later applied the idea to the deck, to which the gears and spools were attached.&lt;br /&gt;
*     In Hotchkiss v. Greenwood, the U.S. Supreme Court decided that the innovation of making clay doorknobs instead of metal or wooden ones was not patentable.  They claimed that the improvement of device by substituting one material for another could not be patented, if the improvement derived only from the a more suitable material.  The idea of using a better material does not contain the ingenuity characteristic of an invention, the court said.  They proposed the following criteria for determining whether an idea is patentable: if it is the work of a skilled mechanic, then the idea is not patentable.  If this standard were applied to the case of the noise-reduction techniques in Maypole braiders, Cimprich&#039;s innovation would not be patentable.  Cimprich took the existing idea of using some plastic material as a dampener, and applied it to a different part of the machine.  Presumably, a skilled mechanic, seeing how vibration were dampened in one part of a machine, could apply that method to a nearby component on the machine, and thus reduce the vibration, and thus the noise, even further.  Since this does not require an inventor, but only a skilled mechanic, this innovation would not be patentable.  &lt;br /&gt;
*     A century later, in 1950, the U.S. Supreme Court decided in the case A. &amp;amp; P. Tea Co. v. Supermarket Corp. that a patent for a particular cashier&#039;s counter was not valid, because it was made up of elements which were all previously known and used.  The court decided that a combination of known elements must have produce some &#039;unusual or surprising consequences&#039; if it is to be patentable.  They decided this in order to be consistent with the function of the patent, established by the Constitution, which is to add to the sum of useful knowledge.  In the case of the braiders, again Cimprich&#039;s innovation would again be unpatentable.  He took an existing method for noise reduction, and applied it to a different part of the machine.  From his patent we can gather that the result of this is just what we might expect, the reduction of noise in that part of the machine.  Since the use of existing ideas does not produce any unpredictable result, the innovation, while useful, is not the subject for a patent.&lt;br /&gt;
&lt;br /&gt;
*     By 1955, a new code pertaining to patent law had been passed by Congress, which included &#039;non-obviousness&#039; a criterion necessary for patentability.  In the case Lyon v. Bausch &amp;amp; Lomb, the U.S. Court of Appeals Second Circuit decided that a particular method of attaching a reflective coating to glass using heat was patentable, despite the fact that others had come up with the idea for this method previously, and had even experimented with the method.  The others had not been able to make the method effective, and so had abandoned their attempts.  Lyon then managed to use the method, and subsequently patented it.  The court judged that the previous attempts did not &#039;anticipate&#039; Lyon&#039;s innovation, because they had abandoned the idea that the method could be effective.  Lyon&#039;s was entitled to the patent, because their innovation clearly was not obvious, since others had tried and failed to use that method.  Under this standard, Cimprich&#039;s invention would be patentable.   People had desired to reduce the excessive noise of braiding machines for a long time, and no one had done so satisfactorily.  Although Cimprich&#039;s innovation may seem simple, no one had thought to or been able to construct a deck which included visco-elastic material to reduce vibrations, despite the fact that people had been searching for methods to reduce noise (demonstrated by Ostermann&#039;s patent).  Thus Cimprich&#039;s idea should be considered non-obvious and thus the subject for a patent.&lt;br /&gt;
*    Cimprich&#039;s patent for reducing noise in braiding machines is valid today, but would not have been prior to the change is in patent law made by Congress in 1952.  The standards used in Hotchkiss v. Greenwood and in A. &amp;amp; P. Tea Co. v. Supermarket Corp., if applied to this patent, would have found it invalid.&lt;br /&gt;

Patent 4304169 [http://www.google.com/patents/about?id=cissAAAAEBAJ&amp;amp;dq=4304169]&lt;br /&gt;
&lt;br /&gt;
Issue date: Dec 8, 1981&lt;br /&gt;
&lt;br /&gt;
*This machine makes hose continuously by criss-crossing strands and wrapping them around a cylindrical core (mandrel) which is pulled through the center of the machine.  The strands (of fiber, plastic, etc) are on spools, and these spools rotate on a ring concentric to the mandrel, winding the fibers around the mandrel as the mandrel is pulled through the ring.  Half of the the spools are traveling clockwise, and half counter clockwise, weaving in between each other to create the criss-crossed pattern.&lt;br /&gt;
*This patent is for a method of reducing noise on this type of machine.  These &#039;Maypole&#039; braiding machines traditionally produced a large amount of noise when operating, amounts which could damage the hearing of the operators.  This patent uses the idea of placing some visco-elastic material between certain plates in order to dissipate the noise energy.&lt;br /&gt;

Since the use of existing ideas does not produce any unpredictable result, the innovation, while useful, is not the subject for a patent.&lt;br /&gt;
&lt;br /&gt;
*     By 1955, a new code pertaining to patent law had been passed by Congress, which included &#039;non-obviousness&#039; a criterion necessary for patentability.  In the case Lyon v. Bausch &amp;amp; Lomb, the U.S. Court of Appeals Second Circuit decided that a particular method of attaching a reflective coating to glass using heat was patentable, despite the fact that others had come up with the idea for this method previously, and had even experimented with the method.  The others had not been able to make the method effective, and so had abandoned their attempts.  Lyon then managed to use the method, and subsequently patented it.  The court judged that the previous attempts did not &#039;anticipate&#039; Lyon&#039;s innovation, because they had abandoned the idea that the method could be effective.  Lyon&#039;s was entitled to the patent, because their innovation clearly was not obvious, since others had tried and failed to use that method.  Under this standard, Cimprich&#039;s invention would be patentable.   People had desired to reduce the excessive noise of braiding machines for a long time, and no one had done so satisfactorily.  Although Cimprich&#039;s innovation may seem simple, no one had thought to or been able to construct a deck which included visco-elastic material to reduce vibrations, despite the fact that people had been searching for methods to reduce noise (demonstrated by Ostermann&#039;s patent).  Thus Cimprich&#039;s idea should be considered non-obvious and thus the subject for a patent.&lt;br /&gt;
*    Cimprich&#039;s patent for reducing noise in braiding machines is valid today, but would not have been prior to the change is in patent law made by Congress in 1952.  The standards used in Hotchkiss v. Greenwood and in A. &amp;amp; P. Tea Co. v. Supermarket Corp., if applied to this patent, would have found it invalid.&lt;br /&gt;

Patent 4304169 [http://www.google.com/patents/about?id=cissAAAAEBAJ&amp;amp;dq=4304169]&lt;br /&gt;
&lt;br /&gt;
Issue date: Dec 8, 1981&lt;br /&gt;
&lt;br /&gt;
*This machine makes hose continuously by criss-crossing strands and wrapping them around a cylindrical core (mandrel) which is pulled through the center of the machine.  The strands (of fiber, plastic, etc) are on spools, and these spools rotate on a ring concentric to the mandrel, winding the fibers around the mandrel as the mandrel is pulled through the ring.  Half of the the spools are traveling clockwise, and half counter clockwise, weaving in between each other to create the criss-crossed pattern.&lt;br /&gt;
*This patent is for a method of reducing noise on this type of machine.  These &#039;Maypole&#039; braiding machines traditionally produced a large amount of noise when operating, amounts which could damage the hearing of the operators.  This patent uses the idea of placing some visco-elastic material between certain plates in order to dissipate the noise energy.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;*     The patent I choose, number 4304169, was for a method of noise reduction in a Maypole type braiding machine, the invention of Francis S. Cimprich et al.  This improvement of the braiding machine was found to be worthy of a patent in 1981 when the patent was granted, but it may not have been at various other points in U.S. history, due to the changing standards for patentability. We will consider here whether this invention would be considered patentable under the different standards in the cases Hotchkiss v. Greenwood, A. &amp;amp; P. Tea Co. v. Supermarket Corp., and Lyon v. Bausch &amp;amp; Lomb.&lt;br /&gt;
*     Certainly the idea of this type of braiding machine was not new at the time of Cimprich&#039;s patent.  The machine employs spools of wires or fibers which are wrapped around a thin core in order to produce rope, candle wicks, or in this case, hose.  The spools move in a circle around the hose, wrapping the wires or fibers in criss-crossed pattern.  This criss-cross is achieved by weaving the spools in and out from each other as they move around the hose.  This motion is guided by two interwoven sinusoidal paths cut in the supporting rings. The spools move along these paths and the fibers are interwoven, much in the same way ribbons are wrapped around a Maypole. This idea had existed at least since 1934, since it was patented in patent number 1,983,222[http://www.google.com/patents?id=jmt5AAAAEBAJ&amp;amp;pg=PA1&amp;amp;dq=1983222&amp;amp;source=gbs_selected_pages&amp;amp;cad=1#v=onepage&amp;amp;q&amp;amp;f=false].  &lt;br /&gt;
*     This idea had certainly existed before, but the Maypole braiding machines had always been very loud, putting the operators in danger of damaging their hearing.  Cimprich patented the idea of dampening the noise causing vibrations by placing a layer of visco-elastic material between the two plate which made up the ring, called the &#039;deck&#039; guiding the spools.  The motion of the spools in the paths on the deck is the main source of noise, so placing some viscoelastic material between the plates of the deck would absorb some of the noise-causing vibrations.  This was not the first attempt to reduce the noise produced by the braiding machine.  In 1975 Max Ostermann filled for a patent in Germany for a method of noise reduction in braiding machines.  His invention focused on the shape of the guides for the spools, but the patent also claims &amp;quot;the invention provides for the provision of a zone or portion of noise dampening material, particularly synthetic plastic material at the marginal portion of a respective sector of the plate, or where the contact point is located.&amp;quot;  The plate referred to here is not the deck, but a Geneva gear which transfers the motion of the spool.  The contact point is between the spool and the gear.  Thus some time prior to Cimprich&#039;s improvement, Ostermann had already come up with the idea of reducing the noise using a material which would absorb vibrations.  Ostermann had the idea to apply this method to the gears and the spool itself.  Cimprich later applied the idea to the deck, to which the gears and spools were attached.&lt;br /&gt;
*     In Hotchkiss v. Greenwood, the U.S. Supreme Court decided that the innovation of making clay doorknobs instead of metal or wooden ones was not patentable.  They claimed that the improvement of device by substituting one material for another could not be patented, if the improvement derived only from the a more suitable material.  The idea of using a better material does not contain the ingenuity characteristic of an invention, the court said.  They proposed the following criteria for determining whether an idea is patentable: if it is the work of a skilled mechanic, then the idea is not patentable.  If this standard were applied to the case of the noise-reduction techniques in Maypole braiders, Cimprich&#039;s innovation would not be patentable.  Cimprich took the existing idea of using some plastic material as a dampener, and applied it to a different part of the machine.  Presumably, a skilled mechanic, seeing how vibration were dampened in one part of a machine, could apply that method to a nearby component on the machine, and thus reduce the vibration, and thus the noise, even further.  Since this does not require an inventor, but only a skilled mechanic, this innovation would not be patentable.  &lt;br /&gt;
*     A century later, in 1950, the U.S. Supreme Court decided in the case A. &amp;amp; P. Tea Co. v. Supermarket Corp. that a patent for a particular cashier&#039;s counter was not valid, because it was made up of elements which were all previously known and used.  The court decided that a combination of known elements must have produce some &#039;unusual or surprising consequences&#039; if it is to be patentable.  They decided this in order to be consistent with the function of the patent, established by the Constitution, which is to add to the sum of useful knowledge.  In the case of the braiders, again Cimprich&#039;s innovation would again be unpatentable.  He took an existing method for noise reduction, and applied it to a different part of the machine.  From his patent we can gather that the result of this is just what we might expect, the reduction of noise in that part of the machine.  Since the use of existing ideas does not produce any unpredictable result, the innovation, while useful, is not the subject for a patent.&lt;br /&gt;

The spools move in a circle around the hose, wrapping the wires or fibers in criss-crossed pattern.  This criss-cross is achieved by weaving the spools in and out from each other as they move around the hose.  This motion is guided by two interwoven sinusoidal paths cut in the supporting rings. The spools move along these paths and the fibers are interwoven, much in the same way ribbons are wrapped around a Maypole. This idea had existed at least since 1934, since it was patented in patent number [http://www.google.com/patents?id=jmt5AAAAEBAJ&amp;amp;pg=PA1&amp;amp;dq=1983222&amp;amp;source=gbs_selected_pages&amp;amp;cad=1#v=onepage&amp;amp;q&amp;amp;f=false].  &lt;br /&gt;
