  • Read Bonito Boats v. Thunder Craft, 489 U.S. 141 (1989)
    • There certainly will be plenty of confusing stuff in this case since you don't know any patent law or much judicial procedure yet. The main point of reading the case is that it is a good explanation of the constitutional basis for patent law, some relevant sections of the US Code, the history of patent law, etc. Whoever the unlucky person is that is called on to discuss this will sort of be on the spot, that's the way it goes...
    • If you don't like the formatting in the wiki, you can get a better formatted version through Westlaw. There is a "find a document by citation" search box on the left side of the page. This should lead to the case as well.

  • Find and read a US patent that was issued between January 1, 1980 and January 1, 1990. It should involve a technical subject area in which you have some competence and interest. This patent will serve as the basis for many of your assignments, so spend a little time to pick one that you sort of like and think is complicated enough to be interesting, yet simple enough that you will be able to add or remove features from it. An example of the type of homework you will have to do will be to describe another invention that would have made this one clearly not patentable, or an invention in a related field that would not bar its patentability, etc.
  • On your wiki page (log in and click on your name along the top) edit your page to add a description, in plain English, of what the invention is. Format it in a reasonable manner. The wiki stuff is easy to modify and re-organize, but it may be worth giving some thought to how you will organize it, e.g., links to each different homework, related things on a single page, etc.

  • Read Lyon v. Bausch & Lomb, 224 F.2d 530 (1955)
  • Using your patent from the homework due on Monday, obtain some (2 or 3 if they are of normal length) of the References Cited, preferably other patents. Using those references, would the patent you chose be patentable under the analysis of Hotchkiss or A&P? Would it satisfy the nonobviousness requirement of 35 USC 103 under Lyon? If the answer is different, which I suspect would be the normal case, what evolution of the standards of nonobviousness (referred to in the old cases as inventivness or something similar) lead to the change? As a rule of thumb, I would say the analysis for each case would take about page, with perhaps a common page or two description of what the references disclose.
    • Note, it may be the case that the patent you chose doesn't really work for this homework. In that case, if you use google patents, one feature is that you can find the later patents that cite your patent. It is allowable to do the analysis described above relating to the patentability of the later patent that cites your patent.
    • If that still doesn't work, then just find a completely different one and start from there. If you are totally stuck with what to do, then contact me.

We won't be threading our way through so many cases in all the other areas of patent law, but the evolution of non-obviousness and the idea of what's an invention is 1) interesting and 2) good for you to read the cases to build up all the ancillary sort of knowledge to be able to read cases in the rest of this class efficiently. Graham is long, but the other two are progressively shorter. If you can reconcile the third case with the first two, I would be very interested in hearing your take on it.
