NONOBVIOUSNESS

The main historical cases:

• 1850: Hotchkiss v. Greenwood (Hotchkiss v. Greenwood (full text)) Established the "nonobviousness" language the subsequently became codified.
• 1966: GRAHAM V. JOHN DEERE CO (GRAHAM V. JOHN DEERE CO (full text)) The fundamental inquiries are
  • scope and content of the prior art;
  • differences between the prior art and the claims at issue;
  • level of ordinary skill in the pertinent art; and,
  • secondary considerations, including:
    • commercial success of the invention;
    • long-felt but unsolved needs;
    • failure of others to find a solution, etc.
