Graham v. John Deere Co., 383 U.S. 1 (1966), was a case in which the United States Supreme Court clarified the nonobviousness requirement in United States patent law,[1] set forth 14 years earlier in Patent Act of 1952 and codified as 35 U.S.C. § 103.[2]
Although the Court confirmed that non-obviousness is a question of law, it held that §103 required a determination of the following questions of fact to resolve the issue of obviousness:
In addition, the Court mentioned "secondary considerations" which could serve as evidence of nonobviousness. These are known as "Graham's factors":
The Court stated, that the purpose of these factors is to "guard against slipping into use of hindsight" when making a determination of obviousness.[3]
The SCOTUS also proposed the inducement standard, suggesting that patent law's nonobviousness doctrine is meant to restrict the award of patents to only "those inventions which would not be disclosed or devised but for the inducement of a patent." Although, the Graham's factors have been cited numerous times by patent examiners and courts, the inducement standard has been largely ignored.[4]
Despite providing these useful guidelines, the Court also recognized that these questions would likely need to be answered on a case-by-case basis, first by the United States Patent and Trademark Office (USPTO), then by the courts. The "non-obviousness criteria" laid out in Graham were complemented in 2007 by "obviousness criteria" in another US Supreme Court case (see KSR v. Teleflex).
