II.THE BASIC FACTUAL INQUIRES OF GRAHAM v. JOHN DEERE CO.

An invention that would have been obvious to a person of ordinary skill at the time of the invention is not patentable. See 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a). As reiterated by the Supreme Court in KSR, the framework for the objective analysis for determining obviousness under 35 U.S.C. 103 is stated in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966). Obviousness is a question of law based on underlying factual inquiries. The factual inquiries enunciated by the Court are as follows:

  • (A) Determining the scope and content of the prior art; and
  • (B) Ascertaining the differences between the claimed invention and the prior art; and
  • (C) Resolving the level of ordinary skill in the pertinent art.

Objective evidence relevant to the issue of obviousness must be evaluated by Office personnel. Id. at 17-18, 148 USPQ at 467. Such evidence, sometimes referred to as “secondary considerations,” may include evidence of commercial success, long-felt but unsolved needs, failure of others, and unexpected results. The evidence may be included in the specification as filed, accompany the application on filing, or be provided in a timely manner at some other point during the prosecution. The weight to be given any objective evidence is made on a case-by-case basis. The mere fact that an applicant has presented evidence does not mean that the evidence is dispositive of the issue of obviousness.

The question of obviousness must be resolved on the basis of the factual inquiries set forth above. While each case is different and must be decided on its own facts, the Graham factors, including secondary considerations when present, are the controlling inquiries in any obviousness analysis. The Graham factors were reaffirmed and relied upon by the Supreme Court in its consideration and determination of obviousness in the fact situation presented in KSR, 550 U.S. at 406-07, 82 USPQ2d at 1391 (2007). The Supreme Court has utilized the Graham factors in each of its obviousness decisions since Graham. See Sakraida v. Ag Pro, Inc., 425 U.S. 273, 189 USPQ 449, reh’g denied, 426 U.S. 955 (1976);Dann v. Johnston, 425 U.S. 219, 189 USPQ 257 (1976); and Anderson’s-Black Rock, Inc. v. Pavement Salvage Co., 396 U.S. 57, 163 USPQ 673 (1969). As stated by the Supreme Court in KSR, “While the sequence of these questions might be reordered in any particular case, the [Graham] factors continue to define the inquiry that controls.”KSR, 550 U.S. at 407, 82 USPQ2d at 1391.
