Design Patent Prior Art Must Be From Same or Analogous Field as Claimed Article of Manufacture

Finding that the Patent Trial & Appeal Board (Board) applied an erroneous interpretation of claim scope, the US Court of Appeals for the Federal Circuit reversed a Board decision upholding an examiner’s rejection of a lip implant design patent as anticipated by a non-analogous art tool. In re: SurgiSil, Case No. 20-1940 (Fed. Cir. Oct. 4, 2021) (Moore, C.J.)

SurgiSil filed a design application for a lip implant shaped like a generally cylindrical rod that tapered to a point at each end. The examiner rejected the patent as anticipated by a “stump,” an art tool of similar, almost identical, shape used for smoothing and blending areas of pastel or charcoal. SurgiSil appealed the rejection to the Board. The Board affirmed the rejection, finding that the differences in the shapes of SurgiSil’s lip implant and the art tool were minor. The Board rejected SurgiSil’s argument that the two articles of manufacture were “very different,” reasoning that it is irrelevant whether a prior art reference is analogous for anticipation purposes. SurgiSil appealed.

Reviewing the Board’s legal conclusions de novo, the Federal Circuit found that the Board erred as a matter of law. Citing 35 U.S.C. § 171(a) and the 1871 Supreme Court decision in Gorham Co. v. White, the Court explained that a design patent claim does not cover the design in the abstract, and that it is limited to the particular article of manufacture identified in the claim. The Court concluded that the claimed design was limited to a lip implant, did not cover other articles of manufacture and that the Board’s decision therefore rested on an erroneous interpretation of the claim’s scope.
