“Whether the rigid approach to evaluating the obviousness of designs under In re Rosen, 673 F.2d 388, 391 (CCPA 1982) and Durling v. Spectrum Furniture Co., Inc., 101 F.3d 100 (Fed Cir. 1996) is consistent with the Supreme Court’s interpretation of 35 U.S.C. § 103 in KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398 (2007).”
“What standard, consistent with KSR and 35 U.S.C. § 171, should replace the current requirement that a patent challenger identify a primary reference that is basically the same as the claimed design as a prerequisite to evaluating obviousness and the further limitation that allows modification of the primary reference only if there is a secondary reference that is ‘so related’ to the primary reference that the appearance of certain ornamental features in one would suggest the application of those features to the other.”
