Appeal 2006-2516 Application 10/191,449 5 USPQ2d 1529, 1532 (Fed. Cir. 1988) ("Evidence that supports, rather than negates, patentability must be fairly considered."). Therefore, we conclude that the appealed claims are patentable over the combined teachings of Kumagai and Halpern1 The rejection is reversed. REVERSED tf OBLON, SPIVAK, MCCLELLAND, MAIER & NEUSTADT, P.C. 1940 DUKE STREET ALEXANDRIA, VA 22314 1 For the sake of completeness, we note that during oral hearing, Appellants’ counsel also argued that the Examiner had relied upon improper hindsight reasoning and, therefore, had not established a prima facie showing of obviousness. In particular, it was noted that the Examiner failed to explain why one of ordinary skill in the art, in considering the problem of bisurea by-product formation, would have looked to Halpern which discloses alkoxylation of PVA, acetylation and reaction with isocyanate to produce a product which is said to be useful in the manufacture of foam products. In addition, the Examiner did not explain why one of ordinary skill in the art would apply Halpern’s teaching relating to polyvinyl alcohol particle sizes to Kumagai’s ethylene/vinyl alcohol copolymer. We are in agreement with Appellants that the only relationship between an ethylene/vinyl alcohol copolymer and polyvinyl alcohol appears to emanate from Appellants’ disclosure. In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1783-74 (Fed. Cir. 1992) (“The mere fact that the prior art may be modified in the manner suggested by the Examiner does not make the modification obvious unless the prior art suggested the desirability of the modification.”). However, we do not find this argument on the written record before us. 5Page: Previous 1 2 3 4 5Last modified: November 3, 2007
