Appeal No. 2002-2063 Application No. 09/635,093 have not compared the other, non-high boiling solvents of Furness. See In re Simmons, 739 F.2d at 1575, 222 USPQ at 746 (" A nexus between the merits of the claimed invention and evidence of secondary considerations is required in order for the evidence to be given substantial weight in an obviousness decision."). Consequently, we find that, on balance, the praise, properties, and commercial results are insufficient to overcome the prima facie case of obviousness as they are not commensurate in scope with the claimed subject matter In re Grasselli, 713 F.2d 731, 743, 218 USPQ 769, 778 (Fed. Cir. 1983); In re Clemens, 622 F.2d 1029, 1035, 206 USPQ 289, 296 (CCPA 1980) and do not compare the closest prior art. Appellants’ Point 12: The Sherwood Patent (Appeal Brief, page 27). The appellants urge that the examiner erred in not considering the teachings of the Sherwood patent. While we agree that Sherwood is relevant in that it is “in line with the general idea that the preferred solvent for the polyisocyanate component is a high-boiling non-polar aromatic hydrocarbon” (Appeal Brief, page 8, lines 23 et seq.), this teaching still does not overcome the plain meaning of the teaching in Furness to use whatever solvents are suitable. We therefore are not persuaded by this 28Page: Previous 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 NextLast modified: November 3, 2007
