Appeal No. 1996-1735 Application No. 08/184,526 Accordingly, we reverse the examiner’s decision rejecting claim 3 under 35 U.S.C. § 102(b). We turn next to the examiner’s rejection of claims 4 through 9 under 35 U.S.C. § 103 as unpatentable over the disclosure of the Weiss reference. Appellants do not argue that the limitations recited in claims 5 through 9 impart patentability over the Weiss reference. What appellants argue is that the Weiss reference would not have rendered a polyamide curative having “the ratio of amine group equivalents to acid group equivalents...from about 1.20:1.00 to about 1.80:1.00” recited in claim 4 obvious to one of ordinary skill in the art. However, as indicated supra, we find that the Weiss reference describes a polyamide curative having the amine group equivalents to acid group equivalents ratio of 2.00:1.00, which is very close to the claimed ratio of “about 1.80:1.00". We further find that the polyamide curative described in the Weiss reference can be produced by a condensation reaction between imide or anhydride with an excess amine, “namely little above the stoichiometrically calculated quantity up to a very substantial excess, i.e. up to a 100 molar percent excess.” See Answer, page 3, together 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
