Appeal No. 1997-0158 Application No. 08/026,581 Appellants appear to argue that the production of a cis- olefin with a selectivity of more than 99% as shown in examples 1, 5 and 6 is not taught or suggested by the applied prior art. This argument is without any merit since the claims do not require such selectivity. In re Self, 671 F.2d 1 1344, 1350, 213 USPQ 1, 7 (CCPA 1982). Nor do the claims recite reaction conditions, catalysts and/or specific reactants, which are useful for obtaining such selectivity. Id. To the extent that appellants may have relied on this improvement as an unexpected result, we are convinced that appellants have not carried their burden of proof. In re Klosak, 455 F.2d 1077, 1080, 173 USPQ 14, 16 (CCPA 1972)(the burden of proving unexpected results rests on the party who asserts them); In re Heyna, 360 F.2d 222, 228, 149 USPQ 692, 1Should appellants recite such a selectivity limitation in their claims, the examiner must determine whether the claimed subject matter is commensurate in the scope with an enabling disclosure in the specification within the meaning of 35 U.S.C. § 112, first paragraph. The examiner must determine whether more than 99% selectivity can be achieved for desired cis- olefin products with the reactants, catalysts and conditions covered by the claims, without undue experimentation. 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
