Appeal No. 1995-4675 Application No. 07/875,452 as here, is not sufficient to rebut a prima facie case of obviousness. In re Dill, 604 F.2d 1356, 1361, 202 USPQ 805, 808 (CCPA 1979). Indeed, for all we know based upon the record before us including the proffered declaration evidence, the unexpected results shown in the Parks Declarations are not exhibited by amorphous nylons generally but only by the specifically tested amorphous nylon “Selar PA.” Thus, the fatal deficiency of the appellants’ declaration evidence of nonobviousness is that it fails to show unexpected results for amorphous nylons as a class in accordance with the here claimed invention. In re Hostettler, 429 F.2d 464, 466, 166 USPQ 558, 560 (CCPA 1970). The circumstances recounted above lead us to the ultimate determination that all the evidence of record, on balance, weighs most heavily in favor of an obviousness conclusion. We shall sustain, therefore, the § 103 rejections of claims 1 through 3, 15 and 16 as being unpatentable over Tanner in view of Deak, of claims 4 and 5 as being unpatentable over these references and further in view of Gibbons and of claims 6 through 14, 17 and 18 as being unpatentable over Tanner, Deak and Gibbons and further in view of the appellants’ 12Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
