Appeal No. 98-1200 Application 08/589,780 The appellant's position here is well taken. Staniszewski and Lewis contain no suggestion whatsoever of a mounting device having means for expanding into fast, radial- gripping engagement with the bore of an element being mounted on a shaft. The examiner's apparent contention that Staniszewski's nut members 36 and 38, as modified in view of Lewis to include shoulders extending into bore 11 of element 10, would expand into fast, radial-gripping engagement with the bore if they were made of a plastic or malleable material (see pages 3 and 4 in the answer) is not persuasive. Even if these nut members were made of a plastic or malleable material, it would be unduly speculative to conclude that they would expand into a fast, radial-gripping engagement with the bore. In short, Staniszewski and Lewis simply do not provide the factual basis necessary to conclude that the mounting device recited in claim 18, with its "means for . . . expanding into fast, radial-gripping engagement with said bore," would have been obvious to one of ordinary skill in the art. Accordingly, we shall not sustain the standing 35 U.S.C. 5Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
