Appeal No. 2001-0305 Page 7 Application No. 09/077,356 Appellant's only other argument against the examiner's rejection is that the Soviet patent does not suggest that the coupling described therein can be used to couple parts made from different materials (brief, p. 5).

Cir. 1992) ("there must be some suggestion for [combining prior art references], found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art"); In re Nilssen, 851 F.2d 1401, 1403, 7 USPQ2d 1500, 1502 (Fed.
