Appeal No. 1996-4071 Page 9
Application No. 08/292,692
Dembiczak, 175 F.3d 994, 999, 50 USPQ2d 1614, 1617 (Fed. Cir.
1999); In re Rouffet, 149 F.3d 1350, 1356, 47 USPQ2d 1453,
1456 (Fed. Cir. 1998). Whether the evidence of a teaching or
suggestion to combine comes from the references themselves,
the knowledge of one of ordinary skill in the art, or from the
nature of the problem to be solved, the showing of evidence
must be clear and particular. Dembiczak, 175 F.3d at 999, 50
USPQ2d at 1617. Moreover, the determination of obviousness
must be based on facts, and not on unsupported generalities.
See In re Freed, 425 F.2d 785, 787, 165 USPQ 570, 571 (CCPA
1970).
