n.14 (Fed. Cir. 1992), citing In re Gordon, 733 F.2d 900, 902,
221 USPQ 1125, 1127 (Fed. Cir. 1984). "Obviousness may not be

37 USPQ2d at 1239, citing W. L. Gore & Assocs., 721 F.2d at
1551, 1553, 220 USPQ at 311, 312-13. In addition, our
reviewing court requires the PTO to make specific findings on
a suggestion to combine prior art references. In re
