Appeal No. 1997-2242 Page 7
Application No. 08/084,370
presenting a prima facie case of obviousness. Note In re
Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.
1992). If that burden is met, the burden then shifts to the
applicant to overcome the prima facie case with argument
and/or evidence. Obviousness is then determined on the basis
of the evidence as a whole. See id.; In re Hedges, 783 F.2d
1038, 1039, 228 USPQ 685, 686 (Fed. Cir. 1986); In re
Piasecki, 745 F.2d 1468, 1472, 223 USPQ 785, 788 (Fed. Cir.
1984); and In re Rinehart, 531 F.2d 1048, 1052, 189 USPQ 143,
147 (CCPA 1976).
