citing In re Kotzab, 217 F.3d 1365, 1370, 55 USPQ2d 1313 (Fed.
Cir. 2000). See also In re Thrift, 298 F. 3d 1357, 1363, 63
USPQ2d 2002, 2008 (Fed. Cir. 2002). These showings by the
examiner are an essential part of complying with the burden of
presenting a prima facie case of obviousness. Note In re
Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.

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 and the relative persuasiveness of the
arguments. 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,
