examiner.
In rejecting claims under 35 U.S.C. § 103, the examiner
bears the initial burden of presenting a prima facie case of
obviousness (see In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d
1955, 1956 (Fed. Cir. 1993); In re Oetiker, 977 F.2d 1443,
1446, 24 USPQ2d 1443, 1445 (Fed. Cir. 1992)), which is
established when the teachings of the prior art itself would
appear to have suggested the claimed subject matter to one of
ordinary skill in the art (see In re Bell, 991 F.2d 781, 783,
26 USPQ2d 1529, 1531 (Fed. Cir. 1993)). The conclusion that
the claimed subject matter is prima facie obvious must be
supported by evidence, as shown by some objective teaching in
the prior art or by knowledge generally available to one of
ordinary skill in the art that would have led that individual
to combine the relevant teachings of the references to arrive
at the claimed invention.
See In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598
(Fed. Cir. 1988).
