PRINCIPLES OF LAW
In rejecting claims under 35 U.S.C. § 103, the Examiner bears the
initial burden of establishing a prima facie case of obviousness. In re
Piasecki, 745 F.2d 1468, 1472, 223 USPQ 785, 788 (Fed. Cir. 1984). The
Examiner can satisfy this burden by showing some articulated reasoning
with some rational underpinning to support the legal conclusion of
obviousness. KSR Int’l. v. Teleflex Inc., 127 S. Ct. 1727, 1741, 82 USPQ2d
1385, 1396 (2007) (citing In re Kahn, 441 F.3d 977, 988, 78 USPQ2d 1329,
1336 (Fed. Cir. 2006)). Only if this initial burden is met does the burden of
coming forward with evidence or argument shift to the Appellant. Piasecki,
745 F.2d at 1472, 223 USPQ at 788. Thus, the Examiner must not only
assure that the requisite findings are made, based on evidence of record, but
must also explain the reasoning by which the findings are deemed to support
the Examiner’s conclusion.
