Appeal 2007-1802
Application 10/648,575
Based on the contentions of the Examiner and the Appellants, the
issue before us is: Has the Examiner made accurate and sufficient factual
findings such that it is reasonable to conclude that one of ordinary skill in
the art would have been motivated to combine the teachings of the
references in the manner claimed within the meaning of 35 U.S.C. § 103?
We answer this question in the affirmative.
Under 35 U.S.C. § 103, the factual inquiry into obviousness requires a
determination of: (1) the scope and content of the prior art; (2) the
differences between the claimed subject matter and the prior art; (3) the level
of ordinary skill in the art; and (4) secondary considerations. Graham v.
John Deere Co. of Kansas City, 383 U.S. 1, 17-18, 148 USPQ 459, 467
(1966). “[A]nalysis [of whether the subject matter of a claim would have
been obvious] need not seek out precise teachings directed to the specific
subject matter of the challenged claim, for a court can take account of the
inferences and creative steps that a person of ordinary skill in the art would
employ.” KSR Int’l Co. v. Teleflex, Inc., 127 S. Ct. 1727, 1740-41, 82

USPQ2d 1641, 1645 (Fed. Cir. 2006)(“The motivation need not be found in
the references sought to be combined, but may be found in any number of
sources, including common knowledge, the prior art as a whole, or the
nature of the problem itself.”); In re Bozek, 416 F.2d 1385, 1390, 163 USPQ
545, 549 (CCPA 1969)(“Having established that this knowledge was in the
art, the examiner could then properly rely, as put forth by the solicitor, on a
conclusion of obviousness ‘from common knowledge and common sense of
