Appeal 2007-1313 Application 10/162,098 PRINCIPLES OF LAW “Section 103 forbids issuance of a patent when ‘the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.’” KSR Int'l Co. v. Teleflex Inc., 127 S.Ct. 1727, 1734, 82 USPQ2d 1385, 1391 (2007).

The Court noted that “[t]o facilitate review, this analysis should be made explicit.” Id., citing In re Kahn, 441 F.3d 977, 988, 78 USPQ2d 1329, 1336 (Fed.
