KSR Int'l Co. v. Teleflex Inc. et al.: Supreme Court Clarifies Obviousness

Before the Supreme Court's April 30, 2007 decision in <i>KSR Int'l Co. v. Teleflex Inc. et al.</i>, 127 S.Ct. 1727 (2007) virtually all patent attorneys were on the edge of their seats. The decision was a clear indication that the Supreme Court disfavored the current state of the law that had been developed by the Federal Circuit for determining whether a patent is invalid for obviousness under 35 U.S.C. &sect;103. The Supreme Court pointed to numerous errors in the Federal Circuit decision and characterized as 'rigid,' 'formalistic,' 'narrow,' 'constricted,' and 'flaw[ed]' the Federal Circuit's requirement that there be proof the claimed combination of elements was arrived at due to a teaching, suggestion, or motivation to combine features from prior art references. <i>Id.</i> at 1739, 1741-42. Instead, the Supreme Court imposed a more flexible approach that sought to emphasize its earlier decisions on obviousness over tests the Federal Circuit had developed to apply the law set forth in those decisions.
