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.

Most firms are aiming their newest tools at the work they already do — pouring their most powerful technology into running the same tasks a little faster. But when everyone automates the same tasks at once, no one pulls ahead. That reaches the future a little faster while leaving a firm’s largest opportunity untouched — and that opportunity isn’t doing more of the existing work, but transforming how the high-value work gets done.

Artificial intelligence is rapidly embedding itself into legal workflows, but much of the conversation treats all use cases as if they carry the same level of risk, even if they do not. The more useful question is not whether AI works, but where it can be safely applied and where it cannot.
