More than twenty interested parties have filed amicus curiae briefs in a recent patent case, KSR v. Teleflex (S.Ct. 2006, Docket No. 04-1350). Leave to appeal to the U.S. Supreme Court was granted to clarify the standard of obviousness for a patent claim as propounded by the Court of Appeals for the Federal Circuit. The question presented to the Supreme Court is whether the Federal Circuit has erred in holding that a claimed invention cannot be held "obvious," and thus unpatentable under 35 U.S.C. 103(a) in the absence of some proven "teaching, suggestion, or motivation" that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed. Oral arguments in KSR v. Teleflex are set for November 28, 2006.
A Supreme Court holding that overrules the present Federal Circuit standard by eliminating the "motivation test" will profoundly and retroactively change how the U.S. Patent and Trademark Office and the courts view the standard of obviousness as applied to already granted patents. A reversal will call into question the validity of literally hundreds of thousands of patents, issued after the CAFC added the "motivation test" in 1993. Any arguments presented during patent application prosecution will undergo close scrutiny and any reliance on the Federal Circuit standard will provide a basis to attack patent validity, should the Supreme Court change the standard. The Supreme Court is expected to decide the KSR case during its present term, ending in June 2007.
