Kevin Collins: An Initial Comment on King Pharmaceuticals: The Printed Matter Doctrine as a Structural Doctrine and Its Implications for Prometheus Laboratories

By Dennis Crouch

Kevin Collins has written a new Patently-O Patent Law Journal essay discussing the recent decision in King Pharmaceuticals. [Read the full essay]

On August 2, 2010, the Federal Circuit affirmed the district court?s summary judgment of patent invalidity in King Pharmaceuticals, Inc. v. Eon Labs, Inc. King Pharmaceuticals is most notable for its extension of the printed matter doctrine from objects claims that recite written texts as limitations to method claims that recite speech acts as limitations.

This Essay proceeds in three parts. Part I summarizes the King Pharmaceuticals opinion. Part II argues that the opinion was correctly decided, and it offers an original thesis about the role that the printed matter doctrine should play to enforce patentees? disclosure obligations and preserve the deep structure of the Patent Act. Assuming that King Pharmaceuticals was correctly decided, Part III addresses the necessary next step in the continuing refinement of the printed matter doctrine. The Federal Circuit must explain why claims like the claim at issue in Prometheus Laboratories v. Mayo Collaborative Services are novel.
