Supreme Court Will Not Review Bar for Proving Inequitable Conduct

We have previously reported on the Federal Circuit’s en banc decision in Therasense, Inc. v. Becton Dickinson & Co., 649 F.3d 1276 (Fed. Cir. 2011) issued on May 25, 2011. In that decision, the Federal Circuit heightened the standard required to show that a patent holder committed inequitable conduct during the prosecution of the patent at issue. Prior to Therasense, an accused infringer asserting inequitable conduct as a defense had to show that the withheld information or false statements were material and the patent applicant intended to deceive the USPTO. Materiality and intent were analyzed on a sliding scale, where intent could be inferred if the withheld information was considered highly material.
