How to Meet the Inequitable Conduct Standard after Therasense

The Court of Appeals for the Federal Circuit recently clarified the standard necessary for holding a patent unenforceable for inequitable conduct relating to intentionally withheld references and misrepresentations of material information. Apotex Inc. v. UCB, Inc., No. 2013-1674 (Aug. 15, 2014). Given the high standard set forth in the Federal Circuit’s prior opinion in Therasense, this decision finding inequitable conduct provides a roadmap for inventors, prosecutors, and litigants alike with regard to potential claims of inequitable conduct.
