Resuscitating Therasense? CD Cal Court Finds Inequitable Conduct by Patentee
IP practitioners have witnessed the dearth of inequitable conduct findings in the wake of Therasense, Inc. v. Becton, Dickinson & Co., 649 F.3d 1276 (Fed. Cir. 2011). There, the Federal Circuit reiterated en banc that to establish unenforceability for inequitable conduct before the United States Patent and Trademark Office (“PTO”), a party must prove by clear and convincing evidence that (1) information material to patentability was withheld from the PTO, or material misinformation was provided to the PTO, and that such act was done (2) with the intent to deceive or mislead. A few months ago, we reported on a case that continued to signal the death knell of this formerly ubiquitous defense, and thus begging the present question: is inequitable conduct even alive anymore? Of course it is.
