Federal Circuit Significantly Tightens Doctrine of Inequitable Conduct Today in Its En Banc Therasense Ruling
By Joseph O'Malley, Bruce M. Wexler & Jason T. Christiansen
The Federal Circuit today issued its awaited en banc opinion in Therasense, Inc. v. Becton, Dickinson and Co., Appeal No. 2008-1511, defining the substantive standards for the inequitable conduct defense. As expected, the Court tightens the standards for finding both intent and materiality in order to redirect a doctrine that has been overused to the detriment of the public. Slip op. at 24.
