On July 3, 2018, the Federal Circuit issued a decision in Power Integrations, Inc. v. Fairchild Semiconductor International, Inc., et al. 2016-2691, 2017-1875 (CAFC), affirming the District Court’s findings of infringement, vacating the damages award, and remanding the case for further proceedings.
The case at issue involves Fairchild’s infringement of two patents owned by Power Integrations. The first patent, U.S. Patent No. 6,212,079 (“the ’079 patent”), covers a switching regulator which directs the transistor in a circuit when to turn on and off in order to provide the desired amount of power to an electronic device. The second patent, U.S. Patent No. 6,538,908 (“the ’908 patent”), covers a “power supply controller,” which is an integrated circuit that can perform a variety of power-regulation functions.
