Scott’s practice encompasses patent litigation, preparation, and prosecution; trademarks; and other IP and technology matters. He has represented clients in complex patent cases related to automobile, mobile computing, telecommunications, Internet, electric motors, recommendation systems, and software-based technologies in numerous federal courts and the U.S. International Trade Commission. He also represents clients in post grant review proceedings such as inter partes review before the United States Patent & Trademark Office and provides counseling to clients on issues such as patentability search, non-infringement, and patent validity.
