In a high stakes patent litigation, the future of a company may lie in the balance.  Clients rely on us to secure preliminary injunctions, declaratory and summary judgments, favorable results in Markman proceedings, advantageous settlements and appellate relief. We routinely work with clients to take cases from pre-suit investigations through discovery proceedings and trials. Our attorneys provide counsel on infringement, validity and patentability issues, and when necessary, litigate patents in federal district courts throughout the country. We also have substantial experience before the Federal Circuit, the International Trade Commission, the Patent Trial and Appeal Board, and the U.S. Court of Federal Claims.
