Infringement Litigation

Much of the firm’s practice involves patent, trademark, and copyright infringement litigation, as well as trade secret and unfair competition litigation. In patent infringement cases, the successful presentation of a client’s case requires that the lawyers understand the technology involved. While some technical areas are less complex, frequently our attorney must bring their substantial technical experience to bear on the case in order to translate the subject matter into a form understandable by a technically unsophisticated judge or jury. In litigation, sometimes it is not enough to win the battle at trial. Our attorneys have successfully argued several Federal Circuit appeals. The firm also appears before regional appeals courts.

Other Intellectual Property Litigation

Our litigation practice also includes state law litigation over trade secrets, false advertising and other unfair competition and business practices as well as contested administrative proceedings before the Patent Office Board of Patent Appeals and Interferences and the Trademark Trial and Appeal Board.

International Litigation

The firm has a worldwide clientele. We represented not only North American companies, but also European, Japanese, and multinational companies. We have found that for many clients, a U.S. patent litigation is often only one aspect of a more global dispute. We have coordinated such multinational disputes in a number of cases, both to ensure that the U.S. litigation, which is our primary responsibility, is not compromised by event in other countries and to assist counsel in those countries to present the most effective claims and defenses.
