Litigation and Arbitration

Intellectual Property Litigation

Our intellectual property litigation and arbitration practice has lead clients to successful victories in a number of landmark cases in the field. Intellectual property disputes may be fought in multiple jurisdictions, and our global expertise gives us particular insight into international litigation and arbitration. We tailor our strategies based on our clients’ needs, and give practical advice with respect to asserting, defending against, or settling intellectual property claims.

The firm’s vibrant practice in this area includes litigation and arbitration of trademark, trade dress, patent, copyright, and trade secret disputes in a variety of settings, both traditional (e.g., copyright and trademark infringement claims against television commercials for toothpaste) and unusual (e.g., representing the family of the lawyer depicted in the film “Philadelphia” in an action against the movie studio for unauthorized exploitation of his life story). We have particular experience and expertise in international patent and trademark infringement matters, including counseling foreign patent and trademark owners in establishing intellectual property enforcement programs and enforcing their rights against infringers in U.S. courts.
