The qualities that distinguish the typical Williams & Connolly LLP approach to litigation are also hallmarks of the firm's representation of clients in trademark, false advertising, and unfair competition cases. An aggressive discovery and motions practice, careful selection and use of experts, and a constant focus on preparing the case for trial - these components of Williams & Connolly's approach to litigation transfer smoothly to legal conflicts involving trademarks, trade dresses, and unfair competition as defined by the Lanham Act.

The firm provides representation in a wide variety of matters in numerous industries, including motion pictures, apparel, toys, standardized test preparation, luxury goods, shopping centers, hotels, financial services, non-profit advocacy groups, and e-commerce.

In addition to prosecuting and defending contested claims, Williams & Connolly attorneys provide counseling on trademark and trade dress issues, including advice on clearance of proposed trademarks. They also prepare and prosecute trademark registration applications, and represent clients before the Trademark Trial and Appeal Board of the U.S. Patent and Trademark Office.

Williams & Connolly also has extensive experience litigating on behalf of and advising clients about unfair and deceptive advertising. The firm's lawyers have litigated numerous false advertising claims involving software products, books, the results achieved from and other features of standardized test preparation courses, as well as claims made by rental car companies and dietary supplement manufacturers.
