Unlike IP boutique firms, Calfee’s Trademark practice is an important part of a leading general corporate and litigation firm. Our attorneys provide full-service representation in all aspects of trademark law, including domestic and foreign trademark registration, strategic portfolio management and enforcement, oppositions and cancellations, licensing and litigation of trademark, trade dress, domain name and unfair competition claims such as false advertising.

We have provided trademark portfolio and enforcement support services for more than 20 years and have nearly 13,000 active trademark matters for clients under our care.

We counsel both private and public companies in a variety of industries on trademark and unfair competition matters such as false advertising.

For clients with trademark rights outside the United States, our attorneys work with and through an extensive network of foreign associates that covers virtually every jurisdiction around the world in which trademark rights are recognized.

On the portfolio management side, each of our trademark clients is assigned its own trademark administration team. Our full-time docket staff and sophisticated IP docketing system help us ensure responsiveness to our clients and maintain quality and accuracy of our work.

Our vast experience in counseling on and prosecuting thousands of trademark matters for clients around the world allows us to devise cost-effective strategies to maximize prosecution success. It has been our experience that many routine “informalities” raised in office actions can be avoided by careful preparation in the early stages of the selection and prosecution process.

While litigation is rarely desirable to our clients, the business and dispute resolution experience of our intellectual property lawyers is invaluable as it enables our attorneys to anticipate and help avoid potential portfolio development and management disputes. It also can optimize a client’s position if litigation becomes unavoidable, because we understand the importance of monitoring how marks are used, the importance of careful searching techniques and protocols, and the need for systematic and continuous documentation efforts with respect to the use of marks.
