Kate A. Sherlock

Kate A. Sherlock is both an IP litigator and counselor.  She concentrates her practice in complex commercial litigation and intellectual property disputes involving trademark and copyright infringement, false advertising, trade secret misappropriation, “cybersquatting,” as well as general contract and business tort disputes. She has experience litigating in federal and state court, at the Trademark Trial and Appeal Board, and before the U.S. International Trade Commission. In addition to her litigation practice, Kate manages Archer & Greiner’s trademark prosecution and inter partes practice before the U.S. Patent and Trademark Office. She regularly counsels clients on the right to use and ability to register trademarks, and advises on intellectual property-driven business transactions, such as trademark and copyright licensing and assignment agreements.  Kate also works closely with a network of foreign IP firms to advise clients on international IP issues.

During law school, Kate interned for the Honorable Joel Schneider, United States Magistrate Judge for the District of New Jersey, and completed a five month co-op with Comcast in Philadelphia, Pennsylvania.  She was a member of the Drexel Law Review and also contributed over 100 pro bono hours to the Philadelphia Volunteer Lawyers for the Arts.

Prior to attending law school, Kate worked as a Media Licensing Coordinator in the Business and Legal Affairs Department of MTV Networks where she negotiated third-party licensing agreements on behalf of MTV, VH1, and Comedy Central.  She also has extensive experience licensing music for placement in television and movies.
