Brian Brookey specializes in intellectual property litigation, with expertise and success on behalf of both plaintiffs and defendants in patent, trademark, copyright, and trade secret litigation. He also frequently mediates IP disputes.

Admitted in both California and Washington, D.C., Brian has litigated cases in approximately two dozen states. He also handles matters in U.S. Courts of Appeals from coast to coast, before the International Trade Commission, and with the Trademark Trial and Appeal Board and Patent Trial and Appeal Board of the United States Patent and Trademark Office. In addition to his litigation practice, Brian also is a sought-after mediator for intellectual property disputes.

Brian represents a broad range of companies from around the United States and the world across numerous industries and technologies, including telecommunications, computer software, lasers, construction, apparel, lighting, medical devices, automotives, consumer products, musical devices, electronic components, photography accessories, and transportation services.

Brian brings client-focused, cost-effective strategies to every case. At the beginning of a litigation matter, he develops clear objectives with the client. He then works toward meeting those objectives without unnecessary and expensive tactics that don’t advance the client’s cause.

Brian is a strong advocate for increasing diversity, equity, and inclusion in the legal community at large, and within the IP field especially. Brian has written and spoken on the topic, and he holds a leadership position within the Diversity and Inclusion Committee of the Intellectual Property Owners Association. Brian is particularly proud of his role as founder and past chair of lgbTE, Tucker Ellis’s LGBTQ+ employee resource group. He is the immediate past chair of the firm’s Equity, Diversity, and Inclusion Committee, and he is co-chair of St. John’s Pride, an active community of LGBTQ+ members of the historic St. John’s Church on Lafayette Square in D.C.

When not working, Brian can usually be found traveling (or planning a trip), attending live theatre, reading Pulitzer Prize-winning literature, or watching British detective dramas. Brian also holds the dubious distinction of losing on Jeopardy! to one of that show’s all-time greatest champions.
