Dina Roumiantseva focuses her IP practice on trademark counseling, prosecution, and litigation, as well as copyright infringement, cybersquatting, trade secrets, and contract disputes.

With experience handling proceedings in federal and state courts and in arbitration, Dina counsels clients ranging from startups to established multinational brands on selecting and protecting strong trademark portfolios, managing risks associated with new product designs, trademark and copyright enforcement – including opposition and cancellation proceedings before the Trademark Trial and Appeal Board – and on intellectual property aspects of corporate transactions. Her litigation experience includes representing a leader in the hemp-based cannabidiol (CBD) industry, a leading brewing company, and one of the largest consumer genetic testing companies in trademark disputes, all of which settled with favorable outcomes.

Dina is regularly called upon by clients for her deep working knowledge of trademarks and copyrights and her innovative approach to problem solving. She is actively involved with the Publications Committee of the International Trademark Association, developing up-to-date content for practitioners and the public.

During law school, served as a judicial extern to both the Honorable Susan Y. Illston of the US District Court, Northern District of California and the Honorable Marsha S. Berzon of the US Court of Appeals, Ninth Circuit.

Dina resides in Berkeley, California. Outside of her growing IP practice, she enjoys road cycling, surfing and stand-up paddleboarding, visual arts, and mentoring Berkeley Law students.
