Early in his career, Brian was as an associate at Quinn Emanuel Urquhart & Sullivan LLP, where he worked on the so-called smartphone patent wars, litigating (including successfully at trial) against Apple in multiple United States District Courts and in the International Trade Commission. Additionally, Mr. Dunne was lead associate in the Yahoo! v. Facebook patent case in the Northern District of California, and represented both plaintiffs and defendants in copyright, trade secret, and RMBS litigation.


Throughout his career, Brian has been praised for his ability to distill complicated, cutting-edge concepts into clear, accessible arguments. Brian has briefed and/or argued cases in California, Texas, Florida, Illinois, Wisconsin, New York, Washington, Indiana, Delaware, Virginia, Missouri, and the District of Columbia; in the International Trade Commission; and in the United States Courts of Appeals for the Fifth, Ninth, and Federal Circuits.

Before entering private practice, Brian clerked for the Hon. Jay S. Bybee of the United States Court of Appeals for the Ninth Circuit and for Hon. Susan Phillips Read of the New York State Court of Appeals.
