Brian Dunne is a trial lawyer specializing in complex, cutting-edge cases on behalf of plaintiffs. Brian currently represents individuals, companies, and nationwide classes in a number of large and high-profile matters.

Brian was cofounder of a litigation boutique that recouped tens of millions of dollars for clients, and appeared on Law360’s Top 5 list of plaintiff-side patent firms for the years 2015 and 2016. Brian has been lead or co-lead counsel in more than five dozen patent cases over the course of a decade, and has unique expertise in maximizing the value of multi-patent portfolios by developing and executing nationwide litigation and licensing strategies.


Brian has represented putative and certified classes in state and federal courts throughout the United States, asserting a wide range of legal claims. Brian has litigated class actions involving, among other statutes, the Sherman and Clayton Acts, RICO, the Telephone Consumer Protection Act of 1991, the California Unfair Competition Law, and the California CARD Act.

Before starting his own firm, Brian worked as an associate at Quinn Emanuel Urquhart & Sullivan LLP, where he worked on the so-called smartphone patent wars against Apple in multiple United States District Courts and the International Trade Commission (and was part of multiple trial teams), 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. Over the course of his career, Brian has briefed and/or argued cases in California, Texas, Florida, Illinois, Wisconsin, New York, Washington, Indiana, Delaware, Virginia, the District of Columbia, the International Trade Commission, and the United States Courts of Appeals for the Fifth, Ninth, and Federal Circuits.

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


Brian graduated in the top five percent of his class, Order of the Coif, at the University of Chicago Law School, where he was a member of the University of Chicago Law Review; won the Joseph Henry Beale Prize for excellence in legal writing; received a John M. Olin Fellowship in Law, Economics, and Policy; and wrote published articles on federal court standing and the competitive effects of API copyrightability.
