About me

Jason's practice includes class action litigation, antitrust and unfair competition, and music law. He is involved in all aspects of civil litigation and has handled cases in both federal and state courts, in litigation and at trial. For the past several years, his practice has involved primarily antitrust and consumer class actions, often representing the largest plaintiff class members in nationwide antitrust actions.


Jason has successfully represented plaintiffs in federal Section 1 (conspiracy) and Section 2 (monopoly) Sherman Act cases and in state law actions alleging unfair business practices, false advertising, warranty and Proposition 65 violations, among other claims. He has served as lead counsel and in senior litigation roles in numerous class actions, which have collectively recovered billions of dollars for plaintiffs.


Jason speaks regularly at CLE seminars on class action and antitrust issues and has published a number of articles on those issues.
