Matan Shacham defends businesses, executives, and professionals in high-stakes, complex civil litigation.

He has also litigated appeals before the California Court of Appeal, the Ninth Circuit, the First Circuit, and the Federal Circuit.
Matan’s practice extends across a wide range of subject areas. He has deep experience in the developing fields of AI law and internet law, and he has advised and defended leading AI labs and social media companies in matters involving cutting-edge issues in those fields. He has represented some of the country’s top technology companies in high-stakes privacy, consumer class-action, antitrust, and trade secret cases. He has represented executives in high-profile securities cases and other complicated business disputes. He has also defended attorneys—from international Am Law 100 firms, regional boutiques, and plaintiff-side firms—in major legal malpractice lawsuits, partnership disputes, and disqualification and sanctions disputes.
In 2021, Matan was named a Law360 Rising Star, including for his work defending Qualcomm in a month-long antitrust trial and a related consumer class-action.
Matan has an active pro bono practice, focusing on civil rights issues. He serves on the Executive Committee for the Bar Association of San Francisco’s Intellectual Property Section, and he previously served as Chair of the Civil Rights Committee for the Anti-Defamation League’s Central-Pacific Region.
Prior to joining the firm, Matan clerked for the Hon. Sandra L. Lynch of the U.S. Court of Appeals for the First Circuit. He earned his J.D., cum laude, from Harvard Law School, where he served as Executive Editor of the Harvard Law Review.
