Senior Counsel
Antitrust & Competition

Laurence Popofsky, a senior counsel in Orrick’s San Francisco office, is a member of the Litigation Group. Mr. Popofsky focuses his practice on a variety of antitrust and intellectual property matters, encompassing all aspects of antitrust jurisprudence, both state and federal court and agency alike.

Mr. Popofsky has argued two cases in the U.S. Supreme Court and achieved a landmark victory in Continental T.V., Inc., et al. v. GTE Sylvania Inc.  He has also argued more than 60 appeals, the majority of which involved antitrust issues. More recently, he led the litigation teams representing Visa U.S.A. in antitrust litigation involving Dean Witter, Discover and American Express, and served as appellate counsel in LePage’s v. 3M, McKenzie v. PeaceHealth, and Masimo v. Tyco bundling pricing cases.

Mr. Popofsky lectures extensively on antitrust and related issues, including, most recently, at the Sedona Antitrust Conference in 2006-2007. He co-chaired the Advanced Antitrust Course on several occasions and is currently on the Antitrust Advisory Committee of the Practising Law Institute. He has written numerous articles in the field of antitrust and has served on the Trade Regulation Advisory Board of the Bureau of National Affairs for more than 30 years. He was recently invited to testify before the Department of Justice’s Antitrust Modernization Commission and the DOJ-FTC Merger Guidelines Workshop. He was invited to lecture at Oxford University’s Center of Competition Law & Policy in 2013 on the subject of vertical restraints and resale price maintenance under American law, and in 2014 on opt-out antitrust class actions.

Before joining Orrick, Mr. Popofsky was at Heller Ehrman LLP and served as firm chairman from 1985 to 1992.
