Michael P. Lehmann

Michael Lehmann is a Senior Partner at Hausfeld’s San Francisco office. He obtained his undergraduate degree from the University of California at Berkeley in 1974 and his J.D. from Hastings College of the Law in 1977.

In 1978, he joined the Furth, Fahrner & Mason law firm and began practicing antitrust and business litigation. He was at that firm until 2007; it was the Furth & Lehmann firm when he left, with him having achieved the title of Managing Partner. During the first part of his career at the Furth firm, he did extensive defense work for a varied roster of clients, such as the Santa Fe Southern Pacific Railway Co., Sprint Communications Co., Kellogg Co., Grolier Inc., News Inc., Columbia Pictures, Georgia-Pacific Co., and William Sullivan (former owner of the New England Patriots). He was among those representing these entities as either defendants in class action antitrust litigation, plaintiffs in individual antitrust cases, defendants in proceedings brought by the Federal Trade Commission, petitioners in proceedings before the United States Food and Drug Administration, or respondents in arbitration proceedings before the International Chamber of Commerce. During this phase of his career, Mr. Lehmann helped Kellogg defeat a charge by the FTC that it and other ready-to-eat cereal companies engaged in a “shared monopoly” and wrote submissions to the FDA that caused it to permit certain types of health claims on food labels.

While at Furth, Mr. Lehmann played significant roles (including several co-lead positions) on the plaintiffs’ side in major antitrust class actions, such as the Brand Name Prescription Drug Antitrust Litigation, the Dynamic Random Access Memory (DRAM) Antitrust Litigation, the Static Random Access Memory (SRAM) Antitrust Litigation, the Cathode Ray Tube (CRT) Antitrust Litigation, the TFT-LCD (Flat Panel) Antitrust Litigation, the Cosmetics Antitrust Litigation, the Graphics Processing Units (GPU) Antitrust Litigation, the Compact Disc Minimum Advertised Price Antitrust Litigation, the Publication Paper Antitrust Litigation, the High Pressure Laminates Antitrust Litigation, the Bristol Bay Salmon Fishery Antitrust Litigation, and the Intel Microprocessor Antitrust Litigation.

In 2007, Mr. Lehmann left the Furth firm to set up the San Francisco office of Cohen Milstein, Hausfeld & Toll, where he was a partner. When the separate Hausfeld firm was created in November of 2008, he left Cohen Milstein and joined Hausfeld as one of the founding partners and has worked there ever since. Among the cases he has worked on since joining Hausfeld (in addition to some of those already mentioned) are: the Packaged Seafood Products Antitrust Litigation, the Inductors Antitrust Litigation, the Disposable Contact Lens Antitrust Litigation, the Aftermarket Automotive Lighting Products Antitrust Litigation, the Municipal Derivatives Antitrust Litigation, the Transpacific Air Passenger Transportation Antitrust Litigation, the International Air Transportation Surcharge Antitrust Litigation, the Domestic Airlines Antitrust Litigation, the Blue Cross & Blue Shield Antitrust Litigation, the NCAA Student-Athlete Name & Licensing Litigation, the Optical Disk Drive Antitrust Litigation, the Fresh & Process Potatoes Antitrust Litigation, the Rail Freight Fuel Surcharge Antitrust Litigation, the Generic Drugs Antitrust Litigation, the Diisocyanates Antitrust Litigation, and the Chicago Board Options Exchange Volatility Index Antitrust Litigation, and the In re Farm-Raised Salmon and Salmon Products Antitrust Litigation. The Hausfeld firm has sole lead, co-lead or other leadership positions in many of these cases.

Mr. Lehmann has written or co-written numerous articles on antitrust and legal matters. He has been recognized either generally or in the antitrust field in the publications Best Lawyers in America and San Francisco’s Best Lawyers, as a Northern California Super Lawyer and is the recipient of a Martindale-Hubbell Judicial AV Preeminent rating.
