In 1978, far before joining Hausfeld, Michael 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. In 2007, Michael 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.
Over the past 40 years, Michael 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.
During the first part of his career at the Furth firm, Michael 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.
