Widely recognized as a preeminent scholar of intellectual property law, Mark A. Lemley (BA '88) is an accomplished litigator—having litigated cases before the U.S. Supreme Court, the California Supreme Court, and federal circuit courts—as well as a prolific writer with more than 100 published articles and six books. He has testified numerous times before Congress, the California legislature, the Federal Trade Commission, and the Antitrust Modernization Commission on patent, trade secret, antitrust, and constitutional law matters. He is also a partner and founder in the firm Durie Tangri LLP. His contributions to legal scholarship focus on how the economics and technology of the Internet affect patent law, copyright law, and trademark law; and at Stanford he currently acts as the director of the Program in Law, Science & Technology, and the director of the LLM Program in Law, Science & Technology.
Before joining the Stanford Law School faculty in 2004, he was a professor of law at the UC Berkeley School of Law (Boalt Hall) and at the University of Texas School of Law. He also served as counsel at Fish & Richardson and Brown & Bain as well as clerked for Judge Dorothy W. Nelson of the U.S. Court of Appeals for the Ninth Circuit.
