Doug Winthrop, co-chair of the firm’s Intellectual Property practice group and a former United States Supreme Court law clerk, focuses his litigation practice on intellectual property and unfair competition, business torts, claims of breach of fiduciary duty, contract disputes, and class action defense at both the trial court and appellate levels.
Doug has represented numerous technology, manufacturing, consumer products and financial services companies in matters raising claims of trade secret misappropriation, breach of fiduciary duty, misrepresentation, breach of the implied covenant of good faith and fair dealing, and breach of contract, as well as in consumer class actions and copyright and trademark suits. He recently defended an international manufacturer against parallel federal and state litigation asserting trade secret misappropriation and trademark infringement, and previously defended trade secret misappropriation claims against one of the world's largest semiconductor manufacturers, resulting in a dismissal of claims and an award of fees against the plaintiff. He also has extensive experience in complex commercial litigation. Since 2007, he has represented a U.S. mortgage insurance company in multimillion-dollar rescission litigation as well as the successful trial defense of claims challenging mortgage insurance benefit curtailments. Doug successfully represented Quicken Loans, at both the trial court and on appeal, in the defense of a class action suit claiming violation of California law relating to interest payments on property insurance proceeds.
Doug was honored with the Artistic Freedom Award by the ACLU of Southern California for his and his colleagues' successful representation of artist Thomas Forsythe against claims of trademark and copyright infringement brought by Mattel Inc. (Mattel Inc. v. Walking Mountain Prods., 353 F.3d 792 (9th Cir. 2003)).
Doug served as law clerk to Associate Justice John Paul Stevens of the United States Supreme Court, 1992–1993, and to Judge Patricia M. Wald of the United States Court of Appeals for the District of Columbia Circuit, 1991-1992.
Doug graduated magna cum laude from the University of Minnesota Law School, where he was an Editor of the Minnesota Law Review and was awarded the Order of the Coif.
