Mark Samuels counsels leading technology and other innovative companies on some of their most challenging intellectual property matters. Mark founded O’Melveny’s Intellectual Property & Technology practice group more than two decades ago and served as its Chair for several years. He focuses his practice on patent, trade secrets, copyright, trademark, and technology-intense litigation, including cases poised at the intersection of patent and antitrust law. A Vice Chair of the firm and one of its most accomplished trial lawyers, his successes include serving as lead counsel for AMD in history-making litigation against Intel Corporation, which resulted in a record-breaking US$1.25 billion payment by Intel to AMD.

Mark is consistently recognized as a leading intellectual property practitioner by Chambers USA; as one of California’s top patent litigators by the Daily Journal; as one of America’s 500 top lawyers by Lawdragon 500; and as one of the “Best Lawyers in America” by Best Lawyers. In recommending Mark, Chambers USA quotes a source describing him as “extremely responsive and client-centric as well as being a superb litigator.”
