Richard W. Mark

Richard W. Mark is a partner in the New York office of Gibson, Dunn & Crutcher LLP, focusing his practice significantly on intellectual property and patent litigation. His tracked cases indicate a specialization in defending companies against patent infringement allegations, particularly concerning environmental technology, such as mercury emissions-control technology for coal-fired power plants. While his individual case history points to this specific technical area, Gibson Dunn's broader intellectual property practice handles complex technologies across industries including pharmaceuticals, biotechnology, telecommunications, software, and electronics.

Mark primarily serves as defense counsel, with all three of his tracked appearances on the defendant side. He notably served as lead counsel in Midwest Energy Emissions Corp. et al. v. CERT Operations II LLC et al., a case in which a federal jury ultimately awarded a $57 million patent infringement verdict in favor of Midwest Energy Emissions Corp.. However, he achieved a significant defense victory in ePlus, Inc. v. Lawson Software, Inc., where he successfully represented the defendant at trial and on appeal, leading to the vacating of a patent infringement injunction and dismissal of the case by the Federal Circuit.

Before joining Gibson Dunn, Mark was a partner at Orrick, Herrington & Sutcliffe LLP, where he led the firm's Litigation Practice Group. While Gibson Dunn's patent litigation group appears before administrative bodies including the U.S. Patent and Trademark Office (USPTO), specific details regarding Richard Mark's regular involvement in PTAB or IPR proceedings are not explicitly detailed in his public professional profiles.

Mark earned his Juris Doctor from Columbia Law School in 1980, where he was a Harlan Fiske Stone Scholar, and graduated magna cum laude from Dartmouth College in 1977. He commenced his legal career with a clerkship for the Honorable Thomas P. Griesa of the United States District Court for the Southern District of New York and is admitted to practice in New York.
