Russell Chorush is a co-founder of Houston-based Heim, Payne & Chorush, a patent litigation boutique that is known for its sophisticated and effective litigation related to patent infringement and patent-related antitrust work. Russ is a true pioneer in patent-related antitrust litigation against pharmaceutical companies under the Sherman Antitrust Act and FTC v. Actavis, Inc., 133 S. Ct. 2223 (2013). Russ plays leadership roles on multifirm teams and has assisted in securing groundbreaking recoveries in excess of $1 billion, prevailing in every case he has tried to final decision. With a Ph.D in chemistry, Russ is uniquely qualified to handle patent-related antitrust litigation on behalf of direct purchasers and retailers who are harmed when pharmaceutical manufacturers abuse patent laws for an unfair competitive advantage.

Prior to law school, Russ served as a laboratory manager for Texas Instruments, Inc. (TI) and Air Liquide Corporation. He is a co-author of the book “Handbook of Chemicals and Gases for the Semiconductor Industry,” as well as a number of published articles and is a named inventor on several patents assigned to TI. He is an author of six published articles in peer-reviewed journals including the Journal of the American Chemical Society, Analytical Chemistry and the Journal of Mass Spectrometry. He received his Ph.D. in analytical chemistry from Cornell University in 1994 and a B.S. in chemistry from the University of Texas at Austin in 1989.
