The experienced trial lawyers at Heim, Payne & Chorush LLP focus on technologically complex patent infringement, trade secrets and patent-related class-action antitrust litigation. These cases involve a variety of proprietary and nonproprietary technologies including microprocessors, wireless local area networks, oilfield technology, computer architecture and much more. The firm represents plaintiffs and defendants across the country in state, federal and appellate courts, including the Federal Circuit Court of Appeals and the United States Supreme Court. Its clients range from some of the largest energy and technology firms in the world to small startups.

Heim, Payne & Chorush attorneys come from a wide variety of technical backgrounds in engineering and science. Each has one or more degrees in electrical engineering, computer engineering, chemical engineering, material engineering, physics, or chemistry. Many served clerkships at the United States Court of Appeals for the Federal Circuit and/or the United States District Court for the Eastern District of Texas. Many are registered to practice before the United States Patent & Trademark Office. One received the highest score on the Texas Bar Examination, and another is a former U.S. patent examiner.

Heim, Payne & Chorush lawyers have earned some of the largest patent infringement verdicts and settlements in the country, while the firm’s patent-related antitrust work has resulted in record outcomes against pharmaceutical companies that abuse patent laws to gain an unfair competitive advantage. With the rise of post-grant challenges at the U.S. Patent Trial and Appeal Board, Heim, Payne & Chorush has an active practice in inter partes review proceedings and has successfully represented both patent owners and petitioners in IPR proceedings.

The firm’s unique combination of technical knowledge and top-tier legal experience and credentials allows it to achieve the best possible results for its clients as it handles all facets of the most complicated intellectual property litigation.
