Chambers USA Recognizes Heim, Payne & Chorush Among Best Intellectual Property Litigation Firms

Elite legal guide also honors firm co-founders Mike Heim, Leslie Payne among best in Texas

HOUSTON – Houston-based intellectual property boutique Heim, Payne & Chorush has again been selected among the top intellectual property law firms in the U.S. by Chambers USA, with firm co-founders Mike Heim and Leslie Payne earning individual honors for their patent litigation work.

With a rigorous research and selection process based on unprompted client feedback and in-depth knowledge of the legal market, Chambers USA is considered one of the most prestigious rankings of business lawyers and law firms.

The firm’s patent litigation lawyers are described in the 2019 edition of Chambers USA as “easy to work with, excellent in their focus and brilliant in their judgment,” effective at both “high-level strategy and at handling the details in the weeds.”

Chambers researchers described Mr. Heim as a “hugely experienced litigator with a fine track record in patent infringement cases pertaining to the technology sector. … He is particularly noted for his representation of plaintiff-side clients and is described by interviewees as a ‘fantastic’ practitioner.”

In including Mr. Payne in the Chambers rankings for the first time, the publication described him as “a very smart lawyer” and noted “impressive market approval for his handling of complex patent infringement litigation, including recent cases relating to the oil and gas, telecom and technology sectors.”

Together and individually, Mr. Heim and Mr. Payne have led litigation teams involving complex patent disputes that have produced record verdicts and settlements. Both men have active appellate practices before the U.S. Court of Appeals for the Federal Circuit and have earned important victories for clients – both plaintiffs and defendants – ininter partes review proceedings at the U.S. Patent and Trademark Office.

Heim, Payne & Chorush, LLP, represents plaintiffs and defendants in litigation across a broad range of technologies and business sectors. With a wide variety of technical and scientific backgrounds, firm attorneys handle all facets of intellectual property litigation for some of the largest energy and technology firms, as well as individuals and smaller companies.
