Rex Mann

Rex Mann is a trial lawyer who focuses his practice on patent litigation and other complex commercial litigation matters. Although his patent litigation practice is nationwide, he has extensive experience specifically in patent-heavy districts, including the Eastern and Western Districts of Texas. On commercial matters he often represents technology companies or works on matters involving complex technology, and his background in engineering enables him to deeply understand clients’ technologies and businesses to help them better achieve their goals. Rex’s work continues to garner him honors from legal publications such as The Best Lawyers in America®, IAM Patent 1000, Lawdragon, and Benchmark Litigation.

Rex’s intellectual property practice primarily consists of complex patent and trade secret litigation. He has handled bet-the-company patent and trade secret matters, including taking them to trial, and winning. Outside of litigation, he advises his clients on technology licensing issues, policies relating to intellectual property, and targeted patent prosecution advice relating to licensing and litigation.

“Rex’s patent litigation practice is heavily concentrated on matters arising in the Eastern and Western Districts of Texas. In fact, he began his legal career as a law clerk for the Honorable T. John Ward in the Eastern District of Texas, where he gained significant experience in federal trial practice and patent litigation, given the district’s intense patent trial docket.

Rex has significant trial experience and has tried more than 20 cases or arbitrations as first chair or in an otherwise stand-up role, and he has experience in all phases of trial. In addition to his civil trial work, Rex spent three months on loan as an assistant district attorney in Dallas County, where he tried numerous criminal jury trials to verdict and obtained a guilty verdict in each one.

Rex’s commercial litigation practice has included a wide variety of matters, including breach of contract, business torts, consumer class actions, RICO violations, securities laws violations, whistleblower or False Claims Act litigation, employment, fraud, suits against the government or government officials, and other related disputes. Given his background in engineering, the work Rex does for his commercial clients often involves technology issues. Moreover, his undergraduate and graduate degrees in civil and environmental engineering are helpful when working on matters in the environmental and oil and gas industries.
