Phillip Philbin is a partner, a member of the firm's board of directors, co-chair of the Intellectual Property Litigation Practice Group, and former chair in the firm's Business Litigation Section. He joined the firm in 1990 after serving as law clerk to the Hon. Reynaldo G. Garza, United States Circuit Judge for the Fifth Circuit Court of Appeals.


Mr. Philbin is a sought-after trial lawyer whose practice encompasses a wide range of intellectual property matters, including patent, trademark, trade dress, copyright, trade secret and unfair competition. His portfolio of patent litigation experience is particularly noteworthy, having successfully tried numerous cases to juries and judges across the country. His more than 20 years of trial experience on both sides of the aisle have honed his ability to leverage trial strategy to his clients' greatest advantage, and he has positioned many cases for settlement prior to trial or after appeal.

Clients value Mr. Philbin for his ability to understand complex technology, as well as his courtroom skills. As a registered patent attorney, he is fluent in both the legal framework of patent law and the technical aspects of the patents he explains, and he deftly translates highly technical concepts for judges and juries. He incorporates all aspects of a client's case - technological, business, and legal objectives - to craft a cohesive strategy that works both in and out of the courtroom. As a result of this experience, he has played an integral role in a number of notable patent cases.

In addition to his busy trial schedule and leadership roles within the firm, Mr. Philbin is a frequent author and speaker on patent topics and serves as an adjunct professor at SMU Dedman School of Law, where he teaches a patent litigation class for which he helped develop the curriculum.
