Judicial Clerkships

The Honorable Reynaldo G. Garza, United States Circuit Judge for the Fifth Circuit Court of Appeals (1989-90).
Phillip B. Philbin

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 attorney 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.

Mr. Philbin has represented inventors, authors, and innovators as either plaintiff or defendant:

Heart Repair Device Patent Infringement Jury Trial
A Texas jury returned a verdict affirming the validity of Haynes and Boone, LLP client Chase Medical, Inc.’s patents covering a method for surgically repairing human hearts after a severe heart attack.  The verdict found not only infringement but that the infringement was willful. Jurors concluded that Chase Medical was due lost profits of $306,669 and royalty damages of $131,725 because the defendants marketed a device, “the Blue Egg,” which mimicked the Mannequin. The jury’s unanimous finding of willful infringement provided foundation for a request by Haynes and Boone attorneys for enhanced damages and attorneys fees.

Summary Judgment Defense Victory in Toll-Collection Technology Patent Case
Haynes and Boone established new precedent for patent exhaustion by obtaining summary judgment dismissal, with Federal Circuit affirmation, of a lawsuit alleging infringement of electronic toll collection patents in a case with broad implications for the U.S. toll collection industry. The case could have cost client Electronic Transaction Consultants Corporation (ETC) more than $60 million and had the potential to jeopardize the system that currently collects about 80 percent of all electronic tolls in the United States. The lawsuit was brought against ETC by TransCore, who alleged that ETC infringed four different TransCore patents that relate to the automatic electronic collection of tolls. TransCore sought more than $20 million in damages, which it sought to treble to $60 million. TransCore had alleged that ETC’s “use” of allegedly infringing toll-collection equipment infringed its patents. But the court held that TransCore’s earlier settlement with the equipment manufacturer had exhausted TransCore’s rights in the patents, and granted judgment to ETC.
