Nick Guinn is a registered patent attorney specializing in all aspects of intellectual property, with an emphasis on litigation, primarily patent, trademark and copyright infringement actions. His practice also includes counseling clients in the areas of unfair competition, trade secrets, and licensing matters. Nick also prosecutes patent and trademark applications and handles various trademark proceedings before the U.S. Trademark Trial and Appeal Board of the U.S. Patent and Trademark Office.

Prior to joining the firm, Nick served as a law clerk to Chief United States District Judge Fred Biery of the United States District Court for the Western District of Texas. In this role, he drafted orders for the Court and assisted with preparing jury charges. Through this experience, he developed tremendous insight into the procedures and considerations of the Court.

During law school, Nick completed an internship with Justice Steven Hilbig at the Texas Fourth Court of Appeals, served as president of the St. Mary's University Student Bar Association, and Vice Chair of the ABA Law Student Division. Prior to law school, Nick studied chemical engineering at the University of Texas and aided in separations research. He is a frequent speaker on intellectual property and litigation issues, including discovery and evidentiary matters relating to social media, and is frequently invited to give presentations at various organizations.

In addition to his practice, Nick immerses himself in the community. He enjoys volunteering with KLRN and Christian Assistance Ministries. He is an active member of his church—teaching Sunday school, coaching high school basketball, and corresponding with missionaries across the world.

Nick is admitted to practice before the Supreme Court of the State of Texas, the U.S. District Court for the Western District of Texas, the United States Court of Appeals for the Fifth Circuit, and the United States Patent and Trademark Office.

Personal Interests

An avid fan of "the sports," Nick enjoys basketball and the San Antonio Spurs. If he's not on the hardwood shooting mid-range jumpers, he loves to swim, bike and run in preparation for his next triathlon. Although debated in most tri circles, Nick is of the school of thought that a fourth and equally important component of triathlons exists: nutrition. In addition to working and exercising, Nick loves spending time with his family and friends—especially, the love of his life, Kristen "Soon to be Guinn" Carroll.
