ABOUT Carlos Ruiz

Carlos Ruiz's practice focuses on patent litigation and antitrust cases. He takes an analytical approach to litigation informed by his scientific background and research experience. Carlos earned his law degree from the University of Houston Law Center, where he served as senior articles editor for the Houston Journal of Health Law & Policy and was active in national and international moot court and arbitration competitions, including earning a Best Speaker and First Finalist awards. 

Before becoming a lawyer, Carlos earned an undergraduate degree in biochemistry and co-authored journal publications on neuroscience and pharmacology research at the Waggoner Center for Alcohol & Addiction Research at the University of Texas at Austin. This experience exposed him to the painstaking processes required in scientific research and innovation. 

Carlos leverages that background to represent businesses and inventors in patent litigation related to a wide range of technology and business sectors, including oilfield technology, biotechnology and the wireless industry. He is able to analyze and understand technology at the heart of patent disputes and effectively communicate those concepts and key points to judges and juries. In addition to his patent infringement caseload, Carlos also handles patent-related antitrust litigation against pharmaceutical companies that abuse patent laws to gain an unfair competitive advantage.
