Jason S. McManis is a partner at AZA and the head of AZA’s intellectual property group. He is a skilled trial lawyer with extensive experience representing both plaintiffs and defendants in front of the jury in courtrooms across the United States.

Mr. McManis works on high stakes technology disputes, including patent infringement and trade secrets, and his history of success includes cases involving all types of technologies, including wireless networking, financial services, digital media, data security, oilfield services, app development, and medical devices.

From his successes across a diverse array of technologies and legal issues, Mr. McManis has learned how to simplify complex and often highly technical issues for judges, juries, and clients. IAM Patent 1000 emphasizes that “he easily resonates with a jury through distilling down complex technical details and understands the finer details of patent law to steer a case in his favour.”

Over the course of his career, Mr. McManis has taken on some of the largest companies in the world, helping to secure some of the largest plaintiff’s jury verdicts in the country in recent years, including a $78.5 million patent infringement verdict against Samsung in September 2025, over $1 billion in patent infringement verdicts against Apple, a $62.65 million verdict against United Healthcare, and a nearly $9 million verdict for a client protecting its trade secrets. Many of these verdicts have been recognized in the Texas Lawyer Verdicts Hall of Fame and among the Top 100 verdicts in the country by VerdictSearch and the National Law Journal.

In addition to his patent and trade secret work, Mr. McManis handles complex commercial disputes across the oil and gas, healthcare, commercial and residential real estate, automotive, and aviation industries. He also represents plaintiffs and defendants in catastrophic personal injury and wrongful death cases.

Numerous independent publications have recognized Mr. McManis for his trial and intellectual property success, including Law360, Lawdragon, Best Lawyers in America, IAM Patent 1000, and Thomson Reuters Super Lawyers.
