Brett Mangrum brings over two decades of intellectual property experience derived from all sides of the table. As a named inventor on eight U.S. patents—several of which he personally drafted—Brett combines technical expertise with legal acumen. While attending law school at night, he worked full-time as an engineer developing advanced nanoelectromechanical systems. Graduating in the top 10% of his class, Brett served as a law review editor, published twice, and transitioned from his engineering career to join a respected national law firm, focusing on patent prosecution and litigation.

In 2012, Brett transitioned to an in-house position as senior vice president. His in-house responsibilities included overseeing the monetization of the company’s extensive patent portfolio. This involved managing a team of in-house and external experts and working closely with external counsel on licensing and litigation efforts. While working in this complex role, Brett was named by D CEO Magazine as A Top Corporate Lawyer in Dallas-Fort Worth.

Dovetailing his diverse engineering and legal experiences together, Brett opened up a private legal practice in 2015 that he continued to grow for nearly a decade based largely on client referrals.

Brett’s present practice focuses primarily on helping clients to develop and monetize patent portfolios (including through litigation when necessary) and to defend the validity of their issued patents in post-grant review matters. In 2022, Brett was ranked first nationally (by Patexia.com) as the most active inter-parties review (IPR) attorney and, notwithstanding that volume, he also ranked eighth nationally that same year in achieving successful outcomes for patent owners. Brett’s extensive background enables him to efficiently recognize and master the complex technological and legal issues that matter most to a case.
