Nix Patterson

Nix Patterson is a national contingency-fee litigation firm headquartered in Austin, Texas, with additional offices in Texarkana, Texas, and Oklahoma City, Oklahoma. Established over four decades ago, the firm has grown from its East Texas origins to become a prominent national player known for handling complex, high-stakes plaintiff litigation across various practice areas. The firm operates on a contingency-fee basis, investing its resources to represent individuals and companies against larger corporations.

The firm's intellectual property litigation practice specializes in representing individual inventors and smaller companies seeking to recover for the infringement of their patented technologies. Their expertise spans diverse technologies, including financial services, computer systems, and medical devices. Nix Patterson is particularly recognized for its plaintiff-side representation, having secured significant recoveries for clients whose intellectual property was allegedly taken by competitors.

A cornerstone of Nix Patterson's patent litigation success is its multi-year representation of DataTreasury Corporation. The firm played a leading role in a campaign that spanned over a decade, accusing numerous banks of infringing patents related to electronic check processing and image capture. This effort included a notable $27 million jury verdict against U.S. Bank, which was subsequently enhanced to $54 million for willful infringement before the case settled for undisclosed terms. Overall, Nix Patterson reports having filed and resolved more than 50 significant patent infringement lawsuits for a total value exceeding $750 million in the last decade, including a $115 million verdict in a separate patent case for Syntrix Biosystems.

Key partners in the firm's intellectual property litigation practice include Cary Patterson, a founding partner instrumental in leading high-profile litigation, and Nelson J. Roach, who served as lead trial counsel in the DataTreasury Corporation v. U.S. Bank case. Michael Angelovich is also a partner specializing in intellectual property protection, bringing a background as a registered patent attorney with an electrical engineering focus. The firm's public profile does not prominently feature a dedicated practice focused on PTAB or IPR proceedings, with its emphasis primarily on federal court trial litigation.
