We thrive on high-stakes, complex litigation and enjoy being in the courtroom. Our cases frequently involve tens or hundreds of millions of dollars at stake for the parties involved. NPR often litigates against major corporations represented by the leading defense firms in the world. Individuals and companies frequently come to us when their intellectual property rights are being infringed by others and need to be enforced vigorously to ensure that justice is done.

Nix, Patterson & Roach has the experience, expertise, and resources to handle complex intellectual property litigation anywhere in the country and to level the playing field for our clients. Our clients are technological innovators and so are we. We embrace high technology in every facet of our practice and employ the latest technology at trial.

The Firm's home offices in Daingerfield and Texarkana are in the heart of the Eastern District of Texas. The Eastern District is the leading venue in the country for patent infringement litigation. The Firm’s trial attorneys have tried numerous jury trials in the Eastern District and three of our attorneys served as federal law clerks for Eastern District Judges Schell, Ward and Steeger (deceased).

In order to better serve our clients from across the country, NPR also has state-of-the-art offices in Dallas and Austin.

We are among a handful of law firms who will enforce plaintiffs’ intellectual property rights on a contingent fee basis, which enables plaintiffs to enforce their intellectual property rights against major corporations when they otherwise could not afford to and ensures that our compensation is based solely on results achieved. When justice must be done, it’s the results that matter.
