T. Deron Dacus

T. Deron Dacus is a trial attorney and founder of The Dacus Firm in Tyler, Texas, with a practice focused on patent, business, and commercial litigation. He has extensive experience in the U.S. District Court for the Eastern District of Texas, having represented clients in over 1,000 patent cases. His work covers a range of technologies, including telecommunications, medical diagnostics, and software. Prior to founding his firm, Mr. Dacus worked at a large national law firm in Dallas and is also a licensed Certified Public Accountant.

The single tracked case shows Mr. Dacus representing a defendant as local counsel in Rare Breed Triggers Inc et al. v. Thomas Carter II et al. However, his broader practice involves representing both plaintiffs and defendants in high-stakes litigation. His firm's news reports and biography highlight a balanced practice, securing multi-million dollar verdicts for patent owners and successfully defending companies accused of infringement. This includes obtaining a $272.5 million plaintiff-side verdict for Ravgen against Labcorp and securing a complete defense verdict for AT&T against Daingean Technologies.

Mr. Dacus has served as lead trial counsel in several other notable cases, including securing a significant trade secret victory for CNEX Laboratories against Huawei. His practice appears to be concentrated on district court litigation, and public records do not indicate regular appearances as counsel in IPR or other PTAB proceedings. A 2021 Managing IP article identified him as one of the most active local counsel for defendants in the Eastern District of Texas.

Mr. Dacus earned his J.D. cum laude from Baylor University School of Law and a B.B.A. cum laude from Texas A&M University. He was admitted to the Texas bar in 1994.
