Deron D. Dacus — patent litigation summary

Specialty / technical focus. Dacus is an East Texas–based trial lawyer whose practice centers on patent and complex commercial litigation, with a stated emphasis on the Eastern District of Texas (Tyler, Marshall, Texarkana, Lufkin) and the district's local patent rules. His docket reflects a broad technology mix rather than a single niche: telecommunications and VoIP/networking (GENBAND/Metaswitch, VOIP-PAL v. Verizon, Comcast, AT&T), RF/semiconductor and downconversion circuitry (ParkerVision; CNEX Labs' SSD memory-controller technology), wireless and consumer electronics (Qualcomm; Dell; Supercell), network security software (the Webroot/OTI v. AO Kaspersky matter), molecular diagnostics (Ravgen v. Quest Diagnostics), and marine electronics/sonar (Navico/Lowrance v. Garmin). Firm materials also list oil-and-gas and general business/commercial litigation as core areas.

Side preference. He works both sides rather than occupying a fixed plaintiff or defense posture, consistent with his tracked appearances (one plaintiff-side, one defendant-side, both as lead counsel). Public dockets show him repeatedly retained as local/regional trial counsel for large operating companies defending infringement claims — Qualcomm, Verizon entities, Nokia, Dell, Comcast, AT&T, and others — while his best-publicized plaintiff-side work has been for patent owners and technology licensors such as Navico/Lowrance, EON Corp., GENBAND, Ravgen, and ParkerVision. He is not identifiable as an NPE/PAE-focused filer; the representation mix is closer to a defense-oriented local-counsel practice supplemented by contingency plaintiff patent cases.

Firm context. He practices at The Dacus Firm, P.C. (also referred to in some records as The Dacus Law Firm), Tyler, Texas, which his profile describes as operating in East Texas since the late 1990s. He is not in-house. Before returning to East Texas, he practiced at a large national firm in Dallas, and prior to law school he was a senior accountant at Price Waterhouse.

Notable matters and outcomes. Reported results include a $39 million willful-infringement verdict for Navico/Lowrance against Garmin in 2017 (Marshall Division, down-scan sonar imaging), an $18.8 million verdict for EON Corp., an $8.2 million infringement verdict for GENBAND, and defense wins for GENBAND in a follow-on Metaswitch case (jury found no infringement and the asserted patents invalid). He was part of the trial team that obtained a complete defense victory for CNEX Labs in Huawei Technologies Co. v. CNEX Labs, Inc. (E.D. Tex.), where the jury rejected Huawei's trade-secret and related claims. The tracked ParkerVision, Inc. v. NXP Semiconductors N.V. matter (W.D. Tex. 6:23-cv-00389) appears on the plaintiff side; note that public reporting on the ParkerVision litigation identifies other lead firms, so his precise role there is not independently confirmed by the sources reviewed.

PTAB / IPR exposure. His PTAB footprint appears to be supporting rather than lead: he shows up as counsel of record/attorney to be noticed in several PTAB filings and, more prominently, in district-court stipulations coordinating invalidity defenses with parallel IPR petitions (e.g., the 2024 Comcast IPRs, and IPR2020-01129 in the Verizon matter). I did not find evidence that he is a routine lead petitioner-side IPR advocate.

Bar / education. Licensed in Texas (1994); J.D., cum laude, Baylor University School of Law (1994); B.B.A., cum laude, Texas A&M University (1989). Board Certified in Civil Trial Law (Texas Board of Legal Specialization) and a licensed CPA. Verified sources render his name as Deron R. Dacus (Texas Bar No. 00790553) of The Dacus Firm, P.C., Tyler, TX — likely the same attorney as the "Deron D. Dacus" in the tracked data, though the middle-initial discrepancy is worth confirming. Firm-website claims regarding the volume of his patent docket and verdict totals are self-reported and not independently verified here.
