Deron R. Dacus

Deron R. Dacus — Patent Litigation Practice Summary

Specialty / focus areas. Dacus is an East Texas trial lawyer whose patent practice centers on district-court litigation, overwhelmingly in the Eastern District of Texas (Tyler, Marshall, Texarkana, Sherman) and increasingly Waco (W.D. Tex.). His tracked docket is concentrated in software and computer-architecture patents — communications/telecom (Portus Singapore v. AT&T/Wyze, Lemko v. AT&T, Qomplx v. Palo Alto Networks), streaming/display and user-interface software (Headwater Research v. Apple/Verizon/Charter, Express Mobile v. Oracle, Alpha Modus v. Meijer), semiconductor/memory (Advanced Memory v. SK Hynix, Radiant Patents v. Nokia) — with occasional hardware/mechanical and other technologies (Rare Breed Triggers, Orthosie GPS). His firm describes a broader trial practice spanning patent, oil & gas, and commercial litigation, and Dacus reports having appeared in well over 1,000 E.D. Tex. patent cases.

Side preference. The tracked appearances skew heavily defendant-side — 36 of 48 — with Dacus most often serving as Texas local counsel for operating companies (Apple, AT&T, Verizon, Dell, Intel, Nokia, Oracle, SK Hynix, T-Mobile, Charter, Palo Alto, Resideo, Meijer). Roughly 25% of his appearances are plaintiff-side, largely for NPE/PAE entities (Headwater, Portus Singapore, Wapp Tech, Express Mobile, Alpha Modus) and in a few lead-counsel roles, so he works both sides but is principally a defense-side E.D. Tex. local/trial counsel.

Firm context. Dacus founded The Dacus Firm, P.C. in Tyler (firm materials say "attorneys in East Texas since 1997"; earlier iterations appear in filings as "The Dacus Law Firm"). Before founding it he was with Ramey & Flock, P.C. in Tyler, and earlier with a large national firm in Dallas; he was a CPA at Price Waterhouse before law school. One tracked appearance lists him under Mann │ Tindel │ Thompson, but that affiliation is not otherwise web-verifiable.

Notable cases and outcomes. Most prominent reported result: complete defense verdict for CNEX Labs in Huawei v. CNEX Labs (E.D. Tex. 2019), a nationally covered trade-secret case in which Dacus was trial counsel against ~$86M in claims. He also co-counseled Nokia's April 2024 non-infringement defense verdict in Marshall, and firm announcements credit him as lead trial attorney in a $39M Lowrance patent verdict, an $8.2M Genband infringement verdict, and multiple Genband defense verdicts (patents invalid / no infringement) against Metaswitch — the firm's own descriptions, not independently verified here. On the plaintiff side, he was Ravgen counsel in the $272.5M Ravgen v. Labcorp verdict (W.D. Tex. 2022).

PTAB / IPR experience. Dacus is primarily a district-court advocate, but his files regularly intersect with IPR/PGR practice — e.g., notices of PTAB institution filed in his E.D. Tex. cases (Radiant v. Nokia IPRs; Ravgen IPRs), and appearances in IPR2014-01357 and PGR2020-00049 records. The evidence shows coordination with PTAB proceedings rather than a standalone IPR-heavy practice.

Bar / education. Texas Bar 1994 (also admitted in Wyoming, 2016); J.D., Baylor Law School (cum laude, 1994); B.B.A., Texas A&M (cum laude, 1989); Board Certified in Civil Trial Law (Texas Board of Legal Specialization) and licensed CPA.
