I'll research this attorney before drafting.

E. Leon Carter — patent litigation snapshot (Dallas, TX)

Focus and side. Carter is a generalist commercial trial lawyer with a patent/IP component rather than a dedicated patent specialist. His firm bio and Best Lawyers listings (Patent Litigation; Litigation–Intellectual Property, recognized continuously from at least the 2012 through 2027 editions) describe patent, trade secret and unfair competition work, and his patent matters have clustered in the Eastern District of Texas during the "rocket docket" era. Searchable subject matter skews mechanical/optical (fiber-optic connectors) and software (video-game and healthcare-IT patents asserted by Uniloc). His tracked record is defense-side (1 defendant-side appearance, 0 plaintiff-side), consistent with a defense-oriented practice, though his own bio states he represents both plaintiffs and defendants.

Tracked case. Uniloc USA, Inc. et al. v. Electronic Arts, Inc. (E.D. Tex.), defendant side, Carter Arnett, local counsel. Note a sourcing caveat: public dockets for Uniloc's parallel E.D. Tex. campaign (2013–14) show an "Edgar Leon Carter" entering appearances for the Uniloc plaintiffs in companion suits against Epic Systems, Cerner, eMDs, Computer Programs and Systems, and in the Activision Blizzard matter — i.e., plaintiff-side local counsel. The structured case list is controlling here, but the side attribution for the Uniloc litigation should be confirmed against the specific Electronic Arts docket before it is relied on.

Notable result. His most prominent verified patent outcome is Fiber Systems International, Inc. v. Applied Optical Systems, Inc., No. 2:06-cv-00473 (E.D. Tex.), where he was lead counsel for AOS (an Optical Cable Corp. subsidiary) and obtained a complete defense verdict in November 2009 on Amphenol's U.S. Patent No. 6,305,849 (fiber-optic connectors), following partial summary judgment and a successful USPTO reexamination that narrowed the asserted claims — an early example of using reexamination as a litigation backstop. He has also written on that strategy ("Using re-examination as a backstop in your defense," Smart Business Dallas, 2008). No IPR/PGR appearances were verifiable in available sources; his USPTO-facing experience appears to be reexamination-driven rather than AIA trial practice.

Firm and bar. Carter is a co-founder and principal of Carter Arnett PLLC (Dallas), renamed Carter Arnett Stahl + Cho Hernandez PLLC in July 2026. He was previously a name partner at Munck Carter LLP, a Dallas/Marshall patent-litigation boutique (also styled Munck Butrus Carter, P.C.), and before that a partner in the litigation section at Jackson Walker LLP; earlier he served as a Dallas County ADA and Texas Assistant Attorney General. Admitted in Texas (1986) and before the U.S. Supreme Court, the Federal Circuit, the Fifth Circuit, and the E.D./N.D./S.D./W.D. of Texas. Education per his firm bio and Texas Southern University Thurgood Marshall School of Law: B.A., East Texas Baptist University (1980); J.D., Texas Southern (1986). (A Best Lawyers profile lists a University of Texas J.D., which conflicts with the firm and law-school accounts and appears to be an error.)
