Enrique W. Iturralde — Patent Litigation Practice Summary

Focus areas. Iturralde's docket and firm bio place his practice in electronics- and software-heavy patent litigation: GPS/location tracking and map-based software, telematics and vehicular safety systems, automotive components (direct-injection engines, LED headlamps, windshield wipers), consumer electronics and semiconductors, communications networks, cloud computing, displays and touch-less interfaces, medical devices/telemedicine, fintech/wallet payment, power tools, and footwear. His technical background (M.S./B.S. in electrical and computer engineering) aligns with the hardware/software mix; the tracked matters are all automotive and location/GPS-technology disputes, not life sciences.

Side of the case. The tracked list shows 0 plaintiff-side and 3 defendant-side appearances, but that label is a function of posture rather than alignment. In each tracked matter his client is Longhorn Automotive Group LLC, a patent-assertion entity affiliated with Alpha Alpha Intellectual Partners that is the patent owner/respondent in the IPRs (hence "defendant") even though Longhorn is the plaintiff asserting the patents in the parallel E.D. Tex. infringement suits against Volkswagen, Nissan, Mazda, Hyundai, Mitsubishi and Volvo. Substantively, then, these appearances are patent-owner/assertion-side work. His firm bio and other dockets (e.g., AGIS Software Development, Avant Location Technologies, Semcon IP, and, in the bio, defense of a windshield-wiper supplier and a table-saw manufacturer) indicate he has worked both sides, including defensive representations.

Firm context. He is a partner at Fabricant Rubino & Lambrianakos LLP (also styled Fabricant LLP), Rye, NY / New York, where he litigates before district courts, the ITC, the Federal Circuit, and the PTAB. He previously practiced patent litigation at Brown Rudnick LLP, Shearman & Sterling LLP, and Kenyon & Kenyon LLP, and served as a primary patent examiner at the USPTO before law practice.

Notable matters and PTAB/IPR experience. PTAB work is a central part of his practice — his firm bio states he has represented patent owners and challengers in over 300 IPR and reexamination proceedings, which is corroborated by his repeated role as patent-owner counsel in AGIS Software Development IPRs (Lyft, Apple, Google) and as counsel in registration No. 72,883. In the tracked cases he helped defeat institution of Volkswagen's IPR on U.S. Pat. No. 8,085,192 (IPR2025-00925; discretionary denial Sept. 12, 2025; Director review denied Nov. 2025) and Nissan's IPR on U.S. Pat. No. 7,513,238 (IPR2025-01089; discretionary denial Oct. 17, 2025); he was also on the Federal Circuit brief in In re Volkswagen Group of America, No. 26-123, where the court denied Volkswagen's mandamus petition on Mar. 19, 2026. He argued and lost AGIS Software Development LLC v. Stewart (Fed. Cir. Nos. 23-2236/2237, Rule 36 affirmance June 9, 2025) and was on the brief in AGIS Software Development, LLC v. Google LLC (Fed. Cir. 2021, Rule 36 affirmance). One caution worth noting: in Google's N.D. Cal. declaratory-judgment action over the AGIS patents, Google's amended complaint alleged inequitable conduct by Iturralde and other AGIS counsel during reexamination — an allegation in a pleading, not an adjudicated finding, and I found no public disposition resolving it.

Bar / education. Admitted in New York (2017) and registered with the USPTO (Reg. No. 72,883); J.D., William Mitchell College of Law (now Mitchell Hamline), magna cum laude, 2015; M.S. and B.S., Fairfield University.
