Alexis L. Ritzer

Practice focus. Alexis L. Ritzer is a registered patent attorney and associate at Carter Arnett Bennett & Perez PLLC (the Dallas trial boutique since rebranded Carter Arnett Stahl + Cho Hernandez). Her firm bio describes a practice representing both plaintiffs and defendants in infringement and validity disputes across telecommunications, semiconductors/circuitry, pharmaceuticals, and mechanical engineering — a breadth consistent with her own scientific background in chemistry, thermodynamics, and fluid dynamics. Her tracked docket is concentrated in LED lighting technology, specifically Feit Electric's U.S. Patent No. 8,604,678 covering white-filament LED bulbs and wavelength-conversion components.

Side and firm context. Of her three tracked appearances, two are as back-up counsel for Feit Electric (the patent-owner/defendant-side) in inter partes reviews filed by Savant Technologies (GE Lighting), Elong International, and Xiamen Longstar; the third is a plaintiff-side appearance in a Savant v. Feit matter. She therefore works both sides rather than maintaining a fixed plaintiff or NPE posture. Before joining Carter Arnett, she served as a judicial extern to Judge Jane J. Boyle (N.D. Tex.) and as a judicial law clerk at the PTAB; she has no prior law-firm history identified.

Notable matters. Ritzer was designated back-up counsel for Feit in the consolidated IPR cluster over the '678 patent — IPR2024-01357 and IPR2025-00260 (instituted/joined June 2025) — and the related Elong matter IPR2025-00258 (discretionary denial); Carter Arnett, including Ritzer, withdrew as Feit's PTAB counsel in August 2025 in favor of Benesch. The parallel N.D. Tex. case, Feit v. Elong, ended in a joint dismissal without prejudice in January 2026. She was also named on the trial team that won a $9.2M Austin jury verdict for Katana Silicon Technologies against GlobalFoundries (July 2025) and filed the W.D. Tex. complaint in ThroughPuter, Inc. v. Google LLC (October 2025).

PTAB/IPR and credentials. IPR/PGR work is a stated practice area and a substantial part of her early career; she is a former PTAB clerk and belongs to the PTAB Bar Association and American Association of Patent Judges. Education: B.S. Chemistry (Southwestern University, 2010), M.S. Atmospheric and Oceanic Sciences (Wisconsin–Madison, 2014), J.D. magna cum laude, Order of the Coif (Texas A&M, 2022). Admitted in Texas (2022), D.C. (2024), before the USPTO (2019), the Federal Circuit (2023), and all four Texas federal district courts.
