Jonathan Lloyd Hardt

I'll research this attorney before drafting.

Good initial data. Let me dig into notable cases and PTAB activity.

Let me search for the remaining tracked cases and any notable outcomes.

Summary: Jonathan Lloyd Hardt — Rozier Hardt McDonough PLLC

Focus areas. Hardt's practice centers on patent litigation, with secondary emphasis on trade secret litigation and IP counseling. His firm biography describes experience spanning telecommunications, wireless communications, computer software, web services, mobile devices, encryption software, agriculture technology, and industrial design of consumer products. The tracked docket is consistent with that: the Integral Wireless Technologies matters assert wireless-standard patents (802.11n/ac/ax Wi-Fi and 4G/5G MIMO/handover functionality) against D-Link, Luminator, Teltonika, and others, while Fleet Connect Solutions v. Tesla, CommWorks Solutions, Alto Dynamics, Vision Works IP, and Fitistics involve software, networking, and consumer electronics. He has also handled matters outside pure patent work, including a security-element/micro-mirror patent dispute (Lumenco) and a consumer-product case (Zugara, Inc. v. Jand, Inc.).

Side preference. He is predominantly a plaintiff-side patent-enforcement lawyer. The tracked appearances run 8 plaintiff / 2 defendant, and in a 2025 PTAB pro hac vice declaration he described his practice as having "helped patent owners enforce their patents, primarily in the area of electronic devices and wireless communications." The two defense-side appearances are local-counsel roles, so the overall picture is a patent-owner/NPE-side practice rather than a mixed operating-company defense practice. Plaintiff clients in the tracked list include well-known assertion entities and smaller patent holders.

Firm context and notable matters. Hardt is a founding partner of Rozier Hardt McDonough PLLC (founded 2021), a patent-litigation boutique whose partners work remotely across states. Before founding the firm he was a partner at an Austin litigation boutique and earlier served as counsel in the IP litigation group of a Washington, D.C. international firm; he returned to Texas in 2016. His most prominent tracked representations include Lumenco, LLC v. Giesecke+Devrient GmbH (E.D. Tex. No. 2:23-cv-00100, dismissed June 2024, with a parallel Court of Federal Claims action), the multi-defendant Integral Wireless Technologies campaign, IOT Innovations LLC v. ADT LLC, and Fleet Connect Solutions LLC v. Tesla, Inc., where he appeared as local counsel. On the Lumenco side, the outcome was adverse: the PTAB's November 2025 final written decisions in IPR2024-00836, -00838, and -00839 held the challenged claims unpatentable, Director Review was denied in March 2026, and Lumenco has appealed to the Federal Circuit. Note that the tracked list includes several "Untitled" entries I could not map to specific dockets, and I found only limited public detail on the tracked Integral Wireless Technologies LLC v. T-Mobile US, Inc. matter.

PTAB / IPR experience. He appears in PTAB proceedings, though as patent-owner counsel rather than as a high-volume petitioner-side filer. He was admitted pro hac vice in the Lumenco IPRs (IPR2024-00836/-00838/-00839) in August 2025; his declaration in those proceedings stated he had no prior pro hac vice PTAB appearances in the preceding three years. His firm's practice includes post-grant challenges.

Bar and education. J.D., St. Mary's University School of Law (2006, summa cum laude; graduated first in class; Solicitations/Articles Editor, St. Mary's Law Journal); B.A. Economics, St. Mary's University (cum laude). Admitted in Texas and the District of Columbia, before the U.S. Supreme Court, the Federal Circuit, and multiple district courts (including E.D. Tex. and W.D. Tex.). He clerked for Judge David Folsom in the Eastern District of Texas (2006–2007).
