Jonathan L. Hardt is a plaintiff-side patent litigator whose practice centers on infringement suits for patent-assertion/licensing entities (NPEs). All eight tracked appearances are for plaintiffs — including IoT Innovations LLC, Integral Wireless Technologies LLC, and Liberty Access Technologies Licensing LLC — with no defendant-side representations tracked. His technology mix, per his firm bio and case dockets, spans telecommunications and wireless systems, computer software, web services, mobile devices, encryption, smart-home/IoT platforms, and industrial design; web-verified suits he has appeared in assert wireless-communications and gateway/router patents against operating companies such as Wyze, SimpliSafe, Savant, Monitronics, Snap One, Verizon, D-Link, and Exxon.

Hardt is a partner at Rozier Hardt McDonough PLLC (Austin office), a three-state IP boutique (Austin, Denver, Atlanta) focused on patent and trade-secret litigation and post-grant challenges. His firm bio states that before co-founding the firm he was a partner at an Austin litigation boutique, a counsel in the IP group of a major international firm in Washington, D.C., and a member of the IP litigation group of a Texas-based international firm; third-party data corroborates prior roles at Williams Simons Landis, Wilmer Cutler Pickering Hale Dorr, and Vinson & Elkins. He clerked for Judge David Folsom (E.D. Tex., 2006–07).

Most prominent tracked matters include the multi-case IoT Innovations campaign (e.g., IoT Innovations v. Savant Systems, D. Mass., involving 22 patents and consolidated suits; Jones Day reports the Savant matter settled on favorable terms after court-ordered mediation) and Integral Wireless's wireless-patent enforcement campaign. Firm-published results include securing a venue transfer from N.D. Ill. to E.D. Tex. for Liberty Access in its declaratory-judgment dispute with ASSA ABLOY and a claim-construction reversal for Jetaire Aerospace. On the PTAB side, he has appeared as patent-owner back-up counsel pro hac vice in consolidated IPRs (Giesecke+Devrient v. Lumenco, IPR2024-00836/-838/-839, currency-authentication patents); he is not, on this record, a high-volume IPR petitioner-side practitioner.
