Steven Mark Geiszler — Patent Litigation Practice Summary

Specialty / focus. Geiszler is a career patent litigator whose matters center on telecommunications and connected-device technologies — standard-essential patents (SEPs), Wi-Fi/5G wireless standards, FRAND licensing, consumer electronics, semiconductors, computer networking, and streaming software. His current tracked work is defense-side: he represents TCL Electronics Holdings and related entities in Flexiworld Technologies, Inc. v. TCL Electronics Holdings Ltd. et al. (E.D. Tex., No. 2:26-cv-00229, Judge Gilstrap), an NPE assertion of wireless-connectivity and content-streaming patents against TCL TVs, soundbars, headphones, and phones. Both tracked appearances (attorney of record and lead counsel, Geiszler Law Firm) are in that Flexiworld/TCL defense engagement; his broader career (150+ patent cases as counsel of record per firm and conference bios) spanned district courts, the ITC, and the Federal Circuit, with reported work in semiconductors, consumer electronics, networks, and pharmaceuticals.

Side preference. His tracked docket is entirely defendant-side, and the weight of his career is defense of operating companies: at Huawei he managed 70–80+ U.S. matters defending against NPE and competitor assertions and SEP/FRAND claims. Sources (IPWatchdog, Above the Law) also note he has appeared for plaintiffs, and he ran Huawei's offensive assertion campaigns — including the Huawei–Verizon SEP suits settled mid-trial in 2021. He is therefore best characterized as primarily an operating-company defense and licensing counsel who has also led patent-enforcement/licensing programs.

Firm context. Geiszler founded Geiszler Law Firm PLLC (Dallas) in 2026 after roughly a decade in-house as Huawei's U.S. Chief IP Litigation/IP Counsel (based at Futurewei Technologies, Plano, TX), where he oversaw U.S. litigation, licensing, and prosecution. Before that he spent 15 years in Dallas at Jones Day (associate), Gibson Dunn (associate), and Dentons (IP litigation partner). He now focuses on global patent licensing and SEP/FRAND work with Huawei as an anchor client, and sources credit him as lead negotiator or core team member on eight- and nine-figure licensing deals aggregating roughly $2 billion.

Notable cases / PTAB / bar. His most prominent verified result is the closely watched Huawei v. Verizon pair that settled mid-trial (2021), which Above the Law and IAM describe as a bellwether SEP-enforcement victory he helped architect; he also led the 2026 Huawei–HP global Wi-Fi cross-license and related SEP pool negotiations. No reliable evidence shows a regular PTAB/IPR practice — his work has centered on district court, ITC, and licensing/mediation (he participated in the UPC Patent Mediation and Arbitration Centre's 2026 inauguration program). Bar/education: Texas bar (2001), USPTO-registered (2002); J.D., University of Virginia School of Law (2001); B.A., Baylor University (1995).
