Warren H. Lipschitz

I'll research this attorney's background before writing the summary.

Warren H. Lipschitz — McKool Smith (Dallas, TX)

Specialty / focus. Lipschitz's tracked docket is concentrated in standards-essential patent (SEP) litigation, particularly cellular and video-coding standards — LTE/WCDMA/GSM, H.264/HEVC video coding, and Wi-Fi (802.11n) — with Wi-Fi standards work reflected in the Ericsson v. D-Link/Intel router-and-laptop litigation. Firm and directory materials describe a somewhat broader technology range including medical devices, security software, data compression, haptics, and high-frequency trading, though the tracked matters are dominated by telecom/media standards. This is a SEP/FRAND practice more than a run-of-the-mill mechanical or pharma docket.

Side preference. The structured list shows 5 plaintiff-side and 1 defendant-side appearance, and the pattern is best described as repeat representation of SEP holders rather than classic NPE work. His principal clients are operating companies that license standards portfolios — Nokia and Ericsson — typically appearing as plaintiffs enforcing patents and seeking leverage toward FRAND licenses, while also defending those same clients against charges that their licensing practices or royalty offers are non-FRAND (e.g., Ericsson's defense in the HTC FRAND breach-of-contract trial, and his defendant-side role in the Nokia/Hisense matter). So: primarily a licensor-side/plaintiff enforcer, but with meaningful defense work in FRAND/antitrust counterclaims. He is not a volume filer for non-practicing entities.

Notable matters. Most prominent tracked matters are the consolidated Nokia Technologies Oy campaigns (Amazon, Hisense, and related defendants) and Voxer, Inc. et al. v. Google, LLC (D. Del., filed July 2025; early-stage, with a motion to dismiss pending as of late 2025 — no outcome yet). He was named lead trial counsel on the defense side in the consolidated ASUS Technology Licensing v. AT&T case, in which McKool Smith obtained a complete defense verdict for AT&T, Verizon, T-Mobile, Ericsson, and Nokia in the Eastern District of Texas (Aug. 26, 2026), defeating $436M in claims with findings of non-infringement, invalidity, and good-faith FRAND negotiation. Firm materials also credit him with roles in the Ericsson v. HTC FRAND jury trial (jury endorsed a $2.50-per-4G-phone royalty; affirmed by the Fifth Circuit) and the Nokia–Lenovo H.264 dispute (settled before ITC hearing). A $145.1M WiLAN v. Apple verdict (C.D. Cal.) frequently attributed in his firm bio was led by Mike McKool, with Lipschitz as an associate on the team — the "won verdicts" framing in some bios should be read with that caveat.

PTAB / IPR. He appears in IPR proceedings as patent-owner counsel for Nokia, admitted pro hac vice in Lenovo v. Nokia Technologies (IPR2020-01096, IPR2021-00038/00039) and related filings. Experience is real but appears tied to district-court SEP campaigns rather than a high-volume standalone PTAB practice.

Bar / education. J.D. magna cum laude, Northwestern University School of Law (2011), Order of the Coif; B.S. and M.E. in civil (structural) engineering, UT Austin and UT Arlington; formerly a licensed Texas Professional Engineer. Available sources list admission to the E.D. Tex. and the Federal Circuit; a Texas state bar admission is likely but not directly verified in the sources reviewed. No prior law-firm history is documented — his entire litigation career appears to have been at McKool Smith, where he became a principal effective January 1, 2019.
