Alexander Nemtzow

I'll research this attorney before drafting the summary.

Let me research the tracked cases and any notable outcomes.

Let me verify bar admissions and a few remaining details.

Alexander J. Nemtzow — Wilmer Cutler Pickering Hale and Dorr (Boston)

Focus areas. Nemtzow's practice centers on patent litigation, post-grant proceedings and patent counseling. WilmerHale's bio credits him with matters spanning medical devices, telecommunications networks, quantum computing, robotics, integrated circuits and semiconductor fabrication, data compression and management, IoT, mobile applications, optics, batteries and consumer products. The tracked docket is concentrated in medical devices: the Aerin Medical / Neurent Medical / The Foundry dispute over radiofrequency nasal-airway and chronic-rhinitis treatment technology (D. Del.), where he appears for Neurent. His technical background is in electrical/electromechanical arts — he was a USPTO patent examiner before law school, examining electrical and magnetic measuring and testing applications (semiconductor device evaluation, capacitive touch screens, position encoders, automotive sensors).

Side preference. The tracked appearances are evenly split (4 plaintiff, 4 defendant), and he works both challenger and patent-owner positions. He has served as back-up counsel for Neurent in district-court actions on both sides of the Aerin/Foundry/Neurent conflict, as "petitioner's counsel" in a post-grant matter, and — per USPTO filings in other matters — as counsel to patent owners defending IPRs (e.g., Regions Bank v. USAA). There is no evidence he represents NPEs/PAEs as a business model; the client base in tracked matters is operating companies in the medical-device space.

PTAB / IPR experience. This is a core part of his practice. WilmerHale states he was among the top 100 attorneys in PTAB litigation in Patexia's 2025 PTAB Litigation Report, and he appears as counsel of record on numerous IPRs, including the Neurent-side petitions challenging Aerin and Foundry nasal-airway patents (IPR2024-00277, -278, -279, -280, -282, -669) and the later Aerin-side petitions against Neurent patents (IPR2025-01124–01127). He also has deposed expert witnesses in those proceedings.

Notable matters and outcomes. The most prominent tracked work is the consolidated Aerin Medical / The Foundry v. Neurent Medical and Neurent v. Aerin litigation (D. Del. C.A. No. 23-756 and 24-1070), an eight-patent assertion over the Neuromark, RhinAer and VivAer sinus/nasal-rhinitis devices, which was stayed pending PTAB review. In July 2025 the Board issued final written decisions holding all challenged claims of several Aerin/Foundry patents unpatentable on the Neurent-side petitions — a client-side win reported by Law360 — and on August 27, 2026 the Federal Circuit dismissed the resulting appeals (Nos. 2025-2099 et al.) by agreement of the parties. He has also appeared pro hac vice in consumer-product litigation in the District of New Jersey (SharkNinja Operating v. RJ Brands).

Firm and credentials. Nemtzow has been at WilmerHale since 2017, joining from the USPTO, and was elected partner effective January 1, 2026 (he is listed in the tracked docket variously as back-up counsel, counsel and partner, consistent with that progression). Education: JD, University of Virginia School of Law, 2017; BS in Physics and BA in Political Science, University of Massachusetts Amherst, 2012. He is registered to practice before the USPTO (Reg. No. 82,130); his specific state bar admissions were not verified in the sources reviewed.

Note: the case list supplied does not identify the attorneys' roles with certainty for the two "Untitled" entries, and some docket labels in the source data (e.g., party-side designations in PTAB matters) are ambiguous; the descriptions above follow the party alignments shown in the public IPR and district-court filings.
