Alexander J. Nemtzow

I'll research this attorney's background and verify details through web search.

Let me verify the tracked cases and PTAB experience.

Alexander J. Nemtzow — WilmerHale (Boston)

Focus areas. Nemtzow concentrates on patent litigation, post-grant (PTAB) proceedings, and patent counseling. His docket spans medical devices (notably RF-ablation devices for nasal-airway/rhinitis treatment), telecommunications and mobile devices, semiconductors and integrated circuits, and consumer products, and his firm bio also lists quantum computing, robotics, data compression/management, IoT, optics, and batteries. Before law school he worked as a USPTO patent examiner in electrical/magnetic measuring-and-testing art (digital and analog circuit testing, semiconductor device evaluation, capacitive touch screens, position encoders, automotive sensors), which is consistent with the electronics-heavy technology mix he now handles.

Side preference. His tracked practice skews defense-side (2 plaintiff-side vs. 4 defendant-side appearances), and the work is concentrated on operating companies rather than NPE/PAE plaintiffs. Most of the tracked appearances arise from representing Neurent Medical in the consolidated Neurent/Aerin/Foundry dispute, where he appears both defending infringement claims and prosecuting Neurent's own patents and counterclaims. His PTAB work is likewise on behalf of operating companies (PNC Bank, Regions Bank, Apple, Bombardier, Neurent).

Firm context. He has been at Wilmer Cutler Pickering Hale and Dorr for his entire post-law-school career, based in Boston; he was elevated to partner effective January 1, 2026, and practices in the firm's IP Litigation and IP Counseling/Prosecution groups. Note the firm has a second similarly named IP attorney — his identical twin Zachary Nemtzow, also a WilmerHale partner — so results should be attributed carefully.

Notable matters. His most prominent tracked matter is Aerin Medical Inc. & The Foundry, LLC v. Neurent Medical Inc. (D. Del. C.A. No. 23-756, consolidated with 24-1070), concerning nasal-airway medical devices; he appeared at the April 2025 PTAB oral argument for Neurent, and the Board's July 2025 final written decisions held all challenged Aerin/Foundry claims unpatentable. Related IPRs (IPR2024-00277, -00278, -00279, -00280, -00282, -00669) proceeded in parallel, and the resulting appeals are pending at the Federal Circuit (Nos. 25-2099, 25-2100, 25-2101). He was also part of the WilmerHale team that won PTAB invalidation of three USAA mobile-banking patents for PNC Bank (IPRs 2021-01070, -01073, -01077), a result PNC used to challenge a $218.5 million district-court verdict, and he has appeared as back-up counsel in Apple v. Unwired Planet (IPR2020-00642), Bombardier Recreational Products (IPR2024-01108), and Regions Bank v. USAA (IPR2025-01326).

PTAB/IPR experience. This is a core part of his practice rather than an occasional sideline; he is listed as lead or back-up counsel across numerous IPRs in the Neurent, PNC, Apple, Bombardier, and Regions Bank matters, argued before the Board, and was recognized among the top 100 PTAB Litigation attorneys in Patexia's 2025 report.

Bar/education. Registered to practice before the USPTO (Reg. No. 82,130); J.D., University of Virginia School of Law (2017); B.S. in Physics and B.A. in Political Science, University of Massachusetts Amherst (2012, summa cum laude).
