Michael S. Weinstein

Specialty / focus areas. Michael S. Weinstein is an intellectual-property litigation partner in Benesch, Friedlander, Coplan & Aronoff LLP's Cleveland office, where he has practiced since joining in June 2018 and was promoted to partner in January 2022. His firm profile describes a district-court and PTAB patent practice spanning pharmaceuticals (both branded and generic-side Hatch-Waxman work), agrochemical, chemical, medical device, consumer products, automotive, software, and semiconductor matters — consistent with his chemical engineering background. His tracked docket, however, is concentrated in a single technology area: consumer LED lighting. All four tracked appearances are in Feit Electric's campaign to enforce its white-LED filament patents (e.g., U.S. Patent No. 8,604,678) against Savant Technologies LLC d/b/a GE Lighting, Elong International USA, and related parties.

Side preference. The tracked matters skew plaintiff-side (3 of 4 appearances, all as lead counsel or attorney of record for Feit Electric), but the picture is not an NPE/PAE practice — Feit is an operating company enforcing its own portfolio, and Weinstein's fourth appearance is defendant-side local counsel. His broader practice is genuinely two-sided: the firm emphasizes both branded- and generic-side Hatch-Waxman defense, and court records show him admitted pro hac vice in 2024 defending Accord Healthcare in the In re Selenious Acid Hatch-Waxman MDL (D.N.J.). He does not appear to specialize in NPE monetization.

Firm context and notable cases. Weinstein has been at Benesch since mid-2018; I could not verify any prior firm from public sources. His headline tracked cases are Feit Electric Co. v. Savant Technologies LLC d/b/a GE Lighting (N.D. Ohio, filed March 2024), where he signed the complaint as lead counsel, and Feit Electric Co. v. Elong International USA, Inc. et al. (N.D. Tex., filed May 2024). A December 2022 Law360 report — "LED Co. Must Pony Up for Bulb Maker in IP Row" — names him as counsel in a related LED dispute. His firm bio further claims membership on the trial team that won the record $2.54 billion verdict in Idenix v. Gilead (later overturned for lack of enablement) and a separate multi-million-dollar Delaware jury verdict in a contract/trade-secret case; I could not independently verify his role in the Idenix trial, and the award was vacated.

PTAB/IPR and credentials. Weinstein appears regularly in IPR/PGR work — his bio cites all phases of inter partes review, including petitions, patent-owner responses, and oral hearings (including POP responses that defeated four IPR petitions). He is currently counsel to patent owner Feit in consolidated IPRs IPR2024-01357 and IPR2025-00260, in which the PTAB instituted review of the '678 patent and oral argument was set for February 2026. Education/bar: B.S. chemical engineering, University of Cincinnati (2005, cum laude); J.D., University of Cincinnati College of Law (2008, summa cum laude, Order of the Coif); Ohio bar (2008); registered USPTO practitioner (Reg. No. 62,446); Ohio Super Lawyers Rising Stars honoree (2016–2022).
