Eric Hui-Chieh Huang

I'll research this attorney before drafting.

Eric Hui-Chieh Huang — Quinn Emanuel Urquhart & Sullivan (New York), Partner

Specialty / focus areas. Huang's patent practice spans a wide technology range rather than a single vertical. His firm biography and docket activity show work in wireless communications (cellular, WLAN, Bluetooth), semiconductors and semiconductor processing, error-control coding (turbo codes, LDPC), digital video/audio compression, LCD/fiber-optics and circuit technologies, pharmaceutical formulations, and consumer/mechanical products. The latter category dominates his currently tracked matters: both sides of the Harbor Freight Tools / Champion Power Equipment dispute over patents covering multi-fuel generator fuel systems, selector switches, and electronic engine control. He also maintains a substantial blockchain/crypto patent and commercial litigation practice (smart contracts, decentralized finance, token and wallet issues).

Side preference. The tracked docket is mixed — 2 plaintiff-side and 3 defendant-side appearances — but the counts partly reflect mirrored filings in a single dispute. He is listed as counsel for Harbor Freight Tools as plaintiff (declaratory judgment of non-infringement, C.D. Cal. No. 2:24-cv-08722) while also appearing in the parallel Champion Power Equipment v. Harbor Freight action on the defense side. His other tracked roles are defense-side, consistent with a practice weighted toward defending operating companies and accused infringers. He does, however, also represent patent-owner plaintiffs such as NantWorks/Nant Holdings IP in assertion litigation.

Firm context. He is a partner in Quinn Emanuel's New York office, where his practice is centered on IP litigation. He was previously associated with the firm as counsel of record on earlier matters at the same Madison Avenue address; no other firm history is confirmed in the sources reviewed. Best Lawyers and World IP Review both list him under Quinn Emanuel for patent litigation.

Notable cases / outcomes. The most prominent verified results: The Hillman Group, Inc. v. KeyMe, LLC (E.D. Tex., No. 2:19-cv-00209), where Huang was part of the Quinn trial team (with Sean Pak and David Nelson) that obtained a complete defense verdict on April 12, 2021 — the jury found no infringement of any of 18 asserted claims across six patents and invalidated a majority of the challenged claims. He represented NantWorks/Nant Holdings IP as plaintiff against Bank of America and others (C.D. Cal. No. 2:20-cv-07872); on October 18, 2024, the Federal Circuit affirmed PTAB final written decisions upholding all challenged claims of four NantWorks patents. In Veritaseum Capital, LLC v. Coinbase Global, Inc. (D. Del. No. 1:22-cv-01253), an early smart-contract patent case, he was pro hac vice counsel for Coinbase and provided the supporting declaration to Coinbase's Rule 12(b)(6) motion; the case was terminated in May 2023 after the plaintiff voluntarily dismissed. He also has ITC experience, including work for Sony in Inv. No. 337-TA-1058 (FujiFilm) and for Samsung in Inv. No. 337-TA-796 (Apple).

PTAB / IPR experience. Huang appears regularly in IPR proceedings, for both petitioners and patentees. He is counsel for petitioner KeyMe in the KeyMe v. Hillman IPRs (e.g., IPR2020-01028, IPR2020-01485), served as counsel for patent owner NantWorks in IPRs against six patents (two denials of institution and four final written decisions, affirmed on appeal), and is part of the Harbor Freight team that filed a large wave of IPR petitions against Champion Power Equipment's generator patents (IPR2025-00805, -00951, -01272 and others), where he filed supporting declarations and negotiated Sotera-plus stipulations with the district court. Note that lead PTAB counsel in the Harbor Freight proceedings is listed as Foley & Lardner, with Huang acting as district-court litigation counsel.

Bar / education. Admitted in New York (1998) and registered to practice before the U.S. Patent and Trademark Office; J.D., George Washington University Law School (1997); B.S.E. in materials science and engineering, University of Michigan. Before law school he worked as an electronic packaging engineer at National Semiconductor.
