I'll research this attorney's background and practice.

Xin-Yi (Vincent) Zhou — Patent Litigation Practice Summary

Specialty / focus areas. Zhou is an intellectual property litigator whose practice concentrates on electronics, semiconductor, telecommunications, and software technologies — a fit reinforced by his pre-law engineering career as a product engineer at AMD and a process/program engineer and program manager at eSilicon, working on microprocessor design, flash memory architecture, semiconductor processing, and ASIC integration (O'Melveny bio). His tracked and docket-verified matters reflect that technical profile: 3D NAND/flash memory and semiconductor fabrication (Micron v. Yangtze Memory), streaming media delivery and interactive program guide technology (Adeia v. BAMTech/Disney), and video coding, HDR color correction, and user-interface technologies (InterDigital v. Disney). The firm biography also describes work spanning LED/smart devices, GPU and graphics processing, GPS and wireless authentication, IEEE 802.11 Wi-Fi standards, and microprocessor SIMD/instruction-set patents, in district courts in California, Texas, and Delaware, at the ITC (Section 337), and before the PTAB.

Side preference. He works predominantly on the defense side defending operating companies against NPE/PAE and standards-essential patent assertions, though not exclusively. The tracked list is 2 defendant-side to 1 plaintiff-side: he appeared for BAMTech/Disney (defendant, Of Counsel) and for Disney in a second defendant-side matter (of counsel), and for Micron Technology as plaintiff/counterclaim-plaintiff in Micron v. Yangtze Memory (First Back-Up Counsel). The Micron matter is best characterized as a defensive-counterclaim posture — YMTC filed the infringement actions first and Micron asserted patent counterclaims and parallel PTAB challenges. O'Melveny's bio and the tracked matters consistently describe him acting for technology companies accused of infringement, with NPE-asserted patents a recurring theme.

Firm context. He is at O'Melveny & Myers LLP in Los Angeles, where the tracked appearances all originate; there is no sourced indication of prior law-firm history. His tracked roles in the data are "Of Counsel" / "of counsel," while O'Melveny's own professional bio page currently titles him "Partner" — the distinction is worth confirming for current pleadings. He has been with the firm at least since 2015 based on PTAB filings.

Notable matters and outcomes. His most prominent tracked matters are the Disney streaming patent disputes: Adeia Technologies/Media Holdings v. BAMTech, LLC et al. (D. Del.), a six-patent assertion against Disney+, Hulu, and ESPN+ entities that ended in a stipulated dismissal with prejudice under Rule 41(a)(1)(A)(ii) on December 29, 2025 — a confidential resolution with no merits ruling on validity or infringement — and InterDigital v. The Walt Disney Company (C.D. Cal. and D. Del.), where Zhou appears on the Disney defense team; that case was stayed on Disney's motion, and Disney also moved for judgment on the pleadings under § 101 directed to three video-coding/HDR patents. In Micron v. Yangtze Memory (N.D. Cal.), he is listed first back-up counsel on the plaintiff/counterclaimant side of a multi-patent 3D NAND and DRAM dispute that spawned a substantial parallel PTAB docket. His firm bio credits him with results including 15 of 16 asserted patents held invalid or not infringed across two Delaware jury trials and appeals, invalidation of asserted claims through IPR with Federal Circuit affirmance, and Alice-based dismissal of three patents; these are firm-characterized outcomes and should be independently confirmed before reuse.

PTAB / IPR experience. Yes — this is a regular part of his practice. He is registered to practice before the USPTO (Reg. No. 63,366), served as lead counsel on a Niantic, Inc. IPR petition, has appeared as back-up counsel in other IPRs, and the firm bio identifies him as lead IPR counsel in matters resulting in patent invalidation affirmed on appeal. He also has ITC Section 337 experience.

Bar / education (one line). Admitted in California (2007) and Texas (2022); admitted to the N.D. Cal., C.D. Cal., W.D. Tex., and the Federal Circuit; UCLA J.D. (Order of the Coif), Stanford M.S. and Cornell B.S. in Materials Science and Engineering.

Sourcing note: the case-specific facts above come from the tracked matter list, PTAB filings, and federal dockets (CourtListener, D. Del., C.D. Cal.); practice-area descriptions and the outcome summaries are drawn from O'Melveny's own biography and should be treated as firm-supplied rather than independently adjudicated results.
