Jonathan S. Tse

I'll research this attorney's professional background before drafting.

Practice Summary — Jonathan S. Tse (Quinn Emanuel Urquhart & Sullivan)

Focus and technology areas. Tse's practice centers on intellectual property and patent litigation in federal district courts, the ITC, and arbitration, with an engineering-heavy docket. His tracked matters involve server and storage hardware, memory modules, and power/thermal management: the Cloud Byte patents (asserted against Dell) cover data-storage and ICT-equipment abnormality-detection technology, while his publicly documented work for Google concerns DDR4/DDR5 memory modules and JEDEC standard-setting. He holds a B.S. in mechanical engineering (UCLA, 2011), consistent with the hardware-/mechanical-arts orientation of his matters. Nothing in the record indicates Wi-Fi/standards-essential patent or pharmaceutical work.

Side preference — with a caveat. The authoritative tracked dataset is 7 of 7 plaintiff-side (0 defendant), spanning the Cloud Byte litigation and PTAB matter plus five untitled appearances, in which he is variously styled lead counsel, counsel, or "attorney for plaintiff." That profile is that of a patent-owner/NPE-side advocate: Cloud Byte is an acquired-patent licensing entity. However, public court records clearly show the same attorney (CA Bar No. 305468, same firm email) acting for a defendant operating company in patent matters — most notably as part of Quinn Emanuel's team representing Google LLC and Alphabet in Netlist, Inc. v. Google LLC and the related Delaware Samsung v. Netlist action. Those appearances are not reflected in the tracked counts, so the dataset appears to undercount his defense-side work; the accurate description is that he has worked both sides, with reported appearances concentrated on the patent-owner side.

Firm context. Tse has been at Quinn Emanuel since 2015 and is currently of counsel in the firm's San Francisco office (previously listed as an associate). No prior law-firm history surfaced in the searchable record. He is admitted to the State Bar of California (Dec. 3, 2015) and registered to practice before the USPTO; J.D., University of Virginia School of Law (2015).

Notable matters and outcomes. Cloud Byte LLC v. Dell Inc. (E.D. Tex., No. 2:24-cv-00637, filed Aug. 2024) is his most prominent tracked case — a seven-patent assertion against Dell over PowerEdge servers and storage products, in which Quinn Emanuel represents Cloud Byte. The parallel PTAB proceedings (Dell Techs. v. Cloud Byte, IPR2025-01284/01286/01287/01288) went the patent owner's way: the Director denied institution on Nov. 20, 2025, and Dell's refund requests followed in January 2026. Separately, in In re Subpoena to Quinn Emanuel, No. 2:25-mc-00003 (E.D. Tex.), the court denied Dell's motion to enforce a subpoena seeking Quinn's patent-transfer and license documents, limiting Dell's effort to bypass ordinary non-party discovery. His documented Google work includes the long-running Netlist memory-module litigation (license/exhaustion defenses, motions to strike and stay, JEDEC-related discovery).

PTAB / IPR experience. Minimal but present. He is tracked as counsel in IPR2025-01286 (Dell v. Cloud Byte), on the patent-owner side. The Quinn Emanuel PTAB team on that matter was led by James M. Glass, with John T. McKee and Quincy Lu as back-up; Tse is not identified as lead PTAB counsel in the mandatory notices, so his IPR role appears supportive rather than as first chair. No substantial standalone PTAB practice is verifiable from the sources reviewed.

Note on sourcing: bio details above come from Quinn Emanuel's attorney page and the State Bar of California record; case facts come from federal court filings, the PTAB docket, and the E.D. Tex. subpoena opinion. The tracked 7-0 plaintiff count conflicts with documented Google defense-side filings by the same bar number — flagged above rather than reconciled.
