Thanh Dinh Nguyen — patent litigation practice summary

Focus areas. Nguyen is a Dallas-based litigation associate at Winston & Strawn (now Winston Taylor following the firm's June 1, 2026 combination with Taylor Wessing's UK-led business). His only tracked patent appearance is on the defense side of Valtrus Innovations Ltd. v. SAP America, Inc. (E.D. Tex., No. 2:24-cv-00021-JRG, Judge Gilstrap), which involved enterprise-software patents from the ex-HP Valtrus portfolio — fault-tolerant storage and messaging (U.S. 6,889,244), "zero-latency enterprise" data services (7,313,575), and related archiving/monitoring patents. The public record does not show him as a Wi-Fi/standards, pharma, or mechanical-patent specialist; his firm bio describes a broad litigation and appellate docket in which patent infringement is one component alongside trade secrets, commercial contracts, products liability, consumer-protection class actions, and constitutional/administrative matters.

Side preference. The tracked data is 0 plaintiff-side / 1 defendant-side, and that one matter is squarely defensive: representing an operating company (SAP America / SAP SE) against an NPE asserting acquired patents. Nothing in the available record shows plaintiff-side or NPE/PAE representation. The caveat is sample size — a single tracked appearance is thin evidence of a durable side preference.

Firm context and notable matters. He has been with Winston & Strawn in Dallas (bar registration records list the firm from at least 2023 onward); no prior firm or in-house affiliation is reflected in the sources reviewed. In Valtrus, he was part of the SAP team — with Katherine Vidal, Michael Bittner, M. Brett Johnson, and Thomas Melsheimer — that petitioned the Federal Circuit for mandamus seeking intra-district transfer from the Marshall to the Sherman division; the petition was denied in In re SAP America, Inc., No. 2025-118 (Fed. Cir. Apr. 10, 2025) (per curiam). SAP also pursued parallel IPRs (e.g., IPR2025-00416, IPR2025-00419) and a Delaware declaratory-judgment action, and the Texas case ultimately ended by joint dismissal with prejudice reflecting a settlement, reported by Law360 in December 2025. His firm bio also claims representation of a software company in a Federal Circuit mandamus proceeding that produced a precedential venue opinion; I could not verify which decision that refers to, so treat it as unconfirmed.

PTAB/IPR experience. No PTAB filings naming him individually surfaced in the searches performed. He has been on teams in matters with parallel IPR activity, but regular IPR/PGR appearance is not established.

Bar and education. Admitted in Texas, New York (2021), and the District of Columbia; J.D., Georgetown University Law Center (2020); B.A./M.A., Stanford University (2014). He previously clerked for Magistrate Judge Kimberly C. Priest Johnson (E.D. Tex., ret.), Judge Marina Garcia Marmolejo (S.D. Tex.), and Judge Beth Robinson (Second Circuit). Note that multiple attorneys share this name — the Law360 docket page for a "Thanh D. Nguyen" at Winston & Strawn also lists Toyota product-liability and Texas school-district civil rights matters, which are consistent with the same Dallas associate based on his firm bio, but I could not independently confirm that identity match.
