Daniel G. Nguyen

I'll research this attorney before drafting, keeping in mind the tracked data is very thin (one untitled appearance).

Note the search results contain a different attorney (Daniel T. Nguyen, NYT v. Microsoft) — I'll exclude that. Let me verify a few more specifics.

Let me verify his litigation roles and any PTAB appearances.

Daniel G. Nguyen — Patent Litigation Summary

Focus areas. Nguyen is a Houston-based IP litigator and USPTO-registered patent attorney whose practice centers on the electrical and computer arts. Firm biographies describe work in telecommunications and wireless communications, financial services and user-authentication technology, oilfield services (downhole perforating systems, drill ships, enhanced oil recovery), power conversion and distribution, lighting (compact fluorescent ballasts, LED), gaming/wagering terminals, solid-state storage and semiconductor memory, ruggedized connectors and industrial networks, and paperboard packaging structures. He came to law from engineering: an electrical engineering degree and five years as an engineer at Texas Instruments (1992–1997), which he and his firms cite as the basis for the hardware- and systems-heavy docket. Nothing in the searchable record shows Wi-Fi/standards-essential-patent or life-sciences/pharma work.

Side preference. The tracked data is thin — a single appearance, entirely on the defendant side (0 plaintiff, 1 defendant), with no case name captured — but it aligns with everything else available. Both his Locke Lord and Troutman Pepper Locke bios consist almost exclusively of defending operating companies against patent assertions (a major U.S. bank, an international airline, a global lighting company, an offshore drilling company, an oilfield equipment manufacturer, a technology conglomerate, a power converter maker), alongside patent prosecution and portfolio work for corporate clients. Law360's docket listing for him includes PAE/NPE-type suits such as PACid Technologies, LLC v. Citibank, N.A. (W.D. Tex., filed March 2024, asserting cryptography/authentication patents) and a Greenthread, LLC v. OmniVision Technologies matter in the Eastern District of Texas — again the defense posture typical of NPE defense. There is no evidence he represents NPEs/PAEs as a plaintiff.

Firm context. He is counsel at Locke Lord in Houston; following the Troutman Pepper–Locke Lord merger effective January 1, 2025, he now practices at Troutman Pepper Locke. His prior career was at legacy IP boutiques and firms: associate at Jenkens & Gilchrist (2000–2007), and patent agent at Rosenthal & Osha (1998–2000) and Fish & Richardson (1997–1998), before which he was an engineer at Texas Instruments. He has spent essentially his whole legal career in private practice, not in-house.

Notable matters, PTAB, and credentials. No verdicts, Federal Circuit decisions, or publicly reported settlements could be verified. The most concrete matter on the record is his representation of a global paper and packaging company in inter partes review proceedings involving paperboard structures (likely tied to WestRock, a frequent applicant in his prosecution data) — a real but isolated IPR data point; there is no indication he is a high-volume PTAB practitioner. His remaining matters are described in firm-bio terms without case names or outcomes. Credentials: J.D., University of Houston Law Center (1999); B.S., Electrical Engineering, Texas A&M University (1992); admitted in Texas (2000) and registered before the USPTO (Reg. No. 42933); admitted in all four Texas federal districts; listed in The Best Lawyers in America for Litigation–Patent (2024–2026). Disambiguation: he is not Daniel T. Nguyen, who appears in the New York Times/Daily News v. Microsoft copyright cases in S.D.N.Y.

Caveat: the authoritative case list contains only one untitled appearance, so the litigation picture above rests mainly on firm biographies, a Law360 docket listing, and the Stanford NPE database rather than a verified docket review.
