Austin Philip Mayron

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

Let me dig deeper into his current role and the tracked case.

A few more targeted searches to confirm the case outcomes and current role.

Austin Philip Mayron — Patent Litigation Summary

Practice focus. Mayron's verified patent work is concentrated in software and data-security technologies rather than pharma or mechanical arts. His one tracked litigation appearance is as district counsel for the patent owner in Security First Innovations, LLC v. Google LLC (E.D. Va., No. 2:23-cv-00097), a case involving patents on encrypted data parsing, chunking and distributed storage (e.g., U.S. Patents 11,178,116; 10,452,854; 11,068,609). He signed the patent owner's claim-construction correspondence and discovery correspondence in that case. He also co-authored the 2024 IAM Patent Litigation Review chapter "A Primer on US Litigation When It Comes to Software Patents" with S&C's Dustin Guzior and Stephen Elliott, which is the clearest published statement of his subject-matter focus. Note that the tracked case list does not include Wi-Fi/standards-essential-patent litigation; standard-essential patent policy work appears only in his later government role (below).

Side preference and firm context. The structured data shows a single plaintiff-side appearance (1 plaintiff / 0 defendant), representing a patent-assertion plaintiff, so no reliable inference of a repeat "NPE-side" or "defense-side" orientation can be drawn from the docket. S&C described him as a litigation associate and member of the firm's IP & technology litigation practice, and as a generalist with patent, commercial, regulatory/white-collar and appellate experience — consistent with a firm that litigates on both sides. His NY bar registration lists Sullivan & Cromwell through 2025 and the U.S. Patent and Trademark Office thereafter.

Notable matters. Beyond the Security First case, he was part of the Sullivan & Cromwell team that secured a settlement for Ocado Group plc in July 2023 in the global warehouse-automation IP disputes publicly referred to as the "Robot Wars." He also appeared on non-patent appellate amicus work for banking associations in East Fork Funding LLC v. U.S. Bank, N.A. (2d Cir.). On the Security First matter, the related PTAB proceedings (IPR2024-00212 through -00215) are documented; institution was denied in IPR2024-00213 against U.S. Patent 9,338,140 (June 6, 2024), a result credited to an S&C team including Andrei Iancu and Stephen Elliott. Mayron's name appears in the PTAB record as the author of a district-court claim-construction letter filed as an exhibit, but the available sources do not show him as counsel of record in the IPRs themselves, so his direct PTAB advocacy experience is not established.

Government role and background. Since approximately 2025 he has been at the USPTO Office of the Solicitor, identified in agency and Federal Circuit filings as Senior Legal Advisor and, in 2026 filings, as Deputy Solicitor; he co-chairs the USPTO's Standard-Essential Patent Working Group with Solicitor Nicholas Matich and has appeared on the Director's appellate briefs (e.g., In re Ablynx N.V., No. 2026-1333). This is a policy/government position, not private patent litigation practice. He holds a J.D. from Washington University School of Law, was admitted to the New York bar in 2019, and previously clerked for Judge Steven J. Menashi (2d Cir.) and Judge Elizabeth L. Branch (11th Cir.); he also served as a deputy associate counsel to the President in the White House Counsel's Office. His admission status in other jurisdictions is not reliably sourced.

Caveat: the tracked case list (one appearance) is thin, and much of the above — particularly the USPTO role — comes from agency announcements, Federal Circuit filings and law-firm publications rather than court dockets for patent suits.
