Dori Ann Hanswirth

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

Let me check the tracked case and whether she has any patent/IPR history.

One more check on the specific tracked case.

Professional Summary — Dori Ann Hanswirth

Note on framing: The structured case list labels this as "patent litigation" coverage, but the sources do not support that characterization. Hanswirth's docket and firm bios place her in trademark, copyright, media/First Amendment, defamation, and right-of-publicity litigation — not patent litigation. The single tracked matter ("Petitioner v. Wiz, Inc.") corresponds to no verifiable patent case in which she appears; web searches surfaced no patent docket, patent verdict, or patent-focused engagement for her.

Specialty / focus areas. Hanswirth is a New York-based IP and media litigator at Arnold & Porter, where she co-leads the firm's Technology, Media & Telecommunications industry group. Her technology areas are software and hardware branding, fintech/mobile applications, social media and internet services, AI training and generative-AI content issues, and consumer/entertainment brands — trademark enforcement and prosecution, copyright and fair use, false advertising, defamation, and reporters' rights. Arnold & Porter's own firm-level patent work is concentrated elsewhere (life sciences and patent disputes), with Hanswirth recognized by Managing IP as a Copyright Star (2026) and by WTR 1000 for trademark enforcement/litigation. Nothing in her published record shows Wi-Fi/standards, pharmaceutical, or mechanical patent experience.

Side preference. Her tracked appearance is defense-side (1 defendant, 0 plaintiff), consistent with a defense-leaning practice: she has defended ElevenLabs, Adobe, and AlphaSense in infringement suits, and defended media clients in defamation actions. She is not a one-sided defender, however — she also brings affirmative enforcement actions for brand owners (e.g., acting as counsel to Google LLC as opposer in TTAB oppositions) and handles prosecution strategy for corporate portfolios. She is not an NPE/PAE plaintiffs' lawyer.

Firm context. Arnold & Porter Kaye Scholer (New York office). The case list records her role as "Of Counsel"; firm, Chambers, and directory listings consistently describe her as a partner and industry-group co-lead, so the "Of Counsel" designation appears to be a data artifact rather than her current title. Prior firm history could not be verified from the sources reviewed, so no earlier affiliations are stated here.

Notable matters (trademark/copyright/media, not patent). Vacker v. ElevenLabs, Inc. (D. Del.) — defense of an AI voice-generation company against copyright and right-of-publicity claims by audiobook authors and voice actors; she filed the motion to dismiss and a declaration, and the case was voluntarily dismissed with prejudice in November 2025. The Foundry Visionmongers Ltd. v. Adobe Inc. (N.D. Cal.) — trademark defense for Adobe (2026 filings). AlphaSights Ltd. v. AlphaSense, Inc. — trademark defense. Google LLC TTAB oppositions (e.g., Opp. No. 91236326). Media-side results include affirmance by the First Circuit of summary judgment for a national news network on a "fake news" defamation claim, Second Circuit affirmances for Planned Parenthood and a public-health researcher, and a New York Court of Appeals reporter's-shield ruling protecting a journalist's confidential sources.

PTAB / IPR experience. None identified. She appears before the Trademark Trial and Appeal Board (TTAB) in opposition/cancellation matters and before the USPTO on trademark prosecution — not in IPR, PGR, or CBM proceedings.

Bar / education. Admitted in New York (1987); J.D., Yeshiva University Benjamin N. Cardozo School of Law (sources list graduation as 1986 or 1987 — one short line, with that caveat).
