Let me dig into the tracked case and the attorney's background at Adobe.

Let me verify the IPR outcome and look for additional professional background.

Michelle Ma — Patent Litigation Practice Summary

Specialty / focus areas. The single tracked matter places Ms. Ma in software and enterprise-messaging litigation: Adobe Inc. v. Peter Henrik Pedersen, the PTAB caption for IPR2023-00986, which she signed for Adobe as petitioner on May 31, 2023, challenging claims 1–11 and 14–18 of U.S. Patent No. 6,965,920 (a "profile responsive electronic message management system" directed to rules-based distribution of electronic messages). That patent was part of a broad assertion campaign by Peter Henrik Pedersen / AiPi Solutions against software and cloud-services companies including Salesforce, Intuit, Zoho, Zendesk, Google, Microsoft, Yahoo, Oracle and Wix, so the practice context is software and internet-services patent defense rather than pharma, Wi-Fi/SEP, or mechanical art.

Side preference. Her tracked profile is entirely defense-side (0 plaintiff / 1 defendant), which is consistent with her role as an in-house litigator for an operating technology company rather than a firm attorney prosecuting NPE/PAE claims. In the related district court action, Peter Pedersen v. Adobe, Inc., No. 6:22-cv-00583 (W.D. Tex., Judge Alan D. Albright), Adobe was the accused infringer and the case was resolved by a written settlement and license agreement; Pedersen's claims were dismissed with prejudice, and the parties jointly moved to terminate Adobe's IPR. The Board dismissed the petition without instituting review on October 11, 2023, and Adobe obtained a refund of its $22,500 post-institution fee.

Firm context. Ms. Ma is in-house at Adobe Inc. (San Jose, California); the State Bar of California record lists Adobe as her employer, and contemporaneous PTAB filings identify her as "Managing Counsel, Litigation, representing Adobe Inc." No prior law-firm history for this attorney is verifiable from published sources — the searches also surface several unrelated attorneys named Michelle Ma (a China-based patent prosecutor at Liu, Shen & Associates; a Santa Clara–educated solo practitioner in San Mateo, Cal. Bar No. 301845; and a litigator at Jones Day/Foley), none of whom should be conflated with the Adobe in-house counsel (Cal. Bar No. 286653).

PTAB / IPR experience. Her documented PTAB footprint is limited to one proceeding, and her role there appears to be that of in-house supervising counsel rather than first-chair: she executed the power of attorney designating Arnold & Porter Kaye Scholer (David A. Caine and Michael J. Sebba) as counsel, and no registered practitioner number is associated with her. There is no basis in the available record to describe her as a regular IPR/PGR advocate. For completeness, the same '920 patent was independently invalidated in a separate IPR brought by Unified Patents (IPR2023-00029, final written decision May 10, 2024), affirmed by the Federal Circuit in Pedersen v. Unified Patents, LLC, No. 24-2090 (Fed. Cir. Mar. 26, 2026); Adobe was not a party to that proceeding.

Bar / education. Admitted to the State Bar of California on December 7, 2012 (Bar No. 286653); J.D., UC Berkeley School of Law. Technology-sector or engineering credentials beyond the bar record are not verified.
