Professional Summary — Donald H. "Trey" Mahoney III (1972–2022)

Mahoney was a Houston-based patent litigator whose single tracked appearance places him plaintiff-side: Peter Henrik Pedersen v. Ziff Davis, Inc. (6:22-cv-00597, W.D. Tex., filed June 2022 before Judge Albright), where he was of counsel at Ramey LLP on the plaintiff's team alongside William P. Ramey III and Kyril Talanov. The case — part of inventor Pedersen's multi-defendant campaign over U.S. Patent 6,965,920, directed to electronic-message/email management — reflects his work on software and communications-technology infringement matters, though his firm biography describes broader exposure across biotech, genetically modified organisms, consumer electronics, signal processing, oil-and-gas drilling equipment, medical devices, and pharmaceuticals. Note that Mahoney passed away on August 19, 2022 (Ramey LLP in memoriam; obituary), so his tracked docket reflects the final months of his career; his 2022 Ramey matters were consistently on the patent-owner/plaintiff side of monetization litigation, consistent with Ramey's predominantly plaintiff-side IP practice.

Firm context. Mahoney was counsel/of counsel at Ramey LLP (Houston), an IP boutique known for representing patent owners and monetization entities. He began his career as an associate at Howrey Simon Arnold White, continuing through its merger into Winston & Strawn, before joining Ramey in his later years. His Ramey bio states he focused on litigation, transactional patent matters, and prosecution including post-grant proceedings; he was also registered to practice before the USPTO. Sources such as the Ex Parte/RPX database list him on roughly a dozen 2022 Ramey plaintiff filings (e.g., Wikeshire IP v. Kapsch TrafficCom, Savannah Licensing v. Atlassian), though the authoritative tracked case count is one.

Notable cases and PTAB/IPR context. His only tracked matter, Pedersen v. Ziff Davis, was part of the larger Pedersen email-management campaign; the underlying '920 patent was later challenged in multiple IPRs (e.g., IPR2023-00029, IPR2023-00867, IPR2023-00986) and ultimately affirmed invalid by the Federal Circuit in 2026 — but Mahoney was not lead counsel in those PTAB proceedings, and posthumous courtesy-copy lists still carried his Ramey email. His firm bio advertises experience in post-grant proceedings, but I found no independently verified IPR where he appeared as counsel of record.

Bar/education. B.S. biochemistry, University of Texas (1996); M.S. biochemistry, University of Houston (1999); J.D., University of Houston Law Center (2004, Law Review). Admitted Texas (2004), USPTO, D. Del., and the Federal Circuit (Martindale profile). Disambiguation note: identity confirmed via Ramey LLP's in-memoriam page and Martindale; no conflicting same-name practitioner was found.
