Patrick Doyle

I'll research this attorney before drafting.

Let me pin down which Patrick Doyle is counsel of record for Vertiv.

Let me disambiguate the various Patrick Doyles and confirm the Nixon Peabody associate's career.

Patrick Doyle — patent litigation practice summary

Focus areas. Doyle is a patent litigation associate at Nixon Peabody LLP in San Francisco and a registered patent attorney (USPTO Reg. No. 77713) with an electrical engineering background (BS, Marquette University). His firm biography describes a patent-litigation-focused practice spanning software, semiconductors, medical devices, speech recognition, mobile gaming, virtual reality, object-tracking/RFID, and pharmaceuticals/cosmetics, and states he handles matters before the PTAB and the ITC. His one tracked matter sits in data center infrastructure: the accused technology is Vertiv's Liebert cooling equipment and iCOM/iCOM-S monitoring and control systems, and the asserted patents (HPE-origin '277, '287, '179, '870, '682, etc.) claim data center cooling and thermal-management methods.

Side preference. The tracked data shows one appearance, on the plaintiff side as counsel. That label is somewhat formalistic here: Vertiv Corporation v. Valtrus Innovations Ltd. is a declaratory-judgment action brought by Vertiv — an operating company — against Valtrus Innovations, an Irish assertion entity holding an HPE patent portfolio (with Key Patent Innovations as trust beneficiary), after Valtrus sent notice letters to roughly 14 Vertiv customers. Functionally, the tracked matter reflects defense of an operating company and its customer base against an NPE-style assertion campaign; Vertiv's theory was that it is contractually obligated to indemnify those customers. His firm bio states he represents both plaintiffs and defendants, and firm-published coverage credits him with representing the patent-owner plaintiff in a 2026 default-judgment win (below), so the record does not support a single-side characterization.

Firm context. Nixon Peabody is his current firm; the Vertiv engagement is staffed from the firm's IP group (Timothy P. Maloney lead, with Daniel J. Schwartz, Matthew Werber, Allison Strong, Nicole Sims, Randal Alexander, and Doyle). Law360 separately lists a "Patrick Doyle" at Axinn Veltrop in San Francisco in patent cases (Mayborn (UK) Ltd. v. Comotomo, S.D.N.Y. 2022 / N.D. Cal. 2023); that is plausibly the same attorney but I could not verify the link, and at least two other unrelated attorneys share the name (a Thompson Coburn partner in Chicago and a Georgia-based patent lawyer, Patrick Doyle Lowder).

Notable matters and PTAB. In the tracked Vertiv case, the team survived Valtrus's motion to dismiss for lack of declaratory-judgment jurisdiction and defeated transfer to E.D. Texas at the district-court stage (case later transferred/consolidated); Vertiv petitioned for IPR of the '287 patent (IPR2025-00667) and the '179 patent, and the Judicial Panel on Multidistrict Litigation centralized the related Valtrus data center litigation as MDL No. 3190 in E.D. Texas over Vertiv's opposition. At the October 14, 2025 Markman hearing the court struck Valtrus's late counterclaim purporting to join 25 additional parties and 200 John Does. Note: the IPR petitions in the public filings I reviewed list Maloney, Schwartz, Werber, and Strong — not Doyle — so his personal PTAB appearance on that docket is not documented, even though his firm bio claims PTAB experience. Separately, his firm's site reports that he and San Francisco partner Brandon Stroy represented patent owner Performance Solutions in a 2026 ruling against Amazon seller PowX Inc. (default judgment, trebled damages, and $650,000 in fees, for a total over $1.7 million, plus findings of fraud and malicious prosecution); that item rests on firm-published coverage and the underlying order was not independently reviewed here.

Bar and education. Admitted in California, Illinois, and before the USPTO; also admitted in the Northern, Central, Southern, and Eastern Districts of California, the Northern District of Illinois, the Western District of Texas, and the Ninth Circuit. JD, DePaul University College of Law; BS in electrical engineering, Marquette University.
