Ariane S. Mann

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

Let me dig deeper into her case involvement, PTAB work, and any notable outcomes.

Let me verify her current firm, prior firm history, and any notable IPR or appellate work.

Ariane S. Mann — patent litigation practice summary

Mann is an intellectual property litigator whose practice spans patent, copyright, and trade secret disputes, with patent litigation as the core. Her technical background is in computer science (M.S., University of Tulsa) and she is a former digital forensics analyst; firm bios credit her with experience across data center infrastructure, telecommunications systems, software, mobile/robotics, display devices, data/graphics processing units, microscopes, and tobacco-cessation devices. Her tracked docket work is concentrated in data center power-and-cooling hardware: the Valtrus Innovations campaign, which asserts patents originating from Hewlett Packard Enterprise/Schlumberger-linked portfolios covering atmospheric control, cooling, and power distribution in data centers, and the related declaratory-judgment fight brought by equipment maker Vertiv.

On side preference, the tracked record is overwhelmingly patent-owner/proactive-plaintiff work: six of seven appearances are for plaintiffs, and even the single defendant-side appearance (Vertiv Corp. v. Valtrus Innovations Ltd.) is Mann defending the same patent-asserting client against Vertiv's declaratory-judgment complaint. The plaintiff-side matters largely involve Valtrus Innovations Ltd., an Irish entity described in court filings as a subsidiary/beneficiary structure of Key Patent Innovations and characterized as a non-practicing entity. So in tracked matters she aligns with the NPE/patent-assertion side rather than the operating-company defense side, though firm bios describe broader IP counseling and defense-adjacent work.

Firm context: all seven tracked appearances are attributable to Reichman Jorgensen Lehman & Feldberg (RJLF), a majority women-owned national trial firm, where she is listed in its Washington, D.C. office. Court records show her withdrawing as counsel in the Valtrus/NTT Data matter in April 2026, and she is currently listed as a "Senior Attorney" in the Dallas office of AZA (Ahmad, Zavitsanos & Anaipakos), an IP-litigation focused firm; her bios state she practiced at three global law firms before joining RJLF. Notable tracked matters include the Valtrus suits against Digital Realty, Equinix, TierPoint, DataBank, and Lumen (E.D. Tex.), and the Valtrus v. NTT Data/CyrusOne lead case in which Vertiv intervened and litigated declaratory-judgment jurisdiction and indemnity issues. The TierPoint action was resolved by a joint dismissal with prejudice at the parties' request (no merits ruling). Public-record rulings in the broader Valtrus campaign — including Alice-based subject-matter dismissals and a claim-splitting dismissal in the Google litigation (N.D. Cal.) — went against Valtrus, but Mann's direct role in those Google matters is not established by the sources reviewed.

PTAB/IPR experience: she appears in Patent Trial and Appeal Board materials as counsel — for example, in the AMD/Pensando IPRs against Concurrent Ventures and in connection with the Valtrus-related IPRs — and firm bios cite district court, Federal Circuit, ITC, and PTAB experience, including IPR petition drafting. That said, the public record shows her more often in district-court litigation roles than as a named IPR lead counsel, so her PTAB work appears supportive rather than a primary practice concentration. Bar and education: J.D., Harvard Law School (2017); M.S., Computer Science, University of Tulsa (2012); B.S., Cornell University (2011); clerked for the Hon. Kara F. Stoll, U.S. Court of Appeals for the Federal Circuit; admitted in Texas, the District of Columbia, and the Federal Circuit, with district court admissions in the E.D. Tex., N.D. Tex., and M.D. Ga.

Note: some details above (current AZA role, exact departure timing from RJLF, and the identity of her three prior firms) come from firm bios and docket entries rather than a single authoritative confirmation; where the record is unclear I have flagged it rather than asserted it.
