Nathaniel G. Warner

I'll research this attorney before drafting.

Nathaniel G. Warner — Associate, Reichman Jorgensen Lehman & Feldberg LLP (Washington, D.C.; firm bio also lists New York). His patent work sits inside the firm's plaintiff-side monetization campaign for the Valtrus Innovations / Key Patent Innovations portfolio — patents originally acquired from Hewlett-Packard Enterprise covering data center cooling and energy-management technology (e.g., U.S. Patents 6,854,287, 6,862,179, 6,868,682, 6,718,277). The technology mix is mechanical/thermal engineering and control systems — chilled-water and CRAC cooling, sensor-driven airflow control, agent-based energy management — rather than wireless standards or life sciences. His overall docket is broader than patents: the firm describes his practice as complex commercial, criminal, and intellectual property litigation, and Law360 lists him on a 2022 DTSA trade-secret matter (Column5 Consulting Group v. TruQua Enterprises, N.D. Ill.) and a pro hac vice appearance for NatWest Markets N.V. in the S.D.N.Y. bankruptcy proceedings.

Side preference. All three tracked patent appearances are plaintiff side (3–0), and all are filed by Valtrus/KPI against data center operators — i.e., he acts for patent-holding/licensing entities rather than defending operating companies. The dockets confirm this is a coordinated assertion campaign: the same patent family was separately litigated against Vertiv (as declaratory-judgment plaintiff, with a court finding Valtrus lacked § 281 standing absent KPI joinder), SAP, FedEx, Google, and a long list of colocation and data center defendants. Note that the plaintiff/NPE characterization comes from the case list and campaign structure, not from any public statement by Warner.

Tracked cases.

• Valtrus Innovations Ltd. et al. v. EvoDC, LLC (E.D. Tex. 2:26-cv-00286/00287, Judge Gilstrap) — identified as trial counsel; consolidated within the Valtrus data center wave and now part of MDL No. 3190.
• Valtrus Innovations Ltd. et al. v. NTT Global Data Centers Americas, Inc. (N.D. Ill. 1:26-cv-03945, filed April 2026; later transferred to E.D. Tex. by conditional transfer order) — identified as of record.
• Key Patent Innovations Ltd. et al. v. Netrality Properties, LP (N.D. Ill. 1:26-cv-03929, Judge Tharp, filed April 2026) — identified as case team; also drawn into MDL 3190.

No verdicts, settlements, or Federal Circuit results attributable to him in these matters were verifiable; the Valtrus suits were still at the pleading/stay/MDL-transfer stage as of the most recent dockets I could retrieve.

Other notable result. His firm bio credits him as part of the RJLF trial team that secured a complete defense verdict in the DOJ's criminal Sherman Act price-fixing prosecution of ten broiler-chicken industry executives — a win that earned the team The American Lawyer's "Litigator of the Week" recognition. That is a criminal antitrust defense matter, not patent litigation.

PTAB / IPR. I found no PTAB proceeding in which Warner is personally named as counsel. RJLF does appear regularly before the Board for the same Valtrus/KPI/Malikie portfolio (e.g., IPR2026-00120, IPR2025-00668), but the recorded lead and back-up counsel are other RJLF attorneys (Berkowitz, Colsher, Hoang, Hasan). Treat any statement that he handles IPRs as unsupported.

Bar / education. Admitted in New York and the District of Columbia; J.D., Yale Law School (2021), B.A. with honors, Wesleyan University (2017); law clerk to the Hon. Fernando M. Olguin, U.S. District Court for the Central District of California (2023–24 term), rejoining RJLF in D.C. in August 2024. These details come from the firm bio and are consistent with the 2022 pro hac vice order identifying him as a New York bar member.
