Peter Jason Evangelatos — Patent Litigation Practice Summary

Specialty / focus. Evangelatos is a partner in the IP Litigation group in the New York office of Kirkland & Ellis, where his practice centers on patent litigation and also extends to trademark, copyright, trade secret, and contract disputes, with appellate work before the Federal Circuit. His firm bio describes patent matters spanning cellular, Wi-Fi, semiconductor, audio signal processing, medical device, electrical, data center, and energy technologies; his engineering background (B.S., Mechanical Engineering) underpins that technical work. Tracked matters are consistent with an electronics/consumer-device and standards-heavy docket — Samsung smartphone and audio products, robotic vacuums, and Arm/Qualcomm chip-licensing disputes.

Side preference. All five tracked appearances are on the defendant side, and the verifiable record is weighted toward defending operating companies: Samsung across multiple district court and IPR/PGR matters, and Arm in the Arm/Qualcomm litigations. He is not an NPE/PAE-side filer. That said, his Kirkland work is not purely defensive — he was part of the team that represented iRobot as complainant in an ITC Section 337 action against Shark, and his firm profile states he represents both patent owners and patent challengers in PTAB proceedings. The practical characterization is defense-side for operating companies, with occasional offensive ITC representation of a patent-owning client.

Firm context. Current firm is Kirkland & Ellis (New York). Before Kirkland he was an associate at Barclay Damon LLP (Syracuse, admitted to the New York bar there in 2018) and earlier at Lando & Anastasi LLP (Cambridge, MA); he also served as a judicial intern for U.S. District Judge Lawrence E. Kahn and as a summer associate at Carter, DeLuca, Farrell & Schmidt. He is not in-house.

Notable matters. The most prominent verifiable result is the iRobot ITC action against Shark, in which he was an associate on the Kirkland trial team: ALJ MaryJoan McNamara found iRobot's carpet-detection and auto-docking patents valid and infringed and recommended an exclusion order, and the full Commission later upheld part of that win and issued an exclusion order barring importation of infringing Shark products (covered in The American Lawyer's "Litigator of the Week" runners-up and follow-up items). Other tracked matters include SnapAid, Ltd. v. Samsung Electronics (E.D. Tex., filed 2025), Staton Techiya LLC v. Samsung Electronics (E.D. Tex., with a parallel IPR), Shure Inc. v. Samsung and Samsung v. Sensaphonics (N.D. Ill.), and Arm v. Qualcomm / Qualcomm v. Arm (D. Del.), where he appears in the Arm-side discovery record. In Staton Techiya/Synergy IP the court dismissed the $500M infringement claims against Samsung in 2024 on unclean-hands grounds and referred the plaintiffs' attorneys to state disciplinary authorities; that outcome was reported as a Kirkland team win, but the public reporting I located identifies the team at the partner level rather than naming Evangelatos, so his specific role in that result is not independently confirmed.

PTAB / IPR experience. His Kirkland profile states he is a registered practitioner before the USPTO and "represent[s] patent owners and patent challengers in IPR and EPR [post-grant] proceedings." He is on the district court teams for matters with parallel PTAB challenges (e.g., the Samsung petitions against SnapAid, including PGR2025-00083 and several IPRs, and IPR2022-01106 in the Staton Techiya matter). The PTAB filings I located list other Kirkland attorneys as counsel of record, so his personal appearance as PTAB counsel is not established from the public record even though his broader PTAB practice is described by the firm.

Bar / education. Admitted New York (2018) and Massachusetts (2020); registered to practice before the USPTO. J.D., Albany Law School (magna cum laude, IP Law Concentration, 2017); B.S., Mechanical Engineering, University of Rochester (2014). Federal Circuit and several district court admissions.

Note on sourcing: the technology-area list, PTAB description, and bar/education line come from Kirkland's official bio and a Barclay Damon press release; case-specific details come from court dockets, PTAB filings, and Law.com/Kirkland coverage. Where a matter's outcome is attributable to a Kirkland team rather than to Evangelatos individually, that is flagged above.
