Gregg F. LoCascio — Patent Litigation Practice Summary

Gregg F. LoCascio is a Washington, D.C.–based IP trial partner at Kirkland & Ellis who leads the firm's intellectual property practice and sits on its Executive Committee (firm bio; Chambers USA). His patent work spans electrical and mechanical technologies — he is a trained mechanical engineer — with noted depth in medical devices, life sciences, wearables, and standard-essential patent disputes, including the Wi-Fi SEP litigation that produced the Federal Circuit's 2014 Ericsson v. D-Link decision, in which he was quoted as the firm's IP group co-leader (Law360). He also handles trade secrets and false advertising matters. The tracked case data reflects a strongly defense-oriented practice: his single tracked appearance is as lead counsel for defendant Samsung in Omni MedSci, Inc. v. Samsung Electronics Co., Ltd. et al. (E.D. Tex.), and his broader docket is dominated by defense of operating companies (Samsung, Intel, Alcon, Siemens, Boeing, Carlisle, Abbott, C.R. Bard) rather than NPE-side work.

LoCascio has spent his career at Kirkland & Ellis (no prior firm identified in available sources), first-chairing trials since his 30s (Law360, 2010). Verified notable results include a $52.3M jury verdict for Siemens against Saint-Gobain over PET-scanner crystals (D. Del., 2008); lead trial counsel in the Equal v. Splenda false advertising case; defense of Intel and its customers in the Ericsson v. D-Link SEP appeal; a jury defense verdict for Carlisle against Graco in Delaware (2024); and a complete defense verdict for Abbott in a California consumer class action (named to Bloomberg Law's "Unrivaled" list, 2026). The tracked Omni MedSci v. Samsung matter — an E.D. Tex. suit over wearable health-sensing patents targeting Galaxy Watch/Ring products — was voluntarily dismissed without prejudice roughly six weeks after filing (June 2025), with Samsung separately petitioning for IPRs against the same patent family.

PTAB / IPR: Yes — LoCascio appears regularly before the PTAB (Chambers notes he is "regularly appearing before district courts and in the PTAB"), including arguing the Alcon IPR2021-00835 oral hearing as petitioner's counsel and appearing in the Kapsch TrafficCom IPR2015-00808 proceedings. His bio also notes appearances before the ITC and Federal Circuit.

Bar / education: Admitted in Virginia (1995) and D.C. (1996); registered before the USPTO. J.D., Notre Dame Law School (1995, cum laude; Managing Editor, Notre Dame Law Review); B.S. Mechanical Engineering, Virginia Tech (1992).
