Peter Krusiewicz — Patent Litigation Practice Summary

Focus areas. Krusiewicz is an associate in Nixon Peabody's Intellectual Property Practice Group, working on both patent litigation and prosecution. His firm bio describes prosecution experience spanning mechanical apparatus and manufacturing processes, software, and chemistry — consistent with his technical background as a mechanical engineering graduate (University of Illinois at Urbana-Champaign) and former manufacturing engineer. His litigation docket skews toward consumer-facing wearable and optical-sensor technology (physiological monitoring devices) and, separately, semiconductor/processing technology via the Network System Technologies matters, rather than pharma or standard-essential Wi-Fi litigation.

Side preference. His tracked appearances are mixed: one plaintiff-side and two defendant-side. In practice he has been most visible representing patent owners and asserting parties — Omni MedSci, Inc. in its E.D. Tex. wearable-device campaign, and Network System Technologies, LLC against Qualcomm — while also appearing on the accused-infringer side for WHOOP, Inc. In the Omni MedSci matters he is part of the Nixon Peabody team (led by partners Jennifer Hayes and Daniel Stringfield) representing the patent owner against Samsung, Fossil, Ōura, and OnePlus challenges. His role is that of a supporting associate rather than lead counsel; the pattern is defense of mid-size patent holders plus defense-side work for operating companies, not a dedicated NPE litigation shop.

Notable matters and outcomes. Tracked cases: Omni MedSci, Inc. v. Samsung Electronics Co., Ltd. (E.D. Tex. No. 2:24-cv-01070), where he entered an appearance for Omni MedSci in January 2025, and the related PTAB proceedings (Samsung Electronics Co., Ltd. v. Omni MedSci, Inc., IPR2025-01249–01254 and PGR2025-00063–64). He also appears for WHOOP, Inc. in WHOOP, Inc. v. Omni MedSci, Inc. (PGR2026-00003) and in the parallel Delaware case Omni MedSci, Inc. v. Whoop, Inc. (D. Del. No. 1:25-cv-00140); in that dispute, USPTO Director Squires found the asserted '790 patent AIA-eligible for PGR and the Board instituted WHOOP's petition (April 2026), while Samsung's competing IPR was stayed and referred to Director Review — results widely covered by Law360 in May 2026. He is also on the Nixon Peabody team representing Network System Technologies against Qualcomm, including a 2025 Unified Patent Court dispute over attorney access to confidential materials.

PTAB/IPR experience. He appears regularly in PTAB proceedings. In Network System Technologies, LLC v. Qualcomm he was admitted pro hac vice as patent owner counsel in IPR2024-00338 and IPR2024-00343, and he participated in the March 2025 oral hearing in IPR2024-00343. His March 2025 LEAP practitioner certification (three or fewer substantive oral arguments before federal tribunals, including the PTAB) indicates early-career argument experience rather than a substantial record of argued hearings.

Bar and education. Admitted in Illinois and before the U.S. District Court for the Northern District of Illinois; JD, DePaul University College of Law; BS in Mechanical Engineering, University of Illinois at Urbana-Champaign. One caution: the firm website currently lists him as an associate, while the tracked-appearance data labels his roles as "Counsel"; the firm bio is the more specific public source on title, and no prior-firm history appears in searchable public sources.
