Monte T. Squire — Patent Litigation Practice Summary

Focus areas. Squire is a Wilmington, Delaware–based IP litigator whose practice centers on patent infringement litigation in the District of Delaware and parallel USPTO proceedings, with an emphasis on serving as Delaware/local counsel. Firm and Chambers descriptions list software and internet technology, telecommunications, semiconductors, biomedical devices, life sciences and pharmaceuticals, aeronautical equipment, mobile navigation, and mechanical/solar mounting hardware among the technologies he handles. His technical background is as a chemical engineer (B.Chem.Eng., University of Delaware), and he spent roughly a decade as an R&D engineer/product manager at Lyondell Basell before law school.

Side preference. In the tracked data he appears twice, both on the defendant side for operating companies (one as lead counsel, one as counsel) — 0 plaintiff-side appearances. The public docket record is broader: aggregator data (PlainSite) shows him appearing earlier in his career for plaintiffs/patent owners as well, including Parallel Networks in a large 2012–13 Delaware campaign, Beacon Navigation, and Unirac — so his historical practice is mixed, with a current defense tilt. That earlier plaintiff-side record comes from third-party docket aggregators rather than the authoritative case list, and should be treated as indicative rather than confirmed.

Firm context. Squire has been a partner in Duane Morris LLP's Intellectual Property Practice Group in Wilmington since 2021. Before that he served six years as an Administrative Patent Judge on the PTAB (2015–2021), and prior to that was an IP and commercial litigator at Young Conaway Stargatt & Taylor (2005–2008, 2009–2015). He began his career clerking for Judge Gregory M. Sleet on the U.S. District Court for the District of Delaware. He is a past chair of the Delaware State Bar Association's Multicultural Judges and Lawyers Section, serves on the District of Delaware's Lawyers Advisory Committee, and was appointed a Special Master for that court.

Notable cases and outcomes. The most prominent tracked matter is Proxense, LLC v. Apple Inc. (W.D. Tex.; related IPRs), where he has acted for Apple. He argued the PTAB hearings in Apple v. Proxense, IPR2024-00232/‑00233 (patents 8,352,730 and 8,886,954), leading Apple's challenge to Proxense's biometric-authentication patents; Proxense requested adverse judgment on the '730 claims. In the joined Microsoft/Apple proceeding IPR2024-00573, the Board issued a final written decision on August 4, 2025 holding all challenged claims of U.S. Patent 8,646,042 unpatentable. Proxense's appeal of the related IPRs was docketed at the Federal Circuit (No. 25‑2168, filed Sept. 30, 2025); no outcome is yet reported. He has also appeared for Duane Morris client SonicWall in DataCloud Technologies v. SonicWall (D. Del.), and the firm lists his representation of Unirac in its solar-mounting patent suits against EcoFasten/Esdec, where the court's July 2022 claim construction largely tracked Unirac's positions and the cases resolved by joint stipulation of dismissal with prejudice in July 2022. One tracked matter is listed without a case name in the underlying data and cannot be independently identified here.

PTAB/IPR experience. This is a signature strength: six years as an APJ deciding IPRs, followed by regular PTAB practice as counsel. He has served as lead counsel on petitions (e.g., Infinera v. Soto, IPR2023‑00834; multiple Apple v. Proxense IPRs) and has represented patent owners in PTAB proceedings (e.g., OnPoint Systems in IPR2021‑01483).

Bar and education. Admitted in Delaware, New Jersey, and before the USPTO (Reg. No. 80,123), plus the Federal Circuit, Third Circuit, and several district courts (D. Del., E.D. Tex., N.D. Cal., D. Or.). J.D., Widener University School of Law (cum laude, 2005); M.B.A., Wilmington College (1999); B.Chem.Eng., University of Delaware (1995).
