Matthew Duescher — Patent Litigation Practice Summary

Specialty and focus. Matthew Duescher (Matthew N. Duescher) is a counsel-level IP litigator at Foster Murphy Altman & Nickel, PC, a Washington, DC boutique known for ITC Section 337 and patent work. His practice is centered on Section 337 investigations before the U.S. International Trade Commission and matters before U.S. Customs and Border Protection, where Chambers USA ranks him "Up and Coming" (International Trade: IP, Section 337). He has participated in 20+ Section 337 investigations spanning semiconductors, consumer products, pharmaceuticals, and warehouse automation systems, plus trademark and trade-secret claims. His physics background (BS, Carnegie Mellon) fits his technical docket, though his matters also reach into medical devices and pharma.

Side preference and firm context. His tracked appearances are entirely defendant-side (1 of 1), and his verifiable ITC work also comes as respondent's counsel — e.g., representing UK respondent Printed Motor Works Ltd. in Certain Automated Storage and Retrieval Systems (Inv. No. 337-TA-1228). He has spent his career at Foster Murphy, where he joined after clerking at the ITC's Office of Unfair Import Investigations and for an ITC administrative law judge while in law school.

Notable cases and outcomes. The tracked matter is HydraFacial LLC v. Sinclair Pharma Limited et al. (C.D. Cal., No. 2:24-cv-06250), a hydrodermabrasion/medical-device patent suit in which Duescher appeared for defendants; the case was stayed and administratively closed in April 2025 for mediation, with no merits ruling. His most prominent verifiable result is the AutoStore v. Ocado investigation (337-TA-1228), where the ITC affirmed a no-violation finding — the asserted claims were held invalid for written-description/enablement deficiencies and not infringed — a complete defense win for his respondent clients.

PTAB/IPR and credentials. His practice is district-court/ITC-focused, and I found no verified record of him personally appearing in IPR/PGR proceedings, though the HydraFacial dispute spawned a parallel PTAB petition (IPR2025-00145) filed by Sinclair Pharma. Bar/education: admitted in the District of Columbia (2016); JD, George Mason University School of Law (2015); BS in Physics, Carnegie Mellon University (2011) — per Chambers and Super Lawyers profiles.
