Subject: Professional Summary: Fox Rothschild LLP Patent Litigation Practice

Firm Overview

Fox Rothschild LLP is a national, full-service law firm founded in Philadelphia in 1907. Now headquartered in Philadelphia, the firm has grown to include approximately 1,000 attorneys across 30 offices in the United States. As a large, general practice firm, it is regularly ranked in the Am Law 100 and the Vault Law 100. Its litigation department, comprising over 400 attorneys, has been recognized by BTI Consulting as an "Intimidating Opponent." The firm's intellectual property group includes over 70 attorneys and registered patent agents.

IP Litigation Specialty & Side Preference

The firm's intellectual property practice describes a broad range of technical specialties, including biotechnology, life sciences, electronics, software, and consumer products. Many of its patent attorneys and agents hold advanced technical degrees and have prior industry or USPTO experience. Chambers and Partners recognizes the firm's IP practice, particularly noting its work for life sciences clients in patent prosecution and litigation. The firm's public representations highlight a significant practice in Hatch-Waxman (ANDA) litigation for pharmaceutical clients. The authoritative case data, however, shows a single tracked appearance on the plaintiff side, acting as local counsel for Neomedia Technologies, Inc. in a case against Symbol Technologies. While this limited data points to plaintiff-side work, the firm's broader marketing and representative cases indicate a practice that serves both plaintiffs and defendants.

Notable Cases & PTAB Practice

The most prominent tracked case is Neomedia Technologies, Inc. v. Symbol Technologies, Inc., where partners Charles N. Quinn and Constantine G. Loudas served as local counsel for the plaintiff. Beyond this, the firm's public disclosures point to a varied docket. Fox Rothschild highlights its success in ANDA litigation for generic and brand-name pharmaceutical companies, securing favorable settlements and judgments. The firm also has an active post-grant practice before the Patent Trial and Appeal Board (PTAB). In a notable 2024 outcome, the firm successfully defended two gene therapy patents for its client San Rocco Therapeutics against an inter partes review (IPR) petition filed by bluebird bio Inc., with the PTAB finding none of the challenged claims unpatentable. The firm also represents clients in Section 337 investigations before the International Trade Commission (ITC).

Key Partners

The firm's IP litigation practice is led by a team of experienced partners. Key contacts for the practice featured on the firm's website include New York partner Wanda D. French-Brown and Washington, D.C. partner Jeff E. Schwartz. The firm's broader intellectual property group includes numerous attorneys recognized as "IP Stars" by Managing Intellectual Property and ranked by Chambers USA, such as Gerard P. Norton in New Jersey and Gregory A. Nelson in Florida.
