Summary:

Crowell & Moring LLP is a large, international law firm headquartered in Washington, D.C., with offices across the United States, Europe, the Middle East, and Asia. As an AmLaw 100 firm with approximately 600 lawyers, it maintains a full-service practice, with intellectual property litigation being a core strength. The firm’s IP group comprises over 100 attorneys and patent agents, many with advanced technical degrees, handling complex patent disputes in district courts, at the U.S. International Trade Commission (ITC), and before the Patent Trial and Appeal Board (PTAB).

The firm's patent litigation practice has a notable emphasis on life sciences, including Hatch-Waxman and BPCIA litigation for pharmaceutical and biologics clients. Additionally, Crowell demonstrates significant experience in high-stakes litigation involving complex technologies such as semiconductors, medical devices, and robotics. The firm is particularly recognized for its ITC practice, where it handles Section 337 investigations involving unfair importation of infringing goods. According to a 2022 report, Patexia ranked Crowell among the top 20 most active and best-performing firms for ITC litigation.

The provided data indicates a plaintiff-side representation in Orthosie Systems, LLC v. SVR, LLC, and the firm has secured significant plaintiff-side verdicts. However, broader industry analysis shows a substantial defendant-side practice; a 2026 Patexia report ranked the firm 49th most active for defendants in U.S. district court patent litigation. The firm's active ITC and PTAB dockets also show robust practices representing both complainants/patent owners and respondents/petitioners. This demonstrates a balanced practice that serves both patent holders and accused infringers.

Crowell has secured multiple noteworthy public victories for its clients. In March 2026, the firm won a $48 million jury verdict for Kawasaki Heavy Industries in a patent infringement case concerning semiconductor wafer-handling technology. The firm also obtained a jury trial win for Siemens Mobility, resulting in a damages award of over $15 million. The firm's active PTAB practice, consisting of over 40 lawyers, handles a significant volume of inter partes review (IPR) and post-grant review (PGR) proceedings for clients on both the petitioner and patent owner side. Key partners in the patent litigation practice include Robert Mallin and Mark Remus, who co-led the Kawasaki trial, and Kathryn L. Clune, a co-lead of the firm's ITC Section 337 practice.
