Stinson

Stinson LLP operates as a full-service firm with a significant presence across the Midwest, including offices in Colorado, Kansas, Minnesota, Missouri (headquartered in Kansas City), Nebraska, and North Dakota, alongside additional locations in Arizona, Washington D.C., New York, and Texas. The firm comprises nearly 500 attorneys and is recognized by Law360 as a top firm with 251 to 600 attorneys. Chambers USA also acknowledges Stinson LLP, recognizing several of its practice areas and attorneys in its 2025 rankings.

The firm's patent litigation practice handles a diverse range of technologies, from complex, multi-party industry battles to more focused disputes. Stinson's attorneys possess scientific and technical proficiency across various fields, including mechanical devices, software, computer systems (e.g., AI, machine learning), biotechnology, chemical processes, pharmaceuticals, medical devices, semiconductors, and wireless standards. Their experience extends to both enforcing and defending patent rights for a broad client base, from startups to multinational corporations.

Stinson LLP demonstrates a balanced approach in patent litigation, representing both plaintiffs and defendants. In tracked cases, the firm has appeared twice on the plaintiff side and once for the defendant. Notably, Stinson represented Rare Breed Triggers, Inc. and ABC IP, LLC as plaintiffs in patent infringement actions concerning forced reset triggers, including RARE BREED TRIGGERS, INC. et al. v. PEAK TACTICAL LLC. In this case, the plaintiffs' motion for a temporary restraining order and preliminary injunction was denied in February 2026, allowing the defendant to continue sales. Conversely, Stinson acted as lead counsel for KE Arms, LLC in ABC IP, LLC et al. v. KE ARMS, LLC et al., where KE Arms successfully defeated most claims by jury verdict and dismissal by February 2025.

The firm possesses a notable post-grant review practice before the Patent Trial and Appeal Board (PTAB), with over 20 attorneys and patent agents admitted to practice there. Stinson attorneys are experienced in both challenging patent validity as petitioners and defending patent owners' rights in Inter Partes Review (IPR), Post-Grant Review (PGR), and Covered Business Method (CBM) proceedings. Key partners in the firm's IP litigation practice include B. Scott Eidson, who has been involved in significant patent cases, and Michael A. Fleck, who served as lead counsel in a successful defense. Joel Leviton co-chairs the Intellectual Property & Technology Practice Division, and John R. Schroeder is recognized for his skill in PTAB proceedings and Federal Circuit appeals. David R. Barnard is also recognized as a Patent Star by Managing IP.
