Dentons’ Patent Litigation Group handles complex disputes for and against many of the world’s largest technology companies. But we also represent inventors and small companies seeking to enforce or defend against patent claims. Likewise, we represent nontechnology companies faced with patent controversies, often unrelated to their primary line of business. Our clients range from the largest to the smallest, from the most technical to the least technical, across almost every technology area. In all matters and for all clients, we strive to define and attain your business objective.

Our core patent litigation team includes experienced trial attorneys who have mastered the law and rules of courts, and understand the intricacies of the technologies at issue. Our peers have recognized our achievements and many of us have formal educations in science and engineering. Many of our litigators have knowledge in additional areas of law, such as antitrust and appellate law, which enables us to approach cases from a different perspective and sometimes identify issues that otherwise might get overlooked.

Dentons’ size and geographic breadth allows us to assemble teams of lawyers and other professionals that combine the legal and technical know-how appropriate for each case. Such teamwork sometimes crosses international borders, enabling us to simultaneously pursue your interests in multiple countries. At the same time, our presence in key markets allows us to provide you with truly local service and advice when needed.

Client Alert: AI Enters the Courtroom—Judges Get Chatty with ChatGPT in Ross v. United States (2025)

February 27, 2025

What is common knowledge? Consider consulting ChatGPT, as the panel in Ross v. United States, a case before the District of Columbia Court of Appeals did.
