Intellectual Property Litigation

Overview

Unlike any other business assets, intellectual property and trade secrets can cross the globe in milliseconds. When IP disputes arise, businesses worldwide need legal resources that can respond quickly and effectively across jurisdictions.

A powerhouse, global intellectual property team

At Crowell & Moring U.K. LLP, our London-based team works closely with colleagues across the United States and in Europe, including more than 100 lawyers, patent agents, and scientific advisors in Chicago, Washington, DC, New York, Indianapolis, California, and Brussels. A number of our lawyers hold advanced degrees in key scientific and technological disciplines, including molecular biology, chemical, mechanical and electrical engineering, computer science, life sciences, and pharmaceutical science.

Crowell’s European partners are registered to practice before the European Union Intellectual Property Office, and our U.S.-based lawyers have held senior leadership positions in leading multinational corporations, as well as at the U.S. Patent and Trademark Office (USPTO). Several have served as trailblazers in the development of legislation, regulation, and oversight bodies, including the U.S. Patent Trial and Appeals Board (PTAB), that define and govern IP prosecution, protection, and dispute-resolution processes.

Firm litigators practice before courts worldwide, including the U.S. Court of Appeals for the Federal Circuit and virtually all other federal appellate and district courts, as well as the U.S. International Trade Commission (ITC), the Patent Trial and Appeal Board (PTAB), the Trademark Trial and Appeal Board (TTAB), the Benelux Intellectual Property Office, the Court of Justice of the European Union, and the Brussels Court of Appeals.

Broad client base, practical legal counsel

We serve a wide range of clients, from mid-market manufacturers, retailers, and entertainment and media companies, to Fortune 100 and other top corporations whose brands are household names and whose products lead the way in technological innovation.

In resolving IP disputes, our primary strategies centre on simplicity and efficiency. While the principles of IP law can be complex, disclosure must be directed toward the final goal and trial themes must be clear and persuasive. By focusing on our client’s objectives, we are able to keep litigation costs down while, at the same time, achieving success.

A New Frontier for Added Subject-Matter at the EPO?

At the European Patent Office (EPO), a recent referral of case T 873/24 from the Technical Board to the Enlarged Board of Appeal may clarify whether last summer’s decision in case G 1/24 on claim interpretation may be extended to the analysis of Added Subject-Matter. Already G 1/24 is impacting the assessment of patentability at the EPO, but should this referral be allowed, G 1/24’s effect on the assessment of added matter could result in a real shake up of the EPO’s notoriously strict assessment of support. Nonetheless, a review of how we got here highlights the value of late arguments during the EPO appeal process....
