Patent Litigation


Patent lawsuits are both expensive and threatening to the viability of a business. Whether an enterprise is the victim of patent infringement or the target of allegations concerning infringement, it will require patent litigation attorneys with the expertise and experience to handle the most complex patent infringement lawsuits involving a wide variety of technologies and scientific processes.

The intellectual property attorneys in Ulmer & Berne’s patent litigation practice have backgrounds in a variety of technical disciplines, and a clear understanding of how to successfully and efficiently counsel clients as to effective management of patent-related disputes. Prior to their legal careers, many of our litigators gained experience in sectors of the engineering industry (including electrical, mechanical, chemical and software) as well as computer science and other technology-based fields. Many of these attorneys are registered with the U.S. Patent and Trademark Office (USPTO).

Clients also need advice from attorneys who know patent law and have proven themselves as first-rate trial counsel. We represent clients in federal court, as well as before the USPTO and International Trade Commission (ITC) proceedings. We manage all phases of the patent litigation process. Our combination of deep technical expertise and wide litigation experience offers clients the best of both worlds and the best opportunity for success.
