Comprehensive Capabilities

Clients rely on Ropes & Gray’s trial lawyers not only to evaluate and assert patents against infringing competitors, but also to defend against charges of infringement, no matter how or where they arise. Our teams pair a thorough understanding of complex, cutting-edge technologies with a mastery of the nuances of patent law.

  • Our professionals possess over 150 degrees in disciplines such as electrical engineering, organic and synthetic chemistry, computer science, pharmacology, biochemistry, molecular and cellular biology, neurobiology, immunology, genetics, chemical engineering, biophysics, polymer science and aerospace engineering.
  • Our deep bench of “first chair” trial lawyers and our unparalleled technical capabilities ensure that the Ropes & Gray team can communicate with the most advanced technical experts and convey that information in a clear and persuasive manner to judges and juries alike.

We draw on years of experience and training to harness these resources and manage all phases of complex litigation. Our attorneys represent companies at both the trial and appellate levels, in key patent litigation courts across the nation. We also litigate matters before the U.S. Patent and Trademark Office (PTO), the U.S. International Trade Commission (ITC) and tribunals around the world, where we work collaboratively with experienced local counsel.

Diverse Clients

Our patent litigation team of over 110 attorneys represents clients across a wide spectrum of industries, including electronics, pharmaceuticals, financial services, Internet/e-commerce, telecommunications, manufacturing and medical devices.
