Technical Depth, Industry Breadth

Ropes & Gray’s IP litigation team consists of more than 75 attorneys and technical advisors working across offices and regions to defend and enforce our clients’ interests in patent and IP litigation. Many of our attorneys and technical advisors hold degrees in science and engineering disciplines such as electrical engineering, computer science, pharmacology, biochemistry, molecular and cellular biology, neurobiology, chemical engineering, and aerospace engineering.

Our litigation teams pair a thorough understanding of complex technologies with a mastery of the nuances of patent and IP law to represent clients across a wide spectrum of industries, including electronics, semiconductors, software, pharmaceuticals and biologics, financial services, internet and e-commerce, telecommunications, and medical devices. Many of our attorneys worked in these industries prior to joining Ropes & Gray, giving them real-world insight into the issues clients face.

A Leader in the Field

Ropes & Gray’s IP litigation trial team is consistently recognized as a leader by national and global sources, including Chambers USA, Chambers Asia, Chambers Global, Benchmark Litigation, The Legal 500, International Asset Management (IAM) and Managing IP. We were named the 2019 “Law Firm of the Year” for patent law by U.S. News & World Report-Best Lawyers, and recognized nationally by the magazine for copyright law, trademark law and intellectual property litigation. The IAM Patent 1000 Guide recognized six of our IP litigation attorneys in 2018 for their work on IP matters and in post-grant and ITC proceedings, and Managing IP named eight Ropes & Gray attorneys “IP Stars.” 

Groundbreaking Graphics Team

Establishing and protecting the value of complex technologies often requires presentation of sophisticated and subtle technical concepts to judges, juries, government agencies and investors. To simplify this challenge, we complement the work of our attorneys with an award-winning in-house graphics and animation team. Our graphics professionals create state-of-the-art 2D and 3D static and animated visual media to help Ropes & Gray litigation teams clearly convey technical testimony to judges and juries.
