Noted Intellectual Property Litigator Eric C. Cohen Joins Brinks Gilson & Lione
November 02, 2015

CHICAGO—Intellectual property law firm Brinks Gilson & Lione announced today that Eric C. Cohen, a deeply experienced and highly respected litigator in patent, trademark and copyright matters, has joined Brinks in its Chicago office.

For more than 35 years Cohen has focused on patent, trademark, and copyright infringement and invalidity actions in the federal courts and before the U.S. International Trade Commission and the United States Patent and Trademark Office's Patent Trial and Appeal Board (PTAB). He represents clients with innovations in the telecommunications, electronics, computer software, chemical, and pharmaceutical industries.

Notably, Cohen won one of the first inter partes review proceedings before the PTAB, which found that all of the disputed claims related to a zoomable web browser for smartphones were unpatentable. Cohen argued the appeal and obtained a per curiam affirmance by the Federal Circuit the day after the argument.

“Eric Cohen brings an outstanding track record in IP litigation to Brinks, and he presents another compelling resource for Brinks’ clients to rely on in high-stakes cases,” said James R. Sobieraj, Brinks’ president. “Client demand for our services has remained encouragingly robust this year, and we will continue to explore strategic opportunities to enhance our team.”

Cohen is the twelfth attorney hired by Brinks since August this year. He previously was with a large, general practice firm in Chicago, and following the return of patent litigator Mark H. Remus to Brinks in September, Cohen is the second attorney to join Brinks from a Chicago-based general practice firm in as many months.

“Brinks has a stellar reputation and is a much better platform for my practice,” Cohen said. “The firm has an incredibly deep talent pool that compares favorably to the top firms in the country.”

"I've known Eric for many years. He's smart, a strategic thinker, and a great guy," said Gary M. Ropski, a Brinks shareholder and former president of the firm. "I'm delighted that he and I will be practicing at Brinks at the same time. His attitude and demeanor will fit our firm perfectly."

Cohen has represented trademark and copyright owners in cases involving claims of product counterfeiting, and obtained a significant number of ex parte orders directing federal marshals to seize counterfeit goods and documents evidencing their manufacture and sale. He is also experienced with complex copyright cases relating to the scope of protection of software.

As an active member of the intellectual property legal community, Cohen lectures and writes frequently, and has presented at the Federal Circuit Bar Association, the Intellectual Property Owners Association, and the Practising  Law Institute, among others. He currently serves on the board of directors of the Federal Circuit Bar Association, and has been consistently recognized in client and peer rankings, including the Leading Lawyers Network, Illinois Super Lawyers, and Managing Intellectual Property's IP Stars. Cohen graduated cum laude from the University of Miami School of Law, and holds a degree in physics from Case Western Reserve University.
