Deeply experienced and highly respected by peers and his clients, Eric C. Cohen is an accomplished patent, trademark and copyright attorney who focuses on litigation.

For more than 35 years, Cohen has argued patent, trademark, and copyright infringement cases 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.

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.

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.

An active member of the intellectual property legal community, Cohen lectures and writes frequently. He has presented at the Federal Circuit Bar Association, where he is on the Board of Directors, at the Intellectual Property Owners Association, and at the Practicing Law Institute, among others. He is consistently recognized in client and peer rankings, including the Leading Lawyers Network, Illinois Super Lawyers, and Managing Intellectual Property's IP Stars.
