Overview

Calfee’s Intellectual Property litigators work with clients to protect their investments in ideas. Serving a broad spectrum of public and privately held companies, our attorneys represent plaintiffs and defendants with respect to patent, copyright, trade secret, trademark, trade dress, product configuration, unfair competition, and licensing claims.

Our attorneys focus on all major scientific disciplines including mechanical, electrical and chemical engineering; chemistry; biotechnology; computer hardware, software and circuit design; semiconductors; and architecture.

The litigators in our Intellectual Property group have gained extensive and valuable intellectual property litigation experience dating back to the 1980s when the group was formed. At any time, Calfee has 20+ attorneys devoting all or a substantial amount of their time to intellectual property litigation. Calfee’s IP litigators also are supported by and can draw upon the sophisticated case management technology and personnel of Calfee’s extensive general litigation practice if needed.

Our Intellectual Property litigators have represented clients in matters before the USPTO, federal and state courts in many of the 50 states, as well as matters involving the U.S. Customs Office, International Trade Commission and Federal Trade Commission. Our attorneys have briefed and argued cases to the Court of Appeals for the Federal Circuit and other appellate courts. Many of these matters were for clients whose patent or trademark portfolio also is maintained by Calfee. 

Additionally, understanding that intellectual property litigation can be very expensive, the litigators in our Intellectual Property group advise our clients as to the full range of alternatives for resolving intellectual property disputes including licensing, cross-licensing or joint venture negotiations, specialized proceedings in the USPTO called “IPRs,” alternative dispute resolution proceedings, and litigation in federal and state courts.
