Concurrent use proceeding

A concurrent use registration, in United States trademark law, is a federal trademark registration of the same trademark to two or more unrelated parties, with each party having a registration limited to a distinct geographic area. Such a registration is achieved by filing a concurrent use application (or by converting an existing application to a concurrent use application) and then prevailing in a concurrent use proceeding before the Trademark Trial and Appeal Board ("TTAB"), which is a judicial body within the United States Patent and Trademark Office ("USPTO"). A concurrent use application may be filed with respect to a trademark which is already registered or otherwise in use by another party, but may be allowed to go forward based on the assertion that the existing use can co-exist with the new registration without causing consumer confusion.

Such registrations are most commonly achieved by agreement of the parties involved, although the USPTO must still determine that no confusion will be caused.

The authority of the USPTO to issue a concurrent use registration is set forth in the Lanham Act, section 2 (d), enacted in 1947 and coded at 15 U.S.C. § 1052, which states in relevant part:
