ALBUQUERQUE, N.M. (AP) – The Navajo Nation and Urban Outfitters have failed to reach a settlement in a federal lawsuit alleging trademark violations.

The tribe sued the clothing retailer and its subsidiaries last year to keep them from using the “Navajo” name or variations of it on their products.

U.S. District Judge Lorenzo Garcia in New Mexico had thrown out all deadlines for discovery and responses to motions while settlement discussions took place. The parties wrote to the court this week saying that mediation has been unsuccessful.

The parties say no other mediation sessions are planned.

Urban Outfitters argues that “Navajo” is a generic term for a style or design and has asserted counter claims. It is seeking a declaration of non-infringement and cancellation of the tribe’s federal trademark registrations.
