The NHL's Utah franchise is facing another trademark challenge to its team name.

Mammoth Hockey LLC, a hockey equipment bag manufacturer based in Portland, Oregon, has filed a motion for a preliminary injunction in U.S. District Court in Utah to "protect its long-established brand against use by the NHL's new Utah franchise, which adopted the name 'Utah Mammoth' on May 7, 2025."

This motion, filed on Sept. 25, is a counter-claim against the Utah Mammoth 's owners. Uyte and Smith Entertainment Group Hockey filed a motion on Aug. 1 to end any trademark dispute with Mammoth Hockey LLC, which they said had made threats of litigation since the NHL team was officially named. That included a cease and desist letter.
