The Utah Mammoth have filed a lawsuit against the hockey equipment brand "Mammoth Hockey." The lawsuit is largely centered around the use of the name after the Mammoth selected their team name earlier this year.

The Smith Entertainment Group (SEG) filed the federal lawsuit on August 1 and requested that the court find “that their use of the ‘Utah Mammoth’ trademark is fully compliant with relevant federal and state law, and not violative of any trademark rights defendant may possess.”

Mammoth Hockey had previously sent a cease-and-desist letter to SEG on June 10, requesting that the team stop using the name "Mammoth."

"Your use of the name ‘Utah Mammoth’ in connection with hockey-related goods is highly likely to confuse consumers into thinking that your company is somehow related to or endorsed, licensed, sponsored, or otherwise associated with Mammoth Hockey,” the letter stated. “Such confusion risks the appropriation of the mark’s goodwill that Mammoth Hockey has built up in the mark for more than 10 years.”

SEG provided a statement to Deseret News on August 5 regarding the lawsuit.

“The Utah Mammoth filed an action in the U.S. District Court for the District of Utah seeking a declaratory judgment that use of the trademark Utah Mammoth does not violate any rights asserted by a third party.

“Utah Mammoth and the NHL believe strongly that we have the right to use the name Utah Mammoth under federal and state law, and that our use will not harm the defendant or its business in any way. We have taken this action only after careful consideration based on the defendant’s position. We are not able to comment further on ongoing legal matters.”
