This legal action follows a cease-and-desist letter sent by Mammoth Hockey shortly after the Utah Mammoth unveiled its new name and logo in May 2025, citing potential consumer confusion due to branding similarities.

Both organizations utilize a mammoth design in their logos and operate within the same industry, increasing the risk of brand overlap as the Utah Mammoth enters its second NHL season.

The Utah Mammoth, an NHL team, has initiated a federal lawsuit against Mammoth Hockey LLC, an Oregon-based hockey equipment company, over a trademark dispute concerning the name 'Mammoth.'

Represented by Smith Entertainment Group, the Utah Mammoth asserts its legal right to use the name under federal and state law, claiming that it will not harm Mammoth Hockey's business.

The lawsuit was filed in U.S. District Court in Utah after negotiations between the two parties reached a stalemate regarding trademark rights.

Mammoth Hockey, established in 2014 and specializing in large hockey equipment bags, intends to vigorously defend its trademark rights against the lawsuit.

Interestingly, Mammoth Hockey had previously reached out to the Utah Mammoth's president in April 2025 for a potential collaboration but shifted its position after the team officially adopted its name.

The naming process for the Utah Mammoth was community-driven, culminating in the final name selection through four rounds of voting in May 2025.

Utah Mammoth captain Clayton Keller has expressed the team's ambition to make the playoffs in the upcoming 2025-26 NHL season, building on a successful first year where they accumulated 90 points.

Keller also conveyed confidence in the team's potential, emphasizing their experience and readiness to improve in the next season.
