NHL franchise Utah Mammoth fires back at trademark lawsuit

Utah鈥檚 NHL franchise says it鈥檚 spent a 鈥渃onservative鈥 $7 million to launch its branding 鈥 from over $5 million on initial and incoming merchandise to $400,000 in player jerseys and gear; from $250,000 to develop digital graphics for its broadcasts to , has learned.

And fans from Utah to New York have embraced the Utah Mammoth, from tattooing to ringing up $500,000 in merchandise as of the end of September, according to team CFO John Larson.

Immediately dropping 鈥淯tah Mammoth鈥 and the mammoth head logo 鈥 as an Oregon hockey bag maker is demanding 鈥 would destroy the valuable 鈥済oodwill鈥 the team has built, Larson said in newly filed court documents, estimating that recognition and reputation are worth 鈥渋n excess of $100,000,000.鈥

And beyond that, the franchise argues, 鈥淚t is implausible the team would recover from having to adopt a new identity.鈥

The a lawsuit against Mammoth Hockey LLC, sellers of 鈥渉igh-end hockey bags,鈥 in October, asking a judge to determine that the team鈥檚 branding did not infringe on the company鈥檚 rights. The company has since asked a Utah federal judge for an injunction ordering the Utah Mammoth to halt using the name and logo.

In its opposition to an injunction, filed Thursday in Utah鈥檚 U.S. District Court, the hockey club called the lawsuit 鈥渕isguided鈥 and 鈥渋nflammatory,鈥 saying it would 鈥渟imply not [be] possible at this point鈥 to start over, citing widespread use of its marks.

The lost $7 million in costs also would be 鈥渕agnified by the losses its licensees, sponsors and others would suffer,鈥 the team responded.

鈥淭he effort [the Utah Mammoth] and others would have to undertake to comply with an injunction, from recalling goods, erasing all digital uses of Utah Mammoth marks, removing signs at the team鈥檚 practice facility and at Delta Center, and repainting the team鈥檚 rinks,鈥 it said, 鈥渨ould be extraordinarily burdensome.鈥

Larson said his estimate of the goodwill created by the team鈥檚 branding was 鈥渂ased on, among other things,鈥 a valuation of the team by Sportico, a media company. It as of Oct. 1, 2025, which Larson noted was 鈥渁 $440,000,000 increase鈥 from the $1 billion purchase price in the spring of 2024.

But the crux of the hockey club鈥檚 defense rests on what it argues is the dissimilarity between the Utah Mammoth and 鈥淢ammoth Hockey LLC鈥 brands.

The Mammoth Hockey company, , said its customers have been confused when trying to buy their bags and have instead landed on Utah Mammoth merchandise.

But the NHL team said it鈥檚 skeptical of that argument. A market study that used 鈥済old standard鈥 methodology, surveying probable consumers of the products, showed that 0.7 percent of respondents were confused, it said in court documents鈥攁 鈥減ercentage so low it is compelling evidence confusion is unlikely.鈥

The geographic delineation, using the term 鈥淯tah,鈥 and other factors also separate the two logos, the team said.

The Utah Mammoth also fired back on the company鈥檚 assertions that team leaders 鈥渉id their intentions鈥 to use the name and logo.

In contrast, the team argues the Oregon company purposefully delayed bringing its claims until the start of the NHL season to maximize exposure. It also claims the bag company originally had no problems with the NHL team鈥檚 name, as it was being considered publicly, and fans voted on a name.

鈥淚n June 2025, [the company] first voiced its purported objection. It then delayed nearly two more months after this suit was initiated to file this motion [for an injunction], knowing the NHL season was imminent,鈥 the team鈥檚 attorneys wrote. The bag company鈥檚 鈥減rolonged delay in seeking urgent relief is inconsistent with its claims of irreparable harm.鈥

The team argues that the company and its owner, Erik Olson, initially expressed being in favor of its new name, in a June 2024 Facebook post and, more recently, in an April 2025 message.

鈥淚t would be cool to talk about a possible collaboration,鈥 Olson wrote to the team, according to court documents. 鈥淔or example, it could be a good marketing story for the Utah team to tell if we produced the team bags.鈥

Team president Chris Armstrong told his assistant, Rachel Moffitt, to respond to Olson that the franchise 鈥渨ill definitely keep this partnership in mind,鈥 court documents said.

Other companies voiced concerns during the team鈥檚 naming process, Armstrong noted, which led the Utah Mammoth to nix several options, including the Yeti, the presumptive frontrunner.

But Mammoth Hockey LLC never objected, he said.

And with other 鈥淢ammoths鈥 using the name and mammoth images in sports and on bags across the country, he said: 鈥淲e believed then and believe now that there is ample room in the marketplace for all of these users of 鈥榤ammoth鈥 trademarks to coexist without causing any harm to anyone鈥檚 business.鈥
