In June, Gander Outdoors revealed its new logo, a G and O combined in a circle, creating a mountain peak.
Trouble is, North Face created a very similar design in 2000 for its Summit Series.
"In both designs, the lines forming the stylised mountain peaks appear to protrude from the circle at virtually the same point and angle, making both the negative and positive spaces in each design highly similar," said North Face's claim.
In August, North Face expressed its concerns to Camping World, the company owned by Marcus Lemonis that purchased the bankrupt Gander Mountain. Camping World allegedly replied with a statement that consumer confusion was unlikely. An attempt to reach Lemonis on Friday was not successful.
On Dec. 19 North Face filed suit in U.S. District Court in Delaware. It is seeking a permanent injunction against the Camping World Group, triple damages, profits and any other relief that the court may deem appropriate.
In March St. Paul-based Gander Mountain announced its bankruptcy and plans to close all 160 stores. Lemonis purchased the rights to the brand and its operating systems. Earlier this month, Gander Outdoors reopened its first renamed store in Lakeville.
