Minnetonka Moccasin Inc. has sued Target Corp. for allegedly selling replicas that copy the moccasin maker's beaded thunderbird design.

According to the Minneapolis Star Tribune, the suit alleges that Target in early 2012 began selling the replicas after trying unsuccessfully to get Minnetonka Moccasin products into its stores.

Minnetonka claims Target's shoe are confusingly similar and would create the impression that Target's shoe is associated with Minnetonka Moccasin. It said it has used the thunderbird design for more than 40 years and has continuously and prominently displayed the design on its moccasins, according to the suit.

E.S. Originals Inc., a New York footwear supplier for Target, is also being sued.
