While Lidl announced the opening of seven more July store openings in the United States, the German-based discount retailer is facing some pressure from an American giant.

Kroger, the nation’s largest supermarket chain, is suing Lidl over the former’s Preferred Selection private label. Kroger says it is too similar to its own Private Selection label.

The lawsuit was file on June 30 and says Lidl is attempting to benefit by “causing confusion” between its brand the Kroger’s. It also says that Lidl’s label “dilutes” Kroger’s store band. Lidl’s Preferred Selection brand was registered in September of last year.

The suit claims that Lidl has competed unfairly with Kroger and that “Kroger has suffered and will continue to suffer irreparable injury, including, but not limited to, injury to its trademarks and to the goodwill and business reputation associated with those trademarks.”

Kroger is seeking compensation from all profits from Lidl’s Preferred Selection brand.
