Cincinnati, OH-based grocery retailer Kroger Company (NYSE:KR) recently filed a trademark infringement suit against German-based discount supermarket chain Lidl over a private food label. The suit, filed in the U.S. District Court for the Eastern District of Virginia (E.D. Va.), alleges both trademark and service mark infringement and is seeking to have a related U.S. trademark application filed by Lidl cancelled. The suit comes just weeks after Lidl opened its first locations in the United States.
