The maker of Jack Daniel’s has sued the distiller and distributor of a cheaper, rival Tennessee sour mash whiskey, claiming it designed its label and bottle to look deceptively similar to the iconic Jack Daniel’s “Old No. 7″ design.

Lawyers for Jack Daniel’s Properties Inc., which makes the nation’s best-selling whiskey, filed a trademark and trade dress lawsuit in the U.S. District Court for the Northern District of California on April 20 against the makers of Lonehand Whiskey.
