Jack Daniel's is locked in a trademark infringement battle with a small but up-and-coming distiller called Popcorn Sutton, which the famed Tennessee whiskey label has accused of ripping off its signature square bottle shape as well as its labeling.

The legal battle puts the famous whiskey brand up against a smaller distiller that proudly claims to carry on the tradition of the famous moonshiner Marvin "popcorn" Sutton, who wrote a book called "Me and My Likker" as well as recorded several instructional videos on making moonshine before taking his own life ot avoid jail time in 2009.

Now, the whiskey makers that he inspired are being sued by Jack Daniel's, which claims that the bottling and labeling for Popcorn Sutton's product is "confusingly similar" to the bottling and labeling for Jack Daniel's whiskey.

According to NewsMax, the suit, which was filed in Nashville, wants the Popcorn Sutton bottle removed from the market. The packaging in question reportedly hit store shelves in either late 2012 or early 2013.

"Defendants' use of the new Popcorn Sutton's trade dress in connection with their Tennessee white whiskey is likely to cause purchasers and prospective purchasers of the product to believe mistakenly that it is a new Tennessee white whiskey product in the Jack Daniel's line," the lawsuit read.

Named as defendants in the sit are J&M Concepts LLC and Popcorn Sutton Distilling LLC, which operate in Nashville. The small distillery's website lists the product as available in Tennessee, Kentucky, Arkansas and Georgia.

Jack Daniel's is the most popular brand based out of Louisville by Brown-Forman. The company sold 11 million cases of Jack Daniel's Black Label Tennessee Whiskey in the fiscal year that ended this past April. Jack Daniel's Whiskey is produced in Lynchburg, Tenn.

With the exception of a few minor and negligible tweaks, the Jack Daniel's packaging has been "a consistent commercial impression" for decades, the suit read. The packaging is "one of the oldest, longest-selling and most iconic consumer products" in U.S. history.

The lawsuit seeks an injunction to stop the defendants from using their current bottle. It also asks for unspecified damages.
