Stone Brewing Sues MillerCoors Over “Stone” Trademark

San Diego – On Monday, February 12th, 2018, San Diego based Stone Brewing filed a lawsuit against MillerCoors for allegedly infringing the “Stone” trademark. According to Stone Brewing, during the rebranding of Keystone, MillerCoors has used the “Stone” trademark to potentially steal the customers and reputation of Stone Brewing.

Last April, the new Keystone cans were introduced with the word “Stone” standing out in capital letters. Later, Stone Brewing’s Greg Koch stated that MillerCoors was “deliberately creating confusion in the marketplace.” Koch continued to say MillerCoors was not only jeopardizing Stone Brewing’s reputation in the marketplace and confusing consumers.

MillerCoors has denied all allegations and called them a “clever publicity stunt,” and claims Keystone consumers have used the word “Stone” as a reference to the beer since its debut in 1989. Stone Brewing was not founded until 1996. Although according to Stone Brewing, MillerCoors tried to register “Stone” with the U.S. Patent and Trademark office in 2007 but was unsuccessful because Stone Brewing had registered in 1998.

Greg Koch released a video stating that large beer companies have been scheming against craft breweries in an attempt to counteract a decline in sales by buying out smaller companies, but knowing Stone Brewing would not sell, instead tried to steal the brand. Koch has also been responding to the mass amounts of Tweets on the matter by reiterating that Stone Brewing will not be backing down from the fight.

Lizzie Younkin, Stone Brewing’s spokeswoman, has declined any interviews about the lawsuit and stated that their lawyers will be doing to talking, while they focus on “brewing great beer.” According to IRI Worldwide, retail data showed both companies were up in sales during a 52-week period that ended January 28, 2018. Stone Brewing increased 20 percent while Keystone Light increased 12.1 percent.

Stone Brewing is calling out MillerCoors’ social media campaign, saying Facebook, Instagram and ESPN ads showed proof that Keystone is being referred to as “Stone” and has purposely placed the can so only the word “Stone” is visible in the graphic images. Stone Brewing is requesting the court to stop MillerCoors use of the “Stone” trademark in sales and distributing Keystone beer, as well as damages and the profits.
