Stone Brewing sues MillerCoors for calling Keystone beer 'Stone'

“Keystone’s rebranding is no accident,” Dominic Engels, chief executive of Stone Brewing, said in a statement. “MillerCoors tried to register our name years ago and was rejected. Now its marketing team is making 30-pack boxes stacked high with nothing but the word ‘Stone’ visible. Same for Keystone’s social media, which almost uniformly has dropped the ‘Key.’ We will not stand for this kind of overtly and aggressively deceptive advertising.”
