The ruling follows a controversial Bud Light ad that aireded during the Super Bowl that shamed Coors Light and Miller Lite.

A U.S. court late Friday barred Anheuser-Busch Cos. LLC, the maker of Bud Light, from using marketing that suggests rival MillerCoors uses corn syrup in the final production of its light beers.

In his ruling, Federal court judge William Conley of the Western District of Wisconsin said Anheuser-Busch had hoped to exploit confusion surrounding the use of corn syrup in beer production, and that “consumers would interpret advertising statements about ‘made with corn syrup’ or ‘brewed with corn syrup’ as corn syrup actually being in the final products.”

MillerCoors is the U.S. division of Denver-based Molson Coors Brewing Co. (NYSE: TAP).

The ruling follows a controversial one-minute Bud Light commercial aired during the Super Bowl that shamed MillerCoors for its Miller Lite and Coors Light brews containing corn syrup.
