The overall case involves Anheuser-Busch's Bud Light ad campaign that noted the use of corn syrup by MillerCoors in brewing Coors Light and Miller Lite but not by Anheuser-Busch in making Bud Light in commercials that initially aired Feb. 3 during Super Bowl LIII, along with certain later advertising. The Super Bowl ads generated significant pro and con traffic on social media and drew the ire of corn growers and the corn sweetener industry, although Anheuser-Busch maintains it did nothing to disparage corn syrup in its ads. MillerCoors filed a lawsuit on March 21, claiming false and misleading claims and misuse of Miller and Coors trademarks in a Bud Light Super Bowl commercial and in part sought an injunction to stop Anheuser-Busch from running the Bud Light ad.
