This case arose from a well-known Bud Light advertising campaign launched during the 2019 Super Bowl, including a 60-second commercial, titled "Special Delivery," as well as two 15-second commercials, "Medieval Barbers" and "Trojan Horse Occupants," which focused on the use of corn syrup in the brewing of competitor Miller Lite and Coors Light beers. The "Special Delivery" ad, for instance, featured a fictional Bud Light kingdom, where, as the Bud Light King explained to his subjects, Bud Light beer is brewed with water, rice, hops, and barley. When a barrel of corn syrup is delivered, the king declares that Bud Light is not brewed with corn syrup and orders his knight to deliver the barrel to the Miller Lite and Coors Lite kingdoms, where beer is brewed with corn syrup. Anheuser-Busch extensively disseminated its "no corn syrup" campaign after the Super Bowl, running several additional television commercials, including two broadcast during the 2019 Oscars, a Twitter and print-media campaign, as well as billboards stating that Bud Light had "100% less corn syrup" than Coors Light and Miller Lite. See MillerCoors, LLC v. Anheuser-Busch Cos., 385 F. Supp. 3d 730 (W.D. Wis. 2019).
Molson Coors (originally filed by related entity MillerCoors LLC) sued Anheuser-Busch for false advertising under the Lanham Act, arguing that while it uses corn syrup as an ingredient in brewing Miller Lite and Coors Light, the advertising misleadingly suggested corn syrup was actually in the final beer product. Accordingly, the dispute centered on the distinction between Miller Lite and Coors Light's acknowledged use of corn syrup as the aid to fermentation in brewing their beers, and the alleged false message that there is actually corn syrup in the beer that consumers ultimately drink.
The Seventh Circuit (as do others) recognizes two categories of false advertising under the Lanham Act: statements that are literally false and statements that are true but misleading. Eli Lilly & Co. v. Arla Foods, Inc., 893 F.3d 375, 381-82 (7th Cir. 2018). The district court in the Western District of Wisconsin found that Anheuser-Busch's advertising was not literally false - the ads truthfully stated that Miller Lite and Coors Light are "made with," "brewed with" or "use" corn syrup. But the court granted a preliminary injunction to bar Anheuser-Busch from making purported misleading statements that suggested to consumers that corn syrup was in Miller Lite and Coors Light beer, later modifying that injunction to also bar statements on Anheuser-Busch's own packaging that Bud Light beer had "no corn syrup."
