This lawsuit really rests on whether some lawyers can prove Americans are dumb enough to confuse dog treats for bacon.
Hormel has been selling a type of bacon with the brand name "Black Label" since 1963. But back in January of this year, Purina created a line of Beggin' Strips for dogs that LOOK like bacon called Black Label . . . and the packaging looks kind of similar.
So Hormel just SUED Purina for trademark infringement . . . because they're afraid people will confuse dog treats for bacon and vice versa. They want the dog treats off shelves AND for Purina to pay them for, quote, "irreparable harm and injury". (Consumerist)
