Taco John’s Sends Brewery Cease-and-Desist Over Taco Tuesday Trademark | Eater

"A fast-food chain with roughly 400 locations concentrated in the Midwest and Mountain regions that legally owns the federal trademark for the phrase “Taco Tuesday” (registered in 1989) and has aggressively enforced it with hundreds of cease-and-desist letters. The company publicly claims to have originated the concept and treats the phrase as part of its brand DNA, using the mark prominently in marketing. Legal commentators, however, consider the trademark weak and at risk of genericide given the phrase’s long, widespread use dating back decades, and historical uses and earlier state trademarks complicate the chain’s exclusive claim." - Jenny G.
