Dunkin' Donuts surely prides itself on its coffee, but is it the best in the nation?
The restaurant chain recently filed an application with the U.S. Patent and Trademark Office to trademark the phrase "Best Coffee in America," but the application was denied.
Federal officials said the slogan was not "distinctive enough to qualify for protection."
Coffee drinkers in Connecticut were mixed on the ruling.
"I personally think Dunkin' Donuts is the best coffee in the world," said a customer outside a Dunkin' Donuts in West Hartford.
In East Haven, customers disagreed.
"I think Dunkin' Donuts does make a decent cup of coffee, but I don't think it's the best in the world," said Joe Giordano.
The Massachusetts-based chain has more than 2,600 stores around the world and sells 1.5 billion cups of coffee a year. The company is considering an appeal to the rejection of its trademark application.
