Dunkin' Donuts offered a large claim that it serves the best brew in the country, but not everyone agrees.

The popular donut brand attempted to officially trademark the claim that they served the "Best Coffee in America," but the claim was rejected by the U.S. Patent and Trademark Office, who would not allow the company to use it exclusively to sell coffee.

The phrase would have given the company a competitive marketing advantage over their competitors.

However, the Massachusetts-based donut and coffee company could not trademark a definitive statement such as offering the "Best Coffee in America" because it is a subjective claim that does not hold the proper means to quantify the claim.

Zick Rubin, a trademark attorney in Newton, Mass., was quoted in the Boston Globe saying why the claim was rejected:

"Anyone at all can claim that their coffee is the 'Best Coffee in America.' No one takes such a claim literally, and no one company can monopolize the phrase."

The United States Patent and Trademark Office stated their decision in a letter to Dunkin' Donuts, saying that the mark of "Best Coffee in America" is "merely descriptive - Incapable of registration on Principal Register."

The government office continued to state the following: "Registration is refused because the applied-for mark is merely laudatory and descriptive of the alleged merit of applicant's services and the goods featured therein."

According to WebProNews, Dunkin' Donuts spokesperson Jessica E. Gioglio commented, "As a company with a more than 60-year heritage that is proud to be an American icon, Dunkin' Donuts sells more than 1.5 billion cups of hot and iced coffee globally every year. We are simply going through the trademark process."

Donkin' Donuts can still claim to sell the best coffee around, but that's up to the opinion of the consumer. The company just won't be able to have the mark of the Patent and Trademark Office to justify their claim.
