Lest trademarking a croissant/donut seem absurd, there is ample precedent. Chefs, or more often, big food companies, can protect the names of their unique products -- think Boardwalk Fries, or Coca-Cola, or Big Mac. Recipes or lists of ingredients cannot be trademarked, nor can traditional dishes, like a hamburger or ramen. Still, "The Cronut® is a little bit of an unusual case," says Julian Cordero, attorney and managing member at Cordero Law LLC in New York City -- a rare, ballsy legal move, as it's usually a major corporation that takes this step, not a small, single bakery. "It's not necessarily the fact that it's a food, it's the name you provide that is important for a trademark," Cordero explains.
