Coca-Cola appears to have scored a partial win in its battle for dibs on the word “zero.”

Coke has tried for years to get exclusivity to use "zero" on beverages. Recently, the federal Trademark Trial and Appeal Board ruled that while Coke can register "zero" for non-calorie drinks such as Coca-Cola Zero, other makers of zero-calorie drinks also can use the word, according to a report in The Wall Street Journal.

All of which means that the word battle may not be over.
