RightRice, which is found on D.C.-based Cava’s fast-casual restaurant menu and sold in supermarkets nationwide, is currently branded as RightRice®, with a rice-shaped mark over the second “i” instead of a dot. The Nov. 29 decision of the U.S. Patent and Trademark Office’s Trademark Trial and Appeal Board to cancel the trademark means the symbol will have to come off, the federation states, though “rice” can remain — rice is a grain, not a trademark.
