National Distillers Products Co. was founded to market and sell a vodka called Teton Glacier, and the company registered this mark with the U.S. Patent and Trademark Office. National Distillers sought to market the product as an ultra-premium vodka, but it was not very successful. Within a year, Refreshment Brands, Inc. (RBI), began advertising that it would be selling a new vodka product called Glacier Bay. After RBI produced the product, National Distillers sued for trademark infringement. Should the plaintiff prevail?
