WASHINGTON, Dec. 10 (UPI) -- The Norwegian manufacturers of Comfyballs underwear said the U.S. patent office told them the brand name is too "vulgar" to trademark.
Company founder Anders Selvig said officials filed an application with the U.S. Patent and Trademark Office earlier this year with an aim toward bringing the products to the North American market, but the office's reply said the name was too "vulgar" to trademark.
