DENVER, Aug. 15, 2013 /PRNewswire/ -- CoBank has filed a formal notice of opposition with the U.S. Patent & Trademark Office against a trademark application by Green Dot (NYSE: GDOT) for Green Dot's new "GoBank" bank account service. The notice of opposition states that CoBank is the owner of various well-established trademarks incorporating the "CoBank" name and has been doing business using those marks since 1989. The notice states that Green Dot's recent application to register the "GoBank" service "is likely to cause confusion, or to cause mistake, or to deceive, particularly as to the source or origin of the goods and services with which Applicant uses its mark, to induce purchasers to believe that the goods and services of Applicant are those of Opposer, or are endorsed by, or are in some way affiliated or associated with Opposer." CoBank is requesting that the U.S. Patent & Trademark Office's Trademark Trial and Appeal Board deny Green Dot's application for registration of the "GoBank" mark.
