Back in 2004 The Florida Department of State trademarked Miami as the ‘"Gateway to the Americas." They also trademarked ‘Gateway of the Americas’ with the United States Patent and Trademark Office in order to prevent other cities from using the phrase.
According to published reports, the new slogan is part of the state’s drive to have Miami selected as the location for the permanent headquarters of the proposed Free Trade Area of the Americas.
