U.S. rejects Whole Foods' trademark claim as 'World's Healthiest Grocery Store'

Whole Foods Market says it's "America's Healthiest Grocery Store."  Now, the grocery chain is looking to update its slogan to reflect a loftier moniker: "World's Healthiest Grocery Store."  Unfortunately for the grocer's efforts, the U.S. Patent and Trademark Office recently rejected its application to register that slogan. Whole Foods will have six months to update and refile the case and may choose not to do so, although that seems unlikely.
