Apple's trademark filing for their famous catchphrase, "There's an App For That" has been approved by the United States Patent and Trademark Office. The patent is filed under the Advertising, Business and Retail Services, Computer and Software service and Scientific services categories.
The trademark applies to, "Retail store services featuring computer software provided via the Internet and other computer and electronic communication networks; retail store services featuring computer software for use on handheld mobile digital electronic devices and other consumer electronics."
This doesn't mean that there can't be anymore cheesy blog headlines with the catchphrase (which I have been guilty of a couple of times). It does mean that Apple can pursue a commercial infringement of the trademark with much greater ease in court...
