Apple has been awarded a trademark for the phrase, "There's an app for that." The tagline has been used to promote the App Store and iOS devices almost since their inception, and has really caught on. From tech articles to jokes told around the water cooler, many people have adopted the phrase.
The trademark, which Apple filed for on December 4th, 2009, covers "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."
Congratulations to both Apple for their new trademark, and to me for avoiding a lame "there's an app for that" joke.
