Los Angeles - The U.S. Patent and Trademark Office announced on Tuesday that it will revoke a patent on live concert recording technology owned by Instant Live -- which was a part of Clear Channel Communications until it was spun-off along with other assets in December 2005 to form Live Nation -- following a successful challenge launched last year by the Electronic Frontier Foundation (EFF), a digital civil liberties advocate. The patent was related to the process used by Instant Live to capture and mix live music concerts and then burn them onto CD so fans can purchase them at the venue immediately following the show.
