TiVo Sues Verizon, AT&T For Infringement of Patents

  • Bloomberg, Wednesday, August 26, 2009 10:14 PM

TiVo is suing Verizon and AT&T claiming infringement of patents used in their DVR systems. TiVo claims infringement of its so-called "time warp" patent and two others.

The time warp patent was at the center of another dispute with Dish Network and EchoStar. They were ordered in June to pay $192.7 million to TiVo and to stop providing the Dish DVR service. That ruling, by a federal judge in the same jurisdiction as this new suit, is under appeal. The fight with Dish has been going on since 2004.

TiVo claims AT&T and Verizon also infringe on a patent that covers the real time capture, storage and display of television broadcast signals. The Verizon complaint targets the FiOS television and Web service offered through the company's Wireline unit. Verizon had 2.5 million FiOS TV customers and 3.1 million FiOS Web customers as of June 30.
