Alviso, Calif. -- Following a $105 million victory in a still ongoing patent infringement dispute with DISH Network owner EchoStar, Alviso-based TiVo on Wednesday filed additional claims against AT&T and Verizon, alleging the companies are violating its digital video recorder patents. Filed in federal court in the Easter District of Texas, the complaints seek injunctions that would prevent AT&T and Verizon from distributing set-top boxes with the allegedly infringing technology, in addition to unspecified damages. AT&T offers a digital TV service called Uverse, while Verizon operates one called FiOS TV. Both offer their subscribers set-tops with digital video recorders.
