Alviso, Calif. - Following a $105 million victory in a still ongoing patent infringement dispute with DISH Network owner EchoStar (NASD: SATS), TiVo (NASD: TIVO) on Wednesday filed additional claims against AT&T (NYSE: T) and Verizon (NYSE: VZ), 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 for past infringements.

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.
