ALVISO, Calif. (
has taken aim at phone giants
with a patent infringement lawsuit.
The TV recording specialty shop filed complaints in the U.S. District Court in the Eastern District of Texas saying AT&T and Verizon violated its DVR patents and is seeking damages and a permanent injunction.
AT&T and Verizon have been expanding a TV service as part of a triple play service bundle, which has been chipping away at subscriber numbers at
Time Warner Cable
The move is similar to the ongoing lawsuit in the same court against
over the DVR recording technology used by
EchoStar has lost and appealed several decisions in the TiVo case. In June, the court awarded TiVo $103 million. Last year, EchoStar made a $105 million payment to TiVo.
