Wednesday sued AT&T (NYSE: T) and Verizon Communications for infringing its patents, including one covering the ability to pause and rewind live TV.
"There are multichannel operators who compete with us through the unauthorized use of our intellectual property," said TiVo CEO Tom Rogers, in a conference call with analysts.
He added that while there were talks, "business agreements have not been reached."
AT&T declined to comment.
Verizon said it hasn't seen the lawsuit yet and can't comment.
Setback in Dish Case
Separately, TiVo received a setback Wednesday in a similar patent lawsuit against Dish Network and sister firm EchoStar (Nasdaq: SATS) .
The U.S. Patent and Trademark Office ruled that the re-examination of TiVo's patent that's the subject of litigation may continue.
TiVo had asked the agency to vacate Dish's request to look anew at the patents.
Wrangling Over Workaround
TiVo sued Dish in 2004, alleging that Dish infringed on its DVR technology. Dish lost.
While the case was on appeal, Dish designed a modified software that it downloaded to customers' DVRs.
However, TiVo said the workaround software still infringed on its patent and asked the district court for a permanent injunction.
