PVR specialist TiVo, via its Rovi owner, has hit cable giant Comcast with another patent misuse legal action and alleging that Comcast is infringing six of its technology patents.
Specifically, TiVo/Rovi is arguing in a Los Angeles federal court that Comcast’s X1 video recording hardware and software infringed six TiVo/Rovi patents.
The alleged misuse covers various DVR functions, including technology that allows users to easily restart programmes and methods for displaying real-time data such as sports scores within interactive programme guides. Additionally, the writ says that Comcast is using TiVo/Rovi’s multi-room functionality.
Comcast and TiVo had entered into a licensing agreement for the use of TiVo technology but that agreement expired in 2016. Comcast, in essence, is arguing that it has since developed its own technological solutions that do not infringe TiVo patents.
“Rovi has in recent years deployed its increasingly obsolete patent portfolio in an unsuccessful litigation campaign seeking to charge Comcast and our customers for technology that Rovi did not invent,” a Comcast official said in a statement. “Rovi launched this campaign in April 2016 by asserting infringement of 15 patents – 14 of which have been held to be invalid and/or not infringed by Comcast, or have been withdrawn by Rovi. While we haven’t had an opportunity to review Rovi’s latest complaint, we will continue to defend ourselves against allegations we determine to be meritless.”
