Cisco is suing TiVo over DVR patents TiVo claims Cisco is infringing on.
According to Reuters, Cisco has filed a lawsuit to void four TiVo DVR patents that Cisco says TiVo is wrongfully alleging infringement of. Cisco says TiVo has resisted granting a broad license to its technology because it would rather gain revenue from settling infringement lawsuits, according to the Reuters story.
"Absent a declaration of invalidity and/or non-infringement, TiVo will continue to wrongfully allege that Cisco DVRs and Cisco's customers infringe the TiVo patents, and thereby cause Cisco irreparable injury and damage," Cisco said in a statement to Reuters.

Cisco sells DVRs through its Scientific Atlanta cable set-top box business. TiVo sells its own set-top boxes and licenses technology to cable TV operators.
Cisco sued in the federal court in San Jose. It seeks a court order that voids the TiVo patents or declares that Cisco and its DVRs are not infringing them, according to Reuters.
A TiVo spokesperson said the company could not comment on the Cisco suit.
In addition to acquiring Scientific Atlanta and its intellectual property in 2005 for $7 billion, Cisco is acquiring NDS for $5 billion. NDS is a maker of software designed to create pay TV video offerings that enable subscribers to view, search and navigate digital content on any device.
NDS products include set-top/DVR, program guide and digital-content software, and video headend systems. Customers include cable and satellite TV providers.
