TiVo is involved in another big fight over DVR patents.

Cisco Systems has filed a lawsuit against the DVR pioneer that seeks to invalidate four of TiVo's patents and is asking for a declaratory judgment that its products are not infringing.

The plaintiff says in a lawsuit filed in California federal court that it is facing a threat from TiVo, which has resisted giving a license to reserve the possibility of a lawsuit. Cisco is a provider of DVRs to AT&T, Time Warner Cable and Verizon Communications, among others.

"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," the Cisco lawsuit argues.

TiVo declined a request for comment.

The company has previously been involved in litigation with Microsoft, AT&T, Motorolla, Verizon and Dish. The lawsuits have yielded some big-dollar settlements including $500 million from Dish last month and $215 million from AT&T earlier in the year. The company's dispute with Microsoft also was recently resolved.
