Cisco Systems Inc. filed suit against TiVo Inc. on Wednesday, asking that four DVR patents be declared invalid, Reuters reported Friday.
The suit, filed in San Jose, Calif., claims that TiVo has refused to license its patents in order to continue suing companies. If the patents can't be invalidated, Cisco at least wants a court decision that its DVRs don't infringe on them.
Why this matters
Cisco apparently wants to stop TiVo's run of lawsuits before getting sued itself. This would save Cisco some legal costs, but it would also take potential hassle away from some Cisco customers, the operators that have been among TiVo's targets.
TiVo has settled with AT&T Inc. and the tandem of Dish Network Corp. and EchoStar Corp. LLC, and it's reached a stalemate with Microsoft Corp.. It's still in litigation against Motorola Mobility, now owned by Google, and Verizon Communications Inc..
