Microsoft backs AT&T, sues TiVo over TV technology
PHILADELPHIA — Microsoft is backing AT&T in a patent lawsuit that TiVo has filed against the phone company. Microsoft’s tactic: Filing a lawsuit of its own against TiVo.
Microsoft is suing TiVo for allegedly infringing on patents that cover an on-screen TV guide and a technology for letting viewers order and view shows. This comes in response to TiVo’s lawsuit against AT&T last year for allegedly infringing on a technology that lets viewers pause and rewind live TV.
Microsoft’s Mediaroom software is used in AT&T’s set-top boxes and the company could be held financially liable if TiVo prevails.
TiVo has also sued Verizon over the same patents and won a string of court victories against Dish Network. That case is being appealed.
