Microsoft Sues TiVo Over Patents

Six months after TiVo sued AT&T (NYSE: T) for patent infringement, Microsoft (NSDQ: MSFT) has entered the legal fray. In a filing, Microsoft asks to be a party in the suit because it says the case puts into question its Mediaroom software, which runs on set-top boxes that use AT&T’s U-verse subscription service (TiVo (NSDQ: TIVO) alleges that U-verse is infringing on three of its patents).

Microsoft is also suing TiVo for infringing on two of its own patents, including one for a “system for displaying programming information” and another related to the “secure purchase and delivery of video content programs,” according to another filing. A Microsoft spokesman tells Bloomberg that the company is “open to resolving this situation through an intellectual-property licensing agreement, and we have initiated discussions to engage TiVo in negotiations.”

TiVo, unsurprisingly, does not think Microsoft should be suing it for patent infringement—or should be involving itself in the AT&T litigation. Here’s the company’s full statement: “Microsoft’s recent legal actions, including its decision to seek to intervene on behalf of its customer, AT&T, and its recent complaint against TiVo in U.S. District Court, Northern District of California do not bear on whether the AT&T products and services that are the subject of TiVo’s complaint infringe the patents asserted by TiVo. Rather these actions are part of a legal strategy to defend AT&T. We remain confident in our position that AT&T will be found to infringe on the TiVo patents asserted.”
