TiVo Relaunching As a Patent Troll?

An anonymous reader writes "TiVo's quarterly call was a bit more dramatic than usual. While they continue to lose customers and innovate 'at a very unhurried pace,' TiVo seeks a repeat DISH Network performance in going after AT&T (T) and Verizon (VZ) for infringement. Basically, TiVo's current business model appears to be ad sales and patent trolling."
