You'll remember (maybe) that TiVo and AT&T have been having something of a fight (http://www.engadget.com/2009/08/26/tivo-projects-larger-than-expected-losses-still-taking-the-pate/) over a few different patents primarily related to time shifting. Now Microsoft is suing TiVo, saying that it has stepped on two patents used in AT&T's U-Verse (http://www.engadget.com/tag/u-verse)), which you'll recall relies on Microsoft's Mediaroom (http://www.engadget.com/tag/mediaroom). Want to hear some of the legal verbage in question? "A system that displays programmable information and a secure method for buying and delivering video programs." It's vague and all-encompassing, and that's just how we like our patent kerfuffles.Microsoft has AT&T's back, sues TiVo for patent infringement (http://www.engadget.com/2010/01/20/microsoft-has-atandts-back-sues-tivo-for-patent-infringement/) originally appeared on Engadget (http://www.engadget.com) on Wed, 20 Jan 2010 08:19:00 EST.
