[Posted January 21, 2010 by cook]

Groklaw covers the latest Microsoft patent suit. "Microsoft filed a patent infringement suit against TiVo late yesterday. Microsoft says it's really about defending AT&T, which is one of the companies TiVo has already sued over patents. TIVO says it is too. From the San Jose Business Journal: The action is seen as being related to a lawsuit that Alviso-based TiVo filed against AT&T Inc., claiming the company's U-Verse TV service illegally uses its "time-warping" technology in its digital video recorders."
