Microsoft Sues TiVo – The Why of It

“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.

“TiVo is involved in similar disputes with Verizon
Communications Inc., the Dish Network and EchoStar Corp. AT&T
service uses Microsoft technology for video delivery and digital
recording.

“That’s, in my view, Microsoft spin, that it’s doing this to
help out AT&T.”
