Just this morning I read a seemingly unrelated article in which the author, a former Motorola Mobility employee, theorized that a little talked-about possibility for Google wanting to buy MMI centers around set-top boxes.
The Google/Motorola Deal is Done. What Now?

According to the article linked above, Motorola moved their "home" division, which includes set-top boxes which Motorola manufacturers, over to Motorola Mobility in an attempt to "sweeten the deal" for Google to buy it. If that assertion is correct then one can conclude that Google is the real entity that just got the ITC to impose a ban on the xBox.
While this may look like another garden-variety patent battle I'll bet it has more to do with the upcoming TV battlefield that, rumor has it, already includes Apple and their yet-to-be-officially-announced AppleTV. The folks at Google appear to be well into their plans to compete with Apple (and Microsoft, which already has a set-top box in xBox).
Silicon Valley is betting huge on TV content streaming and gaming.
