Reuters:
Microsoft Corp has brushed off an offer by Motorola, the phone maker bought by Google Inc, to settle patent disputes with Motorola that are threatening to halt imports of Android devices and Xbox game consoles into the United States.

The patents at issue relate to Microsoft technology called ActiveSync, which updates calendars automatically on some Android phones. Microsoft is demanding royalties from all companies using Google's Android system in their devices, and has settled with most major manufacturers except Motorola.
