Microsoft today sued Motorola for allegedly violating patents with its Android-based phones. The complaints with both the International Trade Commission and in a Western District of Washington court claim that the devices copy technology "essential" to the smartphone experience, such as calendars and contacts, e-mail sync and notifications for apps of battery and connection levels. The accusations didn't initially include any damage values, but an ITC investigation would lead to a ban on Motorola phones in the US if successful.
