Apparently (or as expected), Microsoft owns the patent to such widely-used and totally common phone features and technologies, which include "synchronizing email, calendars and contacts, scheduling meetings, and notifying applications of changes in signal strength and battery power."
Microsoft quoted Android OS' patent infringement of these nine technologies in an ITC case that the company filed against Motorola yesterday. Android is the operating system of some hit Moto handsets like Motorola Droid aka Milestone, BackFlip and Droid 2.
It's interesting to see how this case will pan out. Will the two companies fight it out until the end or will they immediately agree on a cross-licensing agreement? We'll all have to stay tuned for updates.
In the meantime, kindly read Microsoft's brief press release on the case --
