Microsoft has filed suit against Motorola today in both the International Trade Commission and U.S. District Court for the Western District of Washington. Microsoft is claiming that Motorola has infringed on nine of Microsoft's patents in their Android smartphones.

The patents in question relate to the synchronization of email, calendars and contacts, scheduling of meetings, and notifying applications of changes in signal strength and battery power.

In a brief press release Horacio Gutierrez, Microsoft's Corporate VP and Deputy General Counsel stated,"We have a responsibility to our customers, partners, and shareholders to safeguard the billions of dollars we invest each year in bringing innovative software products and services to market. Motorola needs to stop its infringement of our patented inventions in its Android smartphones."

If successful, Motorola could be on the hook for damages and have their Android smartphones banned in the U.S. No response from Motorola on the claims and if you want to sift through the 243 page Federal Court filing, you can find it here.
