Microsoft sued Motorola in U.S. District Court in Washington and brought a complaint before the International Trade Commission. Microsoft alleges Motorola infringes on nine Microsoft patents related to key smartphone experiences such as syncing e-mail, calendar, and contacts, and notifying apps about changes in signal strength and battery power, Microsoft said. The complaint cites Motorola’s Droid 2 phone as an example.
“We ve a responsibility to our customers, partners, and shareholders to safeguard billions of dollars we invest each year in bringing innovative software products and services to market,” Microsoft’s Horacio Gutierrez said. “Motorola needs to stop its infringement of our patented inventions in its Android smartphones.”
The suit comes as Microsoft is trying to line up phone makers to use its Windows Phone 7 operating system. Although Google-developed Android can be used free of charge.
