Microsoft says Motorola is violating the software maker's technology patent by using Google's Android software in Moto phones. The Android software includes an operating system and key applications for mobile devices. The functions in question include synchronizing e-mail, calendars and contacts.
Microsoft filed its lawsuit today in the U.S. District Court for the Western District of Washington. It's also filed a claim with the International Trade Commission.
In a statement, Horacio Gutierrez of Microsoft said, "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."
Motorola wouldn't immediately comment on the lawsuit. But a statement released by the company says it has one of the strongest intellectual property portfolios in the industry and that Motorola will "vigorously defend itself in this matter."
