Microsoft has sued Kyocera, alleging that the Japanese electronics maker infringed on some Microsoft-owned mobile phone patents.

The suit, filed in U.S. District Court in Seattle, seeks damages and an injunction preventing Kyocera from selling its Android-powered Duraforce, Hydro and Brigadier lines of phones.

Kyocera didn’t immediately respond to an email seeking comment.

The Android mobile operating system was built by Google, but Microsoft contends that it owns the right to some of its underlying technology. The Redmond company in recent years reached agreements with dozens of phone makers to license the Android-related patents.

Microsoft previously sued Motorola in a case similar to the Kyocera suit, and separately filed suit against Samsung arguing that the South Korean phone maker breached their licensing agreement. The Samsung case was settled last month under confidential terms, narrowly avoiding a trial.

“We respect Kyocera but we believe they need to license the patented technology they are using,” David Howard, a Microsoft deputy general counsel, said in a statement. “We’re hopeful this case can be resolved amicably.”
