Microsoft announced on Monday a patent licensing agreement with Motorola Solutions, Inc., a provider of communication solutions and services for enterprise and governments. The license provides worldwide coverage under Microsoft's patent portfolio for Motorola Solutions' devices running the Android platform and Chrome OS operating system.

Microsoft has also signed Android and/or Chrome OS patent-licensing deals with more than 20 companies, including Dell, Samsung, LG, HTC, Acer, Barnes & Noble and Amazon.

Note that today's deal has nothing to do with Motorola Mobility. Motorola Solutions is the communications-services part of Motorola that sells embedded devices. Google sold Motorola Mobility to Lenovo in late January 2014.
