On Tuesday, Microsoft announced a deal with ZTE under which ZTE will license Microsoft’s worldwide patent portfolio for use in cell phones, tablet computers, and other devices running the Android and Chrome operating systems.  Although the terms of the ZTE deal were not released, Microsoft’s agreements with other device manufacturers have required a royalty payment to Microsoft for each Android or Chrome device manufactured.  The announcement follows a similar deal reached last week between Microsoft and Hon Hai (the parent company of Foxconn, which manufactures Android devices for multiple clients), bringing the total the number of device makers who have signed patent deals with Microsoft up to 20.  According to Microsoft, 80% of Android phones sold in the U.S. and the majority of those sold worldwide are now covered by licensing agreements with Microsoft.
