Microsoft and LG Electronics have signed a patent agreement that provides broad coverage under Microsoft's patent portfolio for LG's tablets, mobile phones and other consumer devices running the Android or Chrome OS Platform.

Microsoft said that the contents of the agreement will not be disclosed.

"We are pleased to have built upon our longstanding relationship with LG to reach a mutually beneficial agreement. Together with our ten previous agreements with Android and Chrome OS device manufacturers, including HTC, Samsung and Acer, this agreement with LG means that more than seventy percent of all Android smartphones sold in the U.S. are now receiving coverage under Microsoft's patent portfolio," said Horacio Gutierrez, corporate vice president and deputy general counsel, Intellectual Property Group at Microsoft.

Since Microsoft launched its IP licensing program in December 2003, the company has entered into more than 1,100 licensing agreements.
