In a recent statement, Microsoft has revealed that it has brushed aside a patent settlement offer by Motorola - which has been acquired by Google - in disputes which are threatening to stall the US imports of Android-based devices and Xbox game consoles.

The patent-infringement scuffle between Microsoft and Motorola chiefly pertain to Microsoft's ActiveSync technology, which facilitates the automatic calendar updating process on some Android handsets.

For the use of ActiveSync, Microsoft has been demanding royalties from the manufacturers of all Android-powered devices; and has already worked out licensing deals with most of the leading Android-device makers except Motorola.

According to the proposed settlement-related details shared by Microsoft, Motorola's has come up with the offer of a payment of 33 cents for each Android handset which uses the ActiveSync technology; and has asked for a royalty of 2.25 percent on each Xbox console, as well as 50 cents per copy of Windows for the use of its patents.

About Microsoft rejecting the Motorola patent settlement offer, Microsoft's deputy general counsel Horacio Gutierrez said in a n emailed statement that while Microsoft is open to "any good faith settlement effort," it is difficult for the company to apply that tag to "a demand that Microsoft pay royalties to Google far in excess of market rates, that refuses to license all the Microsoft patents infringed by Motorola, and that is promptly leaked to the press."
