Microsoft has filed suit against Samsung in the US after Samsung failed to make a patent royalty payment last fall. The missed payment came after Microsoft announced that it intended to purchase Nokia's handset business. The suit was filed in a Manhattan federal court.
Microsoft is seeking monetary damages from Samsung, but it is unclear what those damages are. The suit alleges that Samsung refused to make the agreed to payments to Microsoft once the intention of buying Nokia was announced.
Samsung had made payments for an entire fiscal year before the Nokia purchase was announced. Samsung claims that the Nokia purchase violated the licensing agreement in place with Microsoft. Samsung apparently paid the payment late, but has refused to pay interest.
