Microsoft filed a patent infringement complaint with the International Trade Commission that claims Belkin is violating its U2 technology patent. According to CRN, Microsoft says that some Belkin products are using the U2 technology without proper licensing.
U2 is a Microsoft technology that allows a peripheral device to automatically detect if it is connected to a PS2 or USB port.
Belkin manufactures mice, trackballs, and other peripherals that attach to computers via USB or the older PS2 ports. The company produces products that are compatible with the Mac and Windows-based PCs.
Microsoft has been trying to for the past two years to get Belkin to enter into licensing negotiations. The company has already signed licensing agreements with other companies, including KYE Systems, Fellowes, Targus, Monterey International, and Behavior Technology Computer.
Microsoft is seeking to block Belkin from importing products that use the U2 technology until a licensing agreement is reached.
