Aiming to Slim Down Its Patent Risk, RIM Licenses Microsoft’s exFAT File Format
Research In Motion 
has taken a license from Microsoft to the exFAT (Extended File Allocation Table) file format, becoming the latest company to strike a deal for the file storage system technology.
It’s not the first licensing deal between the two companies, as RIM also has a license to use Microsoft’s ActiveSync email protocols.
However, it does mark the latest effort by Microsoft to get rivals to sign a deal for its technology. The company has been going after makers of Android devices in particular, suing Motorola and striking deals with, among others, HTC and Samsung.
