BetaNews | Two Microsoft FAT Patents Rejected

BetaNews | Two Microsoft FAT Patents Rejected: "The U.S. Patent and Trademark Office rejected Microsoft's patent application for its File Allocation Table (FAT) file system technology on Tuesday, however the Redmond company has put on a brave face and told BetaNews that it expects to ultimately be victorious.
In June of last year, the USPTO agreed to review the patent after questions arose surrounding its validity. A group known as the Public Patent Foundation disputed Microsoft's claims to FAT in April 2004, saying it had become ubiquitous as a format and found in many devices."
