Microsoft On Tuesday, the U.S. Patent and Trademark Office (USPTO) reaffirmed Microsoft's FAT patents (covering the File Allocation Table), but sources close to the Public Patent Foundation indicate that this is not the end of the story of efforts to overthrow these patents. According to sources cited by Linux-Watch.com, the re-issuance of the patent was based on the examiner's having accepted an argument previously advanced by Microsoft, and previously rejected.

>>But there was no prior art<<

There wasn't?

"Microsoft's FAT patent (5,579, 517) is invalid because of three prior art patents, filed by IBM and Xerox in 1988, 1989 and 1990. Microsoft was not granted '517 until 1996."

That would be great if the patent was on FAT, but it is on the system used for storing long file names in vfat.
