Microsoft's FAT patent upheld
InternetNews | at | by Mike
The United States Patent & Trademark Office completed a reexamination of two Microsoft patents and decided to let them stand.
The patent office ruled that there was no prior art to invalidate Microsoft's '517 and '352 patents, covering aspects of the file allocation table file system, which is used to keep track of the location and sequence of specific files stored on a PC's hard drive, a floppy disk or a Flash memory card.
The Public Patent Foundation, a non-profit that works to improve patent quality and invalidate what it considers bad patents, requested the reexamination in June 2004.
