The U.S. Patent and Trademark Office has rejected two key Microsoft patent applications relating to its File Allocation Table file system. But Microsoft officials still hold out hope that the company ultimately will succeed in the quest to patent FAT.
In June 2004 the USPTO (U.S. Patent and Trademark Office) said it would re-examine the patent Microsoft Corp. holds on FAT, a format used for the interchange of media between computers and digital devices.
