The file system that Microsoft Windows and MS-DOS before it has used (if only in part now) for years may well be the subject of coming legal dispute.
[COLOR=#1951B9]"In April, the Public Patent Foundation asked the U.S. Patent and Trademark Office to revoke a patent that covers the FAT (File Allocation Table) file system--the older of two main systems used by Windows to store files."[/COLOR]
Support for FAT and FAT32 has become so common on Linux, Apple Mac, and just about everything else under the sun that its a kind of a standard of sorts in terms of data storage on computer systems. Some people also worry that because the Linux kernel comes with read and write FAT support that its a copyright infringement, after a fashion. However, others feel that its Microsoft who are in the wrong to retain a patent over this file system technology:

"This is the first step toward ending the harm being caused to the public by this patent that should have never been issued."[/COLOR]
