PUBPAT Challenges Microsoft's FAT Patent
An anonymous reader writes "The Public Patent Foundation filed a formal request with the United States Patent and Trademark Office today to revoke Microsoft Corporation's patent on the FAT File System, touted by Microsoft as being 'the ubiquitous format used for interchange of media between computers, and, since the advent of inexpensive, removable flash memory, also between digital devices.' In its filing, PUBPAT submitted previously unseen prior art showing the patent, which issued in November 1996 and is not otherwise due to expire until 2013, was obvious and, as such, should have never been granted."
Scary: That's patent worthy.
Scarier: There were three prior patents covering the technique...
Microsoft's 'FAT' patents do not patent FAT... specifically, they patent the VFAT extensions to FAT. And, as was previously mentioned on slashdot, there's much prior art to using long file names on FAT as well.
So don't call them 'FAT' patents, because they aren't. Call them VFAT patents. Or call them by their names, which also makes it obvious.
pb Reply or e-mail; don't vaguely moderate.
The microsoft patents aren't about all of the FAT file system. Rather the method of storing short and long file names in the FAT file system.
Interestingly, the request for reexamination is based partly on what Microsoft might do, and has made no attempt to do. Their assertions are that in light of other patents the specific combination of techniques would have been obvious. This strikes me as less than genuine because of how patents are done, particularly in this day in age. If the combination of ideas was so obvious, why didn't the last of the submitted prior art patent it, since they're so skilled they can claim worthy patents when there is significant pressure to claim everything thing concievable at the time of the filing?
But more importantly; in the case of the invention of polyamides, with their logic the claimed invention of one precludes others from claiming the invention of others of similar structure. In light of Nylon, Kevlar is obvious.
This of course is not what happened.
I'm not saying that shouldn't have happened. It's an interesting demand to make of would be inventors, and certainly a considerable demand to make of the patent office. (I guess we know that when they play Stars! 2 they always click the bleeding edge technology box.) But the fact that their line of reasoning isn't followed, really at all, and has many billions, possibly trillions, of dollars in property bet against it doesn't bode well I would think.
Didn't 4DOS support long filenames on top of FAT long before VFAT (Windows 95) did?
I'm pretty sure I remember using 4DOS around the DOS 3.3 to DOS 5.0 days.
My other first post is car post.
