Microsoft Gets Back Its FAT Patent In Germany
Dj writes to let us know that Microsoft has regained its FAT patent in Germany. (We discussed it three years ago when the German Federal Patent Tribunal ruled that Microsoft's patent on the FAT file system, with short and long names, was not enforceable.) "The [German] appeal court's decision brings it into line with the US patent office's assessment of the FAT patent. In early 2006, after lengthy deliberations, the latter confirmed the rights to protection conferred by [US] patent number 5,579,517, claiming that the development was new and inventive."
Just too bad that software patents can not be inforced in germany. They only exist for a possible future change of german or european patent law. A change which is currently rather unlikely.
FAT is, indeed, an antique; but it is still pretty much the only FS that is trivial enough to implement in your cheap digital camera or USB MSC MP3 player, or whatever, that is also supported out of the box by MS operating systems.
That is why FAT is still worth something to Microsoft. Even for fairly fiddly embedded systems, there are plenty of free filesystems that are easily good enough. For real computers, FAT would be absurd. If, however, you are making a fiddly embedded system that also has to share a filesystem with a real computer, FAT is basically your choice(or exFAT, which is newer and more evil, and will be patent protected even longer).
Microsoft has absolutely no incentive to support ext2, 3, or 4, or HFS, or any of the others, and NTFS is a bit much for the lighter-weight embedded systems.
FAT is needed because Microsoft has effective control of it's OS platform and any other new filesystem standard is going to create a similar patent and support nightmare.
Microsoft is going to do it's hardest to trap it's users and make everyone else seem like 2nd class (just like Apple does).
A Pirate and a Puritan look the same on a balance sheet.
