Microsoft FAT patents upheld

A set of long-disputed patents that Microsoft has on several variations of the FAT file system have been upheld, allowing Microsoft to either stay their current course or, as they claim they will, license the technology on a larger scale. Though FAT has been superseded by NTFS in modern Windows systems, FAT is used in a very large number of devices still, especially on devices using flash memory such as cameras, thumb drives, compact flash cards and more. A year ago, the Public Patent Foundation requested that the patents Microsoft owns be re-examined, because they felt that others had developed the file system earlier. While partially true, the patent office found that the differences were enough to make Microsoft's version “Novel”, allowing them to keep the patent.

”All along, Microsoft voiced confidence that the patents would be upheld. David Kaefer, the company's director of business development, said Tuesday that the company was "very pleased" with the office's final decision. "This result underscores the validity of these patents but also the importance of allowing third parties to request re-examinations," he said in a statement.
So far, the waters are still and few bad tidings have come because of this, but Microsoft still has the right to at one point start collecting. It's likely that we'll see more examination of the technology over time.

  1. well, personally i preffer the NTFS format.
  2. What surprises me most about this is the fact FAT is still used. I didnt know so many devices still used the file structure. I thought we were done with FAT with 98.
  3. Most flash or compact storage drives still use FAT 32 rather than NTFS. Some newer flash drives default the format to NTFS, while most still tops out at FAT 32. For an item like flash drives, it hasn't made much, if any, difference storage-wise. But with the advent of NTFS, I really don't see why companies/foundations are fighting over an outdated file system. It seems like flash drives are moving towards the NTFS file system, and with technology progressing forward, it wouldn't be unreasonable to think other digital devices - flash cards and the likes - to follow suit.
  4. Memory sticks use FAT16/32 probably because they can be read and written in virtually any operating system.I wouldn't have fun with NTFS USB stick switching between Windows, Linux and OSX.
  5. It's always great to hear about people challenging Microsoft.
  6. "A set of long-disputed patents"Lol, you might as well just have said "A set of disputed patents", whenever theres a patent dispute it is, by its very nature, long.That said, any company that uses FAT has a very large interest in freeing up its patent obligations to MS. For now, if MS decided to, it could attempt to impose retroactive licensing fees for its patents, and charge companies for the years they have been using the FAT system whilest 'infringing' on MS's patent rights. Failing that, they could file for injunction which would require that production for all devices that use the FAT system be halted immediately and permanently, or until a settlement is reached between MS and the 'infringer'.Even though the technology is outdated, there is still a lot at stake for everyone involved.

  8. I thought we were done with the Fat file also, but if NTFS is better, then I see no reason to use it, if its at all possible to do so.
  9. MonkeyMan, look above at what Mictlantecuhtli said. NTFS isn't going to allow me to take my files from a windows machine to a linux machine to a mac machine.That is why FAT is still in use.
  10. Okay, I'll concur; never thought about transferring files between the different operating systems. And I guess that makes sense why most flash drives are still utilizing FAT file system over NTFS. Always nice to learn something!
  11. Well, Linux and OSX can read NTFS. Linux can also [url=http://sourceforge.net/projects/linux-hfsplus]read and write HFS+[/url] (OSX's filesystem), Windows won't understand that. OSX can [url=http://sourceforge.net/projects/ext2fsx/]read and write ext2[/url] (a filesystem in Linux), Windows has a [url=http://ext2fsd.sourceforge.net/]driver for ext2[/url].I don't know how UDF would work, but that could be a possibility as well (DVD-RAM and some "drag'n'drop CD" systems use it).
  12. My HD uses FAT32 and the floppies normally use FAT. In any case, it hasn't become obsolute yet, so therefore shouldn't be ignored.
