German Court Invalidates Microsoft FAT Patent

walterbyrd sends this news from Techworld: "A Microsoft storage patent that was used to get a sales ban on products from Google-owned Motorola Mobility in Germany has been invalidated by the German Federal Patent Court. Microsoft's FAT (File Allocation Table) patent, which concerns a 'common name space for long and short filenames' was invalidated on Thursday, a spokeswoman for the Federal Patent Court said in an email Friday. She could not give the exact reasons for the court's decision before the written judicial decision is released, which will take a few weeks."

      scratch that, VFAT was introduced with NT3.5 (September 21, 1994), so the patent was probably filed for in anticipation of the NT3.5 release.

      from the same wikipedia article: http://en.wikipedia.org/wiki/File_Allocation_Table

      OS/2 added long filename support to FAT using extended attributes (EA) before the introduction of VFAT; thus, VFAT long filenames are invisible to OS/2, and EA long filenames are invisible to Windows, therefore experienced users of both operating systems would have to manually rename the files.

      First thing - a card mounted via UMS (USB Mass Storage) to a PC isn't available to Android OS.

      Well, they would just have to design it differently. I don't see a principal reason why it should not be possible for the card to be available to both at the same time.
      Also, who says that the card must be directly available to the PC via UMS while inserted in the phone?

      Think of all apps (and their data) installed on the card and how would they behave if the card suddenly becomes invisible to Android...

      Simple solution (if for some reason not removing the underlying problem, see above): Suspend the apps before unmounting the card, and unsuspend them after the card gets available again.

      Second thing - security issues. FAT filesystem on most SD card - no file ownership.

      Sure. Because it is impossible to keep your SD card physically secure. Hint: Unless you're encrypting your files, file system level security is moot as soon as the attacker has access to the physical medium. And if you're encrypting the files, file ownership is moot, too: It's the key which controls who can read it.

      One of the core Android principles is that you never need a file manager. With a memory card mounted a user can start to wonder where data (photo, music, file) ends up.

      Yes, that is what I am trying to say.

      In terms of actual EU courts, we have the EU General Court, but that only has competence to hear cases against the EU itself. For example, if the European Patent Office refuses to grant your patent application, you can go there to appeal your decision, or if the EU competition authority thinks you are behaving in an anti-competitive manner, you will face trial in that court.

      Most other cases involving EU law are heard in national courts, with the European Court of Justice as the final court of appeal. Generally speaking, judgements in national courts are binding only in that country, but persuasive elsewhere in the EU. ECJ judgements are binding in the whole of the EU. The exception is cases involving copyrights, patents, trademarks and registered designs (known as design patents in the US). For those cases, the national court sits as an EU court, and judgements are binding throughout the EU. Another exception is the EU small claims procedure, where consumers can take cases against suppliers in other EU countries in their local court, and the local court will work the the court local to the supplier to sort out the dispute. Small claims cases are not legally binding, but can be appealed to the European Court of Justice, who's judgements are legally binding.

    One of the important requirements for a patentable invention is that it must be "useful".

    This patent originally covered a way to provide compatibility between short and long file names. But nobody has used short file names in decades.

    So now, the "feature" continues to be necessary only so that FAT can provide compatibility with itself. That's like begging the question. The feature no longer has any intrinsic usefulness, and in fact just serves to make the file system format more convoluted and less efficient.

    The patent system ought to be changed so that any patent should be revoked once it is no longer useful for its intended purpose. This particular patent has recently been "useful" solely as a way to give Microsoft leverage in the media device market. The covered feature provides zero benefit to end users.

      Sorry, but you describe a useful function. Whether it's relevant any more or not is neither here nor there. If I invent a way to make a clockwork mechanism work more efficiently, that's still an invention, still patentable. And, as Trevor Bayliss shows, still something that should be protected by patents even if it's "old hat".

      The real crux of the matter is whether FAT is "obvious to one skilled in the art" which is a much, much, much more relevant and important test of patentability. Fact is, it pretty much is. If you're a filesystem designer and you're handed FAT and told to make it store long file names, FAT LFN's are pretty much one of a million ways to do them - and not even a particularly effective or perfect one.

      Lacking such "inventiveness", and being just something that anyone with half a brain could come up with, AND being in a jurisdiction where software patents shouldn't be allowed by the EU courts anyway, that's what means it should be invalidated. By the same token, BTW, Trevor Bayliss would also fail. What he did wasn't invention, just quite a smart combination of two existing technologies. But at least it was a physical invention and not a way to get Linux-based vendors (e.g. TomTom) to pay Microsoft money for Windows-only inventions.
