    Default Samsung Properly Open-Sources exFAT File-System

    Phoronix: Samsung Properly Open-Sources exFAT File-System

    Back in June, Phoronix was the first to report of a native exFAT file-system implementation for Linux that appeared on GitHub. It later turned out that Samsung accidentally leaked their exFAT source code. The solution has now been corrected with Samsung formally open-sourcing their exFAT source code...

    I presume this only resolves the code license issue - that patent license issues still remain, and that Samsung has licensed the patents - for their own use.

    In a very quick comparison of their 1.2.4 source to the leaked one, it seems they removed all comments in the process...

    This is to show their support to open source folks, I guess.

    Does this mean whoever uses this won't have to pay Microsoft for their own FAT patents anymore?

    Dream on.

    Microsoft still holds the exFAT patents. Samsung licensed them for their own use only. Im not surprised if Microsoft revokes Samsung's patent license for the exFAT driver, thus making it illegal for anybody to download and use Samsung's driver source code, since Samsung clearly did not get Microsoft's approval to open their driver.

    plus im damn sure that whatever the licensing terms for the exFat patents are, royalty-free dissemination is definitely not one of them.

    Only if it were released under GPLv3. In that case Samsung would have to pay Microsoft for everybody

    I'm no lawyer so I can't be too sure, but I think the answer here is No. I think Microsoft exFAT's patents still apply even if there's an open source implementation of them in circulation. That's to say, if you use it, you're the one who is going to get sued by Microsoft, not Samsung.
    But then again, it's probably dependent on where you are in the world and how much of a legal team you can afford.

    not everyone is american
    it's still legal to use a US software patent in the majority of countries without paying a penny to M$
    and for US citizens , the law does not sue particulars for private non-commercial use of patented technologies

    Nope.
    Code license is about the code. Patent license is about what the code do.
    The two are completely separate.
