80% of MS Server Protocols Are Unpatented

Posted by timothy on from the minefield-aerobics dept.

    I agree, it does seem like they're trying to imply that there's only a 1 out of 5 chance that anything related to the Samba technical detail licensing is patented.

    Here is a relevant link:

    http://samba.org/samba/PFIF/ - The Samba licensing announcement.

    The announcement has a lot of ambiguities (and IANAL), but it appears hey agreed that:

    1) Samba Team members would receive access to protocol documentation. This information would only be available to Samba Team members, and available only under NDA
    2) Access to information would not restrict CODE that could be produced using this information
    3) It does not provide any patent coverage.
    4) However, Microsoft would provide a list of patents covering the protocols used by Samba, and keep the list updated. This provides Samba folks a way to understand exactly what methods to avoid - which infringe patents.
    5) Microsoft agreed that any patents not detailed in this list and found to be infringed cannot be "asserted" by Microsoft.

    Presumably, there are items that MS will provide for #4, so there are patents that relate to Samba.
