If you don't trust the OSP (Open Specification Promise), ask for a patent license at Microsoft, this is for the "Word Binary File Format (.doc) Structure Specification":

Patents. Microsoft has patents that may cover your implementations of the formats. Neither this notice nor Microsoft's delivery of the documentation grants any licenses under those or any other Microsoft patents. However, the formats may be covered by Microsoft's Open Specification Promise (available here: http://www.microsoft.com/interop/osp). If you would prefer a written license, or if the formats are not covered by the OSP, patent licenses are available by contacting moc.tfosorcim|glpi#moc.tfosorcim|glpi.

Let's try to see if requesting a RAND patent license at this email address works. The first one who manages to obtain a copy will receive a present from us.

I have sent a request to see the terms of the RAND license, let's see how long it takes to have a copy:

subject Request for a written license for ECMA 376 implementation

Dear Microsoft Licensing,

I would be interested to receive a copy of the terms of the proposed
written patent license that you propose for the standard ECMA 376, as
mentioned by one Microsoft employee on the following page:

http://doyoulovems.com/archives/64#comment-58

"Microsoft has chosen to provide implementers with three different
options from which they can choose. Some companies prefer to rely on a
CNS or patent pledge. Some companies (sometimes that have a large
commercial operation) prefer to enter into a bi-lateral license
agreement as opposed to relying on a CNS or OSP-like promise. By
offering all three choices, Microsoft has tried to accommodate the
different preferences of different implementers that may be based in
part on differing business models."

According to several legal analyses, the OSP is not trustable and I
would prefer to see if the proposed written patent license offers
better guarantees for redistribution of implementations of the
standard.

Best regards,
