Interesting, because I read it in exactly the opposite fashion. The 
actual license doesn't really deal with patents per se, but it does
allow for the use of the materials in preparation of interfacing with
something that uses the specification. This sounds to me like an
explicit statement that the actual product being interfaced to does
not have to be owned by MS.

On the other hand, the promise is a typical non-assert such as the CDDL
uses. In other words, if you use the spec to make a product that
implements it, then MS will not sue you for any patent infringement you
may have done that was necessary to implement it. Sue them for patent
infringement around the same technology and all bets are off.

A couple of points that may be issues. One, that any implementation of
the spec must implement all mandatory pieces of the spec to be covered,
and that the license says "For good and valuable consideration, the
receipt and sufficiency of which are acknowledged", which says that
MS has acknowledged that you have paid in full for the right to access
this material. I am a little unsure that setting the price to zero and
then saying that you have paid in full is exactly kosher. That's why
so many contracts are for one dollar or one penny, to get around this
problem. But then IANAL.
