Sender-ID uses SPF syntax, Microsoft claims to have patents pending on
Sender-ID and PRA, therefore it is not impossible that microsoft is

Yes, that doesn't follow. The IPR specifically states that it only
covers what is in the core and pra drafts. It does not cover anything
in the protocol draft, which is where the syntax of the records and the
interpretation of that syntax are defined. If Microsoft was going to
claim any IP rights over that they would have had to file an IPR for
the protocol draft as well. They did not.
