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.
