That document seems to protect authors of open-source code, but not corporate users of said
code, unless I read it incorrectly.
That was the specific concern that was raised by the HttpClient team.  However, the good news
is that it appears there is no 
patent around NTLM, which is the protocol in question.  It's explicitly mentioned in this
document, page 9, item 14:

What do you think?
Thanks,
Karl
