The article raises, but does not answer, the question in the title given here on HN. The article does provide a useful precis of the the history and implications of Novell's purchase by Attachmate, and it provides the simple answer "no", in that the Unix copyrights are not now the legal possession of Microsoft. Microsoft has acquired patents in the deal, but there is no clarity on what that means for Unix, nor is it clear what use Attachmate will make of the copyrights it now owns (aside from continuing operation of the Novell business for the immediate future).
