In case it was lost in the informative explanations of others, here's the
short version:

* UNIX is a trademark of the Open Group.  Unix is not.

* The UNIX source code's copyright is held by . . . damn.  It keeps
  changing.  I remember that it was once owned by Novell, but I think
  they might have sold it after the whole SCO fiasco.

FreeBSD uses BSD Unix source, not SysV Unix source, both of which are
descended from original AT&T UNIX source -- but the BSD Unix source is
distributed under the BSD License, while the SysV Unix source copyright
is tightly controlled under proprietary terms.

For any of the above to be called UNIX, it must meet the Open Group's
certification standards and (more importantly) have some certification
fee paid, as I understand it.
