Licensing notes:

• Linux was inspired by MINIX and Unix, but Linux and GNU code was written from scratch.
• BSD was originally based on code copyrighted by AT&T, but over the period 1989–1994, was rewritten to purge all AT&T code.
• The Single UNIX Specification controls access to the Unix trademark, owned by The Open Group.
• Novell purchased the Unix copyright from AT&T, which it still owns as of August 2010 (see SCO v. Novell).
• The Santa Cruz Operation purchased the right to develop and sublicense SCO OpenServer and UnixWare from Novell, which it sold to what is now (2010) the SCO Group (see SCO v. Novell).
• IBM AIX is a licensed Unix derivative, as is HP-UX
