“The SCO Group (SCO) delivered final written notice yesterday to
Sequent Computer Systems for termination of its UNIX System V
software contract. Sequent is now owned by IBM. The Sequent (IBM)
contract was terminated for improper transfer of Sequent’s UNIX
source code and development methods into Linux. As a result, IBM no
longer has the right to use or license the Sequent UNIX product
known as ‘Dynix/ptx.’ Customers may not acquire a license in
Dynix/ptx from today’s date forward.“SCO’s System V UNIX contract allowed Sequent to prepare
derivative works and modifications of System V software ‘provided
the resulting materials were treated as part of the Original
[System V] Software.’ Restrictions on use of the Original System V
Software include the requirement of confidentiality, a prohibition
against transfer of ownership, and a restriction against use for
the benefit of third parties. Sequent-IBM has nevertheless
contributed approximately 148 files of direct Sequent UNIX code to
the Linux 2.4 and 2.5 kernels, containing 168,276 lines of
code…”
