According to an article in eWeek, SCO Group has filed a lawsuit in the State Court of Utah against IBM, claiming that IBM worked to "destroy the economic value of Unix" by pushing systems running the Linux operating system and alledgedly sharing AIX (IBMis commercial Unix distribution) source code with Linux developers.
SCO Group, formerly known as Caldera International, purchased rights and ownership of Unix from AT&T in 1995. SCO gained ownership of the Unix name, source code and documentation, development contracts, licenses, and other property related to Unix. All commercial Unix distributors, such as IBM, Silicon Graphics (IRIX), and Sun (Solaris), purchased licenses from AT&T in order to make their own versions of Unix. When SCO purchased Unix from AT&T, they also gained control of these licenses.
SCO is demanding $1 billion in damages from IBM. They are also threatening to pull IBMis Unix license if IBM does not comply within 100 days. From eWeek:
"SCO is in the enviable position of owning the UNIX operating system," said Darl McBride, president and CEO, SCO, in an interview with eWeek Thursday. "It is clear from our stand point that we have an extremely compelling case against IBM. SCO has more than 30,000 contracts with UNIX licensees and upholding these contracts is as important today as the day they were signed."
McBride said the bottom line was that SCO owned the source code to Unix and the right to that operating system. IBM had taken AIX and made it available to the Linux community in an unlawful way.
"IBM has been happily giving part of the AIX code away to the Linux community, but the problem is that they donit own the AIX code," he said. "And so itis a huge problem for us. We have been talking to IBM in this regard since early December and have reached an impasse. This was thus the only way forward for us."
The Unix contracts held by SCO were "extremely powerful and one of the remedies under the contract is that we have the ability to revoke their AIX license," he said. "We have to give them 100 days notice before we do that. If they donit cure the problems we have then we will revoke their license. We sent them a letter today informing them of that, so the 100-day clock has started."
The article goes on to mention that SCO has even hired an expensive legal firm to look for ways to sue Microsoft, Apple, and various distributions of Linux and BSD for infringing on AT&T/SCOis intellectual property.
