The company, which is pursuing a $1 billion lawsuit against IBM for allegedly improperly including SCO's Unix intellectual property in Linux, announced Monday that it has suspended all future sales of Linux "until the attendant risks with Linux are better understood and properly resolved."
The company said it issued the warning based on its findings of illegal inclusions of SCO Unix intellectual property in Linux.
SCO has raised the hackles of members of the Linux community for its stance, and has sought to link a recent denial of service (DoS) attack against its network with members of the Linux community "who are hostile toward SCO for asserting its legal rights," in the words of company spokesman Blake Stowell.
SCO's lawsuit against IBM came two months after it unveiled SCOsource, a new branch of the company focused on licensing its intellectual property, specifically the Unix System V libraries for Linux.
"SCOsource is just one small part of what SCO is doing," Sontag said at the beginning of May. "The majority of the company is working on next generation versions of the UNIX operating system and on Linux products."
SCO sued IBM for allegedly misusing trade secrets after IBM walked away from a joint project with SCO which sought to create an Intel Itanium version of SCO's UnixWare. IBM scrapped the effort, dubbed Project Monterey, when it decided to focus its attention on Linux rather than Unix. But SCO maintained that IBM's rapid strides with Linux were built on trade secrets it garnered from Project Monterey -- especially the integration of UNIX System V libraries with Linux, which allows the Linux platform to run many Unix applications.
"Things came to a head at LinuxWorld, and we decided our only choice was to file a suit," Sontag said.
"Our full intent is to see this through all the way," Sontag said. "We're well resourced to be able to do that."
