LINUX&UNIX - SCO vs.IBM Complaint
Unix was invented more than 30 years ago by AT&T's Unix Systems Laboratories. In many ways Linux works similarly to Unix, making it relatively easy to translate Unix software to Linux.
AT&T sold the Unix intellectual property to Novell Networks, which in turn sold it to the Santa Cruz Operation. Caldera International, a seller of Linux, then acquired from SCO the Unix rights and two SCO products, OpenServer and UnixWare. Then last year, Caldera changed its name to SCO Group to reflect the fact that most of its revenue came from its SCO business and not from the Linux products.
But SCO has recently alleged that parts of the Unix source code have been copied into Linux, and it is seeking fees from Linux users. In March, SCO sued IBM for $1 billion, alleging that Big Blue had used SCO's Unix code in Linux. IBM, along with Hewlett-Packard, has been a major backer of Linux. Last week, SCO escalated the battle by sending letters to about 1,500 large corporations warning them that their use of Linux could infringe on SCO's intellectual property.
