Last week SCO alleged that IBM tried to destroy the economic value of Unix, particularly Unix on Intel-based servers, to benefit its Linux services business, alleging misuse of Unix code.
Sun has responded by insisting that it has licensing rights to Unix code, on which the Solaris operating system is based for both SPARC and recently available Intel-based x86 systems.
Sun said it had "absolutely no licensing issues with SCO today", and that its previous licensing agreements gave the company complete rights to use Unix in its operating systems.
It insisted that it had "a series of licensing agreements…to make and ship derivative products based on the intellectual property in UNIX. This forms the foundation for the Solaris OS that ships today."
