Silicon Graphics Inc says that it has received notice from SCO Group Inc that the Unix vendor intends to terminate its Unix System V license on the basis that SGI has breached the terms of the license.
The move by Lindon, Utah-based SCO is the latest twist in its long-running claims that code from its Unix System V has been copied into the Linux operating system. The company has also terminated the Unix licenses of IBM Corp, sued IBM for $3bn for breach of contract and misappropriation of trade secrets, and maintained that Linux users need to license its Unix intellectual property to avoid potential litigation.
