SCO chief executive Darl McBride claims that <A HREF="http://news.zdnet.com/2424-9590_22-199987.html?tag=nl.e550">Linux is a copy of Unix,</A> which is contradicted by the open-source community and apparently runs counter to other SCO testimony.

SCO sued IBM in 2003, claiming that the IT giant had used copyright code from the Unix operating system which SCO sold, and later extended this suit to other Linux vendors. However, last August, Judge Dale Kimball ruled that Novell, not SCO, owns Unix. A four-day court case is now determining Novell's claim for up to $20 million in royalties from SCO, which declared Chapter 11 bankruptcy last year.
