SCO's lawsuit asserts that IBM has breached contractual obligations between the two companies, and also that IBM has incorporated trade secret information concerning the design of the Unix operating system into what SCO calls generally &ldquo;Linux.&rdquo; This latter claim has recently been expanded in extra-judicial statements by SCO employees and officers to include suggestions that &ldquo;Linux&rdquo; includes material copied from Unix in violation of SCO's copyrights. An allegation to this effect was contained in letters apparently sent by SCO to 1500 of the world's largest companies warning against use of free software on grounds of possible infringement liability.
