A 2002 e-mail suggests that an investigation commissioned by The SCO Group failed to produce any evidence that Linux contained copyrighted Unix code.
The e-mail, which was sent to SCO Group CEO Darl McBride by a senior vice president at the company, forwards on an e-mail from a SCO engineer. In the Aug. 13, 2002, e-mail, engineer Michael Davidson said "At the end, we had found absolutely nothing ie (sic) no evidence of any copyright infringement whatsoever." The e-mail was posted Thursday to Internet law site Groklaw. SCO sued IBM in 2003 for more than $1 billion, alleging that IBM had misappropriated Unix technology to which SCO claimed intellectual property rights.
