What makes this so complex??
  • SCO sued IBM claiming that IBM illegally introduced code from AIX into Linux
  • Existing software business model is based upon notion of proprietary
    • Know and well established model
  • New model: open source and resulting licensing (ASF, GPL, and others)
  • The intersection causes tension
  • SCO started as a Xenix vendor
    • Purchased by Caldera a Linux vendor
    • Chain of custody of the IP is muddy
