What kinds of intellectual property does SCO claim in Linux?
SCO owns no relevant patents, nor does it claim to. The Open Group owns the trademarks for “UNIX” and “UnixWare”. The complaint filed by SCO makes only a passing reference to alleged copyright infringement, and that reference does not attribute any infringement to IBM specifically. Indeed, SCO has stated that the filing against IBM is about breach of contract, not about copyrights. What’s left is trade secrets — information that one or more parties are under contract not to disclose.
