to this readership, that SCO has played fast and loose with the concept of "ownership" of the Unix IP, deliberately misleading investors and potential corporate "customers" for their "Linux IP license". McBride claimed in several interviews that SCO "owned" the entire UNIX Operating System, period. In fact, they own nothing of the sort; The Open Group owns the trademark and the specification, and has said repeatedly that the spec allows multiple independent implementations of the published APIs. Novell owns most of what's left of the System V patents, AT&T owns copyright on some published documentation (such as Maurice J. Bach's book on System V architecture), while lots of the System V source code is apparently in the public domain thanks to the AT&T v. BSDi case. IBM, Sun, and HP own the copyrights on their extensions and modifications to the System V source. And so forth.
