SCO is the thief who puts a gun to his own head and says give me your money or I'll shoot.

I haven't read the filings yet, but it sounds as if SCO's main claim is that IBM (and perhaps others) violated their non-disclosure agreements by allowing employees who had seen the Unix source code to work on Linux. However, Linux was developed first on the Intel i386 processor family, way back in 1991, at least five years before IBM took an interest in it. Linux follows MINIX, an even earlier published-source-code system that very clearly isn't derived from Unix – its architecture was very different.

SCO claims that Linux could not have become ready for the enterprise so quickly without use of art originating in Unix. They seem to ignore the fact that hundreds of thousands of people have been educated in operating systems programming, and that very healthy communities of scientific research exist for systems design, and that most of the enterprise-ready features originated in research operating systems and only later were ported to Unix.

They claim that the Linux libraries could not have been produced without input from Unix. But these libraries are written to a printed specification called POSIX, published by the U.S. government and available to the general public. The GNU C library, and many other Linux libraries, existed long before IBM's involvement. We also had printed “man pages” for Unix available in bookstores without restrictions on implementation of the documented facilities, and shelves of published documentation on Unix in every technical bookstore.

So, I think the claims I've heard are specious, and not enforcible in court. Why, then, is SCO doing this? They want to be purchased. This is the exit strategy for their investors, Canopy Group. IBM can buy them just to shut them up. Or Microsoft can buy them to use them to FUD Linux. And Canopy Group management figures they'll play the two against each other to drive up the price. But IBM management is smart enough to poison this particular well, by bringing counter-claims against SCO.

SCO is also party to the GPL, which invalidates their patent portfolio for any of their patents that happen to have been used in a Linux system that they distributed. Under the GPL terms, if you distribute your patented practice in GPL software, you must grant a license to everyone to make use of that patent in any GPL software, for any field of use. This is why SCO's initial claim seems to be focusing on an NDA rather than patents. And of course, the fundamental patents that apply to Unix would have expired some 15 years ago.

SCO can't claim that IBM (or anyone else) was hiding the Linux development from them, since Linux source is available and is part of SCO's own Linux product. They have been distributing the source code that they claim violates their own NDA as Caldera's main product for years. So, they are going to have a very small chance of making this case work.

We in the Free Software developer community must make it clear that we will not tolerate specious intellectual property claims on our software, even if those claims are directed to a user or industrial partner rather than an individual developer. The obvious first step that would occurr to any of us would be to shun SCO – not to do business with them, not to recommend them in our jobs, etc. SCO must have known that they'd be shunned for these shenanigans, and they went ahead with them anyway. This means they're writing off their entire software and operating systems business. SCO is owned by Canopy Group, I guess those folks are writing off their other software businesses, too.

I look forward to getting a look at the court papers, and being a witness for the defense or amicus curae in these cases. I'm sure I'll be joined by a lot of you. In addition, we may have our own infringement claims to make, if the SCO filing violates the GPL terms. I doubt there will be much left of SCO at the end of this.

These folks could have been good partners. Other people in industry were, and beat Caldera and SCO in the market. Canopy Group, their venture firm, were the real managers of SCO and Caldera. Front-men like Ransom Love were not the ones making real decisions. Their business failed, and others flourished, because Canopy Group never understood how to be our partners. They've chosen to screw us one last time on the way out the door. Let's do our best to turn it back on them.
