SCO knew that there was not enough of its code in Linux -

Groklaw has found evidence that the anti-Linux bad-boy SCO knew that there was no Unix under the bonnet of Linux long before it began its long and fatal court battle.

A consultant was hired by SCO in 2004 to compare UNIX and Linux in the hope that what he could find would be used in the planned court case.

But Bob Zeidman said that, after days and days, his comparison tool found "very little correlation".

He told SCO and they paid him off and he never heard from the outfit again. It seems that facts did not stand in the way of SCO and it went on to sue people for alleged copyright infringement anyway.

Zeidman has just written a book called "Software IP Detective" in which he tells about how he was using a CodeMatch tool for measuring source code correlation.

It was fairly new at the time and if he could use it to prove that SCO Unix was under the bonnet of Linux he would have made a killing.

The comments back up other code comparisons that were done at the time by others.

"SCO attorneys gave me some code samples from SCO UNIX and Linux to compare. CodeMatch chugged along for days before generating a report showing very little correlation," the Groklaw author said.

Groklaw points out that this means when SCO began its copyright infringement claims against IBM, Novell, AutoZone, and the world, it knew that it had no case.

If they deliberately buried that evidence, SCO's victims would be able to ratchet up the damages.
