On March 7th 2003, the SCO Group filed a lawsuit against IBM for misappropriation of tradesecrets and contractual agreements. The scope of SCOs complaint is that IBM introduced parts of Unix System V and Project Monterey into the Linux kernel. Project Monterey was a effort to port IBM's AIX 5L onto the Intel Itanium platform, IBM withdrew from that project for reasons unknown according to the press, I believe that it was because the Itanium is a bomb.

I wonder if IBM regularly conducts, or has ever conducted, IP audits of Linux, comparing it with UnixWare and other proprietary code bases they have access to. There are supposedly tools that can find similar or identical sections. I would think they at least would have used this kind of tool after SCO sued them. Maybe IBM did find the 80+ similar lines of code and decided that they weren't the culpable party, or that it wasn't infringing at all (because both lines originated with BSD, etc).
Netscape claimed to have used a source verification tool to ensure that none of their code came from Mosaic, when they were being sued by UIUC.
