That is what keeps UNIX a trade secret. Certainly, UCB can add their own restrictions for their enhancements ON TOP of AT&T's. For a UNIX look-alike to be free of AT&T ownership, it would have to be developed entirely from publicly available information. Although this covers a lot of ground, that is still so much work that only a few vendors offer such systems, and they are hard put to track newer developments of the "official" UNIX product.
