If they did, I am sure AT&T would require them to display a copyright notice
to that effect somewhere. However, all their disks, manuals, etc, only show
a MKS copyright.

There are also numerous other examples of people developing functional clones
of UNIX -- including the same names for commands -- without AT&T taking any
action: Regulus, Coherent, Minix, etc.

There are numerous PD programs which duplicate UNIX functionality, and which
AT&T is surely aware of because they are distributed over this network: 
PD Tar, AFIO (a cpio clone), GNU AWK, etc. No action was taken against any
of these by AT&T. In fact, John Gilmore had a letter from AT&T's legal dept.
stating that UUSLAVE, which is functionally equivalent to uucico, did not
contain any AT&T code and did not infringe on their rights.

That's why I am not sure that the CSS case has the impact Dominick hints at
above.

And finally, as I said in my original reply, I heard from someone in the orbit
of the CSS principals that they were almost certain that CSS had had access to
VI source code, and that was right after PC-VI first appeared.

Since ATT&T and CSS settled out of court, there is no knowing what AT&T would
have ended up showing and arguing in court, unless CSS violates the terms of
the settlement and the thing comes to trial after all.
