While I'm not aware of any examples of anything building on ancient UNIX 
as a whole,
I would like to note that parts of ancient UNIX have made their way into 
other systems.

For example, FreeBSD and OpenBSD src/usr.bin/diff/diffreg.c are derived 
from Ancient UNIX diff(1) source code, namely 7th Edition UNIX.
(There is some amount of irony in Xinuos forking FreeBSD and basically 
importing their own licensing issue indirectly.)

Various pieces of documentation under the Caldera license also permeate 
the BSDs.
