You may want to look at the lawsuit AT&T/Berkeley a couple of years ago.
CSRG has always had the Unix source code available, but they did continously
rewrite parts of the unix kernel and made the code available for everyone.
AT&T (their lawyers anyway :-) said that because CSRG had the AT&T sources
available, the Berkeley code was based on AT&T sources. 
AT&T lost in court. Here are at least an american example of this.
The lawsuit was much more complicated than this, but the big 
point is the same.
