See
https://en.wikipedia.org/wiki/UNIX_System_Laboratories,_Inc._v._Berkeley_Software_Design,_Inc.
for a summary (see Pretrial section) and
http://sco.tuxrocks.com/Docs/USL/Doc-92.html for the ruling itself that
discusses the details).

"Consequently, I find that Plaintiff has failed to demonstrate a likelihood
that it can successfully defend its copyright in 32V. Plaintiff's claims of
copyright violations are not a basis for injunctive relief."

being the appropriate quote. Plantif == USL.
