GPL, rev 2 (written in 1991) says in its preamble:
+Finally, any free program is threatened constantly
+by software patents. We wish to avoid the danger
+that redistributors of a free program will
+individually obtain patent licenses, in effect
+making the program proprietary. To prevent this,
+we have made it clear that any patent must be
+licensed for everyone's free use or
+not licensed at all.
I did a quick grep of the word "patent" in
rev 3.0 of CC-SA and couldn't find any mention
of the word.
