Fogerty was sued for infringing a copyright of a song that he himself wrote. He eventually "won" in the Supreme Court Fogerty v. Fantasy, 1994), in the sense that the judges ruled in his favor. I don't know whether he considers the victory to be worth the disruption of his life and the expense he was put to.

Chet W., it is too strong to say that I am "for" a life-plus-thirty term of copyright. Life plus thirty is about the maximum life-based term for a published work that I am willing to admit is constitutional--assuming life-based terms are constitutional at all for published works, which I consider subject to doubts. But it's true that I consider strictly limited copyright to be a useful expedient to a society which wishes to encourage learning creative freedom.
