There has only been one copyright extension that affected Mickey Mouse that Disney might have had a role in. That was the 1998 Copyright Term Extension Act There was one other copyright extension that affected Mickey Mouse but that one, as far as I've been able to tell, Disney played no significant role in. That was the Copyright Act of 1976. I have little doubt that Disney was in favor of the 1976 Act, but so was almost everybody else. That's because the 1976 Act was a major rewrite of US copyright law to take into account the massive technological changes that had happened since the 1909 Act, and to make US copyright law more compatible with the Berne Convention so that the US could join (which happened later with the the Berne Convention Implementation Act of 1988).
