Totally kind of unrelated but you reminded me: Mickey Mouse must be up again in 10 years right? Which means they'll probably have to start trying to push something through for an extension pretty soon. Strangely, I'm actually excited to see this go down. I also still don't get why, since characters like that are generally trademarked and can't be used anyway? Like, having Mickey Mouse public domain wouldn't really mean much since he's an enforceable trademark as long as Disney can argue that they still have him in use as part of their branding.
Back on topic....good, what a bunch of assholes I guess. I mean, I can't blame them for trying to hold on to it, but the PR move of letting lapse into public domain would have been brilliant. That said, I don't really know how successful this will be....assuming that they don't hold the copyright and assuming it's through some technical error and not misrepresentation I don't know if you can really sue for paying licensing fees when you didn't have to. I could see it being one of those "Well, you should have probably looked into it a little bit" kind of things.
