I guess there was a huge legal fight that he eventually won through argument and opponent apathy, so as long as he doesn’t let the character sit completely idle, he keeps the rights despite no longer giving a fuck either. It’s utterly petty, and if I cared more about Dick Tracy I’d probably find it infuriating rather than hilarious.
Yeah and it ran until the 70s, so there will be a lot of legal land mines with using that character for quite awhile.
