You can make a John Carter Of Mars story without the Burroughs estate, but you have to go out of your way to make sure
>it can't be mistaken for something made by the burroughs estate
>that it doesn't include any character or plot element in the books that aren't public domain
>You can't use the name 'john carter' in the title of it, or on any of the advertisement

Hence why Alan Moore could get away with using John Carter in League of Extraordinary Gentlemen without Burroughs estate suing him, and why Dynamite Press had to change the name of their John Carter Of Mars comics to Gods Of Mars.
