Hi,
I've read this topic but I need some information and clarification.
You're saying that stories, not the characters, are subject to copyright.
Again, you're saying that a copyright can be renewed (I remember that the recent case about Shuster's heirs, that have reacquired some rights on "Superman", is due to DC un-renewing the copyright).
Here starts my questions:
-the copyright ends, and the PD starts, after 70 years from the death of the last author (if there are more than one), so why there is the need of a renewing? 70 years from death should be the only reference. For instance, ERB is dead in 1950, so his stories should become PD in the 2020, but only those he wrote, because the derivative ones have (or should have) different property (like the Kubert comics for DC... if they are property of Kubert);
-some works are in PD because the author is dead from more than 70 years but its main character (Conan stories by Howard) has a trademark (so states Conan Properties in his website) but his stories should be usable. At the same time nobody should be enabled to make a new story or a derivative one (like a comic-book version of the same Howards' tales) but can print the original tales. Well, due to the trademark, he should delete every "Conan" from the titles, what do you think? ;
-when the property isn't of the author but is of a company there are different rules? For instance, Hulk when will be PD ? 70 years after the death of Jack Kirby and Stan Lee?
Thanks everybody.
DT
