the Marvel rights thing's complex, but what it basically boils down to is; Spider-Man stuff is with Columbia. Daredevil, Elektra, X-Men and Fantastic 4 is with Fox. the rest is with Marvel.
where there's overlap, like the Bugle and Ben Urich, it gets complicated. The Bugle is part of Spidey, but Urich was in Daredevil and he worked for another fictional paper.
theoretically, the X-Men could fight Doom, Daredevil could fight Magneto and the F4 could fight Kingpin, but i can't see that happening.
