I think that in itself is a big bargaining chip to restructure the original 1994 movie licensing deal concerning the FF at least.
The only characters I am certain FOX has the rights to use are the ones I have actually seen on the screen. In the case of the Skrulls, I am assuming FOX has some rights to the characters as we've seen Super-Skrull Johnny Storm in the FF sequel.
To me, the big bargaining chip for Marvel is that although a well-made FF reboot will be quite costly, it's difficult to see how a reboot will outgross the $330,000,000 (per Box Office Mojo) earned by the first film back in 2005. With additional revenue streams from merchandise, video games and the like Disney/Marvel likely can justify this risk. I don't see FOX reaching this same conclusion.
