Question Regarding the 2011 Marvel/Sony Contract

[Dominick1216]

I was reading the Sony/Marvel contract back from 2011 and one thing that caught my eye was:

“Kingpin” and related characters listed on the attached Schedule 7B, but SPE may not use any of these until after Fox’s production rights to Daredevil expire. Marvel’s use of Kingpin is restricted to use in connection with Daredevil and other characters with which he appeared prior to 9/15/11.

What I don't get from that is what do they mean by "other characters?" Other characters with which Kingpin appeared with? And if so, can Marvel use him in Spider-Man projects if they ever wanted to?

They certainly can now, as that Fox deal expired not long after that, which is why the Netflix Daredevil show could happen. Even if Fox did still have the DD rights, Disney would've got them back yesterday.
