The studio head was asked how the company will protect the legacy of creators including Bill Mantlo and the late Jack Kirby in an interview with Moviefone.
Feige declined to address the issue how Marvel will "protect" those creators, but promised that everything is done to credit them.
"Well, it's a complex question, but I will say that [Marvel chief creative officer] Joe Quesada and [Marvel Comics publisher] Dan Buckley will take the lead on a lot of that and they are actually quite, quite good in acknowledging and letting us know as we share the scripts and character lists with them [by saying]: 'Here are the creators of this. Here is where they are. Here is who they are', and figuring out what we can do in terms of recognition," he said.
"If you look at the special credits sections of all the Marvel Studios movies, you'll see lots and lots of names, probably half a dozen or so, that apply to even the small characters, much smaller than Rocket, that are included in the movie.
"In terms of Kirby, I always thought of the Thor movie as one of the biggest testaments to what Kirby did because at every turn with the production design, we wanted to embrace it. The helmet design, those horns on Loki. 'Do you really want those to be that big?' 'It's gotta be that big'. I love that stuff, it's tremendous."
The Avengers movie caused controversy by downplaying the role of Kirby in its press and marketing, leading to rumours that he would not be credited in the film.
Mantlo - who was injured in a hit-and-run accident 20 years previously - has been struggling to pay his full-time healthcare bills.
His creation, Rocket Raccoon, will feature in Marvel's upcoming Guardians of the Galaxy movie.
