1. The right to full ownership of what we fully create.

This means copyright and trademark. The term fully create is open to debate. Siegel and Shuster fully created Superman in my view, regardless of how much editorial input they may have received. It was their idea. Had they retained ownership of Superman from the start and later hired others to create stories for the character, such as DC Comics has, those other would be entitled to many rights, but ownership of Jerry and Joe’s characters would not be one of them.
