He could file a petition to establish paternity, legal decision-making and visitation. If that happens, you can raise the fact that he has known of the child and failed to establish a relationship with him. He might counter that he was not given the opportunity, however the fact your son also does not have a bond with him means before visitation could be established, he and your son would need some kind of therapeutic intervention to help establish a bond/work out abandonment issues, etc.
