Hi, the designer here. As for the font name, Microsoft owns "Comic Sans" but not "Comic" or "Sans" alone. And as already explained, fonts are copyrighted as software codes and a new one has to be made from scratch (except of course when you are the owner or permitted in license agreement). In terms of visual similarity, Comic Neue is much closer to Comic Sans but MS hasn't done anything with it. If that's fine, Comic Code surely would be too. In any case, I did speak with the MS guys prior to release, and they saw no issues with either trademark or copyright.
