Article 13 Part 2
So depending on how old or how deep of a Batman fan you are, you probably know who Bob Kane and Bill Finger are, (if not, they are the co-creators of Batman). Of course you know Batman was originally created as a character for comics. Batman was not exclusive to this medium however, and eventually, let's say, they, under DC Comics opened the rights "in fair use" to companies like Warner Bros. and of course, the general public. (In other words, right now you're not going to get sued for drawing and posting Batman fanart).
But what if Bob Kane, Bill Finger, and/or DC Comics in general wanted to keep Batman to themselves and their comics? So much so that they could make a law which states any person or company who didn't officially work for them could not creatively do anything with Batman?
