Warner Brothers would have your ass first for violating their copyright on Tom and Jerry.

Also: Nintendo has gotta be the shittiest patent trolls ever. Like, I am used to hearing about the kinds that just patent a fuckton of random shit that does not already exist in the hopes someone actually invents the thing; but Nintendo has been applying for patents for things that already exist and are done by hella people, just to litigate their competition to death recently.
