I was trying to understand who can decide in Dragon Ball what's canon or not. You might think it's Akira Toriyama, but as long as the trademark doesnt belong to him, it isnt so. I know it wasnt so with other creators of other animes. Looking in internet, I've found this https://trademarks.justia.com/756/58/dragonball-75658049.html , which mentions Toei (Anime) Shueisha (Manga) , but it isnt clear if the trademark it is owned by Toei or Shueisha? Can anyone clarify?
