That only works if there are books titled “Dragon Slayer” that came about as a result. But since there are plenty of recent books so titled, it’s a bit superfluous.
Oh, that just naturally comes about once they have the trademark. I mean, it may be specifically for “Dragon Slayer” but anything with “dragon” or “slayer” in the name might get confusing for people, so they’ve got to threaten legal action over those, too!
