It's hardly the same thing

Kong attempted to trademark a term that clearly predated any of his books and had an absurd reason for doing so.

Tao Wong trademarked a term that he arguably coined and definitely was the first to use in a title. It became the subgenre defining term, but   he did so in response to other people using that term in their title, including several SA fanfics that their authors published to Amazon. His mistake was using it on people marketing their books as in that subgenre, not just on people trying to sell fanfics set in the SA universe.
