No trademarks could be found on the j-platpat (Japan Platform for Patent Information) website for those three types for Nintendo, Creatures Inc. or Game Freak.
The Pokémon types that the three companies are trying to trademark aren’t based off the video game series, but the trading card game.
Nintendo, Creatures Inc. and Game Freak have jointly filed trademark patents for Pokémon types with the National Center for Industrial Property Information and Training (INPIT for short), on June 5.
