Nintendo of America has applied trademarks for Eevee, Poke Ball, and Pokemon Quest in the United States on May 29, 2018.

That is a day before the official announcement of Pokemon Let’s GO Pikachu/Eevee and Pokemon Quest for Nintendo Switch. Eevee should have been trademarked due to Pokemon Let’s GO Eevee, Poke Ball for the Poke Ball Plus, and Pokemon Quest for the game itself.
