Square Enix has trademarked “Final Fantasy Digital Card Game” (2018-154309) in Japan. The Final Fantasy Trading Card Game is a physical trading card game by Square Enix and Hobby Japan. A digital version of the card game does not yet exist.

Additionally, Bandai Namco filed a set of trademarks for a handful of its previously released Nintendo Entertainment System titles:

“Battle City” (2018-152914)

“Warpman” (2018-152915)

“Final Lap” (2018-152916)

“Family Pinball” (2018-152917) (known as Rock ‘n Ball in the west)

“Aratanaru Densetsu” (2018-152918) (the Japanese subtitle to the Nintendo Entertainment System game Dragon Spirit: The New Legend)

It is possible these titles were trademarked for the purpose of joining the Nintendo Entertainment System – Nintendo Switch Online app available to Nintendo Switch Online subscribers.

As a bonus, Bandai Namco Pictures filed a series of trademarks (2018-15531, 2018-15532, 2018-15533, and 2018-15534) for “Battle Spirits: Saga Brave,” which might be the title of the third Battle Spirits anime series announced in December 2017. The 2009 to 2010 anime for Battle Spirits saw the release of two PSP games and a DS game, so it is likely more games will follow for the third run.
