Some of you may recall our reports on the 3DS download Pokémon Tretta Lab, an app in Japan that mimics Tretta arcades. These are Pokémon battling games that require collectible plastic discs, which are detected by a reader and turned into a 'mon on screen. In the case of the arcades winning a battle awards more discs, and we imagine the little plastic pieces provide plenty of revenue in a "collect'em all" industry.

It looks like The Pokémon Company may consider bringing this franchise to the West, as fresh U.S. trademarks have been submitted for Pokétretta Battles and Pokétretta Tournament, which speak for themselves. Even if the arcades don't come to the West, it's not beyond the realms of possibility that the discs and bulky 3DS add-on (pictured) could journey outside of Japan.

Two other trademarks have also been dug up by SiliconeraPokéfigure Arena and Pokéfigure. Perhaps these will be related to a game with more NFC toys, or like any trademarks could be placeholders in case prospective ideas come to fruition. These discoveries follow hot on the heals of Pokkén Fighters and Pokkén Tournament, which we'd love to be linked to a possible Wii U Pokémon fighting game though, of course, that's merely speculation.

If these trademarks do eventually lead to some extra games, would you be interested in the Tretta Lab concept coming to the West, or more NFC shenanigans? Let us know in the comments below.
