Nintendo has filed for a new trademark for the Mario & Luigi brand, despite the studio that develops the series - AlphaDream - having closed last year. Reported by LetsGoDigital (via Eurogamer), Nintendo of America has filed for the new trademark in South America through the Argentina trade mark office. [ignvideo url="https://www.ign.com/videos/2016/01/20/mario-luigi-paper-jam-video-review"] The description attached to the filing includes notes of “computer game cartridges; game memory cards; computer game software; video game memory cards; interactive entertainment software to play video games; covers for mobile phones”, indicating that it covers pretty much everything that could come out of the Mario & Luigi brand. The Mario & Luigi games are RPGs developed by AlphaDream. The series’ future was put into uncertainty last year when AlphaDream filed for bankruptcy and was forced to close. Since then, Nintendo has made no official comment on its intentions for the RPG series, so fans have been uncertain as to if there would be more games. This trade mark filing could indicate plans for further releases, or could simply be an act to re-secure the trademark if it were about to lapse in South America.

Last year saw the releases of Super Mario Maker 2, Luigi’s Mansion 3, Mario & Sonic at the Olympic Games Tokyo 2020, among others.
