In January, it was revealed that Nintendo had registered 39 trademarks corresponding to its licenses. Among these was Mario Sports, which is brought into the limelight again today.
Indeed, a quick look at the EUIPO (European Union Intellectual Property Office) website will reveal that the Mario Sports brand had recently been registered by Nintendo. More specifically, a prior deposit was made on May 14, but when clicking on the associated link, we discover that the entry was updated on July 16, and updated again the next day, which hints at a possible released on the Nintendo Switch, or on mobile devices. At the moment, Nintendo has not announced any titles dedicated to the license, the last of which date from 2011 on Wii, with Mario Sports Mix, and 2017 with Mario Sports Superstars on the 3DS.
