In January, the Square Enix terms "HD-2D" and "HD2D" were trademarked in Europe. These terms were used by the Japanese developer and publisher to describe the graphical aesthetic featured in last year's Switch exclusive, Octopath Traveler.
Square Enix recently followed this up by filing a couple of Mana trademarks in Europe. It appears Final Fantasy Adventure and Secret of Mana have now also been trademarked in North America on 5th February 2019.
As noted by Siliconera, Final Fantasy Adventure is the first Mana series entry in North America and goes by the name Seiken Densetsu: Final Fantasy Gaiden in Japan. The sequel, Seiken Densetsu 2 is better known in North America and Europe as the classic Super Nintendo action RPG, Secret of Mana.
Final Fantasy Adventure was last spotted on the PlayStation Vita and mobile devices as a 3D remake called Adventures of Mana. The original version also featured in the Seiken Densetsu Collection for Switch, which was exclusive to Japan. This compilation included Seiken Densetsu 1 to 3. A 3D remake for Secret of Mana also arrived on multiple platforms including PlayStation devices and PC last February. Siliconera suggests it's worth keeping an eye out for what could be a possible Seiken Densetsu 3 trademark in the future.
