A Duodecim Prologus trademark leaped out at us like a sharp kick to Sephiroth’s face during a US trademark search.
Just like the European trademark, its registered by Square Enix for use with video game software too.
Square Enix already registered [duodecim] in North America and announced the Dissidia prequel’s name as Dissidia 012[duodecim]: Final Fantasy so we’re a bit puzzled what Duodecim Prologus is. Whatever it is, it’s important enough for Square Enix to trademark in multiple territories.
