The Japanese Patent and Trademark Office published on OCtober 4th the filing for the registration of the trademark "Luminous Studio Pro" by Square Enix.

The filing was made on September 12th by the publisher within classes 9 (games), 41 (online games) and 42 (design for software), and it's different from the one made back in 2012 for Luminous Studio.

This appears to be the new (and possibly complete) version of the engine that has been in the works at the publisher since the beginning of the decade. It's actually not the first time that we hear about it. In one of the latest "World of Wonders" trailers, the name was displayed towards the end, as you can see at the bottom of the post.

Below you can also check out the full document for the registration.

Many speculated on whether Square Enix is going to keep using the engine after Final Fantasy XV or not, considering that other relevant projects are being created using Unreal Engine 4 (Final Fantasy VII Remake and Kingdom Hearts III). The registration of the trademark could be seen as an indication that the publisher at the very least isn't abandoning the engine, which would make sense, considering the resources that have been spent in creating it.

As usual, we'll have to stand by and see, but now Luminous Studio (almost) officially has a new name.
