Level-5 has filed a trademark for both the titles "Black Market" and "Akihabara Black Market," which could mean that the developer of Dark Cloud and Professor Layton might be working on a new game based in the shadier parts of Japan's real-life Akihabara "Electric Town" district, well known as a haven for gadgeteers and fanboys. You might remember the area, as we do, from being immortalized in video game form in the great The World Ends With You.

Level-5 also filed a (probably unrelated) trademark for something called "Cyberanimals." These could be the titles the company is working on with Capcom, and/or they could represent projects planned for the 3DS next year. We'll have to wait and see.
