The busy folks over at have been working hard on copyrighting with them trademarking four new titles.

Unfortunately, we only have names, which were uncovered with a bit of digging by Superannuation.

The four titles that Sony now has trademarked are: Digi-Tiles, Earthshield, Smashbreak and Legend of Kunoichi.

Some may be upcoming titles for the PS3's new motion sensitive controller, which may or may not be called the Gem. This is a name that has been accidentally mooted by some executives but is officially denied by Sony, for now.
