The Elder Scrolls V: Skyrim developer Bethesda Game Studios' parent company, ZeniMax, has secured the new trademark 'Dragonborn' for what could be the second major downloadable content update for the wildly-successful role-playing game.

'Dawnguard' was the trademark secured by Zenimax back in March, and just about a month later, we got the official announcement of the first official DLC pack for Skyrim sporting that very title, which is planned for a summer release. Of course, next to nothing else is yet known about what sort of content 'Dawnguard' will include.

The 'Dragonborn' trademark filing--reported by OXM--may follow the same path, though it's a bit early to say for sure. In any event, it's reasonable to expect we'll hear more news about 'Dawnguard' at E3 next month before we find out much more about what the 'Dragonborn' trademark will be used for, if anything.
