Thom Kidrin's Worlds.com outfit are in the midst of suing game makers NCsoft, alleging that the Korean giants infringe Worlds.com copyrights through their various persistent universes.

Kidrin says that if the against is successful then his firm will go after Second Life's Linden Labs and - the big daddy of them all - Blizzard.

The executive confirmed proceedings a few months ago, claiming that Worlds.com owns the rights to create virtual, scalable worlds encompassing thousands of players.

Whether the case against NCsoft will actually prove a success remains to be seen - but we imagine and Linden are watching proceedings with intense interest.
