The CEO of Worlds.com, Tom Kidrin, has stated that if his court case against NCSoft, the maker of MMOs such as Guild Wars and Tabula Rasa, is successful he will follow it up by suing other MMO developers like World of Warcraft's creators, Blizzard Entertainment.
Kidrin claims that his company, Worlds.com, owns the patent to create virtual worlds, dating back to the 90s. He claims his company came by the patents via Starbright World, part of the Starlight Starbright Foundation. Starbright World is an online world developed for seriously ill children, and is seen as a "private wonderland" for them.
