"On Christmas Eve, South Korean game developer NCSoft received a lawsuit in its stocking from a Massachusetts firm that claims to hold an extremely broad patent for developing online virtual worlds. The legal complaint from Worlds.com alleges NCsoft infringed on its patent for a "system and method for enabling users to interact in a virtual space." The lawsuit fingers nearly all of NCsoft's catalog of massive multiplayer games sold in the US, including City of Heroes, Guild Wars, Tabula Rasa , Lineage, and Lineage II."
