Worlds.com to Sue Blizzard, Linden Lab?
If Worlds.com is successful in its lawsuit against NCsoft, it plans to target World of Warcraft and Second Life, according to The Business Insider. Worlds.com owns a patent for a "System and Method for Enabling Users to Interact in a Virtual Space" - a patent which it claims NCsoft's MMOs violate.
Worlds.com CEO Thom Kidrin told The Business Insider that should the company be successful in suing NCsoft, it will pursue "anyone who refuses to enter into licensing negotiations", including Activision Blizzard and Linden Lab.
