Activision files virtual worlds patent countersuit against Worlds Inc
Activision recently filed a countersuit against Worlds Inc over two patents related to virtual world interactions. The lawsuit is in response to one filed by Worlds Inc against Activision on March 30 regarding its patent "System and Method for Enabling Users to Interact in a Virtual Space." The two Activision-owned patents in question, "Navigation with optimum viewpoints in three-dimensional workspace interactive displays having three-dimensional objects with collision barriers" and "Climability: property for objects in 3-D virtual environments" are included in Worlds Inc software called "Worlds Player," Activision alleged. Worlds Inc settled one suit against NCSoft in April 2012 after citing similar patent infringement in its games. As of March 2012, the software developer's news site noted that it has been awarded six patents in the United States related to virtual worlds, and it also holds one "'notice of allowance' for a seventh patent for multi-server technology for 3D applications."
