On March 30th, 2012, Worlds, Inc. sued Activision over alleged patent infringement. The former accuses the later of infringing on a variety of technologies filed as “System and Method for Enabling Users to Interact in a Virtual Space.”
Essentially, Worlds, Inc. is accusing Activision of violations with regard to Call of Duty and World of Warcraft. Our understanding is that Worlds, Inc. is claiming that it holds the patent for the way servers and user PCs and consoles facilitate player interaction.
Today, Activision has counter-sued claiming that Worlds, Inc.’s product, Worlds Player, infringes on two of its own patents. Those are U.S. Patent No. 6,014,145 (“Navigation with optimum viewpoints in three-dimensional workspace interactive displays having three-dimensional objects with collision barriers”) and 5,883,628 (“Climability: property for objects in 3-D virtual environments”).
Worlds Inc.’s lawsuit is still pending.
