Worlds.com VW patents to be enforced?
Virtual Worlds News is reporting that a law firm has been retained to enforce the Worlds.com patents on 3d virtual worlds. These patents are quite old — filed in the early 90s — and center around visibility culling of avatars in various ways.
Worlds owns U.S. Patent Nos. 6,219,045 titled “Scalable Virtual World Chat Client-Server System” and 7,181,690 titled “System and Method for Enabling Users to Interact in a Virtual Space.”
Together the claims describe systems for tracking the spatial relationships of avatars and objects in client/server systems and managing their interactions as well as how many can be displayed at any given time.
It will be interesting to watch what comes of this.
