Patents threaten virtual worlds, MMOGs
Any person who "invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent," subject to the conditions and requirements of the law. So says the US Patent and Trademarks Office (USPTO), citing the applicable statute. There's a lot of slicing, dicing and hair splitting over nearly every part of that sentence, and some extraordinary debates and numerous calls for reform of the patent system. Nevertheless, today we're looking at two patents that the owners appear to be keen to enforce. Between them, they appear to cover a few simple, and difficult-to-avoid systems that underpin pretty much every graphical virtual environment, and MMOG that you can think of, from World of Warcraft, to Second Life -- and perhaps most of the online multiplayer games since the era of Doom.
