Square
patented the ATB system when they created it, so I think it's entirely possible that someone
could have patented the systems used in an MMORPG. But I don't think that's what this company has the patent for, and even if they did have the patent I doubt that the system would be exactly the same in a different MMORPG anyway. Seems like an attempt to get something out of the MMORPG surge going on right now, to be honest.
