The patents, filed in 1994 by Peter Hochstein and Jeffrey Tenenbaum, are specifically for "communicating live while playing the same videogame in separate locations".
Sony recently settled a similar lawsuit with the two men, over the PlayStation Network. The amount of the settlement was undisclosed.
