Sony Ericsson has filed a rather interesting patent in India: for “a method and an apparatus” that allows gamers to switch between devices, without losing their place in the game. Essentially, this is an invention that makes the game platform agnostic. The player can pause the game, and switch from, say, a console to a mobile device, and similarly switch from the mobile device to the console.

Given that much of mobile gaming is still centred around single player casual games, I think the games will have to be pretty basic for this to work. Something on the lines of street figher, bounce, or perhaps even a racing game. It’ll work best for turn-based games like Chess, since the games will be hosted on an online network, so the bandwidth will have to be pretty spectacular. Perhaps this is one of the applications planned for 3G.
