I find it funny how EA is suing Zynga for IP infringement, just over the look of a game. Even though they copied the exact look of CityVille, for SimCity Social, but whatever. Now they copyright something called "Jet Set." Well hasn't that name been used in gaming by Sega for over a decade now? It might be a totally different game, but still wouldn't Sega have a trademark on the Jet Set name? EA got sued for using the word Edge, so I think Sega would sue over the Jet Set name for sure.
