Apple
Is it just me or does almost every story about Apple filing a patent involve Apple filing patents for things that are already available? Don't they ever get their own ideas? Heck, there is a video somewhere (I think it was shown on El Reg first) of an iPhone in Japan, going into a "mall" and every store popping up location based services, right down to menus and price lists (and being Japan you can use your mobile there to buy stuff in a store)
