it appears that Apple's designers and patent staff simply used the Where To? screenshot as an example of an interface a user might find when entering an airport, without claiming any invention of the interface's design itself or even the functionality behind it.
so if they didn't design the interface, and haven't worked out how the functionality would be accomplished under the hood, what the heck are they patenting, the idea? nobody really owns ideas. if you want something secret, don't tell anyone, and if you want market exclusivity, implement it better than your competition (also don't rip them off). patents have become a joke.
say: i have an idea for this big sphere of fire hovering in space which may or may not already exist but would consequentially cause other non-flaming spheres to revolve around it and be illuminated and maybe burned and would generally make life possible on one or two. haven't worked out the details yet but r&d tells me that it might involve gases or whatever and something called fusion? doesn't matter. anyway i thought of it first and i'm submitting my "proof" so's nobody else can waltz along and claim it, even if they took the initiative to work their ass off on the details of a "stolen" idea and make it a reality out of the goodness of their heart in their basement over a weekend...
