Except there was not prior art, the iPad patent was found valid through reexamination and at court
The law/case law is far too loose with the requirements for novelty.
Being upheld by a court does not mean something is a good patent.
Mathematics are not supposed to be patentable at all but people manage to sneak in pure algorithms by gluing them to an arbitrary machine. The system is quite clearly broken.
The only good patent is the one that stands up in court.
The Star Trek PADD is not too far off either.
The patent is bogus to any sane and honest individual.
Apparently it wasn't.
