Simply because their patent is broad and covers many different scenarios doesn't invalidate it. In fact, the patent was granted. All I'm saying is that the "narrower claims," which apply to Amazon and deal with encrypted ebooks sent to a reader via a phone network, don't appear obvious to me. My guess is that Amazon has something to worry about here, and damages for patent infringement are really nasty.
