Uh...the patents that were upheld included pinch to zoom, double-tap to zoom, and a grid of icons.
This has a lot to do with a lot of things.
Very true, one thing that really bothers me about all this documentation that was shown to the jury was that it always contains a picture of the Android device's App Drawer or a home screen completely filled with app icons. For those that don't / haven't used Android this is not the default home experience. I think Samsung should have had the opportunity to show devices with Widgets, live wallpapers, etc. - they look a lot different under those (more typical) circumstances.
That said there was obviously some copying of the trade dress going on, especially with the first Galaxy with the single home button. On the other hand the trade dress stuff is way too vague if an Epic 4G (which has a slide-out QWERTY) was found to infringe it.
I also think (from reading the juror interview) that it doesn't sound like they really spent an appropriate amount of time debating the prior art arguments for the Touch Screen, Pinch Zoom, etc. patents. In fact I find it hard to believe they spent enough time on most of the items given how complex this trial was and the relatively short deliberation time.
