The jury can only decide based on the facts before it. NO PRIOR ART was presented to them. They argued about how that seemed weird. Then they decided that the discussion, which could serve no purpose anyway because they still wouldn't be able to decide based on prior art they were never given, was taking too long. So they moved on.
I don't know where you're getting that idea from. There was definitely prior art presented during the trial at least on pinch to zoom, tap to zoom and the bounceback on scrolling.
