Yes it was. According to Groklaw, Samsung has already pointed the re-examination results out to the court, as this patent made up a solid chunk of the infringement the jury found, and hence the damages number presumably needs to at the very least be adjusted. However, the jury didn't indicate how they apportioned the number, so this might be another way for Samsung to get a new jury trial on at least parts of the issues.

Yeah, I had the same thought ... but multiple sources are reporting that it was one of the patents at issue in the trial. I think it's not a generic "pinch to zoom" patent but specific logic for distinguishing a pinch to zoom from other gestures.
