The foreman in the Apple/Samsung trial doesn't understand 'prior art'

The foreman in the Apple v. Samsung trial has now done an interview with Bloomberg News, giving him an opportunity to answer some of the criticisms of the verdict. It's a video on YouTube, titled "Apple Jury Foreman: Here's How We Reached a Verdict", and while he answers the criticisms, he describes how the jury, under his instructions, decided that the Samsung prior art didn't invalidate an Apple patent. In doing so, I think he has revealed the biggest mistake of all made by the jury, one so large I don't believe it can be ignored. At a minimum, Apple shouldn't want to win like this. His aha moment, as he calls it, and assuming what he says on the video is accurate, was based on a misunderstanding of what constitutes prior art.

In discussing the first patent on the list, he says they got into a discussion about the prior art that was presented at trial. Here's why they discounted it:

"The software on the Apple side could not be placed into the processor on the prior art and vice versa. That means they are not interchangeable. That changed everything right there."

That isn't disqualifying for prior art. It doesn't have to run on the same processor. It doesn't have to run at all. It can be words on a piece of paper.
