Have you ever been on a jury for criminal case? It's not like Law and Order where the evidence is that clear cut.
Having been on a federal jury for a gun running charge, I can't even begin to describe how difficult that moment is when the future of someone's life is in your hands. I think the maximum penalty was only 7 years, but even that is enough for you to question every shread of evidence both sides presented.
The difference is that in a criminal trial, if the evidence is not that clear cut then the decision is easy: acquit. Criminal trials require proof beyond a reasonable doubt, and a unanimous verdict. Civil suits only require a 'preponderance of evidence' and only a bare majority of the jury. It's far more wishy-washy, and in a patent suit like this one the issues are far more complicated.
