That part of it is not really a rumor; he gave several interviews where he explained in detail exactly how he influenced the jury. All that remains is to see whether or not those statements actually invalidate the verdict.

But in case it's not clear, I completely agree with you: a panel of patent experts would have been even worse. The problem in this case was the judge trusting this guy when he said he wouldn't let his previous experience as a patent holder color his judgement.
