I am not talking about statistical significance. And Mori doesn't have to prove anything. My understanding is that Mori said something like: “DHA caused an increase in LDL-C while EPA was different.” If that’s wrong, fine, I’m wrong. It happens. I am not trying to be dishonest here.
I don’t understand your comment about anticipation and obviousness.
I don’t have the time to try to find case law about the point I was making with respect to burdens of proof. I think it is pretty much black letter law, not just for patent law, but for all law. Suppose someone is charged with murder. The state has to prove a number of things: that a murder occurred, that the defendant had means, motive, opportunity, etc. All of the things that need to be proved must, collectively, add up to conclusion, beyond a reasonable doubt, that the defendant did it. But the state does not have to prove each thing, individually, beyond a reasonable doubt.
