She did try to speak scientifically as below:
Du's own words, "In light of the statistically significant differential effects..."
But wrong interpretation.
Even if she as judge does not have to be scientific (district judge for patent litigation should, imo) , does not mean she can be wrong, if wrong, has to be corrected.
This moment, she was not a POSA, instead, a judge, right? Getting a bit dizzy now. But glad we made some progress today.
