I am quite sure the jury is going to concentrate on the patents and infringement at the trial
I am shure the lay jury with no technical background relevant to the case will be concentrating on the highly technical matters of validity and infringement.
Not.
Is your quite sure-ness based on personal experience with juries on highly complex art patent trials in the USA?
Which ones?
BTW, that is why patent cases go to the CAFC on appeal - those judges are at least reasonably competent to examine these complex issues. No jury verdict in favor of a plaintiff in patent case means much of anything - the CAFC is the important step.
But if the jury finds against the plaintiff, then in almost all cases, that is it - case over. A plainiff appeal of a jury verdict shutout can be attempted on certain limited procedural issues, but it is usually a lost cause for a plaintiff whose claims have been rejected by a jury. It can be done, but that is Mount Everest to climb for a losing plaintiff.
