What the prior art taught is at least in part a subjective inquiry, as is confirmed by the fact that parties hire experts in the field to opine on what was taught by the prior art. If it was not in part a matter of opinion, there would be no reason for experts to opine. Expert testimony is only allowed if it is helpful to the trier of fact in deciding factual questions outside the ken of an ordinary bloke.
