This method fails in fields where the patent office is explicitly forced to avoid hiring people in that field. So, they cannot reasonably know what prior art might be in that field, if for example they are not allowed to hire anyone with a CS degree, for example. Yes, that was the case for a long time. Only recently have they been allowed to hire patent examiners with CS degrees. So, yay -- fucked up USPTO, as per usual.
