The substantial new question of patentability standard is lower than the prima facie case of unpatentability standard needed for a patent examiner to make a valid rejection. In other words, just because a prior art patent or printed publication raises a substantial new question of patentability does not necessarily mean that the prior art patent or printed publication can be used either alone or in combination with the other art of record to reject the claims. Nevertheless, it is most common that a reexamination when ordered will result in the claims all being rejected. Thus, in the clear majority of cases a reexamination request is granted if the request will support a prima facie case of unpatentability.
