the original claim 1 [...] had not claimed a computer. The examiner correctly issued a rejection, saying the claim was abstract and thus wasn’t something that could be patented. In response, the applicant added element (g) (“providing a computer, the computer performing steps “a” through “f””). And the rejection went away. I see this happen in peer-reviewed research. A reviewer rejects the paper/patent based on a flaw that is perhaps not as gross but is at least concrete. When the flaw is removed (in this case the use of computer), the reviewer almost has no choice but to accept it. Can't the reviewer reject it for other reasons?
