The response time in ex parte reexamination is generally shorter than in regular patent examination. In ex parte reexamination, MPEP 2263 specifies: “A shortened statutory period of two months will generally be set for filing a response to an Office action in an ex parte reexamination.” In contrast, regular patent examination typically allows a three-month period for response, which can be extended up to six months.
