 For example, when an Examiner sends a restriction requirement, a one-month shortened statutory period applies, and if the applicant sends a response on the 31st or 32nd day (depending on the month, as well as on Saturday/Sunday/holiday practice; note that February is granted 30 days), a petition for a one-month extension, and the associated fee, must accompany the response.Most other Office actions have shortened statutory periods of either two or three months.Note however that an applicant cannot petition for an extension of time beyond the six-month limit.
