What is the time limit for responding to the Written Opinion of the International Searching Authority?

The MPEP provides clear guidance on the time limit for responding to the Written Opinion of the International Searching Authority. It states: If, in response to the written opinion of the International Searching Authority (Form PCT/ISA/237), applicant wishes to file a demand and amendments and/or arguments, the time period for response is 3 months from the mailing of the international search report and the written opinion or before the expiration of 22 months from the priority date, whichever expires later.

This time limit is crucial for applicants who wish to file a demand for international preliminary examination and submit amendments or arguments in response to the written opinion. It’s important to note that this deadline is based on the later of two dates: 3 months from the mailing of the search report and written opinion, or 22 months from the priority date.
