MPEP Q & A 216: Time for Establishing ISR and WO of the International Search Authority

mpep-podcast-800

Question:

What is the time limit for establishing the International Search Report and the Written Opinion of the International Searching Authority?

Answer:

Publication of the international application occurs at 18 months from the earliest priority date or, where there is no priority date, 18 months from the international filing date. The international search report is subject to international publication.

For international applications filed before July 1, 2014, the written opinion of the International Searching Authority (ISA) is not published but is made available to the public after the expiration of 30 months from the priority date. For international applications filed on or after July 1, 2014, the written opinion of the ISA and any informal comments submitted by the applicant will be made available to the public in their original language as of the publication date.

The Office goal is to have the search report and written opinion mailed in sufficient time to reach the International Bureau by the end of 16 months from the priority date or 9 months from the filing date if no priority claim is made.
