What is the internal time limit for the USPTO to prepare the international preliminary examination report?
According to MPEP 1879.01, while the official time limit for establishing the international preliminary examination report is 28 months from the priority date, the USPTO has set an internal deadline:
“This time limit is 27 months internally to ensure sufficient time to process, review and mail the report in sufficient time to reach the International Bureau by 28 months from the earliest priority date.”
This internal deadline gives the USPTO a one-month buffer to complete all necessary procedures and ensure timely delivery of the report to the International Bureau. This practice helps maintain compliance with the PCT timeline and provides applicants with timely information about their international applications.
