How does the IPEA obtain a copy of the priority document in PCT applications?
This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
The International Preliminary Examining Authority (IPEA) can obtain a copy of the priority document in PCT applications through several means. MPEP 1870 outlines the process:
“If the International Preliminary Examining Authority needs a copy of the earlier application whose priority is claimed in the international application, the International Bureau shall, on request, promptly furnish such copy.”
Additionally, the IPEA may already have access to the priority document if:
- The earlier application was filed with the IPEA in its capacity as a national Office
- The priority document is available to the IPEA from a digital library in accordance with the Administrative Instructions
If these options are not available and the applicant fails to provide the document, the examination may proceed as if priority was not claimed.
