Please note that as a result of feedback we received from the PCT applicant and agent community via the PCT User Survey, we have revised the PCT-related pages on the WIPO website, as of June 16, 2025.
In doing so, we have attempted to improve the presentation and layout of content so that visitors can more easily find the information they need.
The changes include the redesign of the main page, the creation of a number of new pages, and restructuring of the PCT content for improved navigation.
At the same time, WIPO has migrated the contents of the PCT pages to a new content management system which will mean that you will need to update any existing bookmarks you may have.
We hope that you will find the revised PCT webpages easier to navigate. Please send any questions or suggestions to PCT Resources.
