The United States Patent and Trademark Office (USPTO) is implementing the PCT Informed Examination Request (PIER) Pilot Program. This pilot program is designed to assess the impact on inventory and efficiency when requesting examination in view of applicable PCT international phase work products.

The USPTO will select certain national stage patent applications for the program. When an application is selected for the program, the USPTO will issue a requirement for information referencing the applicable international phase work products and require the applicant to indicate whether they opt into one of three options: proceed with examination (with the option to place the application in better condition for examination by filing a preliminary amendment), delay examination, or expressly abandon the application in view of the international phase work products The applicant must respond to the requirement for information using USPTO form PTO/SB/478 to avoid abandonment of the application.

The USPTO expects that this program will help efforts to reduce inventory and pendency. More details can be found below and in the 2026 Federal Register notice for the program.

The pilot runs through April 9, 2027.
