§366 Withdrawn International Application

Title 35 › Part IV— PATENT COOPERATION TREATY › Chapter 36— INTERNATIONAL STAGE › § 366

Last updated Apr 5, 2026|Official source

Summary

Unless section 367 says otherwise, if an international patent application that names the United States is withdrawn under the treaty or rules before the applicant finishes the U.S. filing steps required by section 371(c), the U.S. designation stops and is treated as if it was never made. It still counts if, before withdrawal, a U.S. or international filing naming the United States had claimed an earlier filing date under section 365(c) or had a claim under section 386(c). If the withdrawn international application named another country, it can still be used to claim priority under sections 365(a) or (b) or 386(a) or (b).
