What form should I use to withdraw my international patent application or designations?

To withdraw an international patent application, designations, or priority claims, you can use Form PCT/IB/372. This form is mentioned in MPEP 1859 and is designed to comply with the requirements of PCT Rule 90bis.

The MPEP states: “Form PCT/IB/372 may be used by the applicant to make a withdrawal under any of PCT Rules 90bis.1, 90bis.2, 90bis.3, and 90bis.4. The form is available from WIPO’s website (www.wipo.int/pct/en/forms/).“
