2.3 Withdrawal of designations 

An applicant may address a notice of withdrawal of any designations to the IB, the RO or, where a demand has been filed, the IPEA, and may do so at any time prior to the expiration of 30 months from the priority date. Withdrawal of the designation of all designated states is treated as withdrawal of the international application (see GL/PCT‑EPO A‑IV, 2.2). Withdrawal of a designated state which has been elected entails withdrawal of the corresponding election (see GL/PCT‑EPO A‑IV, 2.6). If the withdrawal of a designation reaches the IB prior to completion of the technical preparations for publication, the designation in question is not published.
