The international publication can be prevented provided notice of withdrawal reaches the International Bureau before technical preparations for publication are completed (Art 21(5) PCT and R 90bis.1(c) PCT).

The technical preparations are generally completed by the 15th day prior to the date of publication (PCT applicant’s GUIDE VOL I, [9.014]) i.e prior to the expiry of the 18 month period (Art21(2)(a)PCT).

Therefore, a withdrawal of the application before that day will ensure that the application will not be published.
