Applicants may request the withdrawal of their international application on condition that the international publication can be prevented ("conditional withdrawal"). In such a case, the withdrawal does not become effective if the condition cannot be met, that is, if the IB has already completed the technical preparations for the international publication. It is recommended that conditional withdrawals be submitted direct to the IB, especially if the date of completion of the technical preparations is imminent.[]
