This revised version of the Guidelines for Examination will apply as from 1 November 2015. Until then, the September 2014 edition of the Guidelines remains valid.

3.5 Abandonment of priority claim

An applicant may voluntarily abandon a claimed priority at any time. If he does so before the technical preparations for publication have been completed, then the priority date is not effective and the publication is deferred until 18 months after the filing date. If it is abandoned after the technical preparations for publication have been completed, then the application is still published 18 months after the priority date originally claimed (see A‑VI, 1.1 and G‑IV, 5.1.1).
