9.014. When are the technical preparations for international publication completed? The technical preparations for publication are completed by the 15th day prior to the date of publication. However, any change that should be taken into consideration for publication on a specific publication date, should reach the International Bureau at least one day before the 15-day time limit to allow the International Bureau to process the change. The last day for receipt of such changes will therefore always be on Tuesday at midnight (Central European time (CET)), i.e. 16 days before the publication date when publication falls on a Thursday (or 17 days before the publication date when publication exceptionally takes place on a Friday because the International Bureau is closed for business on a Thursday).
