Guide for applicants, Part 2: PCT procedure before the EPO (Euro-PCT Guide)

International publication of the application and the ISR
The international publication of the international application by the IB takes place promptly after expiry of 18 months from the priority date. If the ISR is available at that time it will be published together with the application. If not, the ISR is published separately from the international application on receipt by the IB. 
Unlike the ISR, the WO-ISA will not be published. However, aA WO-ISA established for an international application filed on or after 1 July 2014 will be made available to the public as of the date of publication of the international application.

Access to the WO-ISA
Without prejudice to the change entering into effect on 1 July 2014 (see point 236), the IB and the ISA will not, unless authorised by the applicant, allow anyone access to the WO-ISA before the expiry of 30 months from the priority date. After that date the EPO as designated Office will grant access to the WO-ISA. If the application is the subject of international preliminary examination by the EPO as IPEA, the WO-ISA established by the EPO as ISA will be considered a first written opinion for the purposes of the procedure under Chapter II PCT and may as such become public as part of the Chapter II PCT file even before expiry of the 30-month time limit (see point 409).
