The international application must contain an abstract and a title (see also GL/PCT‑EPO F‑II, 2 and 3). If the search report is published together with the application (A1 publication), the examiner indicates on supplemental sheet A:[Rule 44.2; GL/ISPE 16.33; ]
If the application is to be published before the international search report is prepared (A2 publication, see GL/EPO B‑X, 4), the examiner only needs to prepare the classification data. Titles, abstracts and figures are published as submitted by the applicant.[GL/ISPE 15.40; ]
It is to be noted that first filings (i.e. applications not claiming priority from an earlier application) cannot be published as A2.
