Supplemental sheet A is prepared by the search division before publication of the application, regardless of whether this is with the search report (A1 publication) or without it (A2 publication). The information contained in supplemental sheet A is needed for the publication of the application.
On supplemental sheet A, the search division indicates:
If the search report is published separately (A3 publication), information about the abstract is not given in the communication. The information sent to the applicant includes the title of the invention and the figure, if any, of the drawings to be published with the abstract.
In exceptional cases, the search division may change the abstract after the search has been carried out. However, if this is done after the application has been published A2, supplemental sheet A is not reissued;
The European Patent Bulletin is published in all three official languages of the EPO according to Art. 14(7)(a) and contains the entries made in the Register of European Patents, which, according to Rule 143(1)(c), must contain the title of the invention. Consequently, the title is required in all three official languages of the EPC.
The above applies equally to applications published with the search report (A1 publication) and those published without it (A2 publication). In the case of an A2 publication, supplemental sheet A further contains the IPC classification of the application (see B‑X, 5). In the case of an A1 publication, the IPC classification appears only on the search report (Rule 61(6)).
Supplemental sheet A also indicates the nature of the publication to which it relates (A1 or A2).
In the case of a supplementary European search report in respect of an international application, supplemental sheet A is marked A4. The search division does not determine the title, abstract or figure to be published with the abstract, since these have already been determined by the International Searching Authority according to Rules 37.2 PCT, Rules 38.2(a) PCT and Rules 8.2 PCT, respectively.
