6.12 Copy of the search results for the priority or priorities 

An applicant claiming priority within the meaning of Art. 87 must file a copy of the results of any search carried out by the authority with which the previous application was filed together with the European patent application either without delay after receiving such results or, in the case of a Euro-PCT application, on entry into the European phase. This requirement also applies to priority claims that are subsequently withdrawn or lapse and to priority claims introduced or corrected after the filing date (see A‑III, 6.5.1 and A‑III, 6.5.2). The obligation under Rule 141(1) exists as long as the application is pending before the EPO and applies to all European and Euro-PCT applications filed on or after 1 January 2011 (OJ EPO 2009, 585). In the case of divisional applications, the relevant date is that on which the divisional application was received by the EPO (see A‑IV, 1.2.1), not the filing date of the parent application. Where the copy is not provided to the EPO before the examining division assumes responsibility, the procedure is as set out in C‑II, 5 and C‑III, 6.

Where multiple priorities are claimed, the copy of the search results referred to above must be provided for all applications claimed as priority. If the search results are not drawn up in an official EPO language, no translation is required. The copy of the search results submitted must be a copy of the official document issued by the office where the previous application was filed. A simple listing of the prior art drawn up by the applicant will not suffice. Copies of the cited documents do not have to be provided (see the notice from the EPO dated 28 July 2010, OJ EPO 2010, 410).

The copy referred to in Rule 141(1) is deemed duly filed if it is available to the EPO and is to be included in the European patent application's file under the conditions determined by the EPO President. According to the decision of the President of the EPO dated 5 October 2010, OJ EPO 2010, 600, these exceptions relate to cases where a search report of the following type was drawn up by the EPO on an application whose priority is claimed:

(i)European search report (Art. 92)

(ii)international search report (Art. 15(1) PCT)

(iii)international-type search report (Art. 15(5) PCT)

(iv)search report prepared on behalf of a national office on a national application. As at October 2021, the EPO performs searches for the national offices of Albania, Belgium, Croatia, Cyprus, France, Greece, Italy, Latvia, Lithuania, Luxembourg, Malta, Monaco, Netherlands, San Marino, United Kingdom. 

The EPO also includes a copy of the search results referred to in Rule 141(1) in the European patent application's file, thus exempting the applicant from filing said copy where, based on an agreement with the national patent offices, the priority of a first filing made in one of the following states is claimed:

– Austria (see the decision of the President of the EPO dated 19 September 2012, OJ EPO 2012, 540)

– People's Republic of China (see the decision of the President of the EPO dated 8 April 2021, OJ EPO 2021, A38)

– Czech Republic (see the decision of the President of the EPO dated 11 July 2022, OJ EPO 2022, A79)

– Denmark (see the decision of the President of the EPO dated 10 December 2014, OJ EPO 2015, A2)

– Japan (see the decision of the President of the EPO dated 9 December 2010, OJ EPO 2011, 62)

– Republic of Korea (see the decision of the President of the EPO dated 27 February 2013, OJ EPO 2013, 216)

– Spain (see the decision of the President of the EPO dated 10 February 2016, OJ EPO 2016, A18)

– Sweden (see the decision of the President of the EPO dated 14 May 2021, OJ EPO 2021, A39)

– Switzerland (see the decision of the President of the EPO dated 4 June 2019, OJ EPO 2019, A55)

– United Kingdom (see the decision of the President of the EPO dated 9 December 2010, OJ EPO 2011, 62)

– United States of America (see the decision of the President of the EPO dated 9 December 2010, OJ EPO 2011, 62)

For divisional applications, where the results of the search on the claimed priority have already been provided in respect of the parent application, the applicant need not provide them again in respect of the divisional application (see the notice from the EPO dated 28 July 2010, OJ EPO 2010, 410).
