Where the Euro-PCT application discloses nucleotide or amino acid sequences, a sequence listing in electronic form drawn up in compliance with the applicable WIPO standard
must be available to the EPO as a designated/elected Office on expiry of the 31-month time limit. For international applications filed up until 30 June 2022, WIPO Standard ST.25 is applicable; for international applications filed on or after 1 July 2022, WIPO Standard ST.26 is applicable. Extensive information about sequence listing Standard ST.25 is provided in the notice from the EPO dated 18 October 2013. Details of the practice which will be applied for applications filed on or after 1 July 2022 are provided in the decision of the President of the EPO dated 9 December 2021 on the filing of sequence listings and the explanatory notice from the EPO (see OJ 2021, A96
and OJ 2021, A97
). The sequence listing must be filed in electronic format only; consequently, a sequence listing filed on paper or in PDF format will be disregarded. The following paragraphs describe the practice applicable for international applications filed up until 30 June 2022.
