4.2.5.1 Nucleotide and amino acid sequences
4.2.010If your European patent application discloses nucleotide or amino acid sequences, the description must include a sequence listing in XML format complying with WIPO Standard ST.26. You are advised to use WIPO's free "WIPO Sequence" software for preparing a Standard ST.26 sequence listing. The sequence listing must not be filed on paper or in PDF or TXT format.
Electronic sequence listings are usually filed online, using the EPO's Online Filing or Online Filing 2.0. Uploading to EPO Form 1001 is enabled if you indicate that the application includes a sequence listing by ticking the relevant check box ("Biology/Application details" tab). The EPO Contingency Upload Service allows you to attach a sequence listing in XML format. Further advice is obtainable from the EPO by contacting User Services at epo.org/contact.
4.2.011The standardised presentation of such nucleotide and amino acid sequences in electronic form is mandatory. If you do not comply with the requirements even following an invitation to do so, including payment of the late furnishing fee, your European patent application will be refused (but see point 5.10.007).
