2.29.9 Requirements for Amino Acid and Nucleotide Sequences on Compact Disc or Other Electronic Means

Date Published

Applicants may file an amino acid or nucleotide sequence on a compact disc (CD) or other electronic means. The supplied sequences must be in a format approved by the Commissioner, i.e. the sequences must comply with the standard provided for in Annex C of the Administrative Instructions under the PCT.  The software known as PatentIn conforms to the format specified in the Annex and is available at:


For national applications, examiners should note that a computer readable form of a sequence listing on CD is instead of any written sequence listing in the application, rather than in addition to the sequence listing as required for applications filed under the PCT. (Paragraphs 39 and 40 of Annex C of the Administrative Instructions do not apply.) The sequence listing and identifying data can be provided to the Office on CD as a general text file generated by PatentIn, or as a text file identical to that generated by PatentIn.

Note: The provision of sequences in electronic form is optional. Applicants may therefore choose to supply such sequences in printed form. Examiners cannot request that applicants supply sequences in electronic form.

Note: The relevant provisions are:

>•  Formalities Determination (sec 16)
•  Schedule 3 (clause 12).

See 2.29 Formalities and Forms for further information.

CD Requirements

The entire printable copy of the sequence listing and identifying data should be contained within one text file on a single standard (ISO9660) CD-ROM or CD-R in an uncompressed format. If the text file is too large for a single CD, then multiple CDs may be filed. Each CD should contain one text file only.

CDs will be subject to a formality check at the time of filing by COG. This will check for viruses, determine if there is a text file on the disc and whether it can be opened. However, it should be noted that the content of the CD will not be checked in any way and the onus is on the applicant to ensure that all the desired sequences are actually on the CD. Where a CD is supplied, but does not comply with the requirements, e.g. the information is unreadable or the CD has a virus associated with it, the applicant will be issued with a formalities notice and asked to supply a substitute CD.

Any amendment to the CD must be made by submitting a substitute CD. Any correction or amendment of the CD is subject to the normal provisions of the Act, including that the amendment must be allowable under sec 102.

Note: The CD must be submitted as part of the application. If a CD is submitted later, it must be accompanied by a request under sec 104 and will be subject to the normal provisions for amendments.
