PCT Receiving Office Guidelines

Chapter IX: Nucleotide and/or Amino Acid Sequence Listing

Sheets Not Numbered or Incorrectly Numbered

226.  If sheets containing a sequence listing are not numbered or are incorrectly numbered, the receiving Office may either renumber them ex officio or invite the applicant under Rule 26 to do so by submitting replacement sheets (Rule 26.4 and paragraphs 153 to 159). Where sheets are renumbered, the total number of sheets indicated in the check list may need to be corrected and the receiving Office invites the applicant to pay any required additional fee for sheets in excess of the previously calculated total number of sheets (paragraphs 241 and 252 to 265).
