 2428 Sample Statements under WIPO ST.25 [R-07.2022]

 [Editor Note: This section is not applicable to applications filed on or after
 July 1, 2022, having disclosures of nucleotide and/or amino acid sequences as defined in
 37 CFR
 1.831(b) . See MPEP §§
 2412 - 2419 for guidance on WIPO ST.26
 requirements for applications filed on or after July 1, 2022.] 

 Sample language for the statements required to support sequence rule
 submissions is provided below. These statements are given by way of example only and are
 not exhaustive; other language may, of course, be used. For the statements that relate to
 the assertion that the sequence information contained in the PDF image file or the physical
 sheets of paper and the computer readable form are “identical” or “the same,” it is
 acknowledged that there may be some non-substantive differences between the two, e.g., page
 numbers and page breaks may be present in the PDF image file or the physical sheets of
 paper but not in the computer readable form thereof. This requirement for sameness relates
 to the informational content of the PDF image file or the physical sheets of paper and the
 CRF relevant to the requirements of the sequence rules. 
 

 
 37
 CFR 1.821(e)(1)(ii) , (2)(ii) , 1.825(a)(6) , or (b)(7) - I hereby state that the sequence information
 contained in the computer readable form is identical to the sequence information
 contained in the “Sequence Listing” submitted as a PDF image file or on physical
 sheets of paper. 

 

 37 CFR 1.825(a)(3) and
 (4) - I hereby state that the amendment adding a “Sequence
 Listing”, made in accordance with 37 CFR 1.825(a) is supported in
 the application, as originally filed, at [insert the basis for all sequence data in
 the “Sequence Listing” with specific references to particular parts of the
 application (specification, claims, drawings) as originally filed]. I hereby state
 that the “Sequence Listing” does not include new matter. 

 

 37 CFR
 1.825(b)(3) , (4) , and (5) 
 - - I hereby state that the previous “Sequence Listing” that is replaced by the
 currently submitted replacement “Sequence Listing” in accordance with
 37 CFR
 1.825(b) is amended by [identify the location of all deletions,
 replacements, or additions to the previous “Sequence Listing”]. I hereby state that
 the replacement “Sequence Listing”, made in accordance with 37 CFR 1.825(b) 
 is supported in the application, as originally filed, at [insert the basis for all
 sequence data in the “Sequence Listing” with specific references to particular parts
 of the application (specification, claims, drawings) as originally filed]. I hereby
 state that the replacement “Sequence Listing”, submitted in accordance with
 37 CFR
 1.825(b) , includes no new matter.
