Subsection 17.05.07c – entire subsection

Previous text Revised text
Previous section 17.05.07c has been moved to new section 17.05.07f

Each nucleotide or amino acid sequence disclosed in an application, other than a sequence identified as forming a part of the prior art, is assigned a separate sequence identifier in the sequence listing. The sequence identifier is a unique integer that appears beside numeric identifiers <210> and <400> in the sequence listing for each sequence. The sequence identifiers begin with 1 and increase in sequential order.

In cases where no nucleotide or amino acid sequence is present for a given sequence identifier, the code 000 should appear beneath numeric identifier <400>, beginning on the next line following the sequence identifier.

Except in situations where the entire sequence listing is removed from the application, the original sequence identifier assigned to a given sequence should be maintained even after amendment of the application. Thus, in cases where a nucleotide or amino acid sequence is removed from the sequence listing by amendment, the nucleotide or amino acid sequence originally presented beneath numeric identifier <400> should be replaced with code 000. In such cases, only data for numeric identifiers <210> and <400> are required. It is noted that the removal of the subject-matter from the description must not cause the application to become non-compliant with subsection 27(3) (see 17.05.07) or subsection 38.2(2) of the Patent Act (see Chapter 19 of this manual for further guidance on amendments to patent applications).

Numeric identifier <160>, which precedes the presentation of the actual nucleotide and/or amino acid sequences of the application, represents the total number of sequence identifiers in the sequence listing including those having code 000 at <400>.
Please consult the PCT sequence listing standard available via the WIPO website for more information about numeric identifiers and the presentation of sequences.

Example:

The originally-filed sequence listing featured three DNA sequences. The sequence listing below has been correctly amended to remove the DNA sequence originally identified as SEQ ID NO:2 in the application.

Identification of a sequence listing

In accordance with subsection 86(3) of the Patent Rules, the claims may refer to sequences represented by sequence listings by the sequence identifier and preceded by "SEQ ID NO:". The sequence identifier can simply be an Arabic numeral, such that the first sequence identified in the description could be identified as SEQ ID NO:1, the second as SEQ ID NO:2, etc.

Correction of a sequence listing

If a sequence listing is found to contain errors, any correction of the listing must comply with the requirements of subsection 38.2(2) of the Patent Act. That is, no new matter may be added to the specification or drawings as originally filed and any correction made to a sequence listing must be reasonably inferable from the specification or drawings as filed. Where the corrected sequence could only be determined by, for example, re-sequencing a sample, the correction is not reasonably to be inferred.

A reissue application is not a means for reopening the prosecution and permitting a patentee to amend a patent as they would amend a patent application during its normal prosecution. Nor does it permit a patentee to unilaterally narrow the scope of protection as would filing a disclaimer—a reissue application must satisfy the requirements of subsection 47(1) of the Patent Act.

23.03.07 Examination of an application for reissue
April 2017

Unlike disclaimers, an application for reissue can result in the widening of a patent's scope; the scope of protection can be increased, thereby affecting the bargain with the public. The Patent Office must therefore examine and approve any application for reissue.51

Given the retroactive effect of reissued patents (subsection 47(2) of the Patent Act), it is important to ensure that an application for reissue meets the requirements of section 47 of the Patent Act. The Reissue Board, consisting of senior patent examiners from the various examination disciplines, oversees the complete reissue application process and is tasked with ensuring that applications for reissue meet those requirements.

For any submitted application for reissue the Reissue Board first verifies that the application for reissue complies with the requirements of section 47 of the Patent Act as detailed in sections 23.03.02-23.03.05 of this manual.  This verification will involve a review of the application, proposed amendments and submitted evidence as well as the record of prosecution in the Patent Office and, if applicable, foreign patent offices.  If the application complies with the requirements then an examiner of the relevant art verifies that the reissued patent would comply with the rest of the Patent Act and Rules.  This verification is analogous to the examination of a patent application and may identify any defect that would be applicable during said examination.

If the Reissue Board or examiner finds the reissue application to be noncompliant with the Patent Act and Rules, an office letter explaining why will be issued.  The patentee may respond by arguing and clarifying points, providing further evidence (which will be put on file), and/or by amending the proposed description, drawings and/or claims.  The response should address the issues identified in the office letter.

However, sections 3 to 5 of Form 1 may not be amended other than to correct obvious typographical errors; section 47 of the Patent Act does not permit amendments to Form 1 that change the reasons for reissue.

If an impasse is reached between the patentee and the Reissue Board or the examiner, the reissue application may be referred to the Patent Appeal Board, who will make a recommendation to the Commissioner of Patents.

A patentee should present the best evidence upon filing Form 1.  All issues and evidence should be before the Reissue Board and examiner prior to any referral to the Patent Appeal Board.  Further, before an application is forwarded to the Patent Appeal Board, all deficiencies therein with regards to the Patent Act and Rules must have been identified by the Reissue Board and examiner, even if an impasse occurs in the initial stage of examination before the Reissue Board.

A reissue application does not go abandoned for failing to respond to an office letter within a certain time period, and thus there are no corresponding reinstatement fees. On the other hand, failure to respond in a timely manner can result in the reissue application being forwarded to the Patent Appeal Board and the Commissioner of Patents.

A patentee may always end prosecution by withdrawing the reissue application.

If the application for reissue is found acceptable by both the Reissue Board and the examiner, the patent will be reissued with an "E" document code.  If the original patent was issued on the basis of an application filed after October 1, 1989 then the reissued patent will have the same patent number as the original patent; original patents issued on the basis of applications filed before said date will be reissued with a new patent number in the one million series.  If the application for reissue is found acceptable the Office will send the patentee the new patent.

23.03.08 Multiple applications for reissue
December 2015

A patentee may file separate applications for reissue in respect of distinct parts of the invention covered by the original patent being reissued (subsection 47(3) of the Patent Act). This could result in multiple reissued patents. As with other applications for reissue, each separate application must be filed within four years of the original grant date. The separate reissue applications must all have been filed before the effective date of surrender of the original granted patent, i.e. before the grant of a reissued patent based on any one of them.

This section is permissive in that it allows the patentee to file multiple applications for reissue. The Commissioner of Patents will not call for division of an application for reissue, whether the granted patent appears to have been granted with more than one invention, or an additional invention is being claimed by reissue so that the reissue will contain more than one invention. Under 36(2.1) of the Patent Act, the Commissioner can only call for division of a patent application before the issue of a patent on the original application. Similarly, subsections 36(2), 36(3) and 36(4) of the Patent Act also do not apply to reissue applications.

Each separate application for reissue under subsection 47(3) of the Patent Act must be independently patentable as covering separate inventions in order to ensure that double-patenting does not arise. Where multiple reissue applications co-exist for the same patent, yet do not cover separate and distinct parts of its invention, only one reissued patent (at most) can be granted.

23.03.08a Examination of multiple, co-existing applications for reissue
April 2018

A situation could arise in which one or more co-existing applications for reissue are considered compliant with the Patent Act and Patent Rules, but at least one co-existing application for reissue for the same patent is refused by the Commissioner of Patents or withdrawn by the patentee. If applicable in such a case, the patentee will be notified that they may, if desired and before the expiry of a specified time limit, introduce subject-matter that appears in the refused or withdrawn application for reissue into one of the compliant applications for reissue as long as that subject-matter appeared in the original patent. If, after the introduction of subject-matter, the previously-compliant co-existing application for reissue remains compliant with the Patent Act and Patent Rules, then a patent will proceed to be reissued for the compliant applications for reissue. If the introduction of subject-matter causes the previously-compliant, co-existing application for reissue to fail to comply with the Patent Act and/or Patent Rules, then examination will continue on the previously-compliant, co-existing application for reissue until it is found to be compliant, is refused or is withdrawn.  If no response is received within the specified time limit, then patents will be reissued based on the compliant applications for reissue as they exist on file in the Office.

23.03.10 Effect of a reissued patent
December 2015

The effect of reissue is retroactive and rights exist with respect to the reissued patent as if they had been in effect as of the original grant date (subsection 47(2) of the Patent Act).

A reissued patent may not be withdrawn after it has been issued in favour of the original patent.

Any pending action is not affected by a reissue "to the extent that its claims are identical with the original patent" (subsection 47(2) of the Patent Act). In this context "identical" is taken to mean "of the same scope".

No additional maintenance fees apply to a reissue application (subsections 100(2), 155(2) and 182(2) of the Patent Rules). However, maintenance fees remain payable on the original patent until it reissues (if it reissues), and then become payable on the reissued patent under the same conditions as the original patent (subsections 101(1),(2), 156(1), (2) and 182(3), (4) of the Patent Rules), that is, in accordance with the maintenance fee due dates that apply to the original patent (see chapter 24 of this manual).
