MPEP § 1414
The reissue oath/declaration is an essential part of a reissue application and must be filed with the application, or within the time period set under 37 CFR 1.53(f) along with the required surcharge as set forth in 37 CFR 1.16(f) in order to avoid abandonment.
The question of the sufficiency of the reissue oath/declaration filed under 37 CFR 1.175 must in each case be reviewed and decided personally by the primary examiner.
Reissue oaths or declarations must contain the following:
These elements will now be discussed:
In order to satisfy this requirement, a declaration can state as for example:
It should be noted that the reissue oath/declaration must also satisfy the requirement for a statement of at least one error being relied upon as the basis for reissue, in the manner set forth in subsection II. below.
Even though only one error upon which reissue is based needs to be described in the reissue oath/declaration, if PTO/SB/51 or PTO/SB/52 form is used, applicant needs to check the appropriate box(es) on the form identifying each of the reasons why the patent is wholly or partly inoperative or invalid. Even if a PTO form is not used, applicant needs to state all the reasons why the patent is wholly or partly inoperative or invalid in the reissue oath/declaration.
Form paragraph 14.01 may be used where the reissue oath/declaration does not provide the required statement as to applicant’s belief that the original patent is wholly or partly inoperative or invalid.
The reissue oath/declaration filed with this application is defective because it fails to contain the statement(s) required under 37 CFR 1.175(a)(1) as to applicant’s belief that the original patent is wholly or partly inoperative or invalid. See 37 CFR 1.175(a)(1) and see MPEP § 1414. [1]
1. Use this form paragraph when applicant: (a) fails to allege that the original patent is inoperative or invalid and/or (b) fails to state the reason of a defective specification or drawing, or of patentee claiming more or less than patentee had the right to claim in the patent. In bracket 1, point out the specific defect to applicant by using the language of (a) and/or (b), as it is appropriate.
2. Form paragraph 14.14 must follow this form paragraph.
Where more than one error is specified in the oath/declaration and some of the designated "errors" are found to not be "errors" under 35 U.S.C. 251, any remaining error which is an error under 35 U.S.C. 251 will still support the reissue.
The "at least one error" which is relied upon to support the reissue application must be set forth in the oath/declaration. It is not necessary, however, to point out how (or when) the error arose or occurred. Further, it is not necessary to point out how (or when) the error was discovered. If an applicant chooses to point out these matters, the statements directed to these matters will not be reviewed by the examiner, and the applicant should be so informed in the next Office action. All that is needed for the oath/declaration statement as to error is the identification of "at least one error" relied upon.
In identifying the error, it is sufficient that the reissue oath/declaration identify a single word, phrase, or expression in the specification or in an original claim, and how it renders the original patent wholly or partly inoperative or invalid. The corresponding corrective action which has been taken to correct the original patent need not be identified in the oath/declaration. If the initial reissue oath/declaration "states at least one error" in the original patent, and, in addition, recites the specific corrective action taken in the reissue application, the oath/declaration would be considered acceptable, even though the corrective action statement is not required.
A statement in the oath/declaration of "…failure to include a claim directed to…" and then reciting all the limitations of a newly added claim, would not be considered a sufficient "error" statement because applicant has not pointed out what the other claims lacked that the newly added claim has, or vice versa. Such a statement would be no better than saying in the reissue oath or declaration that "this application is being filed to correct errors in the patent which may be noted from the change made by adding new claim 10." In both cases, the error has not been identified.
Likewise, a statement of the error as "…the inclusion of claims 3-5 which were unduly broad…" and then canceling claims 3-5, would not be considered a sufficient "error" statement because applicant has not pointed out what the canceled claims lacked that the remaining claims contain. The statement of what the remaining claims contain need not identify specific limitations, but rather may provide a general identification, such as "Claims 3-5 did not provide for any of the tracking mechanisms of claims 6-12, nor did they provide an attachment mechanism such as those in claims 1-2 and 9-16."
Where a continuation reissue application is filed with a copy of the reissue oath/declaration from the parent reissue application, and the parent reissue application is, or will be abandoned, the copy of the reissue oath/declaration should be accepted by the Office of Patent Application Processing (OPAP), and the examiner should check to ensure that the oath/declaration identifies an error which is still being corrected in the continuation application. If a preliminary amendment was filed with the continuation reissue application, the examiner should check for the need of a supplemental reissue oath/declaration. Pursuant to 37 CFR 1.175 (b)(1), for any error corrected via the preliminary amendment which is not covered by the oath or declaration submitted in the parent reissue application, applicant must submit a supplemental oath/declaration stating that such error arose without any deceptive intention on the part of the applicant. See MPEP § 1414.01.
Where a divisional reissue application is filed with a copy of the reissue oath/declaration from the parent reissue application, the reissue oath/declaration should be accepted by OPAP, because it is an oath/declaration, though it may be improper under 35 U.S.C. 251 . The examiner should check the copy of the oath/declaration to ensure that it identifies an error being corrected by the divisional reissue application. The copy of the oath/declaration from the parent reissue application may or may not cover an error being corrected by the divisional reissue application because the divisional reissue application is (by definition) directed to a new invention. If it does not, the examiner should reject the claims of the divisional reissue application under 35 U.S.C. 251 as being based on an oath/declaration that does not identify an error being corrected by the divisional reissue application, and require a new oath/declaration. If the copy of the reissue oath/declaration from the parent reissue application does in fact cover an error being corrected in the divisional reissue application, no such rejection should be made. However, because a new invention is being added by the filing of the divisional reissue application, a supplemental reissue oath/declaration pursuant to 37 CFR 1.175 (b)(1) will be required. See MPEP § 1414.01.
Form paragraph 14.01.01 may be used where the reissue oath/declaration does not identify an error.
The reissue oath/declaration filed with this application is defective because it fails to identify at least one error which is relied upon to support the reissue application. See 37 CFR 1.175(a) (1) and MPEP § 1414.
1. Use this form paragraph when the reissue oath or declaration does not contain any statement of an error which is relied upon to support the reissue application.
2. This form paragraph can be used where the reissue oath or declaration does not even mention error. It can also can be used where the reissue oath or declaration contains some discussion of the concept of error but never in fact identifies a specific error to be relied upon. For example, it is not sufficient for an oath or declaration to merely state "this application is being filed to correct errors in the patent which may be noted from the changes made in the disclosure."
3. Form paragraph 14.14 must follow this form paragraph.
Where the reissue oath/declaration does identify an error or errors, the oath/declaration must be checked carefully to ensure that at least one of the errors identified is indeed an "error" which will support the filing of a reissue, i.e., an "error" that will provide grounds for reissue of the patent. See MPEP § 1402. If the error identified in the oath/declaration is not an appropriate error upon which a reissue can be based, then the oath/declaration must be indicated to be defective in the examiner’s Office action.
Form paragraphs 14.01.02 and 14.01.03 may be used where the reissue oath/declaration fails to provide at least one error upon which a reissue can be based.
The reissue oath/declaration filed with this application is defective because the error which is relied upon to support the reissue application is not an error upon which a reissue can be based. See 37 CFR 1.175(a) (1) and MPEP § 1414.
1. Use this form paragraph when the reissue oath/declaration identifies only one error which is relied upon to support the reissue application, and that one error is not an appropriate error upon which a reissue can be based.
2. Form paragraph 14.14 must follow this form paragraph.
The reissue oath/declaration filed with this application is defective because none of the errors which are relied upon to support the reissue application are errors upon which a reissue can be based. See 37 CFR 1.175(a) (1) and MPEP § 1414.
1. Use this form paragraph when the reissue oath/declaration identifies more than one error relied upon to support the reissue application, and none of the errors are appropriate errors upon which a reissue can be based.
2. Note that if the reissue oath/declaration identifies more than one error relied upon, and at least one of the errors is an error upon which reissue can be based, this form paragraph should not be used, despite the additional reliance by applicant on "errors" which do not support the reissue. Only one appropriate error is needed to support a reissue.
3. Form paragraph 14.14 must follow this form paragraph.
In order to satisfy this requirement, the following statement may be included in an oath or declaration:
"All errors corrected in the present reissue application up to the time of signing of this oath/declaration, or errors which are being corrected by a paper filed concurrently with this oath/declaration which correction of errors I/we have reviewed, arose without any deceptive intention on the part of the applicant."
Nothing more is required. The examiner will determine only whether the reissue oath/declaration contains the required averment; the examiner will not make any comment as to whether it appears that there was in fact deceptive intention (see MPEP § 2022.05). It is noted that a reissue oath/declaration will not be effective for any errors which are corrected by a filing made after the execution of the reissue oath/declaration, unless it is clear from the record that the parties executing the document were aware of the nature of the correction when they executed the document. Further, a reissue oath/declaration with an early date of execution cannot be filed after a correction made later in time, to cover the correction made after the execution date. This is so, even if the reissue oath/declaration states that all errors up to the filing of the oath/declaration arose without any deceptive intention on the part of the applicant.
Form paragraph 14.01.04 may be used where the reissue oath/declaration does not provide the required statement as to "without any deceptive intention on the part of the applicant."
The reissue oath/declaration filed with this application is defective because it fails to contain a statement that all errors which are being corrected in the reissue application up to the time of filing of the oath/declaration arose without any deceptive intention on the part of the applicant. See 37 CFR 1.175 and MPEP § 1414.
1. Use this form paragraph when the reissue oath/declaration does not contain the statement required by 37 CFR 1.175 that all errors being corrected in the reissue application arose without any deceptive intention on the part of the applicant.
2. This form paragraph is appropriate to use for a failure by applicant to comply with the requirement, as to any of 37 CFR 1.175(a) (2), 37 CFR 1.175(b) (1), or 37 CFR 1.175(b) (2).
3. Form paragraph 14.14 must follow.
The reissue oath/declaration must include the averments required by 37 CFR 1.63(a) and (b), e.g., that applicants for reissue
The examiner should check carefully to ensure that all the requirements of 37 CFR 1.63 are met. Form paragraph 14.01.05 should be used in conjunction with the content of form paragraphs 6.05 through 6.05.20 as appropriate, where the reissue oath/declaration fails to comply with the requirements of 37 CFR 1.63.
The reissue oath/declaration filed with this application is defective (see 37 CFR 1.175 and MPEP § 1414) because of the following:
1. Use this form paragraph when the reissue oath/declaration does not comply with 37 CFR 1.175, and none of form paragraphs 14.01 - 14.01.04 or 14.05.02 apply.
2. This form paragraph must be followed by an explanation of why the reissue oath/declaration is defective.
3. Form paragraph 14.14 must follow the explanation of the defect.
Claim [1] rejected as being based upon a defective reissue [2] under 35 U.S.C. 251 as set forth above. See 37 CFR 1.175.
The nature of the defect(s) in the [3] is set forth in the discussion above in this Office action.
1. In bracket 1, list all claims in the reissue application. See MPEP § 706.03(x).
2. This paragraph should be preceded by at least one of the paragraphs 14.01 to 14.01.04.
3. In brackets 2 and 3, insert either --oath-- or --declaration--.
See MPEP § 1414.01 for a discussion of the requirements for a supplemental reissue oath/declaration.
Depending on the circumstances, either form PTO/SB/51, Reissue Application Declaration By The Inventor, or form PTO/SB/52, Reissue Application Declaration By The Assignee may be used to prepare a declaration in a reissue application.






If additional defects or errors are corrected in the reissue after the filing of the application and the original reissue oath or declaration, a supplemental reissue oath/declaration must be filed, unless all additional errors corrected are spelling, grammar, typographical, editorial or clerical errors which are not errors under 35 U.S.C. 251 (see MPEP § 1402). In other words, a supplemental oath/declaration is required where any "error" under 35 U.S.C. 251 has been corrected and the error was not identified in the original reissue oath/declaration.
The supplemental reissue oath/declaration must state that every error which was corrected in the reissue application not covered by the prior oath(s)/declaration(s) submitted in the application arose without any deceptive intention on the part of the applicant.
An example of acceptable language is as follows:
"Every error in the patent which was corrected in the present reissue application, and is not covered by the prior declaration submitted in this application, arose without any deceptive intention on the part of the applicant."
A supplemental reissue oath/declaration will not be effective for any errors which are corrected by a filing made after the execution of the supplemental reissue oath/declaration, unless it is clear from the record that the parties executing the document were aware of the nature of the correction when they executed the document. Further, a supplemental reissue oath/declaration with an early date of execution cannot be filed after a correction made later in time, to cover the correction made after the execution date. This is so, even if the supplemental reissue oath/declaration states that all errors up to the filing of the supplemental reissue oath/declaration oath or declaration arose without any deceptive intention on the part of the applicant.
Form PTO/SB/51S, "Supplemental Declaration For Reissue Patent Application To Correct ‘Errors’ Statement (37 CFR 1.175 )," may be used to prepare a supplemental reissue declaration. Form PTO/SB/51S serves to indicate that every error in the patent that was corrected in the reissue application, but was not covered by a prior reissue oath/declaration submitted in the reissue application, arose without any deceptive intention on the part of the applicant.
In the event that the applicant for a reissue applicant is required to file a supplemental reissue oath/declaration that also includes a specific statement of the error being corrected by reissue in accordance with 37 CFR 1.175 (c), as discussed in subsection I. below, applicant must also include in the supplemental declaration language equivalent to the "Every error …" language in the example of acceptable language set forth above. Therefore, if either form PTO/SB/51, "Reissue Application Declaration By The Inventor," or form PTO/SB/52, "Declaration By The Assignee" (see MPEP § 1414) is used for the purpose of filing such supplemental reissue oath/declaration, the form must be completed so that it is clear that the supplemental reissue oath/declaration addresses all errors corrected subsequent to the date upon which the last previously reissue oath/declaration (whether original or supplemental) was filed. For example, the form could be completed by specifying the date upon which the reissue application was originally filed, the reissue application number, and the date(s) of every amendment filed subsequent to the date upon which the last reissue oath/declaration (whether original or supplemental) was filed. Any manner of completing the form so that affiant/declarant unambiguously states that every error corrected subsequent to the filing of the last filed reissue oath/declaration (whether original or supplemental) arose without deceptive intent will be acceptable. It will not be acceptable for the new ("catch-up") oath/declaration to simply refer to the reissue application as filed, even though the new oath/declaration may be submitted after an amendment.
In the supplemental reissue oath/declaration, there is no need to state an error which is relied upon to support the reissue application if:
If applicant chooses to state any further error at this point (even though such is not needed), the examiner should not review the statement of the further error.
The supplemental reissue oath/declaration must state an error which is relied upon to support the reissue application only where one of the following is true:
The supplemental oath/declaration in accordance with 37 CFR 1.175(b) (1) must be submitted before allowance. See MPEP § 1444 for a discussion of the action to be taken by the examiner to obtain the supplemental oath/declaration in accordance with 37 CFR 1.175(b) (1), where such is needed.
Where applicant seeks to correct an error after allowance of the reissue application, a supplemental reissue oath/declaration must accompany the requested correction stating that the error(s) to be corrected arose without any deceptive intention on the part of the applicant. The supplemental reissue oath/declaration submitted after allowance will be directed to the error applicant seeks to correct after allowance. This supplemental oath/declaration need not cover any earlier errors, because all earlier errors should have been covered by a reissue oath/declaration submitted before allowance.
A broadening reissue application must be applied for by all of the inventors (patentees), that is, the original reissue oath/declaration must be signed by all of the inventors. See MPEP § 1414. If a supplemental oath/declaration in a broadening reissue application is subsequently needed in the application in order to fulfill the requirements of 37 CFR 1.175, the supplemental reissue oath/declaration must be signed by all of the inventors. In re Hayes, 53 USPQ2d 1222, 1224 (Comm’r Pat. 1999) ("37 CFR 1.175(b)(1), taken in conjunction with Section 1.172, requires a supplemental declaration be signed by all of the inventors. This is because all oaths or declarations necessary to fulfill the rule requirements in a reissue application are taken together collectively as a single oath or declaration. Thus, each oath and declaration must bear the appropriate signatures of all the inventors.").
If a joint inventor refuses or cannot be found or reached to sign a supplemental oath/declaration, a supplemental oath/declaration listing all the inventors, and signed by all the available inventors may be filed provided it is accompanied by a petition under 37 CFR 1.183 along with the petition fee, requesting waiver of the signature requirement of the nonsigning inventor.
