 214 Formal Requirements of Claim for Foreign
 Priority [R-07.2022]
 

 Under the statute ( 35 U.S.C. 119(b) ), an applicant who
 wishes to secure the right of priority must comply with certain formal requirements within
 a time specified. If these requirements are not complied with the right of priority is lost
 and cannot thereafter be asserted.
 

 The maximum time limit specified in the statute is that the
 claim for priority and the priority papers must be filed before the patent is granted, but
 the statute gives the Director authority to set this time limit at an earlier time during
 the pendency of the application. As a result of implementation of Public Law 112-211, 126
 Stat. 1527 (titles I and title II of the Patent Law Treaties Implementation Act (PLTIA)),
 the procedural requirements relating to claims for priority to an earlier-filed foreign
 application and to the submission of a certified copy of the priority document were
 revised. The procedural requirements and the time relating to claims for priority of an
 earlier filed foreign application are set forth in 37 CFR 1.55 . See MPEP §
 214.01 for procedural requirements pertaining to filing a claim
 for priority. See MPEP §§ 215.02 - 215.03 for
 timing requirements for submitting a certified copy of the priority application. See
 MPEP §
 213.06 for claiming foreign priority and filing a certified copy
 of the priority document in a national stage application and MPEP § 213.07 for
 claiming foreign priority and filing a certified copy of the priority document in a
 nonprovisional international design application. 
 

 Where a claim for priority under 35 U.S.C. 119(b) has
 not been made in a parent application, the claim for priority may be made in a continuing
 application provided the parent application has been filed within twelve months from the
 date of the earliest foreign filing (six months for design applications). See In
 re Tangsrud, 184 USPQ 746 (Comm’r Pat. 1973). Where the requirements for
 perfecting priority under 35 U.S.C. 119(a) - (d) or (f) have not been met
 before the issuance of patent, see 37 CFR 1.55(g) and
 MPEP §
 216.01 for an explanation of when the deficiencies are
 correctable by a certificate of correction or reissue. 
 

 It should be particularly noted that the certified copy must
 be filed in all cases even though it may not be necessary during the pendency of the
 application to overcome the date of any reference. The statute also gives the Director
 authority to require a translation of the foreign documents if not in the English language
 and such other information as the Director may deem necessary. See MPEP §
 213.04 for additional information. If an English language
 translation of a non-English language foreign application is required, the translation must
 be that of the certified copy (of the foreign application as filed) and it must be filed
 together with a statement that the translation of the certified copy is accurate.
 

 
 214.01 Time for Filing Priority Claim [R-07.2015]

 
 37 CFR 1.55 Claim for foreign priority. 

 *****

 
 (d) Time for filing priority claim— 
 (1) Application under 35 U.S.C.
 111(a) . The claim for priority must be
 filed within the later of four months from the actual filing date of the
 application or sixteen months from the filing date of the prior foreign
 application in an original application filed under 35 U.S.C.
 111(a) , except as provided in paragraph (e) of this
 section. The claim for priority must be presented in an application data
 sheet (§ 1.76(b)(6) ) and must
 identify the foreign application to which priority is claimed by
 specifying the application number, country (or intellectual property
 authority), day, month, and year of its filing. The time periods in this
 paragraph do not apply if the later-filed application is:
 
 (i) An application for a design
 patent; or
 

 (ii) An application filed under
 35 U.S.C.
 111(a) before November 29, 2000.
 

 
 

 (2) Application under 35 U.S.C.
 371 . The claim for priority must be made
 within the time limit set forth in the PCT and the Regulations under the
 PCT in an international application entering the national stage under
 35
 U.S.C. 371 , except as provided in paragraph (e) of
 this section. 
 

 
 

 
 *****

 

 37 CFR
 1.55(d)(1) sets forth the time periods for filing a priority claim
 in an application filed under 35 U.S.C. 111(a) . See
 37 CFR
 1.55(d)(2) and MPEP §
 213.06 for the time period for claiming priority in an
 application entering the national stage. The time periods set forth in 37 CFR 1.55(d) 
 do not apply to design applications. 
 

 

 For original applications filed under 35 U.S.C.
 111(a) , the requirements of the statute are that the applicant
 must (a) file a claim for the right of priority and (b) identify the original foreign
 application by specifying the application number of the foreign application, the
 intellectual property authority or country in which the application was filed and the
 date of filing of the application. 35 U.S.C. 119(b)(1) specifies that
 the claim for priority and the required identification information must be filed at such
 time during the pendency of the application as set by the Director. For applications
 other than design applications, the Director has by rule set this time period as the
 later of four months from the actual filing date of the application or sixteen months
 from the filing date of the prior foreign application. See 37 CFR
 1.55(d)(1) . This time period is not extendable. In an application
 that entered the national stage from an international application after compliance with
 35 U.S.C.
 371 , the claim for priority must be made during the pendency of
 the application and within the time limit set forth in the PCT and the Regulations under
 the PCT. See 37 CFR 1.55(d)(2) and MPEP §
 213.06 . In a design application, a claim for priority may be
 made at any time during the pendency of the application. See 37 CFR
 1.55(g) . See also MPEP §§ 1504.10 and
 2920.05(d) for additional information pertaining to priority
 claims in design applications. 
 

 Claims for foreign priority not presented within the time
 period specified in 37 CFR 1.55 are considered to have
 been waived. If a claim for priority under 35 U.S.C. 119(a) - (d) or
 (f) , 365(a) or (b) , or
 386(a) or (b) is presented after the time
 period set in 37
 CFR 1.55 , the claim may be accepted if it includes the required
 identification information and is accompanied by a grantable petition to accept the
 unintentionally delayed claim for priority. See MPEP §
 214.02 for the treatment of unintentionally delayed priority
 claims.
 

 For applications filed under 35 U.S.C.
 111(a) on or after September 16, 2012, 37 CFR
 1.55(d)(1) requires the claim for priority to be presented in an
 application data sheet. For applications filed under 35 U.S.C.
 111(a) prior to September 16, 2012, unless provided in an
 application data sheet, the oath or declaration under 37 CFR 1.63 
 must identify the foreign application for patent or inventor’s certificate for which
 priority is claimed under 37 CFR 1.55 , and any foreign
 applications having a filing date before that of the application on which priority is
 claimed, by specifying the application number, country, day, month, and year of its
 filing. See 37 CFR 1.55(n) .
 

 

 
 214.02 Unintentionally Delayed Priority Claims [R-07.2022]

 
 37 CFR 1.55 Claim for foreign priority. 

 *****

 
 (e) Delayed priority claim. Unless such claim is accepted in
 accordance with the provisions of this paragraph, any claim for priority under
 35 U.S.C.
 119(a) through (d) or (f) ,
 365(a) or (b) , or 386(a) or 386(b) not presented in the
 manner required by paragraph (d) or (m) of this section during pendency and
 within the time period provided by paragraph (d) of this section (if
 applicable) is considered to have been waived. If a claim for priority is
 considered to have been waived under this section, the claim may be accepted if
 the priority claim was unintentionally delayed. A petition to accept a delayed
 claim for priority under 35 U.S.C. 119(a) through
 (d) or (f) , 365(a) or
 (b) , or 386(a) or 386(b) must be accompanied by:
 
 (1) The priority claim under
 35
 U.S.C. 119(a) through (d) 
 or (f) , 365(a) or
 (b) , or 386(a) or 386(b) in an application data sheet (§
 1.76(b)(6) ), identifying the foreign application
 to which priority is claimed, by specifying the application number,
 country (or intellectual property authority), day, month, and year of its
 filing, unless previously submitted;
 

 (2) A certified copy of the foreign
 application, unless previously submitted or an exception in paragraph
 (h), (i), or (j) of this section applies;
 

 (3) The petition fee as set forth in §
 1.17(m) ; and
 

 (4) A statement that the entire delay
 between the date the priority claim was due under this section and the
 date the priority claim was filed was unintentional. The Director may
 require additional information where there is a question whether the
 delay was unintentional.
 

 
 

 
 *****

 

 Where a priority claim under 37 CFR
 1.55(g) was not timely made, 37 CFR
 1.55(g) allows the priority claim and the certified copy required
 under 37 CFR
 1.55 to be filed pursuant to a petition under 37 CFR
 1.55(e) even if the application is not pending (e.g., a patented
 application). Thus, a petition under 37 CFR 1.55(e) may be filed along
 with request for a certificate of correction after patent grant. See
 MPEP §
 216.01 . 
 

 If a claim for foreign priority is presented after the
 time period set in 37 CFR 1.55 , the claim may be accepted if it is accompanied by a
 grantable petition to accept the unintentionally delayed claim for priority. In
 addition, a petition to accept an unintentionally delayed claim for foreign priority is
 necessary to correct any error in a foreign priority claim if the correction is sought
 after expiration of the time period set forth in 37 CFR 1.55 . 
 

 In all applications, a grantable petition to accept an
 unintentionally delayed claim for priority must include: (1) the claim (i.e., the claim
 required by 35 U.S.C.
 119(a) - (d) or (f) ,
 365(a) or (b) , or 386(a) 
 or (b) and 37 CFR 1.55 ) for priority to the
 prior foreign application, unless previously submitted; (2) a certified copy of the
 foreign application, unless previously submitted or an exception in 37 CFR
 1.55(h) , (i) , or (j) 
 applies; (3) the petition fee set forth in 37 CFR
 1.17(m) ; and (4) a statement that the entire delay between the
 date the claim was due and the date the claim was filed was unintentional. While the
 Director may require additional information whenever there is a question of whether the
 delay was unintentional, a person filing a petition to accept a delayed priority claim
 more than two years after the date the foreign priority claim was due is required to
 provide additional explanation of the circumstances surrounding the delay that
 establishes that the entire delay was unintentional. This requirement is in addition to
 the requirement to provide a statement that the entire delay was unintentional in
 37 CFR
 1.55(e) . See Clarification of the Practice for Requiring
 Additional Information in Petitions Filed in Patent Applications and Patents Based on
 Unintentional Delay , 85 FR 12222-24 (March 2, 2020). See also
 MPEP §
 711.03(c) for further discussion of the “unintentional” delay
 standard.
 

 37 CFR
 1.55(e)(2) requires that a petition to accept a delayed claim for
 priority be accompanied by a certified copy of the foreign application, unless
 previously submitted or an exception in 37 CFR 1.55(h) , (i) , or
 (j) applies. 37 CFR 1.55(h) contains provisions
 relating to when the requirement for a certified copy will be considered satisfied based
 on a certified copy filed in another U.S. patent or application (see also
 MPEP §
 215 , subsection III); 37 CFR
 1.55(i) contains provisions relating to the priority document
 exchange agreement (see also MPEP §§ 215.01 and
 215.02(a) ); and 37 CFR 1.55(j) contains provisions
 relating to the filing of an interim copy of a foreign application (see also
 MPEP §
 215.02(b) ). If a grantable petition under 37 CFR 1.55(e) is
 filed, a further petition to accept the delayed filing of the certified copy is not
 required.
 

 Priority claims and certified copies of foreign
 applications filed after payment of the issue fee and before the patent grant will be
 placed in the application file but will not be reviewed.
 

 Before May 13, 2015, no procedures were established for
 accepting an unintentionally delayed priority claim in a design application. Effective
 May 13, 2015, 37 CFR 1.55(e) provides for the filing of a petition for
 acceptance of an unintentionally delayed priority claim in a design application where
 the foreign priority claim was not submitted during the pendency of the design
 application. Thus, a petition under 37 CFR 1.55(e) may be filed along
 with request for a certificate of correction after patent grant in utility, plant, and
 design applications. See MPEP § 216.01 . 
 

 

 
 214.03 Office Acknowledgement of Priority Claims [R-07.2022]
 I. UNTIMELY CLAIM FOR PRIORITY If the foreign priority claim in an original application
 filed under 35 U.S.C. 111(a) (other than a design application) is
 submitted after the time period set in 37 CFR 1.55 and without a
 petition under 37 CFR 1.55 , the examiner may use form paragraph
 2.21.01 
 to notify applicant that the foreign priority claim will not be entered.
 

 ¶ 2.21.01 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a) Foreign
 Priority Claim is Untimely
 

 The foreign priority claim filed on [1] was not entered
 because the foreign priority claim was not filed during the time period set forth in
 37 CFR
 1.55 . For original applications filed under 35 U.S.C. 111(a) 
 (other than a design application) on or after November 29, 2000, the time period is during the
 pendency of the application and within the later of four months from the actual filing date of
 the application or sixteen months from the filing date of the prior foreign application. In
 addition, if the application was filed on or after September 16, 2012, the claim for foreign
 priority must be presented in an application data sheet. See 37 CFR 1.55(d)(1) .
 For national stage applications under 35 U.S.C. 371 , the claim for priority must
 be made within the time limit set forth in the PCT and the Regulations under the PCT. See
 37 CFR
 1.55(d)(2) . If applicant desires priority under 35 U.S.C. 119(a)-(d),
 (f) , 365(a) or (b) , or 386(a) based upon a prior foreign
 application, applicant must file a petition for an unintentionally delayed priority claim
 under 37 CFR
 1.55(e) . The petition must be accompanied by (1) the priority claim
 under 35 U.S.C. 119(a)-(d),
 (f) , 365(a) or (b) , or 386(a) in accordance with
 37 CFR
 1.55 identifying the prior foreign application to which priority is
 claimed, unless previously submitted; (2) a certified copy of the foreign application, unless
 previously submitted or an exception under 37 CFR 1.55 applies; (3) the petition fee
 under 37 CFR
 1.17(m) ; and (4) a statement that the entire delay between the date the
 claim was due under 37
 CFR 1.55 and the date the claim was filed was unintentional. The
 Director may require additional information where there is a question whether the delay was
 unintentional. The petition should be addressed to: Mail Stop Petition, Commissioner for
 Patents, P.O. Box 1450, Alexandria, Virginia 22313-1450.
 

 Examiner Note:
 
 1. Use this form paragraph only for original applications filed under
 35 U.S.C.
 111(a) on or after November 29, 2000 and for national stage
 applications under 35
 U.S.C. 371 . DO NOT use for design applications.
 

 2. In bracket 1, insert the date the amendment or paper containing the
 foreign priority claim was filed.
 
 
 
 II. NO IRREGULARITIES AND PRIORITY CLAIM TIMELY When the claim for foreign priority and the certified
 copy of the foreign application are received within the time period set forth in
 37 CFR
 1.55 , if applicable, they are entered into the application file
 history. Assuming that the papers are timely and regular in form and that there are
 no irregularities in dates, the examiner in the next Office action will advise the
 applicant that the papers have been received on form PTOL-326 or by use of form
 paragraph 2.26 . 
 

 ¶ 2.26 Claimed Foreign Priority - Certified Copy Filed

 Receipt is acknowledged of certified copies of papers required by
 37 CFR
 1.55 .
 

 

 Where the foreign priority papers have been filed in a
 parent application, use form paragraph 2.27 .
 

 ¶ 2.27 Acknowledge Certified Copy of Foreign Priority Paper in
 Parent
 

 Acknowledgment is made of applicant’s claim for foreign priority under
 35 U.S.C.
 119(a) - (d) . The certified copy has been filed in parent Application No.
 [1] , filed on [2] .
 

 Examiner Note:
 
 1. For problems with foreign priority, see form paragraphs
 2.18 to
 2.23 .
 

 2. In bracket 1, insert series code
 and serial no. of parent.
 
 
 
 III. FOREIGN APPLICATION FILED MORE THAN A YEAR BEFORE EARLIEST EFFECTIVE U.S.
 FILING Where the earlier foreign application was filed more
 than 12 months prior to the U.S. application and priority has not been restored under
 PCT Rule
 26bis.3 for an international application
 or upon a granted petition under 37 CFR 1.55(c) , use form
 paragraph 2.23 .
 

 ¶ 2.23 Foreign Filing More Than 12 Months Earlier, No Petition to Restore
 Priority Granted
 

 Acknowledgment is made of applicant's claim for priority under
 35 U.S.C.
 119(a)-(d) or (f) , 365(a) or (b) , or 386(a) based
 upon an application filed in [1] on [2] . The claim for priority
 cannot be based on said application, because the subsequent nonprovisional or international
 application designating the United States was filed more than twelve months thereafter and no
 petition under 37 CFR
 1.55 or request under PCT Rule 26bis.3 to
 restore the right of priority has been granted. 
 

 Applicant may wish to file a petition under 37 CFR 1.55(c) to
 restore the right of priority if the subsequent application was filed within two months from
 the expiration of the twelve-month period and the delay was unintentional. A petition to
 restore the right of priority must include: (1) the priority claim under 35 U.S.C. 119(a)-(d) or
 (f) ,
 365(a) or
 (b) , or 386(a) in an application data sheet,
 identifying the foreign application to which priority is claimed, by specifying the
 application number, country (or intellectual property authority), day, month, and year of its
 filing (unless previously submitted); (2) the petition fee set forth in 37 CFR
 1.17(m) ; and (3) a statement that the delay in filing the subsequent
 application within the twelve-month period was unintentional. The petition to restore the
 right of priority must be filed in the subsequent application, or in the earliest
 nonprovisional application claiming benefit under 35 U.S.C. 120 , 121 ,
 365(c) , or 386(c) to the subsequent application, if
 such subsequent application is not a nonprovisional application. The Director may require
 additional information where there is a question whether the delay was unintentional. The
 petition should be addressed to: Mail Stop Petition, Commissioner for Patents, P.O. Box 1450,
 Alexandria, Virginia 22313-1450.
 

 Examiner Note:
 
 1. Use this form paragraph only for original applications
 filed under 35
 U.S.C. 111(a) on or after November 29, 2000 and for national stage
 applications under 35
 U.S.C. 371 . DO NOT use for design applications.
 

 2. In bracket 1, insert the country name.

 3. In bracket 2, insert the
 filing date of the foreign application.
 
 
 
 IV. SOME FOREIGN APPLICATIONS FILED MORE THAN A YEAR BEFORE U.S. FILING For example, where a British provisional specification
 was filed more than a year before a U.S. application, but the British complete
 application was filed within the year, and certified copies of both were submitted,
 language similar to the following should be used: “Receipt is acknowledged of papers
 filed on September 18, 1979, purporting to comply with the requirements of
 35 U.S.C.
 119(a) - (d) . It is not seen how the claim
 for priority can be based on the British specification filed January 23, 1978,
 because the instant application was filed more than one year thereafter. However, the
 printed heading of the patent will note the claimed priority date based on the
 complete specification; i.e., November 1, 1978, for such subject matter as was not
 disclosed in the provisional specification.”
 

 V. APPLICATION IN ISSUE When the claim for foreign priority or the certified
 copy of the foreign application is filed after the date of payment of the issue fee
 but prior to the date of grant of the patent, the foreign priority claim or certified
 copy will be placed in the file record but there may be no review of the papers and
 the patent when published will not include the priority claim. A certificate of
 correction under 35
 U.S.C. 255 and 37 CFR 1.323 can be filed to have
 the foreign priority claim or certified copy considered after publication of the
 patent. In addition, for original applications filed under 35 U.S.C.
 111(a) or international applications entering the national
 stage under 35
 U.S.C. 371 , a grantable petition to accept an unintentionally
 delayed claim for priority under 37 CFR 1.55 and the petition fee
 must be filed with the certificate of correction. See MPEP §
 216.01 .
 

 

 
 214.04 Proper Identification of Priority Application in
 Foreign Priority Claim [R-08.2017]
 

 To ensure an accurate and complete citation of a foreign
 priority application, applicants should review the list of the various intellectual
 property offices and the recommended presentation of a foreign application number for
 each, which can be found in the tables of the online WIPO Handbook on Industrial
 Property Information and Documentation ( www.wipo.int/standards/en/ ),
 Part 7: Examples and Industrial Property Offices Practices ( www.wipo.int/standards/en/part_07.html ), including Part 7.2.1:
 Presentation of Application Numbers ( www.wipo.int/standards/en/pdf/_07-02- 01.pdf ). The tables should
 enable applicants, examiners and others to extract from the various formats the minimum
 required data which comprises a proper citation. The “Minimum Significant Part of the
 Number” identified in the tables should be used in United States Patent and Trademark
 Office records. Proper identification of priority applications is essential to
 establishing accurate and complete relationships among various patent documents,
 especially in the context of electronic priority document exchange programs (see
 MPEP §
 215.01 ).
 

 The tables set forth below include only a partial list of
 recommended presentations of foreign application numbers. A complete updated list of the
 recommended presentation of a foreign application number based on the numbering system
 used by the foreign intellectual property office is maintained by the WIPO and can be
 found in the online WIPO Handbook on Industrial Property Information and Documentation
 as explained above. See also www.wipo.int/export/sites/www/standards/ en/pdf_/07-02-06.pdf for a
 survey of current practices regarding the numbering of applications and priority
 applications.
