Does the receiving Office accept the filing of international applications in electronic form?
Where the international application is filed in electronic form, the total amount of the international filing fee is reduced (refer to “Fees payable to the RO”).
Where the international application contains a sequence listing as a separate part of the description, this should be furnished in accordance with Annex C of the Administrative Instructions, that is, in compliance with WIPO Standard ST.26 XML format; no fees are due for sequence listings filed in this format. Where the international application is filed on paper, a sequence listing part of the description should be furnished in WIPO Standard ST.26 XML format on physical medium.
The USPTO accepts the filing of international applications in electronic form according to its national law and technical systems (refer to Section 703(d) and 703(f)(ii) of the PCT Administrative Instructions). For more information, refer to: https://www.uspto.gov/patents/apply.
Technical support for filing international applications electronically is available from the Patent Electronic Business Center (EBC) at (1-866) 217 91 97. Note that the applicable national law and technical systems provide for requirements which are different from, and not compatible with, the requirements of Section 703(b)(ii) to (iv) of the PCT Administrative Instructions (refer to PCT Gazette No. 18/2002, page 8974). Applicants may, however, use ePCT or PCT-SAFE to generate a .zip file containing a validated request form, and then submit the .zip file electronically via EFS-Web or Patent Center. For further details, refer to: https://www.federalregister.gov/documents/2020/09/30/2020-18743/facilitating-the-use-of-the-world-intellectual-property-organizations-epct-system-to-prepare.

The procedure in the national Phase

US.01 APPLICANT
35 USC 116, 35 USC 117, 35 USC 118, 37 CFR 1.42, 37 CFR 1.43, 37 CFR 1.45, 37 CFR 1.46, 37 CFR 1.421, 37 CFR 1.422, 37 CFR 1.423, 37 CFR 1.424
For US national phase applications having an international filing date on or after 16 September 2012, the applicant may be:
(a) the inventor(s);
(b) the legal representative of a deceased or legally incapacitated inventor;
(c) the assignee;
(d) the obligated assignee (i.e., a person to whom the inventor is under an obligation to assign the invention); or
(e) a person who otherwise shows proprietary interest in the application.
For such applications, the person identified in the international stage as the applicant will normally be considered the applicant for the US national phase application, even if such applicant is not the inventor.
US.02
Where the applicant is a person who otherwise shows sufficient proprietary interest in the matter, such applicant must submit a petition including: the applicable fee, a showing that such person has sufficient proprietary interest in the matter, and a statement that making the application for patent by a person who otherwise shows sufficient proprietary interest in the matter on behalf of and as agent for the inventor is appropriate to preserve the rights of the parties.
US.03 INVENTORS
For US national phase applications with an international filing date prior to 16 September 2012, the inventor(s) is required to be the applicant(s) or, if an inventor is dead, insane, or otherwise legally incapacitated, such inventor’s legal representative. This is true even if the national phase documents are filed after 16 September 2012.
US.04
37 CFR 1.41
The inventorship of a US national phase application having an international filing date on or after 16 September 2012 is the inventor or joint inventors set forth in an application data sheet accompanying the initial national phase submission (refer to paragraph US.06). If the initial national phase submission for an application with an international filing date on or after 16 September 2012 is not accompanied by a proper application data sheet, OR if the national phase application has an international filing date prior to 16 September 2012, the inventorship is the inventor or joint inventors set forth in the international application, which includes any change effected under PCT Rule 92bis.
US.05 FORM FOR ENTERING THE NATIONAL PHASE
The USPTO has available a special transmittal form, Form PTO-1390 (refer to Annex US.III), to accompany the fees and documents required for entering the national phase. Use of the Form PTO-1390 is strongly encouraged because the form clearly identifies the submission as a national phase entry filed under 35 USC 371, as required for proper processing (refer to paragraph US.11). In addition, the Form PTO-1390 provides applicants with a checklist of items generally required or potentially applicable to a national phase filing, as well as a mechanism to make specific requests that may be appropriate in a particular national phase application. For example, the Form PTO-1390 contains checkboxes to expressly request that national examination procedures begin immediately (refer to paragraph US.37), to instruct the USPTO not to enter amendments made in the international phase, and to assert small entity status (refer to paragraph US.20). Use of the Form PTO-1390 is not, however, required.
US.06 APPLICATION DATA SHEET (ADS)
37 CFR 1.76, 37 CFR 1.495(c)
Together with the Form PTO-1390 discussed above, applicants are also strongly encouraged to submit an “application data sheet” (ADS). The ADS facilitates electronic capture of the bibliographic data by the USPTO, thus leading to more accurate data recording and quicker processing by eliminating the need to have this data manually extracted from the application documents. An application data sheet form for use where the international filing date is on or after 16 September 2012 (Form PTO/AIA/14) and instructions for preparing the form can be found at: https://www.uspto.gov/patents/apply/forms
The Form PTO/AIA/14 is attached as Annex US.IV and the Form PTO/SB/14 is attached as Annex US.V.
US.07
In an application with an international filing date on or after 16 September 2012, an application data sheet is required to postpone submission of the required oath or declaration of the inventors (refer to paragraph US.26, below).
US.08 CORRESPONDENCE
37 CFR 1.1, 37 CFR 1.5, 37 CFR 1.6(d), 37 CFR 1.6(g), 37 CFR 1.8(a)(2)
It is preferable to file the required national phase items online using the USPTO’s Patent Electronic System, which currently comprises EFS-Web and Patent Center. The Patent Electronic System provides customers the ability to electronically file a variety of patent application documents directly to the USPTO, including those associated with US national phase entries under 35 USC 371. It is recommended that applicants continue to use the Form PTO-1390 when electronically filing documents for entry into the US national phase under 35 USC 371 (refer to paragraph US.05). More information regarding the electronic filing of US patent applications using the Patent Electronic System may be obtained at https://www.uspto.gov/patents/apply. Full technical support is available through the Patent Electronic Business Center (EBC) at (1-866) 217 91 97 from 6 a.m. to 12 Midnight Eastern Time, Monday – Friday (except federal holidays). EBC may be emailed anytime at ebc@uspto.gov. In the event that the Patent Electronic System is not available due to an outage, information regarding alternative filing methods may be obtained at https://www.uspto.gov/patents/apply/filing-online/filing-documents-during-outage.
US.09
Patent Center, which will replace EFS-Web, has the added capability of enabling the electronic filing of a sequence listing in Extensible Markup Language (XML) format. This capability is important in view of the implementation of WIPO Standard ST.26, incorporated into U.S. sequence rules 37 CFR 1.831 - 1.839, which require that a sequence listing filed in any national phase application that has an international filing date on or after 1 July 2022 be in XML format in compliance with ST.26. For all applications having an international filing date before 1 July 2022, a sequence listing may be filed as an ASCII text file (.TXT) in ST.25 format, as per 37 CFR 1.821 - 1.825, but not as an ST.26 XML file. The USPTO’s Patent Electronic System has a file size limit of 100 MB for sequence listings in text or XML format, which must be uploaded separately from other types of files. Sequence listing files that exceed 100 MB can be submitted on optical disc in accordance with 37 CFR 1.52(e) on the same day by using Priority Mail Express® from the USPS in accordance with 37 CFR 1.10, or by hand delivery. Note that it is not necessary to submit a copy of a sequence listing that is part of the description of the international application upon entry into national phase at the USPTO if the international application has been published by the International Bureau (IB); the USPTO will obtain a copy of the published international application, including the sequence listing, from the IB under PCT Article 20. The inclusion of a sequence listing as part of the description is indicated on the front page of the published international application. The Patent Electronic System has a file size limit of 25 MB per PDF file, but up to 60 documents of this size may be submitted in a single electronic package.
US.10
National phase documents may also be submitted by mail addressed to: Mail Stop PCT, Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450, USA. If the applicant has received a “Notice of Acceptance of Application Under 35 USC 371 and 37 CFR 1.495”, the reference to “Mail Stop PCT” should be deleted. If a US application number (e.g., 18/123,456) has been assigned, it should be indicated on the documents. If a US application number has not yet been assigned, the correspondence should state the name of the applicant, the international filing date, the international application number and the title of the invention. It is important to note that a copy of the international application used to enter the national phase and/or payment of the required basic national fee may NOT be submitted by facsimile.
US.11
35 USC 371, 35 USC 111, 37 CFR 1.495(g)
A submission to enter the US national phase under the PCT is required by the USPTO to contain a clear indication of this intention. The identification requirement is usually complied with if the Form PTO-1390 for entering the national phase is used (refer to paragraph US.05 above). The identification of the international application, in the declaration or oath of the inventor (refer to paragraph US.23), as a prior filed application for priority purposes, or otherwise, is not considered to be a sufficient indication of an intention to enter the national phase under the PCT. In accordance with 37 CFR 1.495(g), an initial application submission filed on or after 16 September 2012 that contains (e.g., in the application documents and/or the data entered in the Patent Electronic System) conflicting indications as between a new US national patent application under 35 USC 111(a) and a submission to enter the national phase under 35 USC 371 will be treated by the USPTO as a submission to enter the national phase under 35 USC 371. However, an initial application submission filed prior to 16 September 2012 that contains conflicting indications will be treated as a new US national patent application under 35 USC 111(a).
US.12 TRANSLATION (LATE FURNISHING OF)
35 USC 371(d), 37 CFR 1.492(i), 37 CFR 1.495(c), 37 CFR 1.495(d), 37 CFR 1.495(e)
If the applicant pays the basic national fee and a copy of the international application is received within the applicable time limit for national phase entry, but a translation of the international application has not been furnished by the applicant or is incomplete, a notice is sent to the applicant which sets a time period for furnishing the translation. The applicant can then timely furnish the translation provided that a processing fee is paid. The amount of the processing fee is indicated in Annex US.I. The time period set in the notice will be two months from the date of the notice or 32 months from the priority date, whichever is later. The time period set in the notice may be extended as provided for in 37 CFR 1.136(a) (refer to paragraph US.43(i), below). The requirement to provide a translation of the international application encompasses the sequence listing part of the description. If an ST.25 text file that contains non-English free text is part of the international application, the applicant should submit a translated sequence listing text file in which the non-English text is replaced with the English translation, and clearly identify the submission as a translation of the sequence listing part of the description. If an ST.26 XML sequence listing that is part of the international application contains one or more language-dependent qualifiers that do not include an English value, applicant should submit a translated sequence listing in which all language-dependent qualifiers have English values, and clearly identify the submission as a translation of the sequence listing part of the description. Where amendments to the claims have been filed with the International Bureau under Article 19 and the applicant fails to furnish a translation or copy (refer to the Summary of Requirements for Entry into the National Phase) of such amendments to the claims within the time limit for national phase entry, the amendments to the claims are considered to have been cancelled. A translation of any annexes, e.g. Article 34 amendments, to the International Preliminary Examination Report must be furnished prior to the expiration of the applicable time limit under PCT Article 39(1). However, a translation of the annexes may be provided during any time period set under 37 CFR 1.495(c) to furnish a translation of the international application, the inventor’s oath or declaration, the search fee, the examination fee, and/or the application size fee. If a translation of the annexes is not timely filed, the amendments contained in the annexes will be considered to be cancelled. However, such amendments may be reintroduced at a later stage (refer to paragraph US.33).
US.13 TRANSLATION (CORRECTION)
Errors in the translation of the international application can be corrected with reference to the text of the international application as filed (refer to National Phase, paragraphs 6.002 and 6.003). If the translation furnished to the USPTO was incomplete, refer to the preceding paragraph.
US.14 PAYMENT OF NATIONAL FEE
35 USC 371(d), 37 CFR 1.495(b), 37 CFR 1.6(d)(3), 37 CFR 1.8(a)(2)(i)(F)
The basic national fee must be paid within the time limit for entry into the national phase (refer to PCT Article 22(1) or 39(l)a)) which is 30 months after the priority date. This time limit may not be extended. If the basic national fee is not paid within the applicable time period, the application becomes abandoned as to the United States. An authorization to charge the basic national fee to a deposit account, credit card or any other means may NOT be submitted by facsimile.
US.15 SEARCH FEE
37 CFR 1.492(b)(1), 37 CFR 1.492(b)(2), 37 CFR 1.492(b)(3), 37 CFR 1.492(b)(4)
If the applicant pays the basic national fee and a copy of the international application has been received within the time limit for national phase entry, but the search fee has not been paid, a notice is sent to the applicant which sets a time period for furnishing the search fee. The applicant can then furnish the search fee provided a surcharge fee is paid. The amounts of the search fee and the surcharge are provided in Annex US.I. The period set in the notice is extendable as provided in 37 CFR 1.136(a) (refer to paragraph US.43(i)).
US.16 EXAMINATION FEE
37 CFR 1.492(c)(1), 37 CFR 1.492(c)(2)
If the applicant pays the basic national fee and a copy of the international application has been received within the time limit for national phase entry, but the examination fee has not been paid, a notice is sent to the applicant which sets a time period for furnishing the examination fee. The applicant can then furnish the examination fee provided a surcharge fee is paid. The amounts of the examination fee and the surcharge are provided in Annex US.I. The period set in the notice is extendable as provided in 37 CFR 1.136(a) (refer to paragraph US.43(i)).
US.17 APPLICATION SIZE FEE
37 CFR 1.492(j)
For any US national phase application or national application, where the specification and drawings exceed 100 sheets of paper, for each additional 50 sheets, or fraction thereof, an application size fee will apply. For a US national phase application, the application size fee is calculated on the basis of the number of sheets of specification and drawings in the published international application, without regard to the language of the publication. The specification includes the description, claims, and abstract. Certain other sheets typically present in the international publication are not taken into account in determining the application size fee, i.e., Article 19 amendments/statement, the international search report, and any additional bibliographic sheets (other than the cover sheet containing the abstract). The amount of the fee is in Annex US.I.
US.18 ADDITIONAL CLAIMS FEE
37 CFR 1.75(c), 37 CFR 1.492(d), 37 CFR 1.492(e), 37 CFR 1.492(f), 37 CFR 1.492(g), 37 CFR 1.121(c)
An additional claim fee is applicable for each independent claim in excess of three, for each claim in excess of 20, and for an application that contains multiple dependent claim(s). The number of additional claims for fee purposes must be computed on the basis of the claims valid at the beginning of the national phase (that is, where amendments have been filed, the claims as amended under PCT Article 19 or PCT Rule 66.1, 66.3 and 66.4 or the claims as amended in a preliminary amendment submitted in compliance with the applicable US regulations by the applicant upon entering the national phase under PCT Article 28 or 41). Where the applicant fails to pay the correct amount of the additional claims fee, the USPTO will send a notification of fee deficiency and invite payment of the fee at the amount applicable on the date of payment. To avoid abandonment, the fee must be paid or the claims canceled by amendment prior to the expiration of the time period set for reply to any notification of fee deficiency.
US.19 FEE REDUCTION FOR “SMALL ENTITY” OR “MICRO ENTITY”
37 CFR 1.27, 37 CFR 1.28, 37 CFR 1.29, 37 CFR 1.33, 37 CFR 1.492
Applicants having a “small entity” or “micro entity” status are entitled to a reduction of 60% or 80%, respectively, in certain fees.
US.20
“Small entity” status can be established by a single written assertion of entitlement to “small entity” status without use of a specialized form. “Small entity” status may also be established by checking the box provided on the application data sheet discussed in paragraph US.06 or the Form PTO-1390 for entering the national phase discussed in paragraph US.05, or by payment of the exact basic national fee for a small entity. For a US national phase application with an international filing date on or after 16 September 2012, parties who may assert “small entity” status include the applicant, a patent practitioner of record or a practitioner acting in a representative capacity, the inventor or a joint inventor (if the inventor is an applicant), or the assignee. Assertion of small entity status requires a determination of entitlement to that status. For a US national phase application with an international filing date prior to 16 September 2012, parties who may assert “small entity” status include a registered practitioner, one of the inventors, or a partial assignee (an assignee assertion of small entity status must be filed by a 37 CFR 1.33(b) party).
US.21
“Micro entity” status can be established under either the “gross income” or “institution of higher education” basis. Under either basis, an application must also satisfy the requirements for “small entity” status. Unlike “small entity” status, “micro entity” status cannot be established by a simple statement alleging entitlement to “micro entity” status, by checking the box provided on the application data sheet or the Form PTO-1390 for entering the national phase, or by payment of the exact basic national fee. Rather, a certification of entitlement to “micro entity” status must be submitted. The USPTO provides Forms PTO/SB/15A and PTO/SB/15B for use in certifying “micro entity” status. These forms are available on the USPTO Web site at: https://www.uspto.gov/patents/apply/forms; copies of the certification forms are also in Annex US.VI and US.VII. The certification of “micro entity” status must be executed by a party authorized under 37 CFR 1.33(b). It should be noted that a registered practitioner is required to sign the certification for any applicant that is a corporation or organization; an officer of an assignee corporate applicant, for example, is not authorized to sign the certificate of “micro entity” status.
US.22 FEES (MANNER OF PAYMENT)
37 CFR 1.23
The manner of payment of the fees indicated in the Summary and in this Chapter is outlined in Annex US.I. A copy of a Credit Card Payment Form (Form PTO-2038) and the instructions thereto is attached as Annex US.II. It should be noted that an authorization to charge the basic national fee to a deposit account, credit card or any other means may NOT be submitted by facsimile.
US.23 OATH OR DECLARATION OF THE INVENTOR
35 USC 115, 35 USC 371(c)(4), 35 USC 371(d), 37 CFR 1.497, 37 CFR 1.495(c), 37 CFR 1.63, 37 CFR 1.64
As a result of changes implemented by the America Invents Act (AIA), the requirements for the oath or declaration of the inventor depend on whether an application was filed before or after 16 September 2012. A sample of an appropriate declaration for use in applications with an international filing date on or after 16 September 2012 is provided in Annex US.VII. In addition, Box No. VIII(iv) of the PCT request form (PCT/RO/101) contains a “DECLARATION: INVENTORSHIP (only for the purposes of the designation of the United States of America).” The declaration contained in Box No. VIII(iv) of the PCT request form (PCT/RO/101) was updated in the 16 September 2012 revision of the PCT request form (PCT/RO/101) to comply with the revised US law. Accordingly, the “DECLARATION: INVENTORSHIP (only for the purposes of the designation of the United States of America)” contained in previous versions of the PCT request form (PCT/RO/101) does not comply with current US law and will not be accepted by the USPTO with respect to applications with an international filing date on or after 16 September 2012.
US.24
For applications with an international filing date on or after 16 September 2012, a “substitute statement” may be submitted in lieu of an oath or declaration of the inventors if the inventor is deceased, is under a legal incapacity, has refused to execute the oath or declaration, or cannot be found or reached after diligent effort (a sample “substitute statement” form is provided in Annex US.X).
US.25
For applications with an international filing date before 16 September 2012, if the applicant pays the basic national fee and a copy of the international application is received within the time limit for entry into the national phase, but an oath or declaration of the inventor is not furnished, a notice shall be sent to the applicant which sets a time period for furnishing the oath or declaration. The applicant can then furnish the oath or declaration provided that a surcharge is paid. The amount of the surcharge is indicated in Annex US.I. The time period set in the notice will be two months from the date of the notice or 32 months from priority date, whichever is later. The time period set in the notice is extendable as provided for in 37 CFR 1.136 (a) (refer to paragraph US.43(i)).
US.26
For applications with an international filing date on or after 16 September 2012, the submission of an “application data sheet” (refer to paragraph US.06) identifying each inventor and providing each inventor’s residence and mailing address will permit the applicant to postpone submission of the oath or declaration of the inventor (or substitute statement, if applicable) until the application is otherwise in condition for allowance. In such cases, the USPTO will issue a Notice Of Acceptance (Form PCT/DO/EO/903) and refer the application for publication and examination; however, the Notice Of Acceptance (Form PCT/DO/EO/903) will indicate that the oath or declaration requirement has not yet been satisfied.
US.27 POWER OF ATTORNEY
37 CFR 1.31, 37 CFR 1.32
No representation of the applicant by an attorney or agent is required where the applicant is an individual or individuals; however, a juristic entity (e.g., organizational assignee) must be represented by an attorney or agent. Where an attorney or agent is to represent an applicant, a power of attorney signed by the applicant/inventor to an attorney or agent registered to practice before the USPTO is required. Sample power of attorney forms for use in an application with an international filing date on or after 16 September 2012 (Forms PTO/AIA/80, 81 and 82) are in Annexes US.IX-XI. It is highly advisable to be represented by an attorney or agent.
US.28 INFORMATION DISCLOSURE STATEMENT
37 CFR 1.56, 37 CFR 1.97, 37 CFR 1.98
The applicant must (to be prudent) file with the USPTO, not later than three months from the date of entry of the national phase, an information disclosure statement. Such statement must disclose all information of which the applicant, or any other person substantively involved with the preparation of the application or its prosecution, is aware which is material to the patentability of the invention. Such information is material to patentability when it is not cumulative to information already of record in the application, and (1) it establishes, by itself or in combination with other information, a prima facie case of unpatentability of a claim; or (2) it refutes, or is inconsistent with, a position the applicant takes in (i) opposing an argument of unpatentability relied upon by the Office, or (ii) asserting an argument of patentability. A prima facie case of unpatentability is established when the information compels a conclusion that a claim is unpatentable by the preponderance of evidence, burden of proof standard, giving each term in the claim its broadest reasonable construction consistent with the description, and before any consideration is given to evidence which may be submitted in an attempt to establish a contrary conclusion of patentability.
US.29
The information disclosure statement must include:
(1) a listing (preferably on Forms PTO/SB/08a and 08b, refer to Annex US.XII) of patents, applications, publications or other information. US patents and US patent applications must be listed in a section separately from citations of other documents. Each page of the listing must include:
(i) the application number of the application in which the information disclosure statement is being submitted;
(ii) a column that provides a space, next to each document to be considered, for the examiner’s initials;
(iii) a heading that clearly indicates that the list is an information disclosure statement;
(2) a copy of each listed item except for US patents and US patent application publications;
(3) for each item listed which is not in the English language, a concise explanation of its relevance.
US.30
Applicants may also file an information disclosure statement via the Office’s electronic filing system (EFS-Web/Patent Center) by:
(1) entering the references’ citation information in a fillable electronic form equivalent to the revised Forms PTO/SB/08a and 08b; and
(2) transmitting the fillable electronic form data to the Office via EFS-Web/Patent Center.
US.31
35 USC 371, 37 CFR 1.97, 37 CFR 1.98
Note, however, that the examiner will consider the documents cited in the international search report in a PCT national phase application when the Form PCT/DO/EO/903 (which is sent to notify the applicant after he has entered the national phase of the acceptance of the international application under 35 USC 371) indicates that both the international search report and the copies of the prior art documents are present in the national phase file. In such a case, the examiner will consider the documents from the international search report and indicate by a statement in the first Office action that the information has been considered. There is no requirement that the examiner list the documents on a Notice of References Cited (Form PTO-892). In order to have these prior art documents printed on any resulting patent, the applicant must provide a separate listing (preferably on Forms PTO/SB/08a and 08b). If Form PCT/DO/EO/903 does not indicate that both the international search report and copies of the prior art documents are present in the national stage file, the applicant must follow the procedures set forth in 37 CFR 1.97 and 1.98 (concerning the filing and content of information disclosure statements), as outlined above, in order to ensure that the examiner considers the documents cited in the international search report.
US.32
37 CFR 1.97(e)
A translation into English of the pertinent portions in a non-English language document must be transmitted if an existing translation is readily available to the applicant. Any additional information material to the claimed invention which becomes available after the transmittal of the statement should, within three months of its availability, be submitted by a supplemental information disclosure statement. Failure to disclose completely any pertinent information may result in any resulting US patent based on the application being unenforceable. A fee or an appropriate statement under 37 CFR 1.97(e) is required if an information disclosure statement is submitted more than three months after entry to the national stage and after a first Office action is mailed, but before a final Office action or a notice of allowance is issued. After a final Office action or a notice of allowance has been issued but before payment of the issue fee, a fee and an appropriate statement under 37 CFR 1.97(e) will be required to have an information disclosure statement considered.
US.33 AMENDMENT OF THE APPLICATION; TIME LIMITS
PCT Art. 28
The applicant may make the following amendments, provided no new matter is introduced in the disclosure of the invention:
35 USC 133, 37 CFR 1.111, 37 CFR 1.112, 37 CFR 1.113, 37 CFR 1.114, 37 CFR 1.115, 37 CFR 1.116, 37 CFR 1.117, 37 CFR 1.118, 37 CFR 1.119, 37 CFR 1.120, 37 CFR 1.121, 37 CFR 1.122, 37 CFR 1.123, 37 CFR 1.124, 37 CFR 1.125, 37 CFR 1.126, 37 CFR 1.127
(i) before the final decision of the USPTO to grant or to reject the patent, the applicant may file amendments to the description, claims and drawing(s) of his own volition or when specifically required by the examiner;
37 CFR 1.116
(ii) after the final decision, amendments may be made only by cancelling claims or complying with any requirement of form which has been made by the examiner, or by presenting rejected claims in better form for reconsideration on appeal.
US.34
37 CFR 1.121, 37 CFR 1.125
For the manner of making amendments and the required format, refer to the applicable US regulations, in particular 37 CFR 1.121 and 1.125. One of the requirements for effectively amending claims in a national phase application is a complete listing of all claims ever presented, including the text of all pending and withdrawn claims. The status of every claim in such listing must be indicated after its claim number by one of the following identifiers in a parenthetical expression: (Original), (Currently Amended), (Canceled), (Withdrawn), (Previously Presented), (New), and (Not Entered). All “currently amended” claims must include markings to indicate the changes made relative to the immediate prior version of the claims: underlining to indicate additions, strike-through or double brackets for deletions (refer to 37 CFR 1.121(c) for further details regarding the format of claim amendments). Applicants should note that, in an amendment to the claims filed in a national phase application, the status identifier “original” must be used for claims that had been presented on the international filing date and not modified or canceled. The status identifier “previously presented” must be used in any amendment submitted during the national phase for any claims added or modified under PCT Articles 19 or 34 in the international phase that were subsequently entered in the national phase. The status identifier “canceled” must be used in any amendment submitted during the national phase for any claims canceled under an Article 19 or 34 amendment in the international phase and subsequently entered in the national phase.
Example 1: Original claims 1-10; Article 19/34 filed with claims 1-20 listed on the replacement sheet wherein claims 1-10 were unchanged and claims 11-20 were added; the status of the claims prior to any further amendment under 37 CFR 1.121 would be as follows: claims 1-10 as “original” and claims 11-20 as “previously presented.”
Example 2: Original claims 1-10; Article 19/34 filed with claims 1-9 listed on the replacement sheet wherein claims 1-9 were unchanged and claim 10 was cancelled; the status of the claims prior to any further amendment under 37 CFR 1.121 would be as follows: claims 1-9 as “original” and claim 10 as “cancelled.”
Example 3: Original claims 1-10; Article 19/34 filed with claims 1-9 listed on the replacement sheet wherein claim 1 was unchanged, claim 2 was cancelled and claims 3-10 were renumbered as claims 2-9; the status of the claims prior to any further amendment under 37 CFR 1.121 would be as follows: claim 1 as “original, ”, claims 2-9 as “previously presented” and claim 10 as “cancelled.”
Example 4: Original claims 1-10; Article 19/34 filed with claims 1-10 listed on the replacement sheet wherein claims 1 and 3-10 were unchanged and claim 2 was cancelled; the status of the claims prior to any further amendment under 37 CFR 1.121 would be as follows: claims 1 and 3-10 as “original” and claim 2 as “cancelled.”
Proposed amendments that are not submitted in compliance with the applicable regulations will not be entered. For example, the submission with the national phase documents of a revised set of claims, absent a preliminary amendment to the claims in compliance with 37 CFR 1.121(c), will not be effective to amend the claims of record in the application.
US.35 FEE FOR GRANT
37 CFR 1.18
A patent issue fee and any required publication fee must be paid within a nonextendable period of three months after the mailing of a written notice of allowance. The amount of the said fee is indicated in Annex US.I.
US.36 MAINTENANCE FEES
37 CFR 1.20
After a patent has been issued, a fee must be paid for maintaining the patent in force beyond four years after grant. The first such fee is due by three years and six months after issue of the patent. Where the applicant fails to pay within that time limit, he may receive an invitation to pay from the USPTO. Lack of receipt of such an invitation will not be accepted as an excuse for non-payment of the maintenance fee. Payment can then still be made together with a surcharge within the six months following the due date. The amount of the maintenance fees, of the surcharge, and their due dates are indicated in Annex US.I.
US.37 EARLY START OF NATIONAL PHASE BEFORE THE USPTO
PCT Art. 23(2), 35 USC 371(f)
If the applicant desires the examination by the USPTO of his application to start earlier than the expiration of the time limit for entry into the national phase, he must file in writing an express request therefor and submit the basic national fee, a copy of the international application, a translation of the international application (if required) and an oath or declaration of the inventor. The express request may be accomplished, for example, by checking the appropriate box on the Form PTO-1390 for entry into the national phase referred to in paragraph US.05 and reproduced in Annex US.III.
US.38
The mechanism for deferring submission of the oath or declaration of the inventor by filing an “application data sheet” (refer to paragraph US.26) is not applicable where the applicant requests early examination by the USPTO. Such early examination of the application requires submission of the oath or declaration (or the substitute statement, if applicable).
US.39 CONTINUATION, CONTINUATION-IN-PART OR DIVISIONAL
35 USC 111, 35 USC 120, 35 USC 365(c), 35 USC 371(c), 37 CFR 1.76, 37 CFR 1.78, 37 CFR 1.495(h)
The applicant may—instead of entering the national phase—file a continuation, continuation-in-part or divisional of the international application (hereinafter referred to as “the continuing application”), provided the international application designates the US and is not (considered) withdrawn or abandoned at the time of filing the continuing application. An international application is considered abandoned after the expiration of the time limit for entry into the national phase, which is 30 months after the priority date, if a copy of the international application and the basic national fee have not been received in the USPTO. When the basic national fee has been paid and a copy of the international application has been communicated by the International Bureau within the time limit for entry into the national phase, but additional national phase requirements have not been submitted (e.g., an English translation and/or additional required fees), a notice will be sent to the applicant to furnish such additional required materials. If the applicant does not properly respond to the notice within the time period set by the USPTO, the international application will become abandoned.
US.40
Basically, the normal procedure for filing continuing applications applies. The applicant must submit an application data sheet (refer to paragraph US.06) claiming the benefit of the international filing date of the international application designating the US. The reference to the international application in the application data sheet must identify the international application by international application number and international filing date, and it must indicate the relationship of the applications (i.e., continuation, continuation-in-part, or divisional). This reference to the international application must be submitted during the pendency of the continuing application, and within the later of four months from the actual filing date of the continuing application or sixteen months from the filing date of the international application. This time limit is not extendable. The USPTO may require the filing of a certified copy of the international application together with a translation thereof into English where it was filed in another language. The continuing application may be filed in a language other than English, provided a translation into English is furnished together with a surcharge (refer to Annex US.I) within the time period fixed by the USPTO in an invitation. Where, at the time of filing the continuing application, the basic filing fee has not been paid or the oath or declaration of the inventor has not been furnished, the requirement may still be complied with against payment of a surcharge within the time period fixed by the USPTO in an invitation. Use of the Form PTO-1390 reproduced in Annex US.III is not appropriate for the filing of a continuing application.
US.41 REVIEW UNDER ARTICLE 25 OF THE PCT
PCT Art. 25, PCT Rule 51, 35 USC 367, 37 CFR 1.182
The applicable procedure is outlined in paragraphs 6.018 to 6.021 of the National Phase. If, upon review under PCT Article 25, the USPTO finds no error or omission on the part of the receiving Office or the International Bureau, a petition may be taken to the Commissioner of the USPTO, which must contain a statement of the facts involved and the point or points to be reviewed and the action requested. The fee for petition indicated in Annex US.I must be paid at the same time. Any such petition not filed within two months from the action complained of may be dismissed as untimely.
US.42 EXCUSE OF DELAYS IN MEETING TIME LIMITS
PCT Art. 48(2), PCT Rule 82bis, 37 CFR 1.137
An application abandoned for failure to comply with a time limit during the international phase or for failure to prosecute within a statutory time period before the USPTO, may be revived as a pending application if it is shown to the satisfaction of the USPTO that the delay was unintentional. Any petition to revive an abandoned application must be filed in writing and be accompanied by a petition fee, the amount of which is indicated in Annex US.I, by a proper response to the failed action unless such response has been previously submitted and by a statement indicating that the entire delay was unintentional. The USPTO has provided Form PTO/SB/64PCT (refer to Annex US.XVI) for use as a petition to revive an unintentionally abandoned international application (use of the form is optional).
US.43
The US rules provide for two distinct procedures to extend the period for action or response in particular situations (the procedure which is available for use in a particular situation will depend upon the circumstances):
37 CFR 1.136
(i) 37 CFR 1.136(a) permits an applicant, against payment of an extension fee (refer to Annex US.I), to file a petition for extension of time up to five months after the end of the time period set to take action except
(1) where excluded,
(2) in interference proceedings,
(3) where the applicant has been notified otherwise in an Office action or
(4) where no further time is available under a set statutory period.
The petition and fee can be filed prior to or with or after the response, but the fee must be paid within the time extended. The filing of the petition and fee will extend the time period to take action up to five months dependent on the amount of the fee paid except in those circumstances noted above. The time limit to furnish the basic national fee and a copy of the international application under 37 CFR 1.495 may not be extended.
(ii) After entry into the national phase, 37 CFR 1.136(b) provides for petitions for extensions of time of shortened statutory or non-statutory time periods upon a showing of sufficient cause when the procedure of 37 CFR 1.136(a) is not available and if additional time is still available under a shortened statutory period or if no statutory period applies.
Although the petition and fee procedure of 37 CFR 1.136(a) will normally be available within five months after a set period for response has expired, an extension request for cause under 37 CFR 1.136(b) must be filed during the set period for response. The amount of the petition fee is indicated in Annex US.I.
US.44 RECORDING OF ASSIGNMENT DOCUMENTS
37 CFR 3.21, 37 CFR 3.24, 37 CFR 3.28, 37 CFR 3.31
The USPTO will record assignments relating to international patent applications which designate the US. The assignment must identify the application by the international application number. Each document submitted for recording must be accompanied by a cover sheet referring to the international application. A sample recordation form cover sheet is contained in Annex US.XV. Each cover sheet must contain:
1) the name of the party conveying the interest;
2) the name and address of the party receiving the interest;
3) a description of the interest conveyed or transaction to be recorded;
4) the application number;
5) the name and address of the party to whom correspondence concerning the request to record the document should be mailed;
6) the number of applications, patents or registrations identified in the cover sheet and the total fee;
7) the date the document was executed;
8) a statement by the party submitting the document that to the best of the person’s knowledge and belief, the information contained on the cover sheet is true and correct and any copy submitted is a true copy of the original document; and
9) the signature of the party submitting the document.
US.45
Assignments may be filed electronically via the Electronic Patent Assignment System (EPAS). EPAS may be accessed directly at the following web address: https://epas.uspto.gov. General information about the electronic filing of assignments may be obtained from the Assignment Services Division Customer Service Desk at (1-571) 272-3350 during regular business hours or via e-mail directed to EPAS@uspto.gov. Applicants should note that assignments may NOT be filed via the EFS-Web/Patent Center electronic filing system.
US.46 PUBLICATION OF APPLICATIONS
37 CFR 1.211, 37 CFR 1.213, 37 CFR 1.221
Each international application in compliance with 35 USC 371 and continuing application (refer to paragraph US.39) from an international application will be published promptly after the expiration of eighteen months from the earliest filing date for which a benefit is sought, unless the application (1) is no longer pending; (2) is subject to national security provisions; (3) has issued as a patent; or (4) was filed with a nonpublication request in compliance with 37 CFR 1.213(a). (A nonpublication request may not be filed if the international application designated any States in addition to or other than the United States of America.) The publication fee (refer to Annex US.I) must be paid before the patent will be granted. If the application is not published under this section, the publication fee (if paid) will be refunded.
US.47 PROVISIONAL RIGHTS
35 USC 154(d), 37 CFR 1.417
35 USC 154(d) provides for provisional rights based on international applications. A patent will include the right to obtain a reasonable royalty from any person who partakes of any of the actions listed in 35 USC 154(d)(1) during the period commencing on the date of the publication under PCT Article 21(2)(a) of the international application designating the US, if the publication is in English, or if the publication is in a language other than English, on the date the USPTO receives a translation of the publication in the English language, and ending on the date the patent is issued. The submission of the international publication or an English language translation of the international application pursuant to 35 USC 154(d)(4) must clearly identify the international application to which it pertains (37 CFR 1.5(a)) and, unless it is being submitted pursuant to 37 CFR 1.495, be clearly identified as a submission pursuant to 35 USC 154(d)(4). Otherwise, the submission will be treated as a filing under 35 USC 111(a). Such submissions should be marked “Mail Stop PCT.” The right to obtain a reasonable royalty is not available unless the invention as claimed in the patent is substantially identical to the invention claimed in the published international application.

How can payment of fees be effected?
All payments must be made in USD
Any payment may be effected by:
— United States Postal Service money order (37 CFR 1.23)
— check (37 CFR 1.23)
— USPTO deposit account (37 CFR 1.25)
— credit card (37 CFR 1.23(b))
Money orders and checks must be payable in United States dollars to the “Director of the U.S. Patent and Trademark Office.” Remittance from foreign countries must be payable and immediately negotiable in the United States of America for the full amount of the fee required. All payments must indicate the complete application number, the name of applicant and the type of fee being paid
Payment for all fees may be made using one of the following credit cards: MasterCard, VISA, American Express and Discover. Payment using a debit card or check card will not be accepted. Applicants making payments by credit card should use form PTO-2038 contained in this Annex. Blanket authorizations of payments to credit cards will not be accepted. The fee amount must be specified. Credit card authorization may be used only one time. Subsequent charges will require a new authorization. ADVISORY: If filing by EFS-Web/Patent Center, do NOT attach the PTO-2038 form as a PDF along with your EFS-Web/Patent Center submission. Please be advised that this is not recommended and by doing so your credit card information may be displayed via PAIR. To protect your information, it is recommended paying fees online by using the electronic payment method. The PTO-2038 should only be mailed or faxed to the USPTO. The PTO-2038 may not be faxed to the USPTO when paying the basic national fee.
For information concerning electronic transfer of funds to the USPTO, please contact Jusu Jallah, Office of Finance at:
(571) 272-7473 or (571) 272-6500
fax (571) 273-7473
Applicants choosing to pay by electronic transfer should ensure that the full amount of the fee due is received by the USPTO. There is a danger of loss of rights if bank charges are deducted
