Main procedures for PCT international application

Overview of PCT International Applications and Procedure Periods

Flowchart

 
 

 

international application

The international application system allows you to apply to all PCT member countries by submitting one application document prepared in your native language (Japanese or English if the receiving office is the Japan Patent Office) to one patent office. This is a system that provides the same effect as filing an application (Article 3 of the Convention, etc.).

International application documents

An international application includes a request, specification, claims, necessary drawings, and abstract (Article 3(2) of the Convention). Each document must meet certain formatting requirements.

Additionally, international applications must be filed in a language recognized by the receiving Office in which they are filed (Articles 3(4) and 11(1)(ii) of the Convention). In Japan, application documents must be prepared in Japanese or English.

Where to submit your international application

An international application may be filed with the national office (receiving Office) of a contracting state if the applicant is a resident or national of that state (Articles 9 and 10 of the Convention). In Japan, an international application can be filed with the Japan Patent Office (receiving office) if at least one of the applicants in the international application is a Japanese citizen or resident.

Additionally, the International Bureau of WIPO accepts international applications from nationals or residents of all PCT member states as a receiving office.

Recognition of international filing date

The receiving Office will recognize the international filing date if the international application has been prepared in accordance with the PCT Treaty and Regulations. The requirements for recognition of the international filing date are specifically enumerated in Article 11(1)(i)-(iii) of the Convention.

An international application whose international filing date has been recognized has the effect of being a regular national application in each designated country from the international filing date, and the international filing date is considered to be the actual "filing date" in each designated country ( Article 11(3),(4) of the Convention). This allows applicants to receive the same benefits as filing directly in each designated country by filing one international application with one receiving Office.

An international application with a recognized international filing date is deemed to have designated all PCT member countries valid as of the filing date (deemed all designation).

Fees

Applicants for international applications must pay 1) international application fees (fees for the WIPO International Bureau to process application documents) and XNUMX) transmission fees (for the receiving Office to process application documents and submit required documents) within one month of filing. ③Search fee (fee for international search) must be paid to the receiving Office.

When filing an international application with a Japanese receiving office, all fees must be paid in Japanese yen.

 
 

 

international search

The international search system is a system in which the competent international search authority conducts a search for all international applications for which the international filing date has been recognized, with the aim of discovering prior art related to the claimed invention. (Articles 15 to 19 of the Convention, etc.).

international search report

The International Searching Authority shall provide a list of prior art found to be relevant or documents describing the relevant technology, a classification of the invention (International Patent Classification), the technical field in which the search was conducted, and information regarding the lack of unity of invention. An international search report containing information will be prepared and sent to the applicant (Article 18(2) of the Convention). The international search report will help you decide whether to proceed with the international application or consider withdrawing the designated countries.

The international search report will be prepared within 3 months from the receipt of the search copy by the International Searching Authority or 9 months from the priority date, whichever is later.

Opinion by the International Searching Authority (written international search opinion)

The International Searching Authority determines whether the invention stated in the claims of the international application is deemed patentable (novelty, inventive step, industrial applicability) (determining patentability of each requirement , priority date is the reference date) will be prepared and sent to the applicant. Similar to the international search report, the international search opinion helps in deciding whether to proceed with the international application or in considering withdrawal of designated countries.

The opinion on patentability expressed in the written international search opinion is preliminary and non-binding, so the final determination of patentability is left to each designated office.

The international search opinion, like the international search report, is prepared within 3 months from the receipt of the search copy by the International Searching Authority or 9 months from the priority date, whichever is later.

supplementary international search

In addition to the above-mentioned international searches, there is a supplementary international search, which provides for an international search by another International Searching Authority at the applicant's voluntary request.

By requesting a supplementary international search, additional prior art can be identified during the international phase, thereby reducing the possibility that new prior art documents will be discovered during the national phase.

When requesting a supplementary international search, the applicant must submit a request form (PCT/IB/19) and pay the prescribed fee to the International Bureau of WIPO within 375 months from the priority date. If a supplementary international search is requested, the Supplementary International Searching Authority will draw up a supplementary international search report within 28 months from the priority date.

 

 

international release

The international publication system is a system in which, in principle, the International Bureau publishes the contents of international applications in a uniform manner in a prescribed language and format 18 months after the priority date (Article 21 of the Treaty). This international publication serves to provide technical information to third parties. The applicant may also request international publication (early publication) before the expiration of 18 months from the priority date (Article 21(b) of the Convention).

Contents of international release

The contents to be internationally published are: (19) bibliographic page (front page with information such as international filing date, international application number, applicant, designated country, abstract, etc.), (21) full text of description, claims, and drawings, and (3) international search. Report, ④ If there is an amendment to Article 4 of the Convention, the amended scope of claims, etc. (Article 30(XNUMX), (XNUMX) of the Convention). The international search opinion will be available for inspection after XNUMX months from the priority date.

International publication language

International applications filed in "Japanese, Arabic, Chinese, English, French, German, Russian, Spanish, Korean, and Portuguese" will be published internationally in that language. International applications filed in languages ​​other than these will be published in one of the publication languages ​​translated by the applicant.

Even if the international application is filed in a language other than English, the title of the invention, abstract, and international search report will be published in both the relevant language and English translations.

Effect

In addition to internationally publishing inventions that have already been filed, international publication has the same effect as that provided by the domestic laws of each designated country regarding compulsory domestic publication of unexamined domestic applications. (Article 29 of the Convention).

For example, under the domestic law of a designated country that grants "provisional protection" upon publication of a national application, the same protection is granted to an international application that is published internationally.

In Japan, if a Japanese language international application is published internationally (or a foreign language patent application is published domestically), the right to claim compensation arises (Article 184-10 of the Patent Law).

 

 

international preliminary examination

The International Preliminary Examination System provides, at the applicant's request, a preliminary and non-binding opinion regarding the patentability (novelty, inventive step, industrial applicability) of an invention claimed in an international application. This is the system provided by the competent International Preliminary Examining Authority (Articles 33 to 35 of the Convention, etc.). The international preliminary examination provides a more advanced opinion on the substantive content than the international search.

Request for international preliminary examination

When requesting an international preliminary examination, the applicant must file an international You must submit a request for preliminary examination and pay the fee.

Other effects

By requesting an international preliminary examination, it becomes possible to (34) make amendments to the description, drawings, and claims (Article XNUMX of the Treaty), and (XNUMX) submit a written reply.

 

 

correction

The PCT allows amendments to improve the subject matter of the invention after a filing date has been secured. Therefore, applicants can amend their application contents to reflect, for example, (1) market trends, (2) matters pointed out in the international search and international preliminary examination, and (3) trends in international standards. .

The PCT allows amendments under Article 19 of the Treaty and amendments under Article 34 of the Treaty in the international phase. Furthermore, amendments after the national phase procedure are allowed.

 

Article 19 amendment, Article 34 amendment

After receiving the international search report, the applicant may amend the claims of the international application pursuant to Article 19 of the Convention. In addition, the applicant may submit a brief explanation explaining the content of the amendment, if necessary.

In addition, an applicant who has requested an international preliminary examination may submit the description, claims, and drawings of the international application within the prescribed period before the international preliminary examination report is prepared, pursuant to Article 34 of the Convention. It can be corrected.

A comparison of the amendments based on Article 19 of the Convention and the amendments based on Article 34 of the Convention is as follows.

Amendments after national entry

Applicants who have completed the national phase can make amendments at each designated Office based on Article 28 (and Article 41) of the Convention. However, in this case, the scope, period, procedures, etc. of amendments will be subject to the domestic laws and regulations of each designated country. In Japan, amendments under Article 17 of the Patent Law fall under this category, and the principle is that amendments can be made as long as the international application is pending with the Patent Office.

 

 

Domestic migration

An international application has the same effect as filing in multiple countries at the same time by filing one application with one receiving office. However, the PCT leaves substantive requirements to the domestic laws of each designated country, and each designated country makes the final decision on whether to grant a patent. Therefore, in order to seek the grant of a patent in each designated country, it is necessary to take steps to move the procedure from the international phase to the national phase of each designated country.

Migration deadline

The national transition to the designated country in which you wish to acquire rights must be carried out within the period determined by the Convention (Articles 22(1) and 39(1)(a) of the Convention).

In principle, the period specified by the treaty is within 30 months from the priority date, but in Europe it is stipulated to be within 31 months. In addition, for Luxembourg, Uganda, and Tanzania, unless a request for international preliminary examination is filed, the deadline is 20 months (or 21 months) from the priority date (as of March 2010).

procedure

Procedures for transferring an international application to the national phase include the following procedures with the designated office. However, regarding ③, fewer countries, including Japan, actually make the request.

① Submission of translated text

If the language in which the international application is drawn up is not a language recognized by the designated country in which you wish to enter the national phase, it must be translated into the language in which the international application is recognized.

②Payment of domestic fees

Domestic fees must be paid if required by the national laws of the designated country.

③ Submission of a copy of the international application

This may be required if the designated State has not yet obtained a copy of the international application from the International Bureau of WIPO.

Effect

If the national phase procedure is completed within the prescribed period, the international application will be treated in the same way as a national application in the designated country where the national phase has occurred. Therefore, after entering the country, procedures must be carried out in accordance with the domestic laws and regulations of those countries.

Furthermore, since most designated offices restrict foreigners from filing procedures directly with the Patent Office, domestic laws and regulations require that domestic procedures be carried out by appointing an agent in the designated country. (In Japan, Patent Law Article 184-11).

On the other hand, if the applicant does not carry out the national phase procedure within the prescribed period, the international application lapses with respect to the designated countries in which there was no national phase, with the same effect as the withdrawal of the national application in that country (in many cases , the international application shall be considered withdrawn) (Article 24 of the Convention).

 

 

 

 

Other specific procedures

 

Procedures for partial refund of international search fees

If the International Searching Authority is able to use a significant portion of the examination results of the national application or the search results of the international application, which are the basis of the priority claim, in preparing the international search report, a portion of the international search fee will be refunded. (Rule 16.3).

1. When filing an international application, please include a "Request for Use of Previous Search" in the application form.
2. If the examiner of the International Searching Authority determines that the earlier search results can be used, he/she will issue a notification to that effect to the applicant.
3. The applicant submits a "Request for Partial Refund of International Search Fees" to the Japan Patent Office (International Searching Authority).
Four. A portion of the international search fee paid at the time of international application (for applications made after April 4, 2012, 4 yen of the 1 yen international search fee) will be returned to the applicant.

If you wish to request the use of the examination results of an earlier national application, please submit the following information at the earliest possible stage before the start of the international search: (1) Request for examination of the earlier national application and (2) Withdrawal of the designation of Japan in the international application. You need to complete the procedure.

Additionally, if you request the use of the search results of an earlier international application, the International Searching Authority that searches the earlier international application must be the Japan Patent Office.

If the International Searching Authority is the European Patent Office, please check the relevant WIPO website.

Name change procedure

Information regarding the applicant, such as the applicant's name, inventor's name, and addressee name, can be changed during the international phase by submitting a change of name notification (Rule 92.2-1).

The name change notification should be submitted to the Japan Patent Office (receiving office) or WIPO (International Bureau). If submitted to the Japan Patent Office, the Japan Patent Office will send it to WIPO.

Please note that the name change notification will ultimately be accepted by WIPO, so submitting it directly to WIPO will allow the name change to be reflected more quickly. In particular, if you wish to have the information after the name change published in the International Publication Bulletin, which is about to be published, we recommend that you submit it directly to WIPO.

If you change your name at the international stage, each transition country will be notified of the changed details with just one procedure, and there is no need for notary certification or the submission of a power of attorney, so you can change your name in each transition country. The procedure will be simpler than when doing so.

 

 

Information provision

After the international application has been published, information regarding the novelty and inventive step of the invention related to the international application can be provided through the electronic system provided by WIPO (International Bureau) within 28 months from the priority date. Please note that the information provided is limited to information regarding novelty and inventive step, but it is useful for speeding up the examination and eligibility.

The information provided will be sent to each international organization (the competent International Searching Authority before the preparation of the international search report and the competent International Preliminary Examining Authority before the preparation of the international preliminary examination report) and made available to the public.

Applicants can submit comments regarding the information provided to WIPO (International Bureau).

 

 

Avoidance of deemed withdrawal

In principle, an international application is deemed to have designated all PCT contracting states (deemed all designation). If you file an international application claiming priority based on a Japanese domestic application, you are claiming domestic priority, and the earlier domestic application was withdrawn 1 year and 3 months after the earlier filing date. (Articles 41 and 42 of the Patent Law).

Therefore, if you wish to proceed with acquiring rights in Japan using an earlier domestic application, you will need to avoid the deemed withdrawal of the earlier domestic application by using one of the methods below.

 

Method 1: Exclusion of Japan designation

You can exclude the designation of Japan by checking the checkbox provided in the international application form (Column V). As a result, the international application will not designate Japan, so the earlier domestic application on which the domestic priority is based will not be deemed withdrawn.

However, please note that if you check this checkbox to remove the designation of a designated country, you will not be able to reinstate the designation of the designated country.

Method 2: Withdrawal of Japan's designation

Japan's designation can be withdrawn by submitting a "Designation withdrawal form" to the receiving office at least 1 year and 3 months from the earlier filing date when the earlier domestic application is deemed to be withdrawn. can. As a result, the international application will not be able to enter the national phase in Japan, so the earlier domestic application that forms the basis of the domestic priority will not be deemed to be withdrawn.

Method 3: Withdrawal of domestic priority claim

A claim for domestic priority can be withdrawn by submitting a written statement to the receiving office 1 year and 3 months from the filing date of the earlier domestic application, when the earlier domestic application is deemed to be withdrawn. As a result, both the earlier domestic application that is the basis of the domestic priority and the international application that has entered the national phase will be pending in Japan's domestic procedures, regardless of the priority.

 

 

Restoration of priority

Even if an international application claiming priority is filed beyond the 12-month priority period, if the international filing date is within 2 months of the expiry of the priority period, the application will be immediately invalidated. During the international phase, the priority claim is maintained (Rule 26bis.2.2).

However, in order for the priority claim maintained in this way to be valid after entering the national phase, the applicant must claim the priority claim to the Japan Patent Office and the International Bureau as receiving Offices or to each designated Office. (Article 49-3).

(From April 1, 2015, it is now possible to request restoration of priority to the receiving office, the Japan Patent Office.)

In order for priority to be restored, the following conditions must be met (Rule 26, 2.3).

  • The international application must have been filed within two months of the expiry of the 12-month priority period.
  • The reason for failure to comply with the priority period must meet the ``criteria for recovery'' adopted by each agency (e.g., ``unintentional,'' ``despite taking due care as required by the circumstances.'') )
  • The request for priority restoration, the reason why the international application was not filed within the priority period, and evidence supporting the reason must all be submitted within two months from the expiration of the priority period.

In principle, priority rights restored by the Japan Patent Office as a receiving Office that adopts the “due diligence” standard are valid in designated countries that do not reserve the provisions of PCT Rule 49ter.3.1. (Regulation 49, 3.1(a)(c)(d)).

If you wish to request restoration of priority with the International Bureau as a receiving Office that adopts the "unintentional" standard, you will need to file an international application with the International Bureau.

Please note that South Korea and China are subject to transitional measures. *1

Please check the relevant WIPO website for the latest information on countries applying transitional measures.

http://www.wipo.int/pct/en/texts/reservations/res_incomp.html

※ 1

  • The receiving authorities have declared the application of transitional measures to 14 countries: Belgium, Brazil, Colombia, Cuba, Czech Republic, Germany, Algeria, Greece, Indonesia, India, Italy, South Korea, Norway, and the Philippines.
  • The 15 countries that have declared application of transitional measures at designated authorities are Brazil, Canada, China, Colombia, Cuba, the Czech Republic, Germany, Algeria, Indonesia, India, South Korea, Mexico, Norway, the Philippines, and Turkey.

 

 

Correction (supplementation)/addition of priority claim

It is possible to correct or add priority claims that were incorrectly claimed or failed to be claimed when filing the international application (Rule 26bis).

In principle, corrections and additions to priority claims can be made within four months from the international filing date. However, if the earlier of (A) or (B) below expires later than the principle (4 months from the international filing date), the principle does not apply and the earlier of (A) or (B) expires later than the principle (XNUMX months from the international filing date). Corrections and additions are permitted until the expiration date.

(A) 16 months from the priority date claimed in the application;
(B) 16 months from the new priority date as changed by correction or addition of priority claim;

Procedures are carried out at the Japan Patent Office (receiving office) or WIPO (International Bureau). When filing procedures with the Japan Patent Office, if there is an error in the indication of the priority claim, submit a "procedural amendment", and if you wish to add a priority claim, submit an "application for addition of priority claim". .

Please note that when filing procedures with WIPO, there is no prescribed format for the document, so submit it in the form of a letter.

 

Withdrawal of priority claim

The applicant may withdraw the priority claim until the expiry of 30 months from the priority date (Rule 90bis.2.3). If two or more priority rights are involved, any or all of them can be withdrawn.

Procedures are carried out at the Japan Patent Office (Receiving Office), WIPO (International Bureau), or where Article 39(1) of the Convention applies, the Japan Patent Office (Preliminary Examining Authority) or the European Patent Office (Preliminary Examining Authority). Do it for. When proceeding with the Japan Patent Office, a "Letter of Withdrawal of Priority Claim" will be submitted.

Please note that when filing procedures with WIPO or the European Patent Office, there is no prescribed format for the document, so submit it in the form of a letter.

 

Withdrawal of international application

The applicant may withdraw the international application until the expiry of 30 months from the priority date (Rule 90bis.2.1).

Procedures are carried out at the Japan Patent Office (Receiving Office), WIPO (International Bureau), or where Article 39(1) of the Convention applies, the Japan Patent Office (Preliminary Examining Authority) or the European Patent Office (Preliminary Examining Authority). Do it for. When proceeding with the Japan Patent Office, a "Letter of Withdrawal of International Application" must be submitted.

Please note that when filing procedures with WIPO or the European Patent Office, there is no prescribed format for the document, so submit it in the form of a letter.

When an international application is withdrawn, it loses its effect in the same way as when a national application is withdrawn in a designated country (Article 24(1)(i) of the Convention).

By making effective use of the withdrawal of an international application, it is possible to obtain the results of an international search while preventing the content of the invention from being internationally published. In this case, the international application must be withdrawn within 16 months (17 months if filed with WIPO) from the priority date.

 

Replenishment of missing statements, etc.

Missing parts or elements of the international application that are accepted by the receiving Office may be included in the international application by late filing, even after the international filing date has been granted (Rules 20.3, 20.5).

・Missing parts are parts that are missing or appear to be missing from the description, claims, and drawings of the international application.
- Missing elements are the elements of the international application specified in Article 11(1)(iii)(d) or (e) of the Convention.

If you wish to fill in gaps, you must submit a "Procedure Supplementation Statement" to the receiving Office within two months from the date on which the receiving Office first receives the documents submitted as an international application.

However, please note that the international filing date will be changed to the date of the submission. If delaying the filing date is disadvantageous to the applicant, the applicant may request the receiving Office to ignore the omission (Rule 20.5).

Furthermore, if the receiving Office recognizes that the basic application of the international application claiming priority completely contains the missing parts or missing elements, the missing parts or elements can be supplemented without delaying the international filing date. (Rule 20.6). This is called "citation supplementation."
