Applications for the protection of inventions in any of the Contracting States may be filed as international applications under this Treaty.

An international application shall contain, as specified in this Treaty and the Regulations, a request, a description, one or more claims, one or more drawings (where required), and an abstract.

The abstract merely serves the purpose of technical information and cannot be taken into account for any other purpose, particularly not for the purpose of interpreting the scope of the protection sought.

The international application shall:

The request shall contain:

Every designation shall be subject to the payment of the prescribed fee within the prescribed time limit.

Unless the applicant asks for any of the other kinds of protection referred to in Article 43, designation shall mean that the desired protection consists of the grant of a patent by or for the designated State. For the purposes of this paragraph, Article 2(ii) shall not apply.

Failure to indicate in the request the name and other prescribed data concerning the inventor shall have no consequence in any designated State whose national law requires the furnishing of the said indications but allows that they be furnished at a time later than that of the filing of a national application. Failure to furnish the said indications in a separate notice shall have no consequence in any designated State whose national law does not require the furnishing of the said indications.

Subject to the provisions of paragraph (2)(ii), drawings shall be required when they are necessary for the understanding of the invention.

Where, without being necessary for the understanding of the invention, the nature of the invention admits of illustration by drawings:

The international application may contain a declaration, as prescribed in the Regulations, claiming the priority of one or more earlier applications filed in or for any country party to the Paris Convention for the Protection of Industrial Property.

Subject to the provisions of subparagraph (b), the conditions for, and the effect of, any priority claim declared under paragraph (1) shall be as provided in Article 4 of the Stockholm Act of the Paris Convention for the Protection of Industrial Property.

Where, in the international application, the priority of one or more national applications filed in or for a designated State is claimed, or where the priority of an international application having designated only one State is claimed, the conditions for, and the effect of, the priority claim in that State shall be governed by the national law of that State.

Any resident or national of a Contracting State may file an international application.

The Assembly may decide to allow the residents and the nationals of any country party to the Paris Convention for the Protection of Industrial Property which is not party to this Treaty to file international applications.

The concepts of residence and nationality, and the application of those concepts in cases where there are several applicants or where the applicants are not the same for all the designated States, are defined in the Regulations.

The receiving Office shall accord as the international filing date the date of receipt of the international application, provided that that Office has found that, at the time of receipt:

If the receiving Office finds that the international application did not, at the time of receipt, fulfil the requirements listed in paragraph (1), it shall, as provided in the Regulations, invite the applicant to file the required correction.

If the applicant complies with the invitation, as provided in the Regulations, the receiving Office shall accord as the international filing date the date of receipt of the required correction.

Subject to article 64(4), any international application fulfilling the requirements listed in items (i) to (iii) of paragraph (1) and accorded an international filing date shall have the effect of a regular national application in each designated State as of the international filing date, which date shall be considered to be the actual filing date in each designated State.

Any international application fulfilling the requirements listed in items (i) to (iii) of paragraph (1) shall be equivalent to a regular national filing within the meaning of the Paris Convention for the Protection of Industrial Property.

One copy of the international application shall be kept by the receiving Office (“home copy”), one copy (“record copy”) shall be transmitted to the International Bureau, and another copy (“search copy”) shall be transmitted to the competent International Searching Authority referred to in Article 16, as provided in the Regulations.

The record copy shall be considered the true copy of the international application.

The international application shall be considered withdrawn if the record copy has not been received by the International Bureau within the prescribed time limit.

Any designated Office may ask the International Bureau to transmit to it a copy of the international application prior to the communication provided for in Article 20, and the International Bureau shall transmit such copy to the designated Office as soon as possible after the expiration of one year from the priority date.

The applicant may, at any time, transmit a copy of his international application to any designated Office.

The applicant may, at any time, ask the International Bureau to transmit a copy of his international application to any designated Office, and the International Bureau shall transmit such copy to the designated Office as soon as possible.

Any national Office may notify the International Bureau that it does not wish to receive copies as provided for in subparagraph (b), in which case that subparagraph shall not be applicable in respect of that Office.

The receiving Office shall check whether the international application contains any of the following defects, that is to say:

If the receiving Office finds any of the said defects, it shall invite the applicant to correct the international application within the prescribed time limit, failing which that application shall be considered withdrawn and the receiving Office shall so declare.

If the international application refers to drawings which, in fact, are not included in that application, the receiving Office shall notify the applicant accordingly and he may furnish them within the prescribed time limit and, if he does, the international filing date shall be the date on which the drawings are received by the receiving Office. Otherwise, any reference to the said drawings shall be considered non-existent.

If the receiving Office finds that, within the prescribed time limits, the fees prescribed under Article 3(4)(iv) have not been paid, or no fee prescribed under Article 4(2) has been paid in respect of any of the designated States, the international application shall be considered withdrawn and the receiving Office shall so declare.

If the receiving Office finds that the fee prescribed under Article 4(2) has been paid in respect of one or more (but less than all) designated States within the prescribed time limit, the designation of those States in respect of which it has not been paid within the prescribed time limit shall be considered withdrawn and the receiving Office shall so declare.

If, after having accorded an international filing date to the international application, the receiving Office finds, within the prescribed time limit, that any of the requirements listed in items (i) to (iii) of Article 11(1) was not complied with at that date, the said application shall be considered withdrawn and the receiving Office shall so declare.

Each international application shall be the subject of international search.

The objective of the international search is to discover relevant prior art.

International search shall be made on the basis of the claims, with due regard to the description and the drawings (if any).

The International Searching Authority referred to in Article 16 shall endeavor to discover as much of the relevant prior art as its facilities permit, and shall, in any case, consult the documentation specified in the Regulations.

If the national law of the Contracting State so permits, the applicant who files a national application within the national Office of or acting for such State may, subject to the conditions provided for in such law, request that a search similar to an international search (“international-type search”) be carried out on such application.

If the national law of the Contracting State so permits, the national Office of or acting for such State may subject any national application filed with it to an international-type search.

The international-type search shall be carried out by the International Searching Authority referred to in Article 16 which would be competent for an international search if the national application were an international application and were filed with the Office referred to in subparagraphs (a) and (b). If the national application is in a language which the International Searching Authority considers it is not equipped to handle, the international-type search shall be carried out on a translation prepared by the applicant in a language prescribed for international applications and which the International Searching Authority has undertaken to accept for international applications. The national application and the translation, when required, shall be presented in the form prescribed for international applications.

International search shall be carried out by an International Searching Authority, which may be either a national Office or an intergovernmental organization, such as the International Patent Institute, whose tasks include the establishing of documentary search reports on prior art with respect to inventions which are the subject of applications.

If, pending the establishment of a single International Searching Authority, there are several International Searching Authorities, each receiving Office shall, in accordance with the provisions of the applicable agreement referred to in paragraph (3)(b), specify the International Searching Authority or Authorities competent for the searching of international applications filed with such Office.

International Searching Authorities shall be appointed by the Assembly. Any national Office and any intergovernmental organization satisfying the requirements referred to in subparagraph (c) may be appointed as International Searching Authority.

Appointment shall be conditional on the consent of the national Office or intergovernmental organization to be appointed and the conclusion of an agreement, subject to approval by the Assembly, between such Office or organization and the International Bureau. The agreement shall specify the rights and obligations of the parties, in particular, the formal undertaking by the said Office or organization to apply and observe all the common rules of international search.

The Regulations prescribe the minimum requirements, particularly as to manpower and documentation, which any Office or organization must satisfy before it can be appointed and must continue to satisfy while it remains appointed.

Appointment shall be for a fixed period of time and may be extended for further periods.

Before the Assembly makes a decision on the appointment of any national Office or intergovernmental organization, or on the extension of its appointment, or before it allows any such appointment to lapse, the Assembly shall hear the interested Office or organization and seek the advice of the Committee for Technical Cooperation referred to in Article 56 once that Committee has been established.

Procedure before the International Searching Authority shall be governed by the provisions of this Treaty, the Regulations, and the agreement which the International Bureau shall conclude, subject to this Treaty and the Regulations, with the said Authority.

If the International Searching Authority considers

the said Authority shall so declare and shall notify the applicant and the International Bureau that no international search report will be established.

If any of the situations referred to in subparagraph (a) is found to exist in connection with certain claims only, the international search report shall so indicate in respect of such claims, whereas, for the other claims, the said report shall be established as provided in Article 18.

If the International Searching Authority considers that the international application does not comply with the requirement of unity of invention as set forth in the Regulations, it shall invite the applicant to pay additional fees. The International Searching Authority shall establish the international search report on those parts of the international application which relate to the invention first mentioned in the claims (“main invention”) and, provided the required additional fees have been paid within the prescribed time limit, on those parts of the international application which relate to inventions in respect of which the said fees were paid.

The national law of any designated State may provide that, where the national Office of that State finds the invitation, referred to in subparagraph (a), of the International Searching Authority justified and where the applicant has not paid all additional fees, those parts of the international application which consequently have not been searched shall, as far as effects in that State are concerned, be considered withdrawn unless a special fee is paid by the applicant to the national Office of that State.

The international search report shall be established within the prescribed time limit and in the prescribed form.

The international search report shall, as soon as it has been established, be transmitted by the International Searching Authority to the applicant and the International Bureau.

The international search report or the declaration referred to in Article 17(2)(a) shall be translated as provided in the Regulations. The translations shall be prepared by or under the responsibility of the International Bureau.

The applicant shall, after having received the international search report, be entitled to one opportunity to amend the claims of the international application by filing amendments with the International Bureau within the prescribed time limit. He may, at the same time, file a brief statement, as provided in the Regulations, explaining the amendments and indicating any impact that such amendments might have on the description and the drawings.

The amendments shall not go beyond the disclosure in the international application as filed.

If the national law of any designated State permits amendments to go beyond the said disclosure, failure to comply with paragraph (2) shall have no consequence in that State.

The international application, together with the international search report (including any indication referred to in Article 17(2)(b)) or the declaration referred to in Article 17(2)(a), shall be communicated to each designated Office, as provided in the Regulations, unless the designated Office waives such requirement in its entirety or in part.

The communication shall include the translation (as prescribed) of the said report or declaration.

If the claims have been amended by virtue of Article 19(1), the communication shall either contain the full text of the claims both as filed and as amended or shall contain the full text of the claims as filed and specify the amendments, and shall include the statement, if any, referred to in Article 19(1).

At the request of the designated Office or the applicant, the International Searching Authority shall send to the said Office or the applicant, respectively, copies of the documents cited in the international search report, as provided in the Regulations.

The International Bureau shall publish international applications.

Subject to the exceptions provided for in subparagraph (b) and in Article 64(3), the international publication of the international application shall be effected promptly after the expiration of 18 months from the priority date of that application.

The applicant may ask the International Bureau to publish his international application any time before the expiration of the time limit referred to in subparagraph (a). The International Bureau shall proceed accordingly, as provided in the Regulations.

The international search report or the declaration referred to in Article 17(2)(a) shall be published as prescribed in the Regulations.

The language and form of the international publication and other details are governed by the Regulations.

There shall be no international publication if the international application is withdrawn or is considered withdrawn before the technical preparations for publication have been completed.

If the international application contains expressions or drawings which, in the opinion of the International Bureau, are contrary to morality or public order, or if, in its opinion, the international application contains disparaging statements as defined in the Regulations, it may omit such expressions, drawings, and statements, from its publications, indicating the place and number of words or drawings omitted, and furnishing, upon request, individual copies of the passages omitted.

The applicant shall furnish a copy of the international application (unless the communication provided for in Article 20 has already taken place) and a translation thereof (as prescribed), and pay the national fee (if any), to each designated Office not later than at the expiration of 20 months from the priority date. Where the national law of the designated State requires the indication of the name of and other prescribed data concerning the inventor but allows that these indications be furnished at a time later than that of the filing of a national application, the applicant shall, unless they were contained in the request, furnish the said indications to the national Office of or acting for the State not later than at the expiration of 20 months from the priority date.

Where the International Searching Authority makes a declaration, under Article 17(2)(a), that no international search report will be established, the time limit for performing the acts referred to in paragraph (1) of this Article shall be the same as that provided for in paragraph (1).

Any national law may, for performing the acts referred to in paragraphs (1) or (2), fix time limits which expire later than the time limit provided for in those paragraphs.

No designated Office shall process or examine the international application prior to the expiration of the applicable time limit under Article 22.

Notwithstanding the provisions of paragraph (1), any designated Office may, on the express request of the applicant, process or examine the international application at any time.

Subject, in case (ii) below, to the provisions of Article 25, the effect of the international application provided for in Article 11(3) shall cease in any designated State with the same consequences as the withdrawal of any national application in that State:

Notwithstanding the provisions of paragraph (1), any designated Office may maintain the effect provided for in Article 11(3) even where such effect is not required to be maintained by virtue of Article 25(2).

Where the receiving Office has refused to accord an international filing date or has declared that the international application is considered withdrawn, or where the International Bureau has made a finding under Article 12(3), the International Bureau shall promptly send, at the request of the applicant, copies of any document in the file to any of the designated Offices named by the applicant.

Where the receiving Office has declared that the designation of any given State is considered withdrawn, the International Bureau shall promptly send, at the request of the applicant, copies of any document in the file to the national Office of such State.

The request under subparagraphs (a) or (b) shall be presented within the prescribed time limit.

Subject to the provisions of subparagraph (b), each designated Office shall, provided that the national fee (if any) has been paid and the appropriate translation (as prescribed) has been furnished within the prescribed time limit, decide whether the refusal, declaration, or finding, referred to in paragraph (1) was justified under the provisions of this Treaty and the Regulations, and, if it finds that the refusal or declaration was the result of an error or omission on the part of the receiving Office or that the finding was the result of an error or omission on the part of the International Bureau, it shall, as far as effects in the State of the designated Office are concerned, treat the international application as if such error or omission had not occurred.

Where the record copy has reached the International Bureau after the expiration of the time limit prescribed under Article 12(3) on account of any error or omission on the part of the applicant, the provisions of subparagraph (a) shall apply only under the circumstances referred to in Article 48(2).

No national law shall require compliance with requirements relating to the form or contents of the international application different from or additional to those which are provided for in this Treaty and the Regulations.

The provisions of paragraph (1) neither affect the application of the provisions of Article 7(2) nor preclude any national law from requiring, once the processing of the international application has started in the designated Office, the furnishing:

Where the applicant, for the purposes of any designated State, is not qualified according to the national law of that State to file a national application because he is not the inventor, the international application may be rejected by the designated Office.

Where the national law provides, in respect of the form or contents of national applications, for requirements which, from the viewpoint of applicants, are more favorable than the requirements provided for by this Treaty and the Regulations in respect of international applications, the national Office, the courts and any other competent organs of or acting for the designated State may apply the former requirements, instead of the latter requirements, to international applications, except where the applicant insists that the requirements provided for by this Treaty and the Regulations be applied to his international application.

Nothing in this Treaty and the Regulations is intended to be construed as prescribing anything that would limit the freedom of each Contracting State to prescribe such substantive conditions of patentability as it desires. In particular, any provision in this Treaty and the Regulations concerning the definition of prior art is exclusively for the purposes of the international procedure and, consequently, any Contracting State is free to apply, when determining the patentability of an invention claimed in an international application, the criteria of its national law in respect of prior art and other conditions of patentability not constituting requirements as to the form and contents of applications.

The national law may require that the applicant furnish evidence in respect of any substantive condition of patentability prescribed by such law.

Any receiving Office or, once the processing of the international application has started in the designated Office, that Office may apply the national law as far as it relates to any requirement that the applicant be represented by an agent having the right to represent applicants before the said Office and/or that the applicant have an address in the designated State for the purpose of receiving notifications.

Nothing in this Treaty and the Regulations is intended to be construed as limiting the freedom of any Contracting State to apply measures deemed necessary for the preservation of its national security or to limit, for the protection of the general economic interests of that State, the right of its own residents or nationals to file international applications.

The applicant shall be given the opportunity to amend the claims, the description, and the drawings, before each designated Office within the prescribed time limit. No designated Office shall grant a patent, or refuse the grant of a patent, before such time limit has expired except with the express consent of the applicant.

The amendments shall not go beyond the disclosure in the international application as filed unless the national law of the designated State permits them to go beyond the said disclosure.

The amendments shall be in accordance with the national law of the designated State in all respects not provided for in this Treaty and the Regulations.

Where the designated Office requires a translation of the international application, the amendments shall be in the language of the translation.

As far as the protection of any rights of the applicant in a designated State is concerned, the effects, in that State, of the international publication of an international application shall, subject to the provisions of paragraphs (2) to (4), be the same as those which the national law of the designated State provides for the compulsory national publication of unexamined national applications as such.

If the language in which the international publication has been effected is different from the language in which publications under the national law are effected in the designated State, the said national law may provide that the effects provided for in paragraph (1) shall be applicable only from such time as:

The national law of any designated State may provide that, where the international publication has been effected, on the request of the applicant, before the expiration of 18 months from the priority date, the effects provided for in paragraph (1) shall be applicable only from the expiration of 18 months from the priority date.

The national law of any designated State may provide that the effects provided for in paragraph (1) shall be applicable only from the date on which a copy of the international application as published under Article 21 has been received in the national Office of or acting for such State. The said Office shall publish the date of receipt in its gazette as soon as possible.

Subject to the provisions of subparagraph (b), the International Bureau and the International Searching Authorities shall not allow access by any person or authority to the international application before the international publication of that application, unless requested or authorized by the applicant.

The provisions of subparagraph (a) shall not apply to any transmittal to the competent International Searching Authority, to transmittals provided for under Article 13, and to communications provided for under Article 20.

No national Office shall allow access to the international application by third parties, unless requested or authorized by the applicant, before the earliest of the following dates:

The provisions of subparagraph (a) shall not prevent any national Office from informing third parties that it has been designated, or from publishing that fact. Such information or publication may, however, contain only the following data: identification of the receiving Office, name of the applicant, international filing date, international application number, and title of the invention.

The provisions of subparagraph (a) shall not prevent any designated Office from allowing access to the international application for the purposes of the judicial authorities.

The provisions of paragraph (2)(a) shall apply to any receiving Office except as far as transmittals provided for under Article 12(1) are concerned.

For the purposes of this Article, the term “access” covers any means by which third parties may acquire cognizance, including individual communication and general publication, provided, however, that no national Office shall generally publish an international application or its translation before the international publication or, if international publication has not taken place by the expiration of 20 months from the priority date, before the expiration of 20 months from the said priority date.

On the demand of the applicant, his international application shall be the subject of an international preliminary examination as provided in the following provisions and the Regulations.

Any applicant who is a resident or national, as defined in the Regulations, of a Contracting State bound by Chapter II, and whose international application has been filed with the receiving Office of or acting for such State, may make a demand for international preliminary examination.

The Assembly may decide to allow persons entitled to file international applications to make a demand for international preliminary examination even if they are residents or nationals of a State not party to this Treaty or not bound by Chapter II.

The demand for international preliminary examination shall be made separately from the international application. The demand shall contain the prescribed particulars and shall be in the prescribed language and form.

The demand shall indicate the Contracting State or States in which the applicant intends to use the results of the international preliminary examination (“elected States”). Additional Contracting States may be elected later. Election may relate only to Contracting States already designated under Article 4.

Applicants referred to in paragraph (2)(a) may elect any Contracting State bound by Chapter II. Applicants referred to in paragraph (2)(b) may elect only such Contracting States bound by Chapter II as have declared that they are prepared to be elected by such applicants.

The demand shall be subject to the payment of the prescribed fees within the prescribed time limit.

The demand shall be submitted to the competent International Preliminary Examining Authority referred to in Article 32.

Any later election shall be submitted to the International Bureau.

Each elected Office shall be notified of its election.

International preliminary examination shall be carried out by the International Preliminary Examining Authority.

In the case of demands referred to in Article 31(2)(a), the receiving Office, and, in the case of demands referred to in Article 31(2)(b), the Assembly, shall, in accordance with the applicable agreement between the interested International Preliminary Examining Authority or Authorities and the International Bureau, specify the International Preliminary Examining Authority or Authorities competent for the preliminary examination.

The provisions of Article 16(3) shall apply, murtatis mutandis, in respect of International Preliminary Examining Authorities.

The objective of the international preliminary examination is to formulate a preliminary and non-binding opinion on the questions whether the claimed invention appears to be novel, to involve an inventive step (to be non-obvious), and to be industrially applicable.

For the purposes of the international preliminary examination, a claimed invention shall be considered novel if it is not anticipated by the prior art as defined in the Regulations.

For the purposes of the international preliminary examination, a claimed invention shall be considered to involve an inventive step if, having regard to the prior art as defined in the Regulations, it is not, at the prescribed relevant date, obvious to a person skilled in the art.

For the purposes of the international preliminary examination, a claimed invention shall be considered industrially applicable if, according to its nature, it can be made or used (in the technological sense) in any kind of industry. “Industry” shall be understood in its broadest sense, as in the Paris Convention for the Protection of Industrial Property.

The criteria described above merely serve the purposes of international preliminary examination. Any Contracting State may apply additional or different criteria for the purpose of deciding whether, in that State, the claimed invention is patentable or not.

The international preliminary examination shall take into consideration all the documents cited in the international search report. It may take into consideration any additional documents considered to be relevant in the particular case.

Procedure before the International Preliminary Examining Authority shall be governed by the provisions of this Treaty, the Regulations, and the agreement which the International Bureau shall conclude, subject to this Treaty and the Regulations, with the said Authority.

The applicant shall have a right to communicate orally and in writing with the International Preliminary Examining Authority.

The applicant shall have a right to amend the claims, the description, and the drawings, in the prescribed manner and within the prescribed time limit, before the international preliminary examination report is established. The amendment shall not go beyond the disclosure in the international application as filed.

The applicant shall receive at least one written opinion from the International Preliminary Examining Authority unless such Authority considers that all of the following conditions are fulfilled:

The applicant may respond to the written opinion.

If the International Preliminary Examining Authority considers that the international application does not comply with the requirement of unity of invention as set forth in the Regulations, it may invite the applicant, at his option, to restrict the claims so as to comply with the requirement or to pay additional fees.

The national law of any elected State may provide that, where the applicant chooses to restrict the claims under subparagraph (a), those parts of the international application which, as a consequence of the restriction, are not to be the subject of international preliminary examination shall, as far as effects in that State are concerned, be considered withdrawn unless a special fee is paid by the applicant to the national Office of that State.

If the applicant does not comply with the invitation referred to in subparagraph (a) within the prescribed time limit, the International Preliminary Examining Authority shall establish an international preliminary examination report on those parts of the international application which relate to what appears to be the main invention and shall indicate the relevant facts in the said report. The national law of any elected State may provide that, where its national Office finds the invitation of the International Preliminary Examining Authority justified, those parts of the international application which do not relate to the main invention shall, as far as effects in that State are concerned, be considered withdrawn unless a special fee is paid by the applicant to that Office.

If the International Preliminary Examining Authority considers—

the said Authority shall not go into the questions referred to in Article 33(1) and shall inform the applicant of this opinion and the reasons therefor.

If any of the situations referred to in subparagraph (a) is found to exist in, or in connection with, certain claims only, the provisions of that subparagraph shall apply only to the said claims.

The international preliminary examination report shall be established within the prescribed time limit and in the prescribed form.

The international preliminary examination report shall not contain any statement on the question whether the claimed invention is or seems to be patentable or unpatentable according to any national law. It shall state, subject to the provisions of paragraph (3), in relation to each claim, whether the claim appears to satisfy the criteria of novelty, inventive step (non-obviousness), and industrial applicability, as defined for the purposes of the international preliminary examination in Article 33(1) to (4). The statement shall be accompanied by the citation of the documents believed to support the stated conclusion with such explanations as the circumstances of the case may require. The statement shall also be accompanied by such other observations as the Regulations provide for.

If, at the time of establishing the international preliminary examination report, the International Preliminary Examining Authority considers that any of the situations referred to in Article 34(4)(a) exists, that report shall state this opinion and the reasons therefor. It shall not contain any statement as provided in paragraph (2).

If a situation under Article 34(4)(b) is found to exist, the international preliminary examination report shall, in relation to the claims in question, contain the statement as provided in subparagraph (a), whereas, in relation to the other claims, it shall contain the statement as provided in paragraph (2).

The international preliminary examination report, together with the prescribed annexes, shall be transmitted to the applicant and to the International Bureau.

The international preliminary examination report and its annexes shall be translated into the prescribed languages.

Any translation of the said report shall be prepared by or under the responsibility of the International Bureau, whereas any translation of the said annexes shall be prepared by the applicant.

The international preliminary examination report, together with its translation (as prescribed) and its annexes (in the original language), shall be communicated by the International Bureau to each elected Office.

The prescribed translation of the annexes shall be transmitted within the prescribed time limit by the applicant to the elected Offices.

The provisions of Article 20(3) shall apply, mutatis mutandis, to copies of any document which is cited in the international preliminary examination report and which was not cited in the international search report.

The applicant may withdraw any or all elections.

If the election of all elected States is withdrawn, the demand shall be considered withdrawn.

Any withdrawal shall be notified to the International Bureau.

The elected Offices concerned and the International Preliminary Examining Authority concerned shall be notified accordingly by the International Bureau.

Subject to the provisions of subparagraph (b), withdrawal of the demand or of the election of a Contracting State shall, unless the national law of that State provides otherwise, be considered to be withdrawal of the international application as far as that State is concerned.

Withdrawal of the demand or of the election shall not be considered to be withdrawal of the international application if such withdrawal is effected prior to the expiration of the applicable time limit under Article 22; however, any Contracting State may provide in its national law that the aforesaid shall apply only if its national Office has received, within the said time limit, a copy of the international application, together with a translation (as prescribed), and the national fee.

Neither the International Bureau nor the International Preliminary Examining Authority shall, unless requested or authorized by the applicant, allow access within the meaning, and with the proviso, of Article 30(4) to the file of the international preliminary examination by any person or authority at any time, except by the elected Offices once the international preliminary examination report has been established.

Subject to the provisions of paragraph (1) and Articles 36(1) and (3) and 37(3)(b), neither the International Bureau nor the International Preliminary Examining Authority shall, unless requested or authorized by the applicant, give information on the issuance or non-issuance of an international preliminary examination report and on the withdrawal or nonwithdrawal of the demand or of any election.

If the election of any Contracting State has been effected prior to the expiration of the 19th month from the priority date, the provisions of Article 22 shall not apply to such State and the applicant shall furnish a copy of the international application (unless the communication under Article 20 has already taken place) and a translation thereof (as prescribed), and pay the national fee (if any), to each elected Office not later than at the expiration of 30 months from the priority date.

Any national law may, for performing the acts referred to in subparagraph (a), fix time limits which expire later than the time limit provided for in that subparagraph.

The effect provided for in Article 11(3) shall cease in the elected State with the same consequences as the withdrawal of any national application in that State if the applicant fails to perform the acts referred to in paragraph (1)(a) within the time limit applicable under paragraph (1)(a) or (b).

Any elected Office may maintain the effect provided for in Article 11(3) even where the applicant does not comply with the requirements provided for in paragraph (1)(a) or (b).

Notwithstanding the provisions of paragraph (1), any elected Office may, on the express request of the applicant, proceed to the examination and other processing of the international application at any time.

The applicant shall be given the opportunity to amend the claims, the description, and the drawings, before each elected Office within the prescribed time limit. No elected Office shall grant a patent, or refuse the grant of a patent, before such time limit has expired, except with the express consent of the applicant.

The amendments shall not go beyond the disclosure in the international application as filed, unless the national law of the elected State permits them to go beyond the said disclosure.

The amendments shall be in accordance with the national law of the elected State in all respects not provided for in this Treaty and the Regulations.

Where an elected Office requires a translation of the international application, the amendments shall be in the language of the translation.

Any treaty providing for the grant of regional patents (“regional patent treaty”), and giving to all persons who, according to Article 9, are entitled to file international applications the right to file applications for such patents, may provide that international applications designating or electing a State party to both the regional patent treaty and the present Treaty may be filed as applications for such patents.

The national law of the said designated or elected State may provide that any designation or election of such State in the international application shall have the effect of an indication of the wish to obtain a regional patent under the regional patent treaty.

The details for computing time limits referred to in this Treaty are governed by the Regulations.

All time limits fixed in Chapters I and II of this Treaty may, outside any revision under Article 60, be modified by a decision of the Contracting States.

the priority claim shall, for the purposes of the procedure under the Treaty, be considered not to have been made. However, where, resulting from an obvious error, the indication of the said country or the said date is missing or is erroneous, the receiving Office may, at the request of the applicant, make the necessary correction. The error shall be considered as an obvious error whenever the correction is obvious from a comparison with the earlier application. Where the error consists of the omission of the indication of the said date, the correction can only be made before the transmittal of the record copy to the International Bureau. In the case of any other error relating to the indication of the said date or in the case of any error relating to the indication of the said country, the correction can only be made before the expiration of the time limit under Rule 17.1(a) computed on the basis of the correct priority date.

If the applicant fails to act accordingly within one month from the date of the invitation, the declaration made under Article 8(1) shall be cancelled ex officio.

Where the priorities of several earlier applications are claimed, the provisions of paragraphs (a) to (d) shall apply to each of them.

Where two or more applicants file an international application which designates a State whose national law requires that national applications be filed by the inventor and where an applicant for that designated State who is an inventor refused to sign the request or could not be found or reached after diligent effort, the request need not be signed by that applicant if it is signed by at least one applicant and a statement is furnished explaining, to the satisfaction of the receiving Office, the lack of the signature concerned.

Where any name or address is written in characters other than those of the Latin alphabet, the same shall also be indicated in characters of the Latin alphabet either as a mere transliteration or through translation into English. The applicant shall decide which words will be merely transliterated and which words will be so translated.

The name of any country written in characters other than those of the Latin alphabet shall also be indicated in English.

The request shall contain no matter other than that specified in Rules 4.1 to 4.16, provided that the Administrative Instructions may permit, but cannot make mandatory, the inclusion in the request of any additional matter specified in the Administrative Instructions.

The description shall first state the title of the invention as appearing in the request and shall:

The manner and order specified in paragraph (a) shall be followed except when, because of the nature of the invention, a different manner or a different order would result in a better understanding and a more economic presentation.

Subject to the provisions of paragraph (b), each of the parts referred to in paragraph (a) shall preferably be preceded by an appropriate heading as suggested in the Administrative Instructions.

The number of the claims shall be reasonable in consideration of the nature of the invention claimed.

If there are several claims, they shall be numbered consecutively in Arabic numerals.

The method of numbering in the case of the amendment of claims shall be governed by the Administrative Instructions.

Claims shall not, except where absolutely necessary, rely, in respect of the technical features of the invention, on references to the description or drawings. In particular, they shall not rely on such references as: “as described in part … of the description,” or “as illustrated in figure … of the drawings.”

Where the international application contains drawings, the technical features mentioned in the claims shall preferably be followed by the reference signs relating to such features. When used, the reference signs shall preferably be placed between parentheses. If inclusion of reference signs does not particularly facilitate quicker understanding of a claim, it should not be made. Reference signs may be removed by a designated Office for the purposes of publication by such Office.

The definition of the matter for which protection is sought shall be in terms of the technical features of the invention.

Whenever appropriate, claims shall contain:

Where the national law of the designated State does not require the manner of claiming provided for in paragraph (b), failure to use that manner of claiming shall have no effect in that State provided the manner of claiming actually used satisfies the national law of that State.

Any claim which includes all the features of one or more other claims (claim in dependent form, hereinafter referred to as “dependent claim”) shall do so by a reference, if possible at the beginning, to the other claim or claims and shall then state the additional features claimed. Any dependent claim which refers to more than one other claim (“multiple dependent claim”) shall refer to such claims in the alternative only. Multiple dependent claims shall not serve as a basis for any other multiple dependent claim. Where the national law of the national Office acting as International Searching Authority does not allow multiple dependent claims to be drafted in a manner different from that provided for in the preceding two sentences, failure to use that manner of claiming may result in an indication under Article 17(2)(b) in the international search report. Failure to use the said manner of claiming shall have no effect in a designated State if the manner of claiming actually used satisfies the national law of that State.

Any dependent claim shall be construed as including all the limitations contained in the claim to which it refers or, if the dependent claim is a multiple dependent claim, all the limitations contained in the particular claim in relation to which it is considered.

All dependent claims referring back to a single previous claim, and all dependent claims referring back to several previous claims, shall be grouped together to the extent and in the most practical way possible.

The abstract shall consist of the following:

The abstract shall be as concise as the disclosure permits (preferably 50 to 150 words if it is in English or when translated into English).

The abstract shall not contain statements on the alleged merits or value of the claimed invention or on its speculative application.

Each main technical feature mentioned in the abstract and illustrated by a drawing in the international application shall be followed by a reference sign, placed between parentheses.

If the applicant fails to make the indication referred to in Rule 3.3(a)(iii), or if the International Searching Authority finds that a figure or figures other than that figure or those figures suggested by the applicant would, among all the figures of all the drawings, better characterize the invention, it shall, subject to paragraph (b), indicate the figure or figures which should accompany the abstract when the latter is published by the International Bureau. In such case, the abstract shall be accompanied by the figure or figures so indicated by the International Searching Authority. Otherwise, the abstract shall, subject to paragraph (b), be accompanied by the figure or figures suggested by the applicant.

If the International Searching Authority finds that none of the figures of the drawings is useful for the understanding of the abstract, it shall notify the International Bureau accordingly. In such case, the abstract, when published by the International Bureau, shall not be accompanied by any figure of the drawings even where the applicant has made a suggestion under Rule 3.3(a)(iii).

expressions or drawings contrary to morality;

expressions or drawings contrary to public order;

statements disparaging the products or processes of any particular person other than the applicant, or the merits or validity of applications or patents of any such person (mere comparisons with the prior art shall not be considered disparaging per se);

any statement or other matter obviously irrelevant or unnecessary under the circumstances.

Units of weights and measures shall be expressed in terms of the metric system, or also expressed in such terms if first expressed in terms of a different system.

Temperatures shall be expressed in degrees Celsius, or also expressed in degrees Celsius, if first expressed in a different manner.

[Deleted]

For indications of heat, energy, light, sound, and magnetism, as well as for mathematical formulae and electrical units, the rules of international practice shall be observed; for chemical formulae, the symbols, atomic weights, and molecular formulae, in general use, shall be employed.

In general, only such technical terms, signs and symbols should be used as are generally accepted in the art.

When the international application or its translation is in English or Japanese, the beginning of any decimal fraction shall be marked by a period, whereas, when the international application or its translation is in a language other than English or Japanese, it shall be marked by a comma.

Subject to the provisions of paragraph (b), the international application and each of the documents referred to in the check list (Rule 3.3(a)(ii)) shall be filed in one copy.

Any receiving Office may require that the international application and any of the documents referred to in the check list (Rule 3.3(a)(ii)), except the receipt for the fees paid or the check for the payment of the fees, be filed in two or three copies. In that case, the receiving Office shall be responsible for verifying the identity of the second and the third copies with the record copy.

All elements of the international application (i.e., the request, the description, the claims, the drawings, and the abstract) shall be so presented as to admit of direct reproduction by photography, electrostatic processes, photo offset, and microfilming, in any number of copies.

All sheets shall be free from creases and cracks; they shall not be folded.

Only one side of each sheet shall be used.

Subject to Rule 11.10(d) and Rule 11.13(j), each sheet shall be used in an upright position (i.e., the short sides at the top and bottom).

Each element (request, description, claims, drawings, abstract) of the international application shall commence on a new sheet.

All sheets of the international application shall be so connected that they can be easily turned when consulted, and easily separated and joined again if they have been separated for reproduction purposes.

The minimum margins of the sheets containing the description, the claims, and the abstract, shall be as follows:

• –

  top: 2 cm

• –

  left side: 2.5 cm

• –

  right side: 2 cm

• –

  bottom: 2 cm

The recommended maximum, for the margins provided for in paragraph (a), is as follows:

• –

  top: 4 cm

• –

  left side: 4 cm

• –

  right side: 3 cm

• –

  bottom: 3 cm

On sheets containing drawings, the surface usable shall not exceed 26.2 cm × 17.0 cm. The sheets shall not contain frames around the usable or used surface. The minimum margins shall be as follows:

• –

  top: 2.5 cm

• –

  left side: 2.5 cm

• –

  right side: 1.5 cm

• –

  bottom: 1.0 cm

The margins referred to in paragraphs (a) to (c) apply to A4-size sheets, so that, even if the receiving Office accepts other sizes, the A4-size record copy and, when so required, the A4-size search copy shall leave the aforesaid margins.

Subject to paragraph (f) and to Rule 11.8(b), the margins of the international application, when submitted, must be completely blank.

The top margin may contain in the left-hand comer an indication of the applicant’s file reference, provided that the reference appears within 1.5 cm from the top of the sheet. The number of characters in the applicant’s file reference shall not exceed the maximum fixed by the Administrative Instructions.

All the sheets contained in the international application shall be numbered in consecutive Arabic numerals.

The numbers shall be centred at the top or bottom of the sheet, but shall not be placed in the margin.

It is strongly recommended to number every fifth line of each sheet of the description, and of each sheet of claims.

The numbers should appear in the right half of the left margin.

The request, the description, the claims and the abstract shall be typed or printed.

Only graphic symbols and characters, chemical or mathematical formulae, and certain characters in the Japanese language may, when necessary, be written by hand or drawn.

The typing shall be 1½-spaced.

All text matter shall be in characters the capital letters of which are not less than 0.21 cm high, and shall be in a dark, indelible color, satisfying the requirements specified in Rule 11.2.

As far as the spacing of the typing and the size of the characters are concerned, paragraphs (c) and (d) shall not apply to texts in the Japanese language.

The request, the description, the claims and the abstract shall not contain drawings.

The description, the claims and the abstract may contain chemical or mathematical formulae.

The description and the abstract may contain tables; any claim may contain tables only if the subject matter of the claim makes the use of tables desirable.

Tables and chemical or mathematical formulae may be placed sideways on the sheet if they cannot be presented satisfactorily in an upright position thereon; sheets on which tables or chemical or mathematical formulae are presented sideways shall be so presented that the tops of the tables or formulae are at the left side of the sheet.

The drawings shall not contain text matter, except a single word or words, when absolutely indispensable, such as “water,” “steam,” “open,” “closed,” “section on AB,” and, in the case of electric circuits and block schematic or flow sheet diagrams, a few short catchwords indispensable for understanding.

Any words used shall be so placed that, if translated, they may be pasted over without interfering with any lines of the drawings.

Drawings shall be executed in durable, black, sufficiently dense and dark, uniformly thick and well-defined, lines and strokes without colorings.

Cross-sections shall be indicated by oblique hatching which should not impede the clear reading of the reference signs and leading lines.

The scale of the drawings and the distinctness of their graphical execution shall be such that a photographic reproduction with a linear reduction in size to two-thirds would enable all details to be distinguished without difficulty.

When, in exceptional cases, the scale is given on a drawing, it shall be represented graphically.

All numbers, letters and reference lines, appearing on the drawings, shall be simple and clear. Brackets, circles or inverted commas shall not be used in association with numbers and letters.

All lines in the drawings shall, ordinarily, be drawn with the aid of drafting instruments.

Each element of each figure shall be in proper proportion to each of the other elements in the figure, except where the use of a different proportion is indispensable for the clarity of the figure.

The height of the numbers and letters shall not be less than 0.32 cm. For the lettering of drawings, the Latin and, where customary, the Greek alphabets shall be used.

The same sheet of drawings may contain several figures. Where figures on two or more sheets form in effect a single complete figure, the figures on the several sheets shall be so arranged that the complete figure can be assembled without concealing any part of any of the figures appearing on the various sheets.

The different figures shall be arranged on a sheet or sheets without wasting space, preferably in an upright position, clearly separated from one another. Where the figures are not arranged in an upright position, they shall be presented sideways with the top of the figures at the left side of the sheet.

The different figures shall be numbered in arabic numerals consecutively and independently of the numbering of the sheets.

Reference signs not mentioned in the description shall not appear in the drawings, and vice versa.

The same features, when denoted by reference signs, shall, throughout the international application, be denoted by the same signs.

If the drawings contain a large number of reference signs, it is strongly recommended to attach a separate sheet listing all reference signs and the features denoted by them.

Any international application shall be filed in the language, or one of the languages, specified in the agreement concluded between the International Bureau and the International Searching Authority competent for the international searching of that application, provided that, if the agreement specifies several languages, the receiving Office may prescribe among the specified languages that language in which or those languages in one of which the international application must be filed.

Notwithstanding paragraph (a), the request, any text matter of the drawings, and the abstract need not be in the same language as other elements of the international application, provided that:

Subject to paragraph (d), where the official language of the receiving Office is one of the languages referred to in Rule 48.3(a) but is a language not specified in the agreement referred to in paragraph (a), the international application may be filed in the said official language. If the international application is filed in the said official language, the search copy transmitted to the International Searching Authority under Rule 23.1 shall be accompanied by a translation into the language, or one of the languages, specified in the agreement referred to in paragraph (a); such translation shall be prepared under the responsibility of the receiving Office.

Paragraph (c) shall apply only where the International Searching Authority has declared, in a notification addressed to the International Bureau, that it accepts to search international applications on the basis of the translation referred to in paragraph (c).

A reference to a deposited microorganism shall indicate,

Failure to include a reference to a deposited microorganism or failure to include, in a reference to a deposited microorganism, an indication in accordance with paragraph (a), shall have no consequence in any designated State whose national law does not require such reference or such indication in a national application.

A reference to a deposited microorganism shall be considered to be made for the purposes of all designated States, unless it is expressly made for the purposes of certain of the designated States only; the same applies to the indications included in the reference.

References to different deposits of the microorganism may be made for different designated States.

Any designated Office shall be entitled to disregard a deposit made with a depositary institution other than one notified by it under Rule 13bis.7(b).

Where the international application contains a reference to a deposited microorganism, the applicant shall, upon the request of the International Searching Authority or the International Preliminary Examining Authority, authorize and assure the furnishing of a sample of that microorganism by the depositary institution to the said Authority, provided that the said Authority has notified the International Bureau that it may require the furnishing of samples and that such samples will be used solely for the purposes of international search or international preliminary examination, as the case may be, and such notification has been published in the Gazette.

Pursuant to Articles 23 and 40, no furnishing of samples of the deposited microorganism to which a reference is made in an international application shall, except with the authorization of the applicant, take place before the expiration of the applicable time limits after which national processing may start under the said Articles. However, where the applicant performs the acts referred to in Articles 22 or 39 after international publication but before the expiration of the said time limits, the furnishing of samples of the deposited microorganism may take place, once the said acts have been performed. Notwithstanding the previous provision, the furnishing of samples of the deposited microorganism may take place under the national law applicable for any designated Office as soon as, under that law, the international publication has the effects of the compulsory national publication of an unexamined national application.

Any national Office may notify the International Bureau of any requirement of the national law,

Each national Office shall notify the International Bureau of the depositary institutions with which the national law permits deposits of microorganisms to be made for the purposes of patent procedure before that Office or, if the national law does not provide for or permit such deposits, of that fact.

The International Bureau shall promptly publish in the Gazette requirements notified to it under paragraph (a) and information notified to it under paragraph (b).

If the International Searching Authority finds that a nucleotide and/or amino acid sequence listing does not comply with the standard prescribed in the Administrative Instructions under Rule 5.2, and/or is not in a machine readable form provided for in those Instructions, it may invite the applicant, within a time limit fixed in the invitation, as the case may be:

Any sequence listing furnished under paragraph (a) shall be accompanied by a statement to the effect that the listing does not include matter which goes beyond the disclosure in the international application as filed.

If the applicant does not comply with the invitation within the time limit fixed in the invitation, the International Searching Authority shall not be required to search the international application to the extent that such non-compliance has the result that a meaningful search cannot be carried out.

If the International Searching Authority chooses, under paragraph (a)(ii), to transcribe the sequence listing into a machine readable form, it shall send a copy of such transcription in machine readable form to the applicant.

The International Searching Authority shall, upon request, make available to the International Preliminary Examining Authority a copy of any sequence listing furnished to it, or as transcribed by it, under paragraph (a).

A sequence listing furnished to the International Searching Authority, or as transcribed by it, under paragraph (a) shall not form part of the international application.
