INTERNATIONAL APPLICATION AND INTERNATIONAL SEARCH

Article 3
The International Application
(1)
Applications for the protection of inventions in any of the Contracting States may be filed as international applications under this Treaty.
(2)
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.
(3)
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.
(4)
The international application shall:
(i)
be in a prescribed language;
(ii)
comply with the prescribed physical requirements;
(iii)
comply with the prescribed requirement of unity of invention;
(iv)
be subject to the payment of the prescribed fees.

Article 4
The Request
(1)
The request shall contain:
(i)
a petition to the effect that the international application be processed according to this Treaty;
(ii)
the designation of the Contracting State or States in which protection for the invention is desired on the basis of the international application ("designated States"); if for any designated State a regional patent is available and the applicant wishes to obtain a regional patent rather than a national patent, the request shall so indicate; if, under a treaty concerning a regional patent, the applicant cannot limit his application to certain of the States party to that treaty, designation of one of those States and the indication of the wish to obtain the regional patent shall be treated as designation of all the States party to that treaty; if, under the national law of the designated State, the designation of that State has the effect of an application for a regional patent, the designation of the said State shall be treated as an indication of the wish to obtain the regional patent;
(iii)
the name of and other prescribed data concerning the applicant and the agent (if any);
(iv)
the title of the invention;
(v)
the name of and other prescribed data concerning the inventor where the national law of at least one of the designated States requires that these indications be furnished at the time of filing a national application. Otherwise, the said indications may be furnished either in the request or in separate notices addressed to each designated Office 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.
(2)
Every designation shall be subject to the payment of the prescribed fee within the prescribed time limit.
(3)
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.
(4)
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.

Article 5
The Description
The description shall disclose the invention in a manner sufficiently clear and complete for the invention to be carried out by a person skilled in the art.

Article 6
The Claims
The claim or claims shall define the matter for which protection is sought. Claims shall be clear and concise. They shall be fully supported by the description.

Article 7
The Drawings
(1)
Subject to the provisions of paragraph (2)(ii), drawings shall be required when they are necessary for the understanding of the invention.
(2)
Where, without being necessary for the understanding of the invention, the nature of the invention admits of illustration by drawings:
(i)
the applicant may include such drawings in the international application when filed,
(ii)
any designated Office may require that the applicant file such drawings with it within the prescribed time limit.

Article 8

(2) (a) 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.
(b) The international application for which the priority of one or more earlier applications filed in or for a Contracting State is claimed may contain the designation of that State. 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.

Article 9
The Applicant
(1)
Any resident or national of a Contracting State may file an international application.
(2)
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.

Article 15
The International Search
(1)
Each international application shall be the subject of international search.
(2)
The objective of the international search is to discover relevant prior art.
(3)
International search shall be made on the basis of the claims, with due regard to the description and the drawings (if any).
(4)
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.
(5) (a) If the national law of the Contracting State so permits, the applicant who files a national application with 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.
(b) 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.
(c) 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.

Article 16
The International Searching Authority
(1)
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.
(2)
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.
(3) (a) 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.
(b) 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.
(c) 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.
(d) Appointment shall be for a fixed period of time and may be extended for further periods.
(e) 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.

Article 17
Procedure Before the International Searching Authority
(1)
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.
(2) (a) If the International Searching Authority considers
(i)
that the international application relates to a subject matter which the International Searching Authority is not required, under the Regulations, to search, and in the particular case decides not to search, or

that the description, the claims, or the drawings, fail to comply with the prescribed requirements to such an extent that a meaningful search could not be carried out,
the said Authority shall so declare and shall notify the applicant and the International Bureau that no international search report will be established.
(b) 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.
(3) (a) 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.
(b) 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.

Article 18
The International Search Report

Possible Loss of Effect in Designated States
(1)
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:
(i)
if the applicant withdraws his international application or the designation of that State;
(ii)
if the international application is considered withdrawn by virtue of Articles 12(3), 14(1)(b), 14(3)(a), or 14(4), or if the designation of that State is considered withdrawn by virtue of Article 14(3)(b);

(2) (a) 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.
(b) 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).

Article 26
Opportunity to Correct Before Designated Offices
No designated Office shall reject an international application on the grounds of non-compliance with the requirements of this Treaty and the Regulations without first giving the applicant the opportunity to correct the said application to the extent and according to the procedure provided by the national law for the same or comparable situations in respect of national applications.

Article 27
National Requirements
(1)
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.
(2)
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:
(i)
when the applicant is a legal entity, of the name of an officer entitled to represent such legal entity,
(ii)
of documents not part of the international application but which constitute proof of allegations or statements made in that application, including the confirmation of the international application by the signature of the applicant when that application, as filed, was signed by his representative or agent.
(3)
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.
(4)
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.
(5)
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.
(6)
The national law may require that the applicant furnish evidence in respect of any substantive condition of patentability prescribed by such law.
(7)
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.
(8)
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.

Article 28
Amendment of the Claims, the Description, and the Drawings, Before Designated Offices
(1)
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.
(2)
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.
(3)
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.
(4)
Where the designated Office requires a translation of the international application, the amendments shall be in the language of the translation.

Article 29
Effects of the International Publication
(1)
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.
(2)
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:
(i)
a translation into the latter language has been published as provided by the national law, or
(ii)
a translation into the latter language has been made available to the public, by laying open for public inspection as provided by the national law, or
(iii)
a translation into the latter language has been transmitted by the applicant to the actual or prospective unauthorized user of the invention claimed in the international application, or
(iv)
both the acts described in (i) and (iii), or both the acts described in (ii) and (iii), have taken place.
(3)

(1)
International preliminary examination shall be carried out by the International Preliminary Examining Authority.
(2)
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.
(3)
The provisions of Article 16(3) shall apply, mutatis mutandis, in respect of International Preliminary Examining Authorities.

Article 33
The International Preliminary Examination
(1)
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.
(2)
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.
(3)
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.
(4)
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.
(5)
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.
(6)
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.

Article 34
Procedure Before the International Preliminary Examining Authority
(1)
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.
(2) (a) The applicant shall have a right to communicate orally and in writing with the International Preliminary Examining Authority.
(b) 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.
(c) 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:
(i)
the invention satisfies the criteria set forth in Article 33(1),
(ii)
the international application complies with the requirements of this Treaty and the Regulations in so far as checked by that Authority,
(iii)
no observations are intended to be made under Article 35(2), last sentence.
(d) The applicant may respond to the written opinion.
(3) (a) 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.
(b) 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.
(c) 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.
(4) (a) If the International Preliminary Examining Authority considers
(i)
that the international application relates to a subject matter on which the International Preliminary Examining Authority is not required, under the Regulations, to carry out an international preliminary examination, and in the particular case decides not to carry out such examination, or
(ii)
that the description, the claims, or the drawings, are so unclear, or the claims are so inadequately supported by the description, that no meaningful opinion can be formed on the novelty, inventive step (non-obviousness), or industrial applicability, of the claimed invention,
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.
(b) 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.

Article 35
The International Preliminary Examination Report
(1)
The international preliminary examination report shall be established within the prescribed time limit and in the prescribed form.
(2)
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.
(3) (a) 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).
(b) 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).

(b) 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.
