addition; or
(ii) the applicant intends to make an indication under Rule 49bis.1(d) of
the wish that the international application be treated, in any
designated State, as an application for a continuation or a
continuation-in-part of an earlier application;
the request shall so indicate and shall indicate the relevant parent application or
parent patent or other parent grant.
(b) The inclusion in the request of an indication under paragraph (a) shall
have no effect on the operation of Rule 4.9.

Article 11(1)(iii)(d) or (e) or a part of the description, claims or drawings
referred to in Rule 20.5(a) is not otherwise contained in the international
application but is completely contained in the earlier application, that element or
part is, subject to confirmation under Rule 20.6, incorporated by reference in the
international application for the purposes of Rule 20.6. Such a statement, if not
contained in the request on that date, may be added to the request if, and only if,
it was otherwise contained in, or submitted with, the international application on
that date.
4.19 Additional Matter
(a) The request shall contain no matter other than that specified in Rules 4.1
to 4.18, provided that the Administrative Instructions may permit, but cannot

to 4.18 or permitted under paragraph (a) by the Administrative Instructions, the
receiving Office shall ex officio delete the additional matter.
Rule 5
The Description
5.1 Manner of the Description
(a) The description shall first state the title of the invention as appearing in
the request and shall:
(i) specify the technical field to which the invention relates;
(ii) indicate the background art which, as far as known to the applicant,
can be regarded as useful for the understanding, searching and examination of
the invention, and, preferably, cite the documents reflecting such art;

28

Regulations under the PCT (as in force from January 1, 2013)

(iii) disclose the invention, as claimed, in such terms that the technical
problem (even if not expressly stated as such) and its solution can be
understood, and state the advantageous effects, if any, of the invention with
reference to the background art;
(iv) briefly describe the figures in the drawings, if any;
(v) set forth at least the best mode contemplated by the applicant for
carrying out the invention claimed; this shall be done in terms of examples,
where appropriate, and with reference to the drawings, if any; where the
national law of the designated State does not require the description of the best
mode but is satisfied with the description of any mode (whether it is the best
contemplated or not), failure to describe the best mode contemplated shall have
no effect in that State;
(vi) indicate explicitly, when it is not obvious from the description or
nature of the invention, the way in which the invention is capable of exploitation
in industry and the way in which it can be made and used, or, if it can only be
used, the way in which it can be used; the term “industry” is to be understood in
its broadest sense as in the Paris Convention for the Protection of Industrial
Property.
(b) 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.
(c) 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.
5.2 Nucleotide and/or Amino Acid Sequence Disclosure
(a) Where the international application contains disclosure of one or more
nucleotide and/or amino acid sequences, the description shall contain a sequence
listing complying with the standard provided for in the Administrative
Instructions and presented as a separate part of the description in accordance
with that standard.
(b) Where the sequence listing part of the description contains any free text
as defined in the standard provided for in the Administrative Instructions, that
free text shall also appear in the main part of the description in the language
thereof.

29

Regulations under the PCT (as in force from January 1, 2013)

Rule 6
The Claims
6.1 Number and Numbering of Claims
(a) The number of the claims shall be reasonable in consideration of the
nature of the invention claimed.
(b) If there are several claims, they shall be numbered consecutively in
Arabic numerals.
(c) The method of numbering in the case of the amendment of claims shall
be governed by the Administrative Instructions.
6.2 References to Other Parts of the International Application
(a) 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.”
(b) 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.
6.3 Manner of Claiming
(a) The definition of the matter for which protection is sought shall be in
terms of the technical features of the invention.
(b) Whenever appropriate, claims shall contain:
(i) a statement indicating those technical features of the invention which
are necessary for the definition of the claimed subject matter but which, in
combination, are part of the prior art,
(ii) a characterizing portion – preceded by the words “characterized in
that,” “characterized by,” “wherein the improvement comprises,” or any other
words to the same effect – stating concisely the technical features which, in
combination with the features stated under (i), it is desired to protect.
(c) 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.

30

Regulations under the PCT (as in force from January 1, 2013)

6.4 Dependent Claims
(a) 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.
(b) 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.
(c) 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.
6.5 Utility Models
Any designated State in which the grant of a utility model is sought on the
basis of an international application may, instead of Rules 6.1 to 6.4, apply in
respect of the matters regulated in those Rules the provisions of its national law
concerning utility models once the processing of the international application
has started in that State, provided that the applicant shall be allowed at least two
months from the expiration of the time limit applicable under Article 22 to adapt
his application to the requirements of the said provisions of the national law.
Rule 7
The Drawings
7.1 Flow Sheets and Diagrams
Flow sheets and diagrams are considered drawings.
7.2 Time Limit
The time limit referred to in Article 7(2)(ii) shall be reasonable under the
circumstances of the case and shall, in no case, be shorter than two months from

31

Regulations under the PCT (as in force from January 1, 2013)

the date of the written invitation requiring the filing of drawings or additional
drawings under the said provision.
Rule 8
The Abstract
8.1 Contents and Form of the Abstract
(a) The abstract shall consist of the following:
(i) a summary of the disclosure as contained in the description, the
claims, and any drawings; the summary shall indicate the technical field to
which the invention pertains and shall be drafted in a way which allows the clear
understanding of the technical problem, the gist of the solution of that problem
through the invention, and the principal use or uses of the invention;
(ii) where applicable, the chemical formula which, among all the
formulae contained in the international application, best characterizes the
invention.
(b) 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).
(c) The abstract shall not contain statements on the alleged merits or value
of the claimed invention or on its speculative application.
(d) 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.
8.2 Figure
(a) 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.
(b) 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).

32

Regulations under the PCT (as in force from January 1, 2013)

8.3 Guiding Principles in Drafting
The abstract shall be so drafted that it can efficiently serve as a scanning tool
for purposes of searching in the particular art, especially by assisting the
scientist, engineer or researcher in formulating an opinion on whether there is a
need for consulting the international application itself.
Rule 9
Expressions, Etc., Not to Be Used
9.1 Definition
The international application shall not contain:
(i) expressions or drawings contrary to morality;
(ii) expressions or drawings contrary to public order;
(iii) 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);
(iv) any statement or other matter obviously irrelevant or unnecessary
under the circumstances.
9.2 Noting of Lack of Compliance
The receiving Office and the International Searching Authority may note
lack of compliance with the prescriptions of Rule 9.1 and may suggest to the
applicant that he voluntarily correct his international application accordingly. If

filing date of any application whose priority is claimed, the receiving Office
shall call that circumstance to the attention of the applicant.

applicant furnishes to the receiving Office, on or before the date on which all of

promptly published by the International Bureau in the Gazette. 3
(a-bis) Where a missing element or part cannot be incorporated by reference

copy is transmitted to the International Bureau unless no search fee has been
paid. In the latter case, it shall be transmitted promptly after payment of the
search fee.
(b) Where a translation of the international application is furnished under
Rule 12.3, a copy of that translation and of the request, which together shall be

receiving Office to the International Searching Authority, unless no search fee

64

Regulations under the PCT (as in force from January 1, 2013)

Regulations under the PCT (as in force from January 1, 2013)

26.4 Procedure
A correction of the request offered to the receiving Office may be stated in a
letter addressed to that Office if the correction is of such a nature that it can be
transferred from the letter to the request without adversely affecting the clarity
and the direct reproducibility of the sheet on to which the correction is to be
transferred; otherwise, and in the case of a correction of any element of the
international application other than the request, the applicant shall be required to
submit a replacement sheet embodying the correction and the letter
accompanying the replacement sheet shall draw attention to the differences
between the replaced sheet and the replacement sheet.
26.5 Decision of the Receiving Office
The receiving Office shall decide whether the applicant has submitted the
correction within the applicable time limit under Rule 26.2, and, if the correction
has been submitted within that time limit, whether the international application
so corrected is or is not to be considered withdrawn, provided that no
international application shall be considered withdrawn for lack of compliance
with the physical requirements referred to in Rule 11 if it complies with those
requirements to the extent necessary for the purpose of reasonably uniform
international publication.
Rule 26bis
Correction or Addition of Priority Claim
26bis.1 Correction or Addition of Priority Claim
(a) The applicant may correct a priority claim or add a priority claim to the
request by a notice submitted to the receiving Office or the International Bureau
within a time limit of 16 months from the priority date or, where the correction
or addition would cause a change in the priority date, 16 months from the
priority date as so changed, whichever 16-month period expires first, provided
that such a notice may be submitted until the expiration of four months from the
international filing date. The correction of a priority claim may include the
addition of any indication referred to in Rule 4.10.
(b) Any notice referred to in paragraph (a) received by the receiving Office
or the International Bureau after the applicant has made a request for early
publication under Article 21(2)(b) shall be considered not to have been
submitted, unless that request is withdrawn before the technical preparations for
international publication have been completed.
(c) Where the correction or addition of a priority claim causes a change in
the priority date, any time limit which is computed from the previously

68

Regulations under the PCT (as in force from January 1, 2013)

applicable priority date and which has not already expired shall be computed
from the priority date as so changed.
26bis.2 Defects in Priority Claims
(a) Where the receiving Office or, if the receiving Office fails to do so, the
International Bureau, finds in relation to a priority claim:
(i) that the international application has an international filing date which
is later than the date on which the priority period expired and that a
request for restoration of the right of priority under Rule 26bis.3 has
not been submitted;
(ii) that the priority claim does not comply with the requirements of
Rule 4.10; or
(iii) that any indication in the priority claim is inconsistent with the
corresponding indication appearing in the priority document;
the receiving Office or the International Bureau, as the case may be, shall invite
the applicant to correct the priority claim. In the case referred to in item (i),
where the international filing date is within two months from the date on which
the priority period expired, the receiving Office or the International Bureau, as
the case may be, shall also notify the applicant of the possibility of submitting a
request for the restoration of the right of priority in accordance with
Rule 26bis.3, unless the receiving Office has notified the International Bureau
under Rule 26bis.3(j) of the incompatibility of Rule 26bis.3(a) to (i) with the
national law applied by that Office.
(b) If the applicant does not, before the expiration of the time limit under
Rule 26bis.1(a), submit a notice correcting the priority claim, that priority claim
shall, subject to paragraph (c), for the purposes of the procedure under the
Treaty, be considered not to have been made (“considered void”) and the
receiving Office or the International Bureau, as the case may be, shall so declare
and shall inform the applicant accordingly. Any notice correcting the priority
claim which is received before the receiving Office or the International Bureau,
as the case may be, so declares and not later than one month after the expiration
of that time limit shall be considered to have been received before the expiration
of that time limit.
(c) A priority claim shall not be considered void only because:
(i) the indication of the number of the earlier application referred to in
Rule 4.10(a)(ii) is missing;
(ii) an indication in the priority claim is inconsistent with the
corresponding indication appearing in the priority document; or

69

Regulations under the PCT (as in force from January 1, 2013)

(iii) the international application has an international filing date which is
later than the date on which the priority period expired, provided that the
international filing date is within the period of two months from that date.
(d) Where the receiving Office or the International Bureau has made a
declaration under paragraph (b) or where the priority claim has not been
considered void only because paragraph (c) applies, the International Bureau
shall publish, together with the international application, information concerning
the priority claim as prescribed by the Administrative Instructions, as well as
any information submitted by the applicant concerning such priority claim
which is received by the International Bureau prior to the completion of the
technical preparations for international publication. Such information shall be
included in the communication under Article 20 where the international
application is not published by virtue of Article 64(3).
(e) Where the applicant wishes to correct or add a priority claim but the
time limit under Rule 26bis.1 has expired, the applicant may, prior to the
expiration of 30 months from the priority date and subject to the payment of a
special fee whose amount shall be fixed in the Administrative Instructions,
request the International Bureau to publish information concerning the matter,
and the International Bureau shall promptly publish such information.
26bis.3 Restoration of Right of Priority by Receiving Office
(a) Where the international application has an international filing date
which is later than the date on which the priority period expired but within the
period of two months from that date, the receiving Office shall, on the request of
the applicant, and subject to paragraphs (b) to (g) of this Rule, restore the right
of priority if the Office finds that a criterion applied by it (“criterion for
restoration”) is satisfied, namely, that the failure to file the international
application within the priority period:
(i) occurred in spite of due care required by the circumstances having
been taken; or
(ii) was unintentional.
Each receiving Office shall apply at least one of those criteria and may apply
both of them.
(b) A request under paragraph (a) shall:
(i) be filed with the receiving Office within the time limit applicable
under paragraph (e);
(ii) state the reasons for the failure to file the international application
within the priority period; and

70

Regulations under the PCT (as in force from January 1, 2013)

(iii) preferably be accompanied by any declaration or other evidence
required under paragraph (f).
(c) Where a priority claim in respect of the earlier application is not
contained in the international application, the applicant shall submit, within the
time limit applicable under paragraph (e), a notice under Rule 26bis.1(a) adding
the priority claim.
(d) The submission of a request under paragraph (a) may be subjected by
the receiving Office to the payment to it, for its own benefit, of a fee for
requesting restoration, payable within the time limit applicable under
paragraph (e). The amount of that fee, if any, shall be fixed by the receiving
Office. The time limit for payment of the fee may be extended, at the option of
the receiving Office, for a period of up to two months from the expiration of the
time limit applicable under paragraph (e).
(e) The time limit referred to in paragraphs (b)(i), (c) and (d) shall be two
months from the date on which the priority period expired, provided that, where
the applicant makes a request for early publication under Article 21(2)(b), any
request under paragraph (a) or any notice referred to in paragraph (c) submitted,
or any fee referred to in paragraph (d) paid, after the technical preparations for
international publication have been completed shall be considered as not having
been submitted or paid in time.
(f) The receiving Office may require that a declaration or other evidence in
support of the statement of reasons referred to in paragraph (b)(iii) be filed with
it within a time limit which shall be reasonable under the circumstances. The
applicant may furnish to the International Bureau a copy of any such declaration
or other evidence filed with the receiving Office, in which case the International
Bureau shall include such copy in its files.
(g) The receiving Office shall not refuse, totally or in part, a request under
paragraph (a) without giving the applicant the opportunity to make observations
on the intended refusal within a time limit which shall be reasonable under the
circumstances. Such notice of intended refusal by the receiving Office may be
sent to the applicant together with any invitation to file a declaration or other
evidence under paragraph (f).
(h) The receiving Office shall promptly:
(i) notify the International Bureau of the receipt of a request under
paragraph (a);
(ii) make a decision upon the request;
(iii) notify the applicant and the International Bureau of its decision and
the criterion for restoration upon which the decision was based.

71

Regulations under the PCT (as in force from January 1, 2013)

(i) Each receiving Office shall inform the International Bureau of which of
the criteria for restoration it applies and of any subsequent changes in that
respect. The International Bureau shall promptly publish such information in
the Gazette.
(j) If, on October 5, 2005, paragraphs (a) to (i) are not compatible with the
national law applied by the receiving Office, those paragraphs shall not apply in
respect of that Office for as long as they continue not to be compatible with that
law, provided that the said Office informs the International Bureau accordingly
by April 5, 2006. The information received shall be promptly published by the
International Bureau in the Gazette. 6
Rule 26ter
Correction or Addition of Declarations under Rule 4.17
26ter.1 Correction or Addition of Declarations
The applicant may correct or add to the request any declaration referred to in
Rule 4.17 by a notice submitted to the International Bureau within a time limit
of 16 months from the priority date, provided that any notice which is received
by the International Bureau after the expiration of that time limit shall be
considered to have been received on the last day of that time limit if it reaches it
before the technical preparations for international publication have been
completed.
26ter.2 Processing of Declarations
(a) Where the receiving Office or the International Bureau finds that any
declaration referred to in Rule 4.17 is not worded as required or, in the case of
the declaration of inventorship referred to in Rule 4.17(iv), is not signed as
required, the receiving Office or the International Bureau, as the case may be,
may invite the applicant to correct the declaration within a time limit of
16 months from the priority date.
(b) Where the International Bureau receives any declaration or correction
under Rule 26ter.1 after the expiration of the time limit under Rule 26ter.1, the
International Bureau shall notify the applicant accordingly and shall proceed as
provided for in the Administrative Instructions.

Rule 32
Extension of Effects of International Application
to Certain Successor States
32.1 Extension of International Application to Successor State
(a) The effects of any international application whose international filing
date falls in the period defined in paragraph (b) are extended to a State (“the
successor State”) whose territory was, before the independence of that State,
part of the territory of a Contracting State designated in the international
application which subsequently ceased to exist (“the predecessor State”),
provided that the successor State has become a Contracting State through the
deposit, with the Director General, of a declaration of continuation the effect of
which is that the Treaty is applied by the successor State.
(b) The period referred to in paragraph (a) starts on the day following the
last day of the existence of the predecessor State and ends two months after the
date on which the declaration referred to in paragraph (a) was notified by the
Director General to the Governments of the States party to the Paris Convention
for the Protection of Industrial Property. However, where the date of
independence of the successor State is earlier than the date of the day following
the last day of the existence of the predecessor State, the successor State may
declare that the said period starts on the date of its independence; such a
declaration shall be made together with the declaration referred to in
paragraph (a) and shall specify the date of independence.

75

Regulations under the PCT (as in force from January 1, 2013)

(c) Information on any international application whose filing date falls
within the applicable period under paragraph (b) and whose effect is extended to
the successor State shall be published by the International Bureau in the Gazette.
32.2 Effects of Extension to Successor State
(a) Where the effects of the international application are extended to the
successor State in accordance with Rule 32.1,
(i) the successor State shall be considered as having been designated in
the international application, and
(ii) the applicable time limit under Article 22 or 39(1) in relation to that
State shall be extended until the expiration of at least six months from the date
of the publication of the information under Rule 32.1(c).
(b) The successor State may fix a time limit which expires later than that
provided in paragraph (a)(ii).
The International Bureau shall publish
information on such time limits in the Gazette.
Rule 33
Relevant Prior Art for the International Search
33.1 Relevant Prior Art for the International Search
(a) For the purposes of Article 15(2), relevant prior art shall consist of
everything which has been made available to the public anywhere in the world
by means of written disclosure (including drawings and other illustrations) and
which is capable of being of assistance in determining that the claimed invention
is or is not new and that it does or does not involve an inventive step (i.e., that it
is or is not obvious), provided that the making available to the public occurred
prior to the international filing date.
(b) When any written disclosure refers to an oral disclosure, use, exhibition,
or other means whereby the contents of the written disclosure were made
available to the public, and such making available to the public occurred on a
date prior to the international filing date, the international search report shall
separately mention that fact and the date on which it occurred if the making
available to the public of the written disclosure occurred on a date which is the
same as, or later than, the international filing date.
(c) Any published application or any patent whose publication date is the
same as, or later than, but whose filing date, or, where applicable, claimed
priority date, is earlier than the international filing date of the international
application searched, and which would constitute relevant prior art for the
purposes of Article 15(2) had it been published prior to the international filing
date, shall be specially mentioned in the international search report.

76

Regulations under the PCT (as in force from January 1, 2013)

33.2 Fields to Be Covered by the International Search
(a) The international search shall cover all those technical fields, and shall
be carried out on the basis of all those search files, which may contain material
pertinent to the invention.
(b) Consequently, not only shall the art in which the invention is classifiable
be searched but also analogous arts regardless of where classified.
(c) The question what arts are, in any given case, to be regarded as
analogous shall be considered in the light of what appears to be the necessary
essential function or use of the invention and not only the specific functions
expressly indicated in the international application.
(d) The international search shall embrace all subject matter that is
generally recognized as equivalent to the subject matter of the claimed invention
for all or certain of its features, even though, in its specifics, the invention as
described in the international application is different.
33.3 Orientation of the International Search
(a) International search shall be made on the basis of the claims, with due
regard to the description and the drawings (if any) and with particular emphasis
on the inventive concept towards which the claims are directed.
(b) In so far as possible and reasonable, the international search shall cover
the entire subject matter to which the claims are directed or to which they might
reasonably be expected to be directed after they have been amended.
Rule 34
Minimum Documentation
34.1 Definition
(a) The definitions contained in Article 2(i) and (ii) shall not apply for the
purposes of this Rule.
(b) The documentation referred to in Article 15(4) (“minimum
documentation”) shall consist of:
(i) the “national patent documents” as specified in paragraph (c),
(ii) the published international (PCT) applications, the published regional
applications for patents and inventors’ certificates, and the published regional
patents and inventors’ certificates,
(iii) such other published items of non-patent literature as the International
Searching Authorities shall agree upon and which shall be published in a list by
the International Bureau when agreed upon for the first time and whenever
changed.

77

Regulations under the PCT (as in force from January 1, 2013)

(c) Subject to paragraphs (d) and (e), the “national patent documents” shall

Reichspatentamt of Germany, Japan, the former Soviet Union, Switzerland (in
the French and German languages only), the United Kingdom, and the
United States of America,
(ii) the patents issued by the Federal Republic of Germany, the
People’s Republic of China, the Republic of Korea and the Russian Federation,
(iii) the patent applications, if any, published in and after 1920 in the
countries referred to in items (i) and (ii),
(iv) the inventors’ certificates issued by the former Soviet Union,
(v) the utility certificates issued by, and the published applications for
utility certificates of, France,
(vi) such patents issued by, and such patent applications published in, any
other country after 1920 as are in the English, French, German or Spanish
language and in which no priority is claimed, provided that the national Office
of the interested country sorts out these documents and places them at the
disposal of each International Searching Authority.
(d) Where an application is republished once (for example, an
Offenlegungsschrift as an Auslegeschrift) or more than once, no International
Searching Authority shall be obliged to keep all versions in its documentation;
consequently, each such Authority shall be entitled not to keep more than one
version. Furthermore, where an application is granted and is issued in the form
of a patent or a utility certificate (France), no International Searching Authority
shall be obliged to keep both the application and the patent or utility certificate
(France) in its documentation; consequently, each such Authority shall be
entitled to keep either the application only or the patent or utility certificate
(France) only.
(e) Any International Searching Authority whose official language, or one
of whose official languages, is not Chinese, Japanese, Korean, Russian or
Spanish is entitled not to include in its documentation those patent documents of
the People’s Republic of China, Japan, the Republic of Korea, the
Russian Federation and the former Soviet Union as well as those patent
documents in the Spanish language, respectively, for which no abstracts in the
English language are generally available. English abstracts becoming generally
available after the date of entry into force of these Regulations shall require the
inclusion of the patent documents to which the abstracts refer no later than six
months after such abstracts become generally available. In case of the
interruption of abstracting services in English in technical fields in which
English abstracts were formerly generally available, the Assembly shall take
78

Regulations under the PCT (as in force from January 1, 2013)

appropriate measures to provide for the prompt restoration of such services in
the said fields.
(f) For the purposes of this Rule, applications which have only been laid
open for public inspection are not considered published applications.

Editor’s Note: Rule 47.1(c) and (e) shall apply to any international application whose
international filing date is on or after January 1, 2004 and in respect of a designated Office
which has made a notification under paragraph (2) of the decisions of the Assembly set out in

in Article 22(1) was not compatible with the national law applied by that Office on
October 3, 2001), and which has not withdrawn that notification under paragraph (3) of those
decisions, as though the reference in each of Rule 47.1(c) and (e) to “28 months” was a
reference to “19 months,” with the consequence that two notifications under Rule 47.1(c)
shall, if applicable, be sent in respect of such an application.

an indication of the wish of the applicant that the international application is to
be treated as an application for that kind of protection and the designated Office
shall inform the applicant accordingly.

national law provides for restoration of the right of priority based on that
criterion or on a criterion which, from the viewpoint of applicants, is more
favorable than that criterion.

Rule 26bis.3 shall not be effective in a designated State where the designated
110

Regulations under the PCT (as in force from January 1, 2013)

(e) No designated State shall be bound by a decision of the receiving Office
refusing a request under Rule 26bis.3 for restoration of the right of priority.

request for restoration submitted to that designated Office under Rule 49ter.2(a)
within the time limit under that Rule.

49ter.2 Restoration of Right of Priority by Designated Office
(a) Where the international application claims the priority of an earlier
application and has an international filing date which is later than the date on
which the priority period expired but within the period of two months from that
date, the designated Office shall, on the request of the applicant in accordance
with paragraph (b), restore the right of priority if the Office finds that a criterion
applied by it (“criterion for restoration”) is satisfied, namely, that the failure to
file the international application within the priority period:
(i) occurred in spite of due care required by the circumstances having
been taken; or
(ii) was unintentional.
Each designated Office shall apply at least one of those criteria and may apply
both of them.

(iii) where the international application under international preliminary
examination claims the priority of an earlier application and has an international
filing date which is later than the date on which the priority period expired but
within the period of two months from that date, the filing date of such earlier
application, unless the International Preliminary Examining Authority considers
that the priority claim is not valid for reasons other than the fact that the
international application has an international filing date which is later than the
date on which the priority period expired.
64.2 Non-Written Disclosures
In cases where the making available to the public occurred by means of an
oral disclosure, use, exhibition or other non-written means (“non-written
disclosure”) before the relevant date as defined in Rule 64.1(b) and the date of
such non-written disclosure is indicated in a written disclosure which has been
made available to the public on a date which is the same as, or later than, the
relevant date, the non-written disclosure shall not be considered part of the prior
art for the purposes of Article 33(2) and (3). Nevertheless, the international
preliminary examination report shall call attention to such non-written
disclosure in the manner provided for in Rule 70.9.

64.3 Certain Published Documents
In cases where any application or any patent which would constitute prior
art for the purposes of Article 33(2) and (3) had it been published prior to the
relevant date referred to in Rule 64.1 was published on a date which is the same
as, or later than, the relevant date but was filed earlier than the relevant date or
claimed the priority of an earlier application which had been filed prior to the
relevant date, such published application or patent shall not be considered part
of the prior art for the purposes of Article 33(2) and (3). Nevertheless, the
international preliminary examination report shall call attention to such
application or patent in the manner provided for in Rule 70.10.
Rule 65
Inventive Step or Non-Obviousness
65.1 Approach to Prior Art
For the purposes of Article 33(3), the international preliminary examination
shall take into consideration the relation of any particular claim to the prior art
as a whole. It shall take into consideration the claim’s relation not only to
individual documents or parts thereof taken separately but also its relation to
combinations of such documents or parts of documents, where such
combinations are obvious to a person skilled in the art.
65.2 Relevant Date
For the purposes of Article 33(3), the relevant date for the consideration of
inventive step (non-obviousness) is the date prescribed in Rule 64.1.

purposes of the international preliminary examination.
(d-bis) A rectification of an obvious mistake that is authorized under
Rule 91.1 shall, subject to Rule 66.4bis, be taken into account by the
International Preliminary Examining Authority for the purposes of the
international preliminary examination.
(e) Claims relating to inventions in respect of which no international search
report has been established need not be the subject of international preliminary
examination.
66.1bis Written Opinion of the International Searching Authority
(a) Subject to paragraph (b), the written opinion established by the
International Searching Authority under Rule 43bis.1 shall be considered to be a
written opinion of the International Preliminary Examining Authority for the
purposes of Rule 66.2(a).
(b) An International Preliminary Examining Authority may notify the
International Bureau that paragraph (a) shall not apply to the procedure before it
in respect of written opinions established under Rule 43bis.1 by the International
Searching Authority or Authorities specified in the notification, provided that
such a notification shall not apply to cases where the national Office or
intergovernmental organization that acted as International Searching Authority
is also acting as International Preliminary Examining Authority.
The
International Bureau shall promptly publish any such notification in the
Gazette. 15
(c) Where the written opinion established by the International Searching

133

Regulations under the PCT (as in force from January 1, 2013)

account by the International Preliminary Examining Authority in proceeding
under Rule 66.2(a).
66.2 Written Opinion of the International Preliminary Examining Authority
(a) If the International Preliminary Examining Authority
(i) considers that any of the situations referred to in Article 34(4) exists,
(ii) considers that the international preliminary examination report should
be negative in respect of any of the claims because the invention
claimed therein does not appear to be novel, does not appear to
involve an inventive step (does not appear to be non-obvious), or does
not appear to be industrially applicable,
(iii) notices that there is some defect in the form or contents of the
international application under the Treaty or these Regulations,
(iv) considers that any amendment goes beyond the disclosure in the
international application as filed,
(v) wishes to accompany the international preliminary examination report
by observations on the clarity of the claims, the description, and the
drawings, or the question whether the claims are fully supported by
the description,
(vi) considers that a claim relates to an invention in respect of which no
international search report has been established and has decided not to
carry out the international preliminary examination in respect of that
claim, or
(vii) considers that a nucleotide and/or amino acid sequence listing is not
available to it in such a form that a meaningful international
preliminary examination can be carried out,
the said Authority shall notify the applicant accordingly in writing. Where the
national law of the national Office acting as International Preliminary
Examining Authority does not allow multiple dependent claims to be drafted in
a manner different from that provided for in the second and third sentences of
Rule 6.4(a), the International Preliminary Examining Authority may, in case of
failure to use that manner of claiming, apply Article 34(4)(b). In such case, it
shall notify the applicant accordingly in writing.
(b) The notification shall fully state the reasons for the opinion of the
International Preliminary Examining Authority.
(c) The notification shall invite the applicant to submit a written reply
together, where appropriate, with amendments.
(d) The notification shall fix a time limit for the reply. The time limit shall
be reasonable under the circumstances. It shall normally be two months after
134

Regulations under the PCT (as in force from January 1, 2013)

the date of notification. In no case shall it be shorter than one month after the
said date. It shall be at least two months after the said date where the
international search report is transmitted at the same time as the notification. It
shall, subject to paragraph (e), not be more than three months after the said date.
(e) The time limit for replying to the notification may be extended if the
applicant so requests before its expiration.
66.3 Formal Response to the International Preliminary Examining Authority
(a) The applicant may respond to the invitation referred to in Rule 66.2(c)
of the International Preliminary Examining Authority by making amendments or
– if he disagrees with the opinion of that Authority – by submitting arguments,
as the case may be, or do both.
(b) Any response shall be submitted directly to the International
Preliminary Examining Authority.
66.4 Additional Opportunity for Submitting Amendments or Arguments
(a) If the International Preliminary Examining Authority wishes to issue
one or more additional written opinions, it may do so, and Rules 66.2 and 66.3
shall apply.
(b) On the request of the applicant, the International Preliminary Examining
Authority may give him one or more additional opportunities to submit
amendments or arguments.
66.4bis Consideration of Amendments, Arguments and Rectifications of
Obvious Mistakes
Amendments, arguments and rectifications of obvious mistakes need not be
taken into account by the International Preliminary Examining Authority for the
purposes of a written opinion or the international preliminary examination report
if they are received by, authorized by or notified to that Authority, as applicable,
after it has begun to draw up that opinion or report.
66.5 Amendment
Any change, other than the rectification of an obvious mistake, in the
claims, the description, or the drawings, including cancellation of claims,
omission of passages in the description, or omission of certain drawings, shall be
considered an amendment.
66.6 Informal Communications with the Applicant
The International Preliminary Examining Authority may, at any time,
communicate informally, over the telephone, in writing, or through personal
interviews, with the applicant. The said Authority shall, at its discretion, decide
whether it wishes to grant more than one personal interview if so requested by
135

Regulations under the PCT (as in force from January 1, 2013)

the applicant, or whether it wishes to reply to any informal written
communication from the applicant.
66.7 Copy and Translation of Earlier Application Whose Priority Is Claimed
(a) If the International Preliminary Examining Authority needs a copy of
the earlier application whose priority is claimed in the international application,
the International Bureau shall, on request, promptly furnish such copy. If that
copy is not furnished to the International Preliminary Examining Authority
because the applicant failed to comply with the requirements of Rule 17.1, and if
that earlier application was not filed with that Authority in its capacity as a
national Office or the priority document is not available to that Authority from a
digital library in accordance with the Administrative Instructions, the
international preliminary examination report may be established as if the priority
had not been claimed.
(b) If the application whose priority is claimed in the international
application is in a language other than the language or one of the languages of
the International Preliminary Examining Authority, that Authority may, where
the validity of the priority claim is relevant for the formulation of the opinion
referred to in Article 33(1), invite the applicant to furnish a translation in the
said language or one of the said languages within two months from the date of
the invitation. If the translation is not furnished within that time limit, the
international preliminary examination report may be established as if the priority
had not been claimed.
66.8 Form of Amendments
(a) Subject to paragraph (b), when amending the description or the
drawings, the applicant shall be required to submit a replacement sheet for every
sheet of the international application which, on account of an amendment,
differs from the sheet previously filed. The replacement sheet or sheets shall be
accompanied by a letter which shall draw attention to the differences between
the replaced sheets and the replacement sheets, shall indicate the basis for the
amendment in the application as filed and shall preferably also explain the
reasons for the amendment.
(b) Where the amendment consists in the deletion of passages or in minor
alterations or additions, the replacement sheet referred to in paragraph (a) may
be a copy of the relevant sheet of the international application containing the
alterations or additions, provided that the clarity and direct reproducibility of
that sheet are not adversely affected. To the extent that any amendment results
in the cancellation of an entire sheet, that amendment shall be communicated in
a letter which shall preferably also explain the reasons for the amendment.

136

Regulations under the PCT (as in force from January 1, 2013)

(c) When amending the claims, Rule 46.5 shall apply mutatis mutandis.
The set of claims submitted under Rule 46.5 as applicable by virtue of this
paragraph shall replace all the claims originally filed or previously amended
under Articles 19 or 34, as the case may be.
Rule 67
Subject Matter under Article 34(4)(a)(i)
67.1 Definition
No International Preliminary Examining Authority shall be required to carry
out an international preliminary examination on an international application if,
and to the extent to which, its subject matter is any of the following:
(i) scientific and mathematical theories,
(ii) plant or animal varieties or essentially biological processes for the
production of plants and animals, other than microbiological processes and the
products of such processes,
(iii) schemes, rules or methods of doing business, performing purely
mental acts or playing games,
(iv) methods for treatment of the human or animal body by surgery or
therapy, as well as diagnostic methods,
(v) mere presentations of information,
(vi) computer programs to the extent that the International Preliminary
Examining Authority is not equipped to carry out an international preliminary
examination concerning such programs.
Rule 68
Lack of Unity of Invention
(International Preliminary Examination)
68.1 No Invitation to Restrict or Pay
Where the International Preliminary Examining Authority finds that the
requirement of unity of invention is not complied with and chooses not to invite
the applicant to restrict the claims or to pay additional fees, it shall proceed with
the international preliminary examination, subject to Article 34(4)(b) and
Rule 66.1(e), in respect of the entire international application, but shall indicate,
in any written opinion and in the international preliminary examination report,
that it considers that the requirement of unity of invention is not fulfilled and it
shall specify the reasons therefor.
68.2 Invitation to Restrict or Pay
Where the International Preliminary Examining Authority finds that the
requirement of unity of invention is not complied with and chooses to invite the
137

Regulations under the PCT (as in force from January 1, 2013)

applicant, at his option, to restrict the claims or to pay additional fees, the
invitation shall:
(i) specify at least one possibility of restriction which, in the opinion of
the International Preliminary Examining Authority, would be in compliance
with the applicable requirement;
(ii) specify the reasons for which the international application is not
considered as complying with the requirement of unity of invention;
(iii) invite the applicant to comply with the invitation within one month
from the date of the invitation;
(iv) indicate the amount of the required additional fees to be paid in case
the applicant so chooses; and
(v) invite the applicant to pay, where applicable, the protest fee referred
to in Rule 68.3(e) within one month from the date of the invitation, and indicate
the amount to be paid.
68.3 Additional Fees
(a) The amount of the additional fees due for international preliminary
examination under Article 34(3)(a) shall be determined by the competent
International Preliminary Examining Authority.
(b) The additional fees due for international preliminary examination under
Article 34(3)(a) shall be payable direct to the International Preliminary
Examining Authority.
(c) Any applicant may pay the additional fees under protest, that is,
accompanied by a reasoned statement to the effect that the international
application complies with the requirement of unity of invention or that the
amount of the required additional fees is excessive. Such protest shall be
examined by a review body constituted in the framework of the International
Preliminary Examining Authority which, to the extent that it finds the protest
justified, shall order the total or partial reimbursement to the applicant of the
additional fees. On the request of the applicant, the text of both the protest and
the decision thereon shall be notified to the elected Offices as an annex to the
international preliminary examination report.
(d) The membership of the review body referred to in paragraph (c) may
include, but shall not be limited to, the person who made the decision which is
the subject of the protest.
(e) The examination of a protest referred to in paragraph (c) may be
subjected by the International Preliminary Examining Authority to the payment
to it, for its own benefit, of a protest fee. Where the applicant has not, within the
time limit under Rule 68.2(v), paid any required protest fee, the protest shall be

138

Regulations under the PCT (as in force from January 1, 2013)

considered not to have been made and the International Preliminary Examining
Authority shall so declare. The protest fee shall be refunded to the applicant
where the review body referred to in paragraph (c) finds that the protest was
entirely justified.
68.4 Procedure in the Case of Insufficient Restriction of the Claims
If the applicant restricts the claims but not sufficiently to comply with the
requirement of unity of invention, the International Preliminary Examining
Authority shall proceed as provided in Article 34(3)(c).
68.5 Main Invention
In case of doubt which invention is the main invention for the purposes of
Article 34(3)(c), the invention first mentioned in the claims shall be considered
the main invention.
Rule 69
Start of and Time Limit for
International Preliminary Examination

International Searching Authority also acts as International Preliminary
Examining Authority, the international preliminary examination may, if that
national Office or intergovernmental organization so wishes and subject to
paragraphs (d) and (e), start at the same time as the international search.

139

Regulations under the PCT (as in force from January 1, 2013)

(b-bis) Where, in accordance with paragraph (b), the national Office or
intergovernmental organization that acts as both International Searching
Authority and International Preliminary Examining Authority wishes to start the
international preliminary examination at the same time as the international
search and considers that all of the conditions referred to in Article 34(2)(c)(i)
to (iii) are fulfilled, that national Office or intergovernmental organization need
not, in its capacity as International Searching Authority, establish a written
opinion under Rule 43bis.1.
(c) Where the statement concerning amendments contains an indication that
amendments under Article 19 are to be taken into account (Rule 53.9(a)(i)), the
International Preliminary Examining Authority shall not start the international
preliminary examination before it has received a copy of the amendments
concerned.

(iii) the mistake is in an amendment under Article 19, unless the
International Preliminary Examining Authority is competent to
authorize the rectification of such mistake under paragraph (b)(iii); or
(iv) the mistake is in a priority claim or in a notice correcting or adding a
priority claim under Rule 26bis.1(a), where the rectification of the
mistake would cause a change in the priority date;
provided that this paragraph shall not affect the operation of Rules 20.4, 20.5,
26bis and 38.3.
