            Re: Implementation of IPC Reform
            _____________________________


            Madam,
            Sir,

                 At its thirty-fourth session, held in February 2004, the Committee of
            Experts of the IPC Union decided to postpone entering into force of the reformed
            IPC for one year, until January 1, 2006 (see document IPC/CE/34/10,
            paragraph 43).

                  This decision was taken to provide more time to industrial property offices
            for the accommodation of their internal systems to the requirements of IPC
            reform and better opportunities for the creation of the Master Classification
            Database (MCD) which will include the bibliographic data of the worldwide
            collection of patent documents. When created, the Master Classification
            Database should contain the IPC data of patent documents classified only
            according to the next, eighth, edition of the IPC (reformed IPC) which edition
            will be published in June 2005.

                  This will provide possibilities for performing patent searches with the use
            of the eighth edition of the IPC only and will eliminate the need to rely on
            superseded previous IPC editions. The Committee of Experts agreed that
            implementation of IPC reform by industrial property offices should be
            considered at its thirty-fifth session to be held from October 25 to 29, 2004.

                 The purpose of this Circular is to collect information about the current stage
            of implementation of IPC reform, respective plans of industrial property offices
            and problems encountered in the implementation of the reform.

                                                                                                                     /...

      The attached questionnaire covers four areas relating to implementation of
IPC reform: recording of IPC symbols on the front page of patent documents;
checking the validity of IPC symbols on published patent documents;
submission of the bibliographic data of new patent documents to the MCD; and
reclassification of retrospective patent collections for loading the reclassification
data in the MCD.

      You are kindly invited to complete the questionnaire in light of the
information above and additional explanations provided in the questionnaire. It
would be appreciated if the questionnaire could be returned to the International
Bureau by October 1, 2004. The electronic version of the questionnaire is
available at the address: http://www.wipo.int/classifications/ipc/en/index.html,
under the heading “Circulars,” and should be returned to the e-mail address
ipc.mail@wipo.int.

                                                         Yours sincerely,

Recording of IPC symbols on the front page of patent documents

      From January 1, 2006, onwards, IPC symbols should be presented on the front page
of patent documents in a tabular form, with the use of various font styles for distinguishing
different types of symbols (see the revised WIPO Standard ST.10/C attached to
this questionnaire).

1.   Please describe any problems that your Office may have with this presentation of
IPC symbols.

Checking the validity of IPC symbols on published patent documents

      The IPC valid symbols file, produced by the International Bureau of WIPO, is used by
offices for checking the validity of IPC symbols assigned to patent documents before their
publication. In the pre-reformed IPC, the IPC valid symbols file was produced for each
edition of the IPC and underwent no changes until a new edition entered into force. In the
reformed IPC, its core level will be stable during three-year revision cycles, however,
amendments to the advanced level may be made every three months. The International
Bureau will produce the IPC valid symbols file for the eighth edition of the IPC in time for its
entering into force and plans to update it, in the future, every three months, according to the
amendments of the advanced level. Offices which plan to use the advanced level for
classifying their published patent documents will need to foresee the periodical replacement
of the valid symbols file in their internal IT systems.
Annex to WIPO Circular No. IPC 123, page 2



2.    If your Office plans to use the advanced level of the reformed IPC, please describe
any problems with the periodical update of the IPC valid symbols file that your Office
can foresee.

Submission of the bibliographic data of new patent documents to the Master Classification
Database (MCD)

      The bibliographic data of new patent documents published by offices after
January 1, 2006, should regularly be submitted to the European Patent Office (EPO) for the
inclusion in the MCD. These data should be delivered before the publication of patent
documents in order to ensure the timely inclusion of the data in the MCD. For recording of
symbols of the reformed IPC on machine-readable records, the revised WIPO Standard ST.8
has been adopted. The revised standard is attached to this questionnaire. For offices wishing to
use the XML format for processing of patent documents, a new WIPO Standard ST.36
(“Recommendation for the Processing of Patent Documents using XML”) is under elaboration.

3.   From which date in 2005 does your Office plan to start sending the bibliographic data of
new patent documents classified according to the eighth edition of the IPC?

...........................................................................................................................................

4.   If your Office plans to use the revised Standard ST.8 for recording IPC symbols, please
provide details relating to formatting of the bibliographic data.

                                       Yes                                                   No
Annex to WIPO Circular No. IPC 123, page 3



Reclassification of retrospective patent collections for loading the reclassification data in
the MCD

      Reclassification according to the eighth edition of the IPC of patent documents
published before January 1, 2006, and belonging to the PCT Minimum Documentation, as
defined in the PCT Rule 34, will be ensured by a special committee consisting of major
industrial property offices. Industrial property offices whose documents are not included in
the PCT Minimum Documentation are encouraged to carry out reclassification of their
retrospective patent collections. The questions below concern such industrial property
offices. With a view to alleviating the workload of reclassification, offices, whose documents
have patent family members in the PCT Minimum Documentation, may request that these
documents be reclassified by automatic propagation of the reclassification data from the PCT
Minimum Documentation. However, documents which have no such family members, for
example, filed by residents of the country without filing abroad, should be reclassified by the
industrial property offices concerned.

6.    Is your Office prepared to carry out reclassification according to the eighth edition of
the IPC of your patent documents published before January 1, 2006:

        (a)      of a complete collection of patent documents?

                                       Yes                                                   No

     (b) of only patent documents having no family members in the PCT
Minimum Documentation?

                                       Yes                                                   No

7.      If the response to questions 6(a) or 6(b) is “Yes”:

      (a) when does your Office plan to carry out reclassification of patent documents
published before January 1, 2006, and make the results of reclassification available to the
EPO for loading in the MCD?

...........................................................................................................................................

        (b)      when would your Office be able to send the test reclassification data to the EPO?

...........................................................................................................................................

      (c) will your Office use the core or the advanced level of the reformed IPC for
reclassification of retrospective patent collections?

                              Core level                                   Advanced level
Annex to WIPO Circular No. IPC 123, page 4



      (d) does your Office plan to use for sending the reclassification data a modified
WIPO Standard ST.32 (including IPC information according to the revised Standard ST.8),
the future Standard ST.36 or another standard (please, specify)?

                          ST.32                                   ST.36                    Another standard

                                     Editorial Note prepared by the International Bureau




        The Standard and Documentation Working Group (SDWG) of the Standing Committee on Information
Technologies (SCIT) adopted the revisions of paragraphs 2 and 3 of Standard ST.10/C at its third session on May 8,
2003. These revisions incorporate changes made necessary by the IPC reform initiative. In view of the postponement of
the entering into force of the reformed IPC until January 1, 2006 (see paragraphs 36 to 47 of document IPC/CE/34/10),
paragraphs 2 and 3 of the Standard will come into force on January 1, 2006, and not on January 1, 2005, as stated in paragraph 3.

         Industrial property offices are asked to implement the new versions of paragraphs 2 and 3 of Standard ST.10/C
for all patent documents with a publication date from January 1, 2006, onwards. For patent documents published prior
to that date, the previous text of paragraphs 2 and 3 of the Standard should continue to be used.

       The previous versions of paragraphs 2 and 3 of Standard ST.10/C, valid until December 31, 2005, are
reproduced in the Annex to the new Standard ST.10/C.

                                         at its fourth session on January 30, 2004




PRESENTATION OF DATES

1.      For the representation of calendar dates according to the Gregorian calendar, which are printed or displayed in
industrial property documents, in entries in official gazettes or in electronic records, WIPO Standard ST.2 is applicable.


PRESENTATION OF CLASSIFICATION SYMBOLS

2.      The recommended abbreviation of the International Patent Classification is “Int.Cl.”. The version indicator (year)
has to be placed in round brackets after the abbreviation “Int.Cl.”, if the set of IPC symbols on the document includes at
least one core level symbol.

The recommended presentation of classification symbols in printed or formatted display form is as follows:

–       classification symbols presented in a tabular form, in such a manner as to facilitate machine transcription;

–       the core level symbols printed in regular font style and the advanced level symbols in italics;

–       the invention information symbols printed in bold font style and the other information symbols in regular;

–       the version indicator for each advanced level symbol (year, month) placed in round brackets after each advanced
        level symbol.

3.      One sample representation of IPC classification symbols and indicators is:

                     Int. Cl. (2005)
                     B28B 5/02
                     B28B 1/29 (2006.03)
                     H05B 3/18 (2007.06)

        Where:       B28B 5/02      is core level classification (regular font style) and invention information
                                    (bold font style);

                     B28B 1/29      is advanced level classification (italics font style) and invention information
                                    (bold font style); and

                     H05B 3/18      is advanced level classification (italics font style) and non-invention information
                                    (regular font style).

IPC symbols are defined in Part 5 of the WIPO Handbook on Industrial Property Information and Documentation and in
the latest version of the Guide to the IPC.

This presentation is effective beginning with the January 1, 2005, edition of the IPC.*

4.      The recommended abbreviation of the International Classification for Industrial Designs is “LOC”. According to
the recommendation of the Committee of Experts of the Locarno Union, the edition of the Classification should be
indicated by an Arabic numeral in parentheses, e.g., LOC (6) Cl. 8-05. Classification symbols should be presented with
all elements of a given symbol contained in the same line, preferably in such a manner as to facilitate machine
transcription. If the numbers of several classes or subclasses must be indicated for one and the same subject matter,
the classes should be separated by semicolons and subclasses by commas (for example, LOC (6) Cl. 8-05, 08; 11-01).

PRESENTATION OF APPLICATION NUMBERS

5.      Experience has shown the need for application numbers to be presented in a clear, unambiguous manner. The
considerations given below apply equally to all presentations of application numbers of patent documents whether to the
application number accorded to the application filed in the issuing industrial property office or that filed in the priority
country or with an organization.

6.      The presentation of the application number should preferably be:

        (a)     exactly in the manner used by the country or organization concerned in full, or

        (b)     abbreviated to the minimum significant part, enabling the application to be uniquely identified.

7.     When the application number is abbreviated to the minimum significant part (deletion of letters and numerals
given by the country or organization concerned for internal or special purposes such as check digits, classification
marks, etc.), a need exists for a more uniform presentation thereof, in particular when information presented on the first
page of patent documents is composed for printing (e.g., typeset, photocomposed, retyped, etc.). An application
number, as represented by the country or organization concerned, may therefore be represented in a more uniform
manner using the following rules:

       (a)   if the number contains a full stop, a comma, or perhaps a space, one or more of these characters or
spaces may be omitted. One or more of these characters or spaces may be inserted for the sake of legibility;

       (b)     if the number contains a slash or a hyphen, these characters must be retained. A hyphen may be
replaced by a slash;

       (c)      the sequence of characters should be left in its original order, e.g., the digits indicating the year of filing of
the application must be printed in their original positions;

        (d)   no character or set of characters forming the minimum significant part of the application number, other
than those characters mentioned in subparagraphs (a) and (b), above, should be altered, e.g.:

                 (i)  the year of the Emperor’s reign appearing in Japanese application numbers should not be altered
according to the Gregorian calendar;

                 (ii)   no infilling zeros should be removed or added, e.g., 74/0069 should not be printed as 74/69 or
74/00069;

         (e)     in the case of a utility model application number, a letter or set of characters may be used by the country
or organization concerned for uniquely defining the application. The letter or set of characters should be removed and
the letter ”U” inserted after the application number, separated by two blank spaces. The words “utility model” may be
added in the plain language of the publishing country or organization;

        (f)     year designations according to the Gregorian calendar should be represented by four digits;

        (g)     in the case of PCT application numbers, the alphanumeric string consisting of the letters “PCT,” the
two-letter code identifying the receiving office, and the year, is a significant part of the application number and must
not be omitted.

For guidance, two tables setting out the form of presentation of application numbers currently used by several countries
or organizations, the minimum significant part of the numbers and the recommended presentation in abbreviated form as
priority application numbers, are given in the Appendix to this Standard.


IDENTIFICATION OF COUNTRIES, ORGANIZATIONS AND OTHER ENTITIES ISSUING OR REGISTERING PATENT
DOCUMENTS

8.      Two-letter codes according to WIPO Standard ST.3 should be used when indicating:

        (a)     the country, organization or other entity in which a convention priority application was filed;

        (b)     the country, organization or other entity that published prior art patent documents; and

        (c)    the country, organization or other entity publishing the patent document. The name of the country,
organization or other entity publishing the patent document may be given in plain language, in addition to the ST.3 code,
if so desired.

Ref.: Standards – ST.10/C                                                                                        page: 3.10.3.3




USE AND PRESENTATION OF CHECK DIGITS

9.       Check digits are used by several industrial property offices in relation to application numbers or publication
numbers for the purposes of internal control. Different systems are in use by different industrial property offices. Most
systems give rise to a single control character, either a numeral from “0” to “9” or a letter from “A” to “Z”. It is clear that
the control character has to be associated with the application number or with the publication number so as to facilitate
its control function. However, the control character is not regarded as a significant part of the application number nor as
a significant part of the publication number.

10.     In order to avoid confusion, it is recommended that the following rules be applied if industrial property offices
wish to print a control character associated with an application number or with a publication number on patent
documents or in official gazettes:

       (a)     the control character should consist of a single numeral; letters should not be used so as to avoid
confusion with WIPO Standard ST.16;

        (b)     the control character should be printed immediately after the application number or publication number to
which it refers but separated therefrom by a full stop or by a hyphen and preferably in a type font different from that used
in the number to which it refers;

        (c)    industrial property offices publishing control characters associated with application numbers or with
publication numbers should publish in their official gazette information explaining their use, repeated at intervals of less
than one year.


PRESENTATION OF PRIORITY APPLICATION NUMBERS

11.      Priority application numbers are provided to applicants by industrial property offices in the notifications of the first
filing and in the certificates of priority under the Paris Convention. Priority application numbers are then cited by
applicants when filing a subsequent application for the same or related subject matter before a subsequent industrial
property office in accordance with the Paris Convention. The priority application number can then be used by industrial
property offices to link all related patent document “families” together in databases and computerized search systems.
This ability to create patent families is tremendously valuable to industrial property offices for examination purposes, for
example, when a better date of filing is needed during the prosecution of a later unrelated application. Patent families
also permit patent examiners to review previously published patent documents in a preferred language, if available.
Patent families can help offices save significant classification resources (financial, staffing, etc.) by allowing industrial
property offices to use the classifications of one patent family member for all members of the patent family.

These and other uses of patent families make the accurate recording of the priority application number by applicants a
critical concern of all industrial property offices. Even small deviations from the correct priority application number
format can cause patent documents to not be collected into a patent family. Correction of errors in priority data cause
huge expense for industrial property offices. Therefore, it is critical that the provisions of this section of the standard be
implemented by industrial property offices as soon as possible.

12.     (a)    In order to improve the quality of patent family data and to avoid confusion in the presentation of priority
application numbers, the following recommendations are made:

Industrial property offices (IPOs) should always provide priority application number complying with “Recommended
Presentation in Abbreviated Form as a Priority Application Number” given in the Appendix to the Standard ST.10/C (in
addition to the application number or the minimum significant part of the number) when presenting the application
number of a patent document in the notification of the first filing and in the certificate of priority. The “Recommended
Presentation in Abbreviated Form as a Priority Application Number” should be presented with the Standard ST.3 code
(preferably in a specified line or column along with the title “The number of your priority application, to be used for filing
abroad under the Paris Convention, is”) to be easily recognized as priority number by other IPOs and applicants.

Example of presentation of “Recommended Presentation in Abbreviated Form as a Priority Application Number”:

The number of your priority application, to be used for filing abroad under the Paris Convention, is JP2000-001234

        (b)     Industrial property offices should encourage and facilitate the compliance by applicants of paragraph
12(a) of the Standard ST.10/C when providing the priority application number in subsequent filings.

        The Standards and Documentation Working Group (SDWG) of the Standing Committee on Information
Technologies (SCIT) adopted this revision of Standard ST.8 at its third session on May 8, 2003. This revision of
Standard ST.8 incorporates changes made necessary by the IPC reform initiative. In view of the postponement of the
entering into force of the reformed IPC until January 1, 2006 (see paragraphs 36 to 47 of document IPC/CE/34/10), this
new version of Standard ST.8 will come into force on January 1, 2006.

        Industrial property offices are asked to implement this new version of Standard ST.8 for all patent documents with a
publication date from January 1, 2006, onwards. For patent documents published prior to that date, the previous version of the
Standard should continue to be used.

       The previous version of Standard ST.8, valid until December 31, 2005, is reproduced as an Annex to the new
Standard ST.8.

                       Revision adopted by the SCIT Standards and Documentation Working Group
                                           at its third session on May 8, 2003




INTRODUCTION

1.      This recording convention provides that symbols of the International Patent Classification (IPC) should be
presented on machine-readable records for the exchange of information in machine-readable form in a fixed-length field
in 50 positions, each part of the Int. Cl. symbol being recorded in specific positions and in the manner prescribed.

2.     The examples given are intended to clarify the text and should not be considered as comprehensive.


RECORDING

3.     For the recording of IPC symbols on machine-readable records a field of 50 positions should be allotted for each
symbol, the 50 positions of the field to be used as follows:


         Position(s)                      Content                                   Values

4.       Unused positions in the IPC classification fields Group (positions 5-8) and Subgroup (positions 10-15) should be
left blank. The only other positions that may be left “blank” are the ones reserved for “future use.” All other positions
must be assigned one of the acceptable “values” listed in the table of paragraph 3. Any zero appearing in the symbols
should be recorded.

5.     Considering the numerals appearing after the separating character, the most significant digit (including the case
where it is zero, e.g., subgroup 02) should be in position 10. Any unused positions should be left blank.

6.     Representation of the indicators

Positions 1 to 19: Recording of the parts of the IPC symbols

IPC symbols are defined in Part 5 of the WIPO Handbook on Industrial Property Information and Documentation and in
the latest version of the Guide to the IPC.

Positions 20 to 27: Version indicator

Although in the paper publications a version indicator may contain four or six digits, the version indicator in machine-
readable records contains eight digits, namely YYYYMMDD with Y for year, M for month and D for day.

Position 28 : Classification level

Offices are expected to classify each subject matter only in one level (core or advanced). However, both levels need to
be completely represented in the master classification database and thus a level indicator is needed. The level indicator
is also useful for indicating situations where an office does not classify in either the core or the advanced level
classification, i.e., when an office only assigns classifications to the subclass level. The level indicator enables to make
the difference between core, advanced and subclass levels. The letters C (Core), A (Advanced) and S (Subclass) are
used for this one-digit field.

Position 29: First or later position of symbols

The position of the first invention information classification can be recognized by this field. The letters F and L are used
for first and later position, respectively.

Position 30: Classification value (inventive or non-inventive)

The difference between invention information and other information is important for the retrieval of the information. The
letters I and N are used for the invention and non-invention information, respectively.

Positions 31-38: Action date

The date of assigning the classification symbol (action date) is represented by eight digits, namely YYYYMMDD. This
date can be used to check if a classification needs to be reviewed after revision of the scheme, e.g., in case of creating
new subdivisions.

Position 39: Original and reclassified data

Original data is the first data allotted to the document. In case of a publishing office assigning classification symbols at
the core level, another office may also assign symbols at the advanced level as original data.

Reclassified data is data changed due to a change in the classification schemes.

Various data is data changed due to an incidental reclassification of an individual document, such as the correction of a
mistake.

Deleted data is data which has to be deleted from the Master Classification Database, due to a change in allocation of
classification symbols to a document.

The indication of the different types of data is marked by the letters B for the basic or original data,
R for reclassified data, V for various incidental changes, and D for data to be deleted.

Position 40: Source of classification data

The following sources of classification data are foreseen:

       -     Intellectual classification by persons, value H for human generated data.

                      -                Machine classification by the propagation of earlier intellectual classification through the use of common
                                       priorities in the patent application. The value M is used in this case and will facilitate later corrections.

                      -                Classification symbols generated by software using automatic analysis of the content of the patent
                                       document. The letter G is used to indicate this source of generated data.


Positions 41-42: Generating Office

Since part of the original data in the advanced level and the reclassified data can be delivered by offices other than the
publishing office, the information source of such data is recorded by a field of two characters. The country or office code
CC, as defined by WIPO Standard ST.3, must be used.

7.                    Recording of complete IPC symbols

The full classification symbol must always be used when recording it on machine-readable records. The IPC section,
class and subclass should be provided for each group or subgroup classification, even if previously provided with
another group or subgroup classification in the same document.

See paragraph 2 of WIPO Standard ST.10/C for the recommended presentation of IPC classifications on machine
displays or in printed documents.

8.                    A schematic representation of the contents of the 50 positions is as follows:
                                                                            Main Group
