1 INTRODUCTION General Remarks 1. The International Patent Classification (hereina fter referred to as fithe Classificationfl) is a system for the classification and retrieval of technical information contained in patent documents. This Catchword Index is intended to indicate the part or parts of the eighth edition of the Classification in which a technical subject is likely to be found. It must be stressed that this Index in no way replaces any part of the Classification, and must not be read as modifying the effect of anything in the latter. 2. The Index is based on catchwords chosen as indicative of technical subjects which may be of interest to a user of the Classification and for which more or less definite places in the Classification can be assigned. Since, as explained in the Guide to the Classification, contained in Volume 5 thereof, there are several factors to be considered when classifying technical subjects, it is not to be expected that all material that is relevant to a given query is to be found in one place, nor is it possible to provide a complete list of all places where information relevant to a given technical subject might be found, especia lly in respect of possible fields of use. Nevertheless, a search in the places indicated should disclose the greater part of the relevant material, and may also suggest other places in which to pursue the search. 3. In the course of the basic period of IPC reform (1999-2005), the Classification has been divided into the core and the advanced levels which constitute the eighth edition (2006) of the IPC (detailed information on IPC reform is available in the Guide to the IPC). This Catchword Index is intended for users of both the core and advanced levels. When the same entry in the Catchword Index is relevant for classification symbols in the core and advanced level, the classification symbol of the advanced level is given in round brackets after the corresponding classification symbol of the core level. Terms Used 4. The following terms are used in this Introduction: Catchwords = the words printed in capital letters, which are the primary constituents of this Index. Phrase = an indication, under a catchword, of a field of subject matter covered by, or associated with, the catchword. Classification symbols = the alphanumerical codes denoting a particular part of the Classification i.e., a subclass (sometimes a class) and (in many cases) a group or groups. Elaborations = the subdivisions of the Classification. Place = one, or a related series of subdivisions of the Classification, in which a technical subject can be classified, e.g., subclass, group.

2 Entry = a catchword or phrase, together with associated symbols of a place or places in the elaborations. Reference = placed after a catchword, or after a phrase, and indicating another catchword that may be relevant. Symbols Used 5. The following symbols are used in this Index: – (in a phrase) represents the catchword above it; = (always between brackets) introduces a synonym or a word or phrase indicating the sense in which a catchword is used, as in the following example: LIGHTERS (1) [= barges] B63B 35/28 (2) [= devices for igniting] see also IGNITING; * (placed after a Classification symbol, especi ally in the chemical field) indicates that the technical subject in question may be found also in other places in the same class; (See also paragraph 13, below.) ** see the Notes at the beginning of Section F, subsection fiEngines or Pumpsfl; + before a catchword or a phrase indicates that this catchword or phrase refers to an indexing code. It is important to note that indexing codes can only be used in association with relevant classification symbols and that not all industrial property offices assign indexing codes to patent documents because their application is not obligatory (see Chapter IX of the Guide to the IPC); [ ] should be ignored or interpreted as round brackets, depending on the context (the square brackets are intended for manipulation of the data by computer); ( ) (used for classification symbols) indicat es that the classification symbol is an advanced level classification symbol. Advice to Readers 6. The reader should be prepared to give some thought to the choice of appropriate catchwords. He should not expect to find a ready answer to every question or be satisfied with the first relevant answer found. 7. A reader seeking information on a particular subject is advised: (a) to consider the boundaries and essential features or limitations of the subject in question, bearing in mind, in particular, that things have both an intrinsic nature and a particular field of use (see paragraphs 85 to 88 of the Guide) and that different catchwords may be relevant for different points of view;

4 13. In the case of many chemical compounds, symbols of the elaborations are marked with an asterisk (*). This indicates that compounds of the kind in question may be found in a number of other places in the same class, in accordance with classification rules set out at the beginning of the class or subclass. The symbols given are those of the first place, or the most important places, where the substance may be found. 14. Entries which are worded in terms of particul ar applications (e.g., LINE(S) for fishing) are to be read as restricted to subject matter specially adapted to the stated applications. If no restriction is stated, the entry is to be read as covering the subject matter broadly. 15. In the case of entries for substances fiused infl particular fields of art (or with equivalent wording) it is to be understood that the substance per se is normally to be found in the appropriate general class, and the application class covers only the selection or manner of use of the substance for the particular application. 16. A reference following a phrase or entry relates only to that phrase or entry and not to any higher one, for example, under LATHE(S): fimaking LATHE(S) or like toolsfl, the reference fisee also TOOL(S)fl is relevant only to the entry fimaking LATHE(S) or like toolsfl. 17. In the majority of cases a word may be read as covering analogous subject matter, i.e., as though the words fior the likefl were added, provided that the extended meaning is not contrary to the wording at the place referred to in the entry. 18. In many cases the relevant subclass (or even class) is quoted without indicating any group, when it is considered that sufficient further guidance is given in that subclass, e.g. by the Subclass Index which may be provided in the elaborations (see paragraph 21(c) of the Guide). 19. In case of doubt as to the meaning of certain terms, the Glossary in the Guide may be found helpful. In addition, it should be mentioned that the term fivehiclefl is used in a very wide sense, covering ships, aircraft, sledges, etc., in addition to road and rail vehicles. 20. In compiling this book, care has been taken to avoid the use of trademarks as catchwords, but inadvertently some words which are used in one country or another as a trademark may have been included. 21. Anyone finding that there appears in this edition a trademark, for the use of which he has a right to protection, is invited to notify the International Bureau of WIPO. 22. The Internet version of the Catchword Index is available on the WIPO IPC Web site (www.wipo.int/classifications/ipc). 23.
