    Abstract
    Describes and evaluates methods for automatically isolating and extracting biliographic references from the full texts of patents, designed to facilitate the work of patent examiners who currently perform this task manually. These references include citations both to patents and to other bibliographic sources. Notes that patents are unusual as citing documents in that the citations occur maily in the body of the text, rather than as footnotes or in separate sections. Describes the natural language processing technique of template mining used to extract data directly from the text where either the data or the text surrounding the data form recognizable patterns. When text matches a template, the system extracts data according to instructions associated with that template. Examines the sub languages of citations and the development of templates for the extraction of citations to patent. Reports results of running 2 reference extraction systems against a sample of 100 European Patent Office patent documents, with recall and prescision data for patent and non patent citations, and concludes with suggestions for future improvements

    Abstract
    Reviews the PowerSearch multifile searching software introduced by ORBIT Search Service as it is used for searching patent databases. Looks at its useful features: deduping, patent family grouping, merge, and virtual file merging. Looks at some possible improvements to both PowerSearch itself and to the ORBIT system to accomodate PowerSearch

    Abstract
    Describes the main features of the 6th ed. of the International Patent Classification (IPC) and its differences from the 5th ed. A substantial difference is the increased number of hybrid systems whose introduction into the Classification is becoming one of the leading trends in the revision of the IPC. Outlines the decisions of the Committee of Experts of the IPC union concerning the terminology used in the IPC, the presentation of notes and the application of indexing schemes. Considers the future developments of the IPC

    Abstract
    The author, former head of information and documentation at the German patent office, recalls more than 30 years of international cooperation in the classifying and indexing of patent documents. Reviews the work of the former ICEREPAT (International Cooperation in Information Retrieval among Examining Patent Offices) which produced coordinate indexing term lists. Describes the development of the IPC which produced a purely hierarchical classification with function oriented and application oriented entries. Completion of the IPC as a basic search tool was greeted with satisfaction by the patent world. Revised versions of IPC are issued every 5 years in English and in French. Outlines the problems still associated with the searching of patent documents

    Abstract
    Discusses the implications for users of patent information of the decision by the European Patent Office (EPO) to follow the US by offering the full text of patents, free, via the Internet. This poses a threat to the traditional vendors and could result in the loss of sophisticated searching should they withdraw from the patent information market. While it is possible that the Internet and online vendors could supply complementary levels of service, high quality patent abstracting and indexing is expensive and vendors are under pressure to reduce prices. Describes the implementation of the EPO project and the impact on MicroPatent of IBM's Web based patent service

    Abstract
    Describes the European Classification System (ECLA) used by search examiners at the General Directorate 1 (DG 1) of the European Patent Office in The Hague, Netherlands, for classifying patent applications for publication, new patent documents and non-patent literature for addition to the systematic search documentation. ECLA is an internal classification tool developed on the basis of the International Patent Classification (IPC) but with further subdivisions and better adaptation to the different technical fields. In order to overcome the limitations of a classification system, secondary systems are also in use or under development. One such system is the ICO (In Computer Only) system which offers online only light indexing schenmes for the identification of additional information contained in patent documents

    Abstract
    Gives details of patent information available on the Internet. The patent data available is fairly basic and unlikely to be of interest to the 'professional' patent searcher but, nevertheless, there is sufficient searchable material available to answer many of the questions raised by the occasional searcher looking for technical information in broad subject areas

    Abstract
    STN Easy is a new graphic user interface for the WWW access to over 20 major online databases in business, science, technology and patents. Patent information is available from a number of Web sites but argues that STN Easy offers extensive coverage combined with both searching sophistication and operational simplicity. Concludes that STN Easy is not a replacement for nor competitor to STN, but provides a complementary means of retrieving patent information for end users or others who do not need the full power of a command language
