Thesis (Ph.D.)--Universitaet des Saarlandes (Germany), 1989.

This study deals with the problem of designing an automated system for classifying patent documents. First the efforts to apply automation to library classification schedules are reviewed. Since automation should provide better access to the body of technical knowledge, an automated patent system must be supported. To organize patent information, the International Patent Classification (IPC), which is accepted worldwide, is used. It is a one-dimensional hierarchic classification system. German patent documents are stored in a databank, PATDPA. PATDPA contains over 600,000 documents published since 1981.Subjects--Topical Terms:

520 $a This study deals with the problem of designing an automated system for classifying patent documents. First the efforts to apply automation to library classification schedules are reviewed. Since automation should provide better access to the body of technical knowledge, an automated patent system must be supported. To organize patent information, the International Patent Classification (IPC), which is accepted worldwide, is used. It is a one-dimensional hierarchic classification system. German patent documents are stored in a databank, PATDPA. PATDPA contains over 600,000 documents published since 1981.
520 $a Because of the special structure of patent applications (claims and description) the information directly related to the invention and the information additional and supplementary to the invention can be helpful for assigning class numbers through an automated system.
520 $a The German Patent Office makes available several aids to facilitate retrieval of information from classified documents. The Directory of Alphabetical Order Patent Descriptors and Index Terms is a list of the technical and common names of processes, machines, articles, composition of matter and other technological terms. This directory is used as a guide, rather than a precise locater. It should also be published in numerical order. Once the user learns the appropriate class with the approximate subclass of interest, then the directories in class number order can be helpful. These directories are used in the suggested automated classification system.
520 $a To obtain the innovative information and the concept of the patent application, its full text should be indexed. The two keyword indexing techniques, KWIT (keyword in title) and KWOT (keyword out of text), are suggested for indexing the title and full text to extract the terms representing the concept of the patent application. Through the occurrence analysis and weighting of these terms and with the help of the directories, the appropriate class numbers can be assigned. During this process the directories can be continuously completed and updated. This system can also improve and correct the classification of already classified documents.
520 $a The application of the International Patent Classification as an instrument for subject and class number search in the German patent databank PATDPA is illustrated. Suggestions are made for more effective retrieval in PATDPA. The above-mentioned processes and suggestions can bring the idea of thesaurus construction for each of the eight sections of the International Patent Classification into reality.
520 $a The suggested system simplifies the processing of patent documents, avoids mistakes and results in a well classified collection of patent documents which is obviously fundamental to determining patentability of a patent application. A uniform classification facilitates worldwide search into the existence of patent rights.
