Evolution of a patent classification system

World Patent Information, 1983, vol. 5, issue 4, 213-218

Abstract: A 'meta-system' for guiding the change in existing patent information (classification) systems is described and its evolution over the last 20 years. The meta- system (if necessary with slight and obvious extension) is capable of handling all the kinds of search need that a patent information system is likely to be called upon to serve. It has as its main aim the handling of information on character, uses and applications of inventions with greater efficiency and precision than previously existing classifications and as a subordinate aim the provision of information on properties and utility which has not previously been attempted in a comprehensive manner.
