The OECD Technology Concordance (OTC): Patents by Industry of Manufacture and Sector of Use


  • Daniel K. N. Johnson


While patent data are now readily available for most nations, these data are still of minimal use for economic analysis due to their mode of presentation. Patents are recorded for administrative purposes using the International Patent Classification (IPC) system, which categorises inventions by product or process. Instead, most economic researchers and analysts are interested in the particular sectors of the economy responsible for the invention or its subsequent use. The OECD Technology Concordance (OTC) presented here, like its predecessor the Yale Technology Concordance, is a tool that bridges definitions, allowing researchers to transform IPC-based patent data into patent counts by sector of the economy. This paper presents the methodology, some sample output and empirical tests of the method. It should be noted that the methodological work on the distribution of patent data by industry at the OECD is an early stage and further improvement of the OTC is expected in the ... Il est facile aujourd’hui de se procurer des données sur les brevets dans la plupart des pays, mais leur mode de présentation leur enlève presque toute pertinence pour l’analyse économique. Les brevets sont enregistrés à des fins administratives selon le système de Classification internationale des brevets (CIB), dans lequel les inventions sont regroupées par produits ou procédés. Par contre, la plupart des données et des analyses économiques portent sur les secteurs de l’économie à l’origine d’une invention ou sur ceux qui en sont les utilisateurs. A l’instar du Technology Concordance de Yale en usage avant lui, le Technology Concordance de l’OCDE (OTC) présenté ici est un outil qui établit un lien entre les deux logiques et permet aux chercheurs, à partir des données sur les brevets classées selon le système CIB, de répertorier les brevets par secteur économique. On trouvera dans le présent document, la méthodologie, quelques exemples d’application, et des essais empiriques de la ...
