Abstract

Patent indicators – within the science and technology (S&T) context – are used to measure inventive performance, diffusion of knowledge and internationalisation of innovative activities – across countries, firms, industries, technology areas, etc. A common approach is to calculate patent indicators based on information (filings, grants, etc.) from a particular patent office. While the richness and strength of those indicators are broadly recognised, they are affected by “home” advantage bias – where proportionate to their inventive activity, domestic applicants tend to file more patents in their home country compared to foreign applicants. Patents taken in various countries to protect inventions can be linked together to build triadic patent families: a set of patents taken at the European Patent Office (EPO), the Japanese Patent Office (JPO), and the US Patent and Trademark Office (USPTO) that share one or more priorities. Patent families are derived from priority application ... Méthodologie relative aux familles triadiques de brevets Les indicateurs sur les brevets sont utilisés, dans le cadre de la science et de la technologie (S-T), pour mesurer les performances de l’innovation, la diffusion du savoir et la mondialisation des activités innovantes dans les pays, les entreprises, les industries ou les domaines technologiques. Une technique fréquemment utilisée pour leur comptage consiste à s’appuyer sur les informations (nombres de demandes, de délivrances, etc.) d’un office de brevets spécifique. Si la richesse et l’importance de ces indicateurs sont largement reconnues, leur fiabilité n’en est pas moins soumise à des biais liés à l’avantage national : proportionnellement à leurs activités de découverte, les demandeurs nationaux déposent généralement davantage de brevets dans leur pays d’origine que les demandeurs étrangers. Les brevets déposés dans divers pays pour protéger des inventions peuvent être regroupés en familles triadiques de brevets : un groupe de brevets déposés auprès de l’Office européen des ...
