Abstract

The Patent Cooperation Treaty provides the possibility to seek patent rights in a large number of countries by filing a single international application with a single patent office. Since the mid-1980s, the patent cooperation treaty (PCT) procedure has become a popular method for filing patent applications, as is reflected in the substantial increase in PCT applications over the past 15 years. This paper analyses the impact of the PCT data on the European Patent Office (EPO) patent statistics, and explores methods to improve the timeliness of the EPO indicators by estimating the number of PCT applications which enter the EPO regional phase (see Annex A for details). This paper shows the following main impacts of PCT data in the EPO patent statistics: Including all EPO designated PCT applications data will overestimate the total number of EPO patent applications; and It will introduce a bias in favour of non-EPC countries (countries that are not signatory ... Répercussions du traité de coopération en matière de brevets sur les statistiques des brevets de l'oeb et possibilités d'amélioration de ces indicateurs Le Traité de coopération en matière de brevets permet, en déposant une seule demande internationale de brevet, d’obtenir la protection d’une invention conférée par un brevet dans un grand nombre de pays. Depuis le milieu des années 80, la procédure en vertu du traité de coopération en matière de brevets (PCT) connaît un succès grandissant, ainsi qu’en témoigne l’augmentation considérable du nombre de demandes PCT au cours des 15 dernières années. Le présent document analyse les répercussions des données du PCT sur les statistiques de l’Office européen des brevets (OEB) et étudie les possibilités d’améliorer la disponibilité de ces indicateurs pour les années récentes en effectuant des estimations du nombre de demandes PCT entrant dans la phase régionale de l’OEB (voir l’Annexe A pour plus de détails). Le présent document met en évidence les répercussions principales suivantes: Si l’on inclut les données relatives à la totalité des demandes PCT désignant ...
