    Abstract

    This paper presents an overview of co-patenting trends at the national and regional level in three technology fields (biotechnology, telecommunications and renewable energy), across regions in the OECD and emerging economies, from the late 1970s to the late 2000s. After a general introduction on regional patenting activities, inter-regional co-inventorship networks in the three selected technologies are built and analysed. Different behaviors and relative network positioning emerge, in terms of top patenting regions both across technological fields and over time. Co-patenting networks increase their density over time and they show preferential attachment properties, namely regions with a central position in an early phase of development of the network tend to maintain their positioning in the future. However, there are also windows of opportunity for new central nodes to emerge in the network. Evidence shows that the structure of the network evolves differently depending on technological field and that the role of spatial proximity and capability proximity is mixed in influencing co-inventorship patterns. Co-patenting networks include star players that establish connections regardless of the proximity of partners; but also several wellperforming actors that benefit from proximity or relative proximity of agents. Cet article analyse des réseaux de co-brevets parmi les régions des pays OCDE et des économies émergentes sélectionnées, dans trois secteurs technologiques (télécommunications, biotechnologie, énergie renouvelable) sur la période 1977-2007. Après une introduction générale sur la production de brevets à niveau régional, les réseaux inter-régionaux de co-brevets dans les trois technologies sont construits et analysés. Des comportements et des positionnements différents à niveau des régions émergent, dans la structure générale des réseaux analysés, selon la technologie et dans le temps. Les réseaux de co-brevets deviennent plus denses avec le temps et montrent la propriété de l’attachement préférentiel, soit les régions avec une position centrale dans le réseau au début tendent à la garder dans le temps. Toutefois, il existe des opportunités pour atteindre un positionnement central même pour les régions qui entrent dans le réseau dans des phases successives. Les données montrent comment la structure du réseau évolue avec des caractéristiques différentes selon la classe technologique et comment la proximité spatiale et la proximité des connaissances influencent l’évolution du phénomène de la co-invention des brevets : les réseaux d’excellence contiennent les acteurs leaders, qui établissent leurs collaborations innovantes sans tenir en compte la proximité géographique, ainsi que plusieurs acteurs performants qui bénéficient aussi de la proximité géographique relative avec autres agents.
