In this paper we present empirical evidence about some geographical characteristics of French prolific inventors through an analysis of French patents depos- its at the USPTO over a long time period (1975-2002). We found out that they are highly concentrated in the French space around three regional poles (Ile de France, Rhône- Alpes and PACA) and that inter-firms and geographic (regional) mobility is weak. Our estimates show that more mobile inventors (inter-firms) are more productive after con- trolling for effects of geomobility (with other control variables). By contrast, the more geomobile inventors are less productive after controlling for inter-firms’ mobility ef- fects. It means that the geographic dimension of mobility does not bring more effective- ness in the individual process of creativity. We must bear in mind there is a bias of si- multaneity within the relationship productivity/mobility that is not dealt with here.
