Identification des brevets offensifs par analyse sémantique Passe d’armes dans l’industrie pharmaceutique

To prevent competitors’ technological development, firms deploy offensive exclusionary patents strategies. Despite the importance of this practice, the literature still lacks data based empirical results. In this paper, I introduce a patent fence detection method based on NLP, complemented by an explorative bibliometric analysis of medical patents. The results demonstrate that companies rely on such a strategy to protect their most important and qualitative inventions.
