The term “Fintech” refers to the use of technology to automate various financial services, products, and operations. The aim of this paper is to examine the patents certificates to analyze technology trends and to forecast future developments related to the various aspects of Fintech. Through the network analysis of the patent dataset, we identified five relevant technological clusters that allowed us to detect the technological substrate underlying the corresponding cluster. The Bass diffusion model permitted the observation of the technological trajectories of each cluster outlining the diffusion patterns.
