This paper analyzes the regulatory framework in the public funds of the National Innovation System in Chile regarding diffusion and access to scientific and technological data. The results show several failures in the innovation regulatory framework. Concerning data diffusion, most funds do not clearly define who should carry out the diffusion activities, do not promote sufficiently the diffusion of non-confidential information and show little interest in defining and planning diffusion activities. Regarding data sharing, it should be clearly specified the means in which R+D+i data and process are to be delivered. In addition, open access requirements to researchers present serious deficiencies, while compliance of commitments, although show better results, should further improve.
