This chapter deals with the special features of Spanish Law, in relation to the ownership of copyrights of university professors and staff of public research organizations. Together with the general regulation of salaried authors in the Intellectual Property Law, some special laws regulate the rights of these organizations on the results of scientific investigations developed by its personnel. It is doubtful whether it affects the ownership of copyright in accordance with the general regulation or repeals it. On the other hand, the reform of the Intellectual Property Law in 2014 has raised the question of whether the new wording of article 32 recognizes the ownership of copyrights to universities, by establishing the possibility of using the scientific creations by them, unless they are already holders of those rights. Keywords: Copyrights, university professors, thesis, universities and public research organizations, results of the investigation, salaried author.
