I became aware of the importance of undertaking further research in the contractual analysis of databases during a master’s course in European Intellectual Property Law at Stockholm University. One of the key aspects of the LL.M. course syllabus was a focus on copyrights and database rights on the Internet. Problems can occur when companies and scientific institutions use and share “raw” data. These issues became more evident to me while working on a European Union (EU) funded project about cloud computing called OPTIMIS (Optimized Infrastructure Services) during my stay at the Institute for Legal Informatics (IRI) at the Leibniz Universität Hannover (LUH) in Germany. By a stroke of luck, I became heavily involved in the legal work that established what has turned out, for me, to be one of the most interesting topics on which to write a whole book. My personal experience of working with my colleagues from the OPTIMIS project has prompted me to pursue this field of research. I realized there was not much literature and material concerning the sui generis right as it applies to the field of cloud computing and Big Data.
