However, there has been little comparative study of sui generis intellectual property protection that would evaluate the effectiveness of sui generis regimes and estimate whether the goals pursued by the legislators introducing sui generis regimes for different kinds of subject matter have been achieved. Thus, this book is aimed at filling this gap and contributing to a better understanding of sui generis intellectual property rights.
