Book excerpt: Written by an experienced European Patent Attorney and scholar, this book sets out in detail the framework for protection of pharmaceutical innovation under the SPC Regulation. With a focus on both biotechnological innovation and secondary innovation, and through extensive reference to the case law, Ulla Klinge surveys the court’s evolving interpretation of legal and technical eligibility for this extended term of protection. This book provides clear and pragmatic tools to reflect and guide future practice, while offering key explanations and insights as to why and how technological developments challenge the legal SPC framework.
