In this volume, general aspects of biopatent law will be discussed. This involves questions of patentability, including ethical issues and issues of technicality, as well as questions of patent exhaustion in cases were reproducible subject matter, like cells or seeds, is protected. Moreover, active and passive patent strategies are addressed. Further, insight will be given into patent lifetime management and additional protective measures, like supplementary protection certificates and data exclusivity. Here, strategies are discussed how market exclusivity can be extended as long as possible, which is particularly important for biopharmaceutical drugs, which create high R&D costs.
