At the cutting edge of contemporary wealth creation people form self-governed communities of collaborative innovation in conditions of relative equipotency and produce resources with free access to all. The emergent intellectual commons have the potential to commonify intellectual production and distribution, unleash human creativity through collaboration and democratise innovation with wider positive effects for our societies. Contemporary intellectual property laws fail to address this potential. We are, therefore, in pressing need of an institutional alternative beyond the inherent limitations of intellectual property law. This book offers an overall analysis of the moral significance of the intellectual commons and outlines appropriate modes for their regulation. Its principal thesis is that our legal systems are in need of an independent body of law for the protection and promotion of the intellectual commons, in parallel to intellectual property law. In this context, the author of the book proposes the reconstruction of the doctrine of the public domain and the exceptions and limitations of exclusive intellectual property rights into an intellectual commons law, which will underpin a vibrant non-commercial zone of creativity and innovation alongside commodity markets enabled by intellectual property law.
