This book provides a comprehensive examination of data sharing within the EU, exploring the regulatory challenges and opportunities created by EU frameworks and policies. As data becomes a critical resource across sectors, EU regulators, policymakers, and scholars face the urgent task of crafting frameworks that support data sharing while ensuring fairness, competition, and protection of personal data. Through its chapters, the book adopts a holistic approach, analyzing data sharing from the perspectives of EU law, intellectual property, competition law, data protection, and governance. It addresses the impact of recent EU legislation—including the Digital Markets Act (DMA), Digital Services Act (DSA), Data Governance Act, and Data Act—on enabling or limiting data-sharing practices, particularly in the private sector. Each chapter offers policy recommendations and insights, collectively building a robust theoretical framework for responsible data sharing. This book serves as a valuable resource for researchers, practitioners, and students of EU law, competition law, data protection, intellectual property, and governance, offering timely insights and a nuanced exploration of the evolving EU data-sharing landscape.
