This book critically evaluates the EU regulatory framework for the liability of host Internet Service Providers (ISPs) for copyright and trade mark infringements and provides a cluster of novel recommendations for its improvement. The book recommends the imposition of a duty of care to host ISPs to curb the dissemination of unauthorised works and counterfeit goods, the ascription of a transparency obligation to host ISPs towards their users, and the establishment of a supervisory authority for host ISPs. Host ISPs have facilitated the dissemination of content amongst users and the purchase of goods online, enabling copyright holders and brand owners to attract a greater audience for their works and goods. However, their services have attracted a high number of copyright and trade mark violations, too. Neither Article 14 of the e-Commerce Directive nor Article 17 of the Copyright in the Digital Single Market Directive provide a solid response to the issue of host ISPs' liability. This book is a valuable resource for researchers in IT and IP law and offers a new perspective for resolving online IP disputes.
