Private use is full of uncertainty both in theory and in application. Given the fact that the copying itself, whether in a private use context or a piracy context, is physically the same, it is very easy to confuse private copying with piracy. However, private use serves an important role not only relating to users' fundamental rights such as free speech and the right of autonomy and privacy, but also in contributing to the creative process by fostering creativity-relevant human capital. This book critically evaluates the legal treatment of private use under Chinese digital copyright law, which provides overprotection for Technological Protection Measures (TPMs) and abandons the private use limitation on digital copyright. It also examines the underlying causes and possible solutions.
