Intellectual Liberty

Considering the steady increase in intellectual property rights in the last century, does it make sense to speak of 'user's rights' and can limitations on intellectual liberty be justified from a rights-based perspective? This book philosophically defends the importance of the public domain and user's rights through the use of natural-rights thought. Utilizing primarily the work of John Locke, it contends that considerations of natural justice and human freedom impose powerful constraints on the proper reach and substance of intellectual property rights, especially copyright.
