- Copyrights Copyright laws protect written or artistic expressions fixed in a tangible medium – novels, poems, songs or movies. A copyright protects the expression of an idea, but not the idea itself. The owner of a copyrighted work has the right to reproduce it, to make derivative works from it (such as a movie based on a book), or to sell, perform or display the work to the public. You don’t need to register your material to hold a copyright, but registration is a prerequisite if you decide to sue for copyright infringement. A copyright lasts for the life of the author plus another 50 years.
