Copyright (or author’s right) is a legal term used to describe the rights that creators have over their literary and artistic works. Works covered by copyright range from books, music, paintings, sculpture, and films, to computer programs, databases, advertisements, maps, and technical drawings..
Firstly, copyright protection is automatic in all states party to the Berne Convention (refer to the question “Can I register copyright?”). Whilst there may be nuances to the particular national laws applicable in these states, in general there is a high degree of harmony. You can consult national laws and treaties using WIPO Lex. When we consider states that are not party to the Berne Convention, you must remember that copyright laws are territorial. In other words, they apply within the country in which they were passed. As such, if you wish to protect your work internationally, you must research and make sure that you comply with the relevant legal requirements in the country(ies) in which you wish your work to be protected.
Economic rights have a time limit, which can vary according to national law. In those countries which are members of the Berne Convention, the time limit should be equal to or longer than 50 years after the creator’s death. Longer periods of protection may however be provided at the national level. Contact your national IP office to find out more or visit WIPO Lex to consult national legislation.
