Copyright registrations do not occur in South Africa or in most other countries, since copyright is the one form of intellectual property that does not need to be registered. The United States is an exception to this, and in that country successful litigation depends on copyright being registered.
Unlike patents, trademarks or registered designs, copyright vests in the author of a work once the work has been created in a material form. It is normally sufficient to place a © with a name and the year at the foot of the article.
Copyright for written works remains the property of the owner for 50 years after his/her death, and computer programs for 50 years after they were first made known to the public.
