These include computer programs and computer generated works, satellite broadcasts, cable programmes and multimedia. The essence of copyright is the protection of the expression of an idea. Copyright does not protect bare ideas. Unlike protection conferred by patents and registered designs, copyright automatically comes into existence upon creation of a work without the need to go through a registration procedure. However, it is desirable to make it clear that copyright is claimed by including a copyright notice on the work.
Literary works are works other than dramatic or musical works which are written, spoken or sung.
These include tables or compilations and computer programs. Under the Act, express protection is given to computer programs as literary works. Similarly, databases and multimedia productions are protected as literary works. Further additions include a new category for cable programmes, and the expansion of the broadcasting category to include foreign broadcasts and broadcasts from satellites received in New Zealand. Video cassettes and disks are protected as films.
