Obtaining Copyright Protection
In the United States a copyright is obtained by the simple act of creating the original work. In other words, when an author writes down a song, makes a film, or develops a computer program, the author has the copyright. However, for a work that will be used commercially, it is advisable to register for a copyright with the US Copyright Office. A registered copyright is needed in order to bring legal action against someone who has used a work without permission.
