Copyright is generally interpreted that you can only copyright the part of a work that is original. So if you are granted a copyright for a work that includes unoriginal materials (which is virtually all works) you don't get a copyright on those parts of the work. For example if you write a song that uses familiar public domain motifs, you can get a copyright if you combine them or add to them in novel ways. You don't get a copyright on the pre-existing works. |
