Title 17 of the Code of the United States gives copyright owners exclusive rights to reproduce, distribute, adapt, and publicly display or perform an original work. Copyright applies to published and unpublished literary, dramatic, musical, and artistic works. In the past, a copyright notice was necessary in order for a work to receive protection. This is no longer true. Copyright automatically applies to works in material form, including formats on the web. It does not, however, protect “ideas” and “concepts.”
Fair use is the doctorine that allows for reproduction of any portion of copyrighted materials for limited and transformative purposes, such as criticism, comment, parody, news reporting, scholarship, research, and teaching.
Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified in that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.
In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include-
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.
Purpose and Character of Use
A person using copyrighted materials must be able to demonstrate that the use is “transformative” and not merely derivative of the original work.
Nature of the Copyrighted Work
Certain characteristics and aspects of the original work are taken into consideration.
Amount
There are no exact amounts or measurements defined in copyright laws pertaining to the fair use of copyrighted materials. The quantity must be relative to the length of the original and the amount needed to convey the transformative idea or information.
Effect
Effect is very closely linked to the “purpose.”
