Fair use is a legal doctrine that promotes freedom of expression by permitting the unlicensed use of copyright-protected works in certain circumstances. Section 107 of the Copyright Act used the following four factors in evaluating a question of fair use:
Factor 1: Purpose and Character of the Use:
- Work can be for education, scholarship, research, news reporting, criticism or commentary purposes.
- Work used for commercial purposes is discouraged.
Factor 2: Nature of the Original Work
- Is it has been published or not?
- If it is not published, there is less likely a chance of it being considered fair use.
- Is the nature of the work more factual or creative?
- Generally copyright law does not protect general knowledge (facts and data)
Factor 3: Amount and Substantiality of the Portion Used
- Smaller amounts are better.
- Keep in mind that the amount accepted under fair use is proportional to the length of the work.
- Sustainability: Whether or nor you use the heart of the work or a part that is peripheral.
Factor 4: Effect of the Use on the Potential Market for or Value of the Source Work
- Is the use in question substituting for a sale the sources's owner would otherwise make? Either to the person making the proposed use, or to others?

What is Copyright:
Under U.S. law, copyright protects creative works. It covers both published and unpublished works.
Examples of Creative Works:
- musical compositions,
- sound recordings,
- architectural works
Copyright does not protect facts, ideas, or titles. Works that are created by the government are not protected.
Copyright owners have six specific rights under the law:
- To make copies of the work.
- To make derivatives of the work.
- To distribute copies of the work.
- To publicly perform the work.
- To publicly display the work.
- To perform the work publicly through digital audio transmission.
Please note: All creative works in the US are now protected by copyright automatically as soon as they are created. They are not required to have the copyright symbol.
