Fair use is a legal doctrine that says you can reuse copyright-protected material under certain circumstances without getting permission from the copyright owner. The four factors of fair use:

• The purpose and character of the use

• The nature of the work

• The amount and substantiality of the portion used in relation to the work as a whole

• The effect of the use on the market or potential market for the original work
