Fair use is a legal doctrine that promotes freedom of expression by permitting the unlicensed use of copyright-protected works in certain circumstances.
The fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.
Four Factors are considered in determining whether the use made of a work in any particular case is a fair use.
The following "four factors" are used to analyze a fair use:
Factor 1: The Purpose and Character of the Use
Factor 2: The Nature of the Copyrighted Work
Factor 3: The Amount or Substantiality of the Portion Used
Factor 4: The Effect of the Use on the Potential Market for or Value of the Work
