Registering and Protecting your Copyrighted Works: Fair Use


The Fair Use Doctrine is a case law doctrine which says that it is not copyright infringement if the user is using the material for a "fair use". The only way to get an absolute answer as to whether a use is fair is to have it resolved in court. Judges use the following four factors to determine fair use:

  • the purpose and character of your use
  • the nature of the copyrighted work
  • the amount and substantiality of the portion taken, and
  • the effect of the use upon the potential market.
