Certain sections of the 1976 Copyright act limit the scope of copyright. In some instances, your rights are limited by a “compulsory license”, which permits certain limited uses of copyrighted works upon payment of specified royalties and compliance with statutory conditions. Another important limitation is the doctrine of “fair use” (Section 107), which holds that certain uses of copyrighted works do not infringe on the rights of the copyright holder. “Fair use” is usually invoked for purposes of criticism, comment, news reporting, and education (teaching, scholarship and research). There are four main points taken into consideration when determining “fair use”:
- the purpose and character of the use (e.g., is the work being used for non-profit or educational purposes, or is it being used commercially?)
- the nature of the copyrighted work (e.g., is it amenable to educational, critical, or news-reporting use, or even parody?)
- the amount and substantiality of the the work being used (e.g., is the whole work reproduced, or only a portion? Is it a black and white photocopy of a color painting, or a high quality full size and color reproduction?)
- the effect of the use upon potential market value of the work (e.g., will the derivative version eclipse or reduce the value of the original, or will it raise the original's value?)
