The Copyright Act. Put simply â The Copyright Act 1994 is a set of guidelines that explains how published content can and can not be used. The general rule is: if it is published, it is copyright protected. The Copyright Act kicks in the moment you wish to copy, scan, save or share published material. As an honest, law abiding citizen, the important thing to know is how the law applies to you.
However, fair use is not an exception to copyright compliance so much as it is a âlegal defense.â That is, if you use a copyright protected work and the copyright owner claims copyright infringement, you may be able to assert a defense of fair use, which you would then have to prove. Section 107 of the United States Copyright Act lists four factors to help judges determine, and therefore to help you predict, when content usage may be considered âfair use.â
