Right to Free Expression: Because the First Amendment prohibits Congress from making laws that abridge freedom of speech, federal statutes that implicate rights to free expression must have a buffer to safeguard constitutional rights. The federal copyright law is a good example. While copyright law provides a set of six exclusive, limited-time rights to copyright holders to serve as an incentive for them to create works, these rights are limited by the
fair use doctrine that is delineated in section 107 of the Copyright Act. The fair use doctrine guarantees individuals the right to use copyrighted materials, without seeking a copyright holder’s permission, for activities such as parody, satire, criticism, news reporting, teaching, scholarship, research, and transformative works. Fair use guarantees a "breathing space," or buffer, that helps to reconcile the tension that would otherwise exist between copyright law and the First Amendment's guarantee of freedom of expression.
