The United States Constitution explicitly grants Congress the power to create copyright law under Article 1, Section 8, Clause 8, known[1] as the Copyright Clause.

Copyright Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution. This is usually only for a limited time. The exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright is that copyright protects only the original expression of ideas, and not the underlying ideas themselves.[1][2]
