Copyright Act — authorship, exclusive rights and fair use (17 U.S.C. chapter 1)

AI-use reference. Existing law; no general AI exemption. Applies to: Copying, adapting, distributing and using protected works, including AI inputs, training, retrieval and outputs where statutory rights are implicated. Requirements or purpose: Check ownership, permission, licenses and applicable exceptions. Section 107 requires a context-specific four-factor fair-use analysis; an educational or governmental purpose alone does not decide it. Limits: The collection does not decide whether any identified model training or output infringes. Section 105 addresses federal government works and is not a blanket public-domain rule for city or school material.
