Welcome to the U.S. Copyright Office Fair Use Index. This Fair Use Index is a project undertaken by the Office of the Register in support of the 2013 Joint Strategic Plan on Intellectual Property Enforcement of the Office of the Intellectual Property Enforcement Coordinator (IPEC). Fair use is a longstanding and vital aspect of American copyright law. The goal of the Index is to make the principles and application of fair use more accessible and understandable to the public by presenting a searchable database of court opinions, including by category and type of use (e.g., music, internet/digitization, parody).

The Fair Use Index tracks a variety of judicial decisions to help both lawyers and non-lawyers better understand the types of uses courts have previously determined to be fair—or not fair. The decisions span multiple federal jurisdictions, including the U.S. Supreme Court, circuit courts of appeal, and district courts. Please note that while the Index incorporates a broad selection of cases, it does not include all judicial opinions on fair use. The Copyright Office will update and expand the Index periodically.
