两人牛牛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 of the Office of the Intellectual Property Enforcement Coordinator (). 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.
The Fair Use Index is designed to be user-friendly. For each decision, we have provided a brief summary of the facts, the relevant question(s) presented, and the court’s determination as to whether the contested use was fair. You may browse all of the cases, search for cases involving specific subject matter or categories of work, or review cases from specific courts. The Index ordinarily will reflect only the highest court decision issued in a case. It does not include the court opinions themselves. We have provided the full legal citation, however, allowing those who wish to read the actual decisions to access them through free online resources (such as Google Scholar and Justia), commercial databases (such as Westlaw and LEXIS), or the federal courts’ PACER electronic filing system, available at .
两人牛牛Although the Fair Use Index should prove helpful in understanding what courts have to date considered to be fair or not fair, it is not a substitute for legal advice. Fair use is a judge-created doctrine dating back to the nineteenth century and codified in the 1976 Copyright Act. Both the fact patterns and the legal application have evolved over time, and you should seek legal assistance as necessary and appropriate.
We hope you find the Fair Use Index a helpful resource. If you are concerned as to whether a particular use is fair, however, or believe that someone has made an unauthorized use of a copyrighted work in a manner that is not fair, it is best to consult an attorney.
Please note that the Copyright Office is unable to provide specific legal advice to individual members of the public about questions of fair use. See 37 C.F.R. 201.2(a)(3).
