Which of the following is NOT a factor used to evaluate Fair Use copyright?

In assessing Fair Use under copyright law, several specific factors are used to determine whether a particular use of a copyrighted work is permissible without permission from the copyright holder. The factors include the purpose and character of the use (such as whether it is for commercial or educational purposes), the effect of the use on the potential market for the original work, and the amount and substantiality of the portion used in relation to the copyrighted work as a whole.

Length of time the work has existed, however, is not a recognized factor in evaluating Fair Use. The Fair Use doctrine primarily focuses on how a work is used and its impact on the market, rather than when the work was created or has existed. Therefore, understanding the correct factors is crucial for navigating the complexities of copyright law and the Fair Use analysis.
