United States federal Copyright law grants the creator of an original work  a number of exclusive rights. Copyright protection assumes three elements: the work is original, minimally creative, and fixed in a tangible format.

These exclusive rights are not absolute, and they may be unbundled and transferred to someone else: for example, an author may sign over book printing and distribution rights to a publisher. The rights are also limited in duration  and are subject to a number of other exceptions.

A brief discussion of one of these limitations follows.
