In general, for works created on or after January 1, 1978, the term of copyright is the life of the author plus seventy years after the author’s death. If the work is a joint work with multiple authors, the term lasts for 70 years after the last surviving author’s death. For works made for hire and anonymous or pseudonymous works, the duration of copyright is 95 years from publication or 120 years from creation, whichever is shorter.
When the copyright term in a work expires, the work loses copyright protection and enters the public domain.
