For works created after January 1, 1978, copyright protection lasts for the life of the author plus an additional 70 years. For an anonymous work, a pseudonymous work or a work made for hire, the copyright endures for a term of 95 years from the year of its first publication or a term of 120 years from the year of its creation, whichever expires first. For works first published prior to 1978, the term will vary depending on several factors.
No renewal is required for works created on or after January 1, 1978. For works published or registered prior to January 1, 1978, renewal registration is optional after 28 years but does provide certain legal advantages.
If a copyrightable work is not a work for hire, an assignment of the copyright may be terminated within a 5-year period beginning 35 years after the initial grant. If the rights granted include the right to publish, then the assignment may be terminated 35 years after publication or 40 years after grant of publication right, whichever is first.
