How long does a copyright last?

Duration of a Copyright

Generally speaking, the lifetime of the author plus 70 years.

However, for anything older than the 1970s, the rules get quite complicated.

Here is more information from the U.S. Copyright Office:

Works Originally Created on or after January 1, 1978

A work that is created (fixed in tangible form for the first time) on or after January 1, 1978, is automatically protected from the moment of its creation and is ordinarily given a term enduring for the author's life plus an additional 70 years after the author's death. In the case of "a joint work prepared by two or more authors who did not work for hire," the term lasts for 70 years after the last surviving author's death. For works made for hire, and for anonymous and pseudonymous works (unless the author's identity is revealed in Copyright Office records), the duration of copyright will be 95 years from publication or 120 years from creation, whichever is shorter.

Works Originally Created before January 1, 1978, But Not Published or Registered by That Date

These works have been automatically brought under the statute and are now given federal copyright protection. The duration of copyright in these works will generally be computed in the same way as for works created on or after January 1, 1978: the life-plus-70 or 95/120-year terms will apply to them as well. The law provides that in no case will the term of copyright for works in this category expire before December 31, 2002, and for works published on or before December 31, 2002, the term of copyright will not expire before December 31, 2047.

Works Originally Created and Published or Registered before January 1, 1978

Under the law in effect before 1978, copyright was secured either on the date a work was published with a copyright notice or on the date of registration if the work was registered in unpublished form. In either case, the copyright endured for a first term of 28 years from the date it was secured. During the last (28th) year of the first term, the copyright was eligible for renewal. The Copyright Act of 1976 extended the renewal term from 28 to 47 years for copyrights that were subsisting on January 1, 1978, or for pre-1978 copyrights restored under the Uruguay Round Agreements Act (URAA), making these works eligible for a total term of protection of 75 years. Public Law 105-298, enacted on October 27, 1998, further extended the renewal term of copyrights still subsisting on that date by an additional 20 years, providing for a renewal term of 67 years and a total term of protection of 95 years.

Public Law 102-307, enacted on June 26, 1992, amended the 1976 Copyright Act to provide for automatic renewal of the term of copyrights secured between January 1, 1964, and December 31, 1977. Although the renewal term is automatically provided, the Copyright Office does not issue a renewal certificate for these works unless a renewal application and fee are received and registered in the Copyright Office.

Public Law 102-307 makes renewal registration optional. Thus, filing for renewal registration is no longer required in order to extend the original 28-year copyright term to the full 95 years. However, some benefits accrue from making a renewal registration during the 28th year of the original term.

Additional information

Early works published without copyright or registration had no protection. If the registration was not renewed after 14 years, the copyright expired. Determination of which works in this period are still copyrighted is a complicated science. However, works published earlier than 1923 can be considered to have lapsed in the USA.

There are special considerations for certain types of works, such as "sound recordings" created prior to 1972. They are not covered by federal copyright at all. The 1909 statute did not include them as copyrightable, and the 1976 amendments did not give them retro-active federal copyright either!

Under 17 USC 301(c): "With respect to sound recordings fixed before February 15, 1972, any rights or remedies under the common law or statutes of any State shall not be annulled or limited by this title until February 15, 2067... Notwithstanding the provisions of section 303 [i.e., unpublished works don't expire until at least 2002], no sound recording fixed before February 15, 1972, shall be subject to copyright under this title before, on, or after February 15, 2067."
