The Copyright Term Extension Act of 1998, often called the Sonny Bono Copyright Term Extension Act, added 20 years to almost every copyright term in the United States. For works created by individual authors, protection now runs for the author’s life plus 70 years. For works owned by corporations from the start, the ceiling is 95 years from publication or 120 years from creation, whichever comes first. Critics nicknamed it the “Mickey Mouse Protection Act” because Disney lobbied heavily to keep its earliest cartoon characters out of the public domain, and one stated goal was to bring U.S. terms into line with the European Union’s life-plus-70 standard.
How Long Copyright Lasts for Individual Authors
If you create an original work on or after January 1, 1978, your copyright lasts for your entire life plus 70 years after your death.1Office of the Law Revision Counsel. 17 U.S.C. 302 – Duration of Copyright: Works Created on or After January 1, 1978 Before the Sonny Bono Act, that figure was life plus 50 years. The extra two decades mean heirs and estates can control licensing, reproductions, and adaptations well into the next century.
For works with more than one author, the clock starts from the death of the last surviving co-author, and copyright runs 70 years past that date.1Office of the Law Revision Counsel. 17 U.S.C. 302 – Duration of Copyright: Works Created on or After January 1, 1978 A collaboration between a 30-year-old and a 60-year-old will therefore stay protected far longer than either author could have secured alone. This joint-work rule does not apply when the authors created the work as employees under a work-for-hire arrangement.
How Long Corporate, Work-for-Hire, and Anonymous Works Last
When a business owns the copyright from the start, the life-plus-70 formula does not apply. The term is 95 years from first publication or 120 years from creation, whichever expires sooner.1Office of the Law Revision Counsel. 17 U.S.C. 302 – Duration of Copyright: Works Created on or After January 1, 1978 The same formula covers anonymous and pseudonymous works when the real author has not been identified in Copyright Office records.
A creation qualifies as a “work made for hire” in two situations. One is straightforward: an employee produces something within the scope of their job. The other is narrower and requires a signed written agreement, and only certain commissioned categories qualify, including contributions to a collective work, translations, parts of a film, instructional texts, and compilations.2Office of the Law Revision Counsel. 17 U.S. Code 101 – Definitions If you are a freelancer and your contract does not fit one of those categories, the work is not made for hire regardless of what the paperwork says, and the life-plus-70 rule applies to you personally.
The distinction matters. Studios rely on the 95-year window to control characters, film libraries, and software for nearly a century after release. If a work was misclassified as work for hire when it was actually a personal creation, the entire duration calculation shifts, and the original creator may have termination rights the company assumed did not exist.
What the Act Did to Older Works Still Under Copyright
The Sonny Bono Act did not only affect future works. It reached back and extended anything still under copyright on October 27, 1998, when the law took effect. Under the previous system, works published between 1923 and 1977 could receive a maximum of 75 years of protection if their copyrights had been properly renewed. The 1998 law added 20 years, pushing the ceiling to 95 years from the date copyright was originally secured.3Office of the Law Revision Counsel. 17 U.S.C. Chapter 3 – Duration of Copyright – Section 304
The extension only rescued works still protected when the law passed. Congress did not revive lapsed copyrights. If a work had already fallen into the public domain before October 1998, the Sonny Bono Act did nothing for it. That is why everything published before 1923 has been in the public domain for decades, while works from 1923 onward gained the extra 20 years.
The Pre-1964 Renewal Trap
The 95-year extension only helps works whose copyright owners cleared every procedural hurdle. For works published between 1923 and 1963, that included a mandatory renewal filing with the Copyright Office during the 28th year of the original term. Miss that window, and the copyright died permanently at the end of year 28.4U.S. Copyright Office. How to Investigate the Copyright Status of a Work (Circular 22)
Many copyright holders did miss it. Studies of renewal records suggest a large majority of works from this era were never renewed, putting them into the public domain long before their 95-year term would have expired. If you are trying to figure out whether a specific book, film, or song from the 1920s through early 1960s is still protected, the first question is not “has 95 years passed?” but “was the copyright actually renewed?”
A 1992 amendment changed the rules for later works: for works published between 1964 and 1977, Congress made renewal automatic, and no filing was required for the copyright to continue into its extended term.5Office of the Law Revision Counsel. 17 U.S.C. 304 – Duration of Copyright: Subsisting Copyrights The result is a sharp divide. Pre-1964 works are a minefield of lapsed copyrights. Works from 1964 through 1977 almost certainly received the full 95-year term.
When Copyrights Expire and What Enters the Public Domain
Every copyright term in the United States runs through December 31 of the year it would otherwise expire. You never need to pin down the exact date of an author’s death or a work’s first publication. If an author died on March 15, 1956, and the term is life plus 70 years, protection expires on December 31, 2026, and the work enters the public domain on January 1, 2027.6Office of the Law Revision Counsel. 17 U.S.C. 305 – Duration of Copyright: Terminal Date The same rule applies to the 95-year term for older published works: a 1930 publication runs through December 31, 2025, and enters the public domain on January 1, 2026.
Since 2019, when 1923 works first began entering the public domain under the 95-year rule, each New Year’s Day has opened another year of material. The full decade of the 1920s cleared by 2025. On January 1, 2026, works first published in 1930 whose copyrights were properly maintained became free for anyone to copy, adapt, perform, or build upon. The year’s crop includes William Faulkner’s As I Lay Dying, Dashiell Hammett’s The Maltese Falcon, the first four Nancy Drew mysteries, All Quiet on the Western Front, the Marx Brothers’ Animal Crackers, and songs including Georgia on My Mind and the Gershwins’ I Got Rhythm.
Only the specific 1930 versions are free. Later editions, adaptations, or revised versions published in subsequent years remain protected under their own separate copyrights.
The Constitutional Challenge in Eldred v. Ashcroft
The retroactive extension drew an immediate legal challenge. Critics argued that the Constitution’s Copyright Clause authorizes protection only for “limited Times,” and that repeatedly extending existing copyrights made those times effectively unlimited. The case reached the Supreme Court as Eldred v. Ashcroft in 2003.
The Court upheld the law. It found that Congress acted within its authority under the Copyright Clause by extending existing and future copyrights in parallel, and that the extension did not violate the First Amendment.7Legal Information Institute. Eldred v. Ashcroft (01-618) 537 U.S. 186 (2003) The majority reasoned that Congress had extended existing copyright terms many times throughout history and that nothing in the Constitution categorically bars it from doing so again. As long as Congress sets a finite term, even a very long one, it satisfies the “limited Times” requirement.
Whether Congress will extend terms again remains an open question. The Sonny Bono Act was widely seen as a response to Disney’s push to keep Steamboat Willie protected. That film’s copyright expired on January 1, 2024, without any further extension.
Termination Rights the Act Preserved for Authors and Heirs
The Act did not just benefit the corporations and estates that already controlled copyrights. It also created a second chance for authors and their families to reclaim rights they had signed away decades earlier.
Grants Signed On or After January 1, 1978
If you transferred or licensed your copyright on or after January 1, 1978, you can terminate that deal during a five-year window that opens 35 years after you signed the agreement. If the grant involved publication rights specifically, the window opens either 35 years after publication or 40 years after the grant was signed, whichever comes first.8Office of the Law Revision Counsel. 17 U.S. Code 203 – Termination of Transfers and Licenses Granted by the Author
To exercise the right, you must serve written notice stating the effective termination date. That notice must arrive no fewer than 2 and no more than 10 years before the chosen date, and a copy must be recorded with the Copyright Office before termination takes effect. For joint works, a majority of the authors who signed the original grant must agree to terminate.8Office of the Law Revision Counsel. 17 U.S. Code 203 – Termination of Transfers and Licenses Granted by the Author
A wrinkle worth knowing: if a derivative work was created before termination, the grantee can keep using that specific derivative under the original terms, but they cannot create new derivatives after the termination date. A publisher who adapted your novel into a screenplay before termination can continue distributing that screenplay. They cannot commission a sequel based on your novel without a new agreement.
Reclaiming Rights During the Extra 20 Years
For older works still in their renewal term when the Sonny Bono Act took effect, a separate termination right applies to the 20 extra years Congress added. If the author or heirs missed the earlier termination window under the renewal-term rules, the Act opened a new five-year window beginning 75 years after the copyright was originally secured.5Office of the Law Revision Counsel. 17 U.S.C. 304 – Duration of Copyright: Subsisting Copyrights The same notice requirements apply.
This provision matters most for the families of authors who signed away rights in the mid-twentieth century. A songwriter’s heirs who missed the earlier termination deadline can still reclaim the copyright for the final stretch of the 95-year term. These termination rights cannot be waived by contract. Even if the original agreement says “irrevocable,” the statute overrides that language.
Who Can Terminate After the Author Dies
When the author is no longer alive, termination rights pass through a fixed statutory hierarchy. A surviving spouse owns the entire termination interest unless there are living children or grandchildren, in which case the spouse owns half. Children and grandchildren share the other half, divided by family branch. If no spouse, children, or grandchildren survive, the right passes to the author’s executor or personal representative.8Office of the Law Revision Counsel. 17 U.S. Code 203 – Termination of Transfers and Licenses Granted by the Author The rules are rigid, and termination rights cannot be reassigned by will to someone outside this hierarchy.
