Copyright Duration and the Public Domain

By Hank FasthoffJuly 7, 2026

Before you use a photograph, a piece of music, a design, or a passage of text you didn't create, the first question is whether its copyright has expired. Copyright infringement generally imposes liability without proof that the user knew about the copyright. When statutory damages are available under Section 412, Section 504 permits an award of $750 to $30,000 per infringed work. A court may increase the award to $150,000 for willful infringement or reduce it to $200 when the infringer establishes innocent infringement.

Public domain status requires more than a publication date. The analysis depends on when the work was created, whether and when it was published, who authored it, and whether the owner complied with the renewal and notice requirements that applied at the time. Subject to the exceptions discussed below, a work created today by an individual author receives protection for the author's life plus 70 years. A work made for hire created and published today receives protection for 95 years from first publication.

Copyright duration affects both ownership and use. An owner needs to know when exclusive rights expire. A user who plans to rely on another person's work without a license needs the same date for every relevant copyright.

Works Created on or After January 1, 1978

For works created on or after January 1, 1978, Section 302 sets the copyright term according to authorship. A work by one individual author receives protection for the author's life plus 70 years. If a novelist publishes a book in 2026 and dies in 2060, the copyright runs through December 31, 2130, and the work enters the public domain on January 1, 2131.

A joint work receives protection for the life of the last surviving author plus 70 years. Section 101 defines a joint work as one prepared by two or more authors who intended their contributions to merge into inseparable or interdependent parts of a unitary whole.

A work made for hire receives protection for 95 years from first publication or 120 years from creation, whichever period expires first. A commissioned work qualifies only if it falls within one of the nine categories listed in Section 101 and the parties sign a written agreement stating that it's a work made for hire. Work created by an employee within the scope of employment qualifies under a separate branch of the definition. A corporate marketing brochure created and published in 2026 would enter the public domain on January 1, 2122.

The same 95-year or 120-year rule applies to anonymous and pseudonymous works. If an author's identity appears in the Copyright Office records before that term ends, the statute substitutes the applicable life-plus-70 term.

Works Published Before January 1, 1978

Many works first published in the United States before 1978 received an initial fixed term under the Copyright Act of 1909. That system used a 28-year initial term and a possible renewal term.

Congress extended the renewal term several times. The current maximum term for a qualifying renewed copyright is 95 years, consisting of the initial 28 years and a renewal term of 67 years.

Apart from the separate rules for sound recordings and certain foreign works, works first published in the United States before January 1, 1931, are in the public domain as of January 1, 2026. Works first published in 1930 entered the public domain that day. Works first published in 1931 will enter the public domain on January 1, 2027. The annual cycle continues through January 1, 2073, when the 95-year term for works first published in 1977 expires.

Renewal affected many works first published through 1963. If the owner failed to obtain a timely renewal, the copyright expired after its initial 28-year term. Congress made renewal automatic for copyrights secured from 1964 through 1977, so those works didn't lose protection through a failure to renew. The Copyright Office explains the distinction in Circular 15A.

The Copyright Notice Requirement

Publication without a proper copyright notice could place a work in the public domain under the law that applied before March 1, 1989. A proper notice generally identified the copyright, the year of first publication, and the copyright owner. For works published before January 1, 1978, authorized publication without notice generally placed the work in the public domain.

Section 405 governed omissions from copies distributed between January 1, 1978, and March 1, 1989. An omission didn't invalidate the copyright when notice appeared on all but a relatively small number of copies. The owner could also preserve the copyright by registering the work within five years after publication and making a reasonable effort to add notice to copies distributed after discovering the omission. The statute also excused an omission that violated a written condition of the owner's authorization requiring the copies to bear the notice.

Copyright notice has been optional for works published since March 1, 1989. A proper notice may affect remedies because Sections 401(d) and 402(d) restrict an infringer's ability to seek reduced damages based on innocent infringement.

Government Works

Under Section 105, copyright protection is unavailable for a work prepared by a federal officer or employee as part of that person's official duties. Federal agency reports and other works prepared by federal employees within their official duties generally enter the public domain upon creation.

The federal rule doesn't place every work associated with the government in the public domain. A federal agency may own copyrights transferred to it by a contractor or another copyright owner. Copyrighted photographs, illustrations, and other material owned by third parties and included in a federal publication retain their separate protection.

Section 105 applies to federal works. State and local governments may own federal copyrights in eligible material. The government edicts doctrine separately excludes legislative enactments, judicial opinions, administrative rulings, ordinances, and similar official legal materials from copyright protection at every level of government. Other state and local materials require an analysis of federal copyright law and any state law governing ownership or public access. The Copyright Office discusses these distinctions in Section 313.6(C) of the Compendium.

Sound Recordings Have a Different Timeline

Sound recordings and musical compositions are separate works with separate copyrights. A public domain composition may have a protected sound recording.

A musical composition first published in the United States before 1931 is in the public domain as of January 1, 2026. A later recording of that composition has its own term.

Sound recordings fixed on or after February 15, 1972, receive federal copyright protection under the ordinary duration rules. An individually authored recording generally receives a life-plus-70 term. A recording created as a work made for hire generally receives the 95-year or 120-year term.

Section 1401 establishes a separate schedule of federal remedies for sound recordings fixed before February 15, 1972. Chapter 14 provides federal remedies for those recordings without granting them ordinary federal copyright status. Recordings first published before 1923 entered the public domain on January 1, 2022. Recordings first published from 1923 through 1946 receive 95 years from publication followed by a transition period of five years. A recording first published in 1925 entered the public domain on January 1, 2026.

Recordings first published from 1947 through 1956 receive the 95-year period followed by a transition period of 15 years. Their public domain dates run from January 1, 2058, through January 1, 2067. The federal remedies for the remaining pre-1972 recordings end on February 15, 2067.

If you want to use a pre-1931 song in a commercial, you should confirm the status of both the composition and the selected recording. A recording by a 1940s orchestra may retain protection after the underlying composition enters the public domain.

Evaluating Public Domain Status

Confirming public domain status requires a review of the specific work. The review covers publication, renewal, adaptations, and source country.

• Publication date affects the term. Under Section 101, publication generally requires distribution of copies or phonorecords to the public or an offer to distribute them to a group for further distribution, public performance, or public display. A work created in 1925 and first published in 1960 has a different term from a work first published in 1925.
• Renewal records become relevant when a work first secured copyright from 1931 through 1963. Failure to renew a qualifying work ended protection after 28 years. Copyright Office records identify registered renewals.
• An original work and a subsequent adaptation have separate terms. A novel published in 1920 is in the public domain, while a film adaptation released in 1955 may retain protection. Copyright in the adaptation covers the expression added by the filmmakers.
• Source country affects the analysis. Section 104A restored U.S. copyright in certain foreign works that entered the U.S. public domain through a failure to comply with prior formalities while remaining protected in their source countries. A foreign work's earlier public domain status in the United States therefore may provide an incomplete answer.

Practical Recommendations

If your business uses historical texts, photographs, designs, or music, you should document the public domain basis for each work. The file should identify the exact version used, relevant creation and publication dates, author information, renewal and notice records, source country, and any subsequent adaptation or recording.

A mistaken public domain conclusion may result in infringement liability. Statutory damages depend on timely registration and the other conditions in Section 412. When those damages are available, Section 504 authorizes $750 to $30,000 per work, up to $150,000 for willful infringement, and a possible reduction to $200 for innocent infringement.

If your business owns works first published before 1978, you should confirm whether renewal was required and completed. A work first published through 1963 may have entered the public domain after 28 years if the owner failed to renew it. Foreign works require a separate restoration analysis under Section 104A.

For music, the composition and the sound recording each have their own term, and each requires its own review. A recording of a public domain composition first published in 1945 remains within the Section 1401 period of federal remedies through December 31, 2045, and enters the public domain on January 1, 2046.

If you're acquiring a content library, you should conduct a duration analysis for each work. Expired copyrights, missed renewals, defective notice, restored foreign copyrights, protected adaptations, and separately protected recordings affect the assets' value and the buyer's ability to offer exclusive rights.
