How Long Copyright Lasts — and What Happens After

§ 01The Basic Clock

Copyright begins the moment a work is fixed in a tangible form — a sentence saved, a photograph taken, a song recorded. In most countries, protection then runs for the life of the author plus a further period after death, commonly 70 years. That 70-year post-mortem term is standard across the European Union, the United Kingdom, the United States, and many other jurisdictions. Some countries use 50 years after death, which remains the Berne Convention minimum. A handful use longer terms for specific categories of work.

What "life plus 70" actually means in practice: if a novelist dies in 2010, her novels remain under copyright until 31 December 2080 in most jurisdictions that follow this rule — the term typically runs to the end of the calendar year in which it expires, not to the precise anniversary of death. That end-of-year rounding is small but matters when you're calculating whether something has cleared.

Corporate and anonymous works complicate the calculation. In the United States, works made for hire — created by an employee within the scope of employment, or commissioned under a specific written agreement — follow a different clock entirely: 95 years from publication, or 120 years from creation, whichever expires first. Anonymous and pseudonymous works follow similar rules. The EU and UK use comparable frameworks for works where the author is unknown.

§ 02The United States Complication

American copyright history is particularly tangled, because Congress has extended terms multiple times. Works published in the US before 1930 are now in the public domain. Works published between 1930 and 1977 require careful case-by-case checking: publication date, whether copyright was registered, whether it was renewed, and whether the work was published with proper notice all affect the outcome. This is not a simple sliding scale — it's a decision tree, and getting it wrong has consequences.

The Copyright Act of 1976 fundamentally overhauled US law, shifting from a registration-and-renewal system to the automatic, life-plus model aligned with international norms. Works created from 1 January 1978 onward in the US follow the life-plus-70 rule. Older works, depending on exactly when and how they were published, can have terms ranging from already-expired to surprisingly long.

One shorthand worth knowing: in the US, a new tranche of pre-1978 works enters the public domain on 1 January each year, as the oldest still-protected works tick past their term. On 1 January 2025, works published in 1929 joined the US public domain. That annual release makes the first day of each new year a quiet event in libraries, archives, and academic publishing.

§ 03After the Clock Stops

When copyright expires, the work enters the public domain — no permission required, no licence fee, no restriction. Anyone can reprint, adapt, translate, perform, or build on it freely. This is not a loophole or a grey area; it is the designed outcome of the copyright bargain. Creators get a period of exclusive control; the public eventually gets the work back.

The catch is that public domain status applies to the original work, not necessarily to every version of it. A new translation of a public-domain novel is itself a new copyrighted work. A scholarly edition with original critical apparatus carries its own protection. A digitised scan of a public-domain painting may or may not attract rights depending on jurisdiction — UK and EU courts have reached different conclusions on this point, and US courts have generally declined to grant copyright in a faithful mechanical reproduction. Read the fine print on any archive or database before assuming the digital file is as free as the underlying work.

Moral rights, where they exist in law, can also survive copyright expiration in some jurisdictions. France, for instance, recognises perpetual moral rights — meaning an author's heirs can still object to derogatory treatment of a work even after the economic rights have expired. These rights don't prevent reproduction, but they can constrain how a work is used.

Related rights add another layer: a sound recording carries its own separate term, distinct from the underlying musical composition. In the EU, sound recordings enjoy 70 years of protection from the date of publication. A symphony composed in 1900 is long in the public domain; a recording of that symphony made in 1970 may still be protected.

§ 04What to Do With the Uncertainty

If you're relying on a work being in the public domain, verify rather than assume. For US works, the Cornell Copyright Information Center publishes a widely-used chart mapping publication date to copyright status. For works outside the US, identify the author's country and death date, then apply that country's term. When a work has multiple contributors — and different death dates — the term usually runs from the last surviving author's death.

Copyright's duration is a design feature, not an accident. The years matter, and so does the arithmetic.
