In U.S. copyright law, “copyright reversion” usually means statutory termination of a copyright transfer or license. In qualifying cases, an author or the author’s successors can end an exclusive or nonexclusive grant after a statutory period, even if the contract says the grant is irrevocable. Eligibility, work-made-for-hire status, grant dates, publication facts, successor interests, notice service and recordation all determine whether termination is available.

This is a U.S. federal-law explanation, not a universal rule and not a determination about any particular contract or game. The first task is to identify exactly who granted which rights, when the grant was signed, when copyright was secured or the work was published, and whether the work was made for hire.

What “copyright reversion” means under U.S. law

The Copyright Act does not generally use “reversion” as the operative procedure. It provides statutory termination of certain transfers and licenses. The Copyright Office explains that authors or their heirs may, under specified circumstances, terminate an exclusive or nonexclusive grant of copyright or of any individual copyright right.

Termination is different from a contract’s ordinary expiration, a royalty clause, or a negotiation with a publisher or game company. It is a statutory power with its own eligibility rules and deadlines. A contract term that purports to waive the termination right generally cannot defeat a qualifying post-1977 author termination under §203, but that does not make every assignment terminable.

#1 Best Overall

The analysis is document-specific. A single project can involve several grants, contributors, territories, media and derivative works, each with a different result.

Choose the correct statutory route first

The execution date of the grant and the date the copyright was secured usually determine which provision to examine. Publication rights and work-made-for-hire status can change the calculation or eliminate eligibility.

Provision General scope Timing and status
§203 Author-executed grants made on or after January 1, 1978, for works other than works made for hire. The Copyright Office also describes qualifying “gap grants” in its guidance. Notice normally must be served 2–10 years before the chosen effective date. The effective date generally cannot precede 35 years after execution, while notice may be serviceable no earlier than 25 years after the grant. Publication grants use a different publication-related calculation; use the Office’s timing tables and the actual agreement.
§304(c) Certain grants executed before January 1, 1978, concerning copyrights secured before January 1, 1978. Uses a separate five-year termination period tied to the older copyright’s renewal and extension history.
§304(d) A narrow historical category involving qualifying copyrights secured from January 1, 1923, through October 26, 1939, and older grants. The Copyright Office states that the final date to serve a §304(d) notice was October 26, 2017, and the final date to record one was October 26, 2019.

These are legal periods, not success-rate statistics. A date that looks simple in isolation can change after checking the signed grant, publication history, renewal record and any later transfer.

How §203 timing works for post-1977 grants

Start with the execution date

For an author’s qualifying grant executed on or after January 1, 1978, §203 generally provides a termination window. The usual rule is that termination becomes effective 35 years after execution. If the grant includes the right of publication, a publication-related formula can control instead, so do not calculate solely from the signature date.

Plan the notice window

The notice must state an effective date within the applicable five-year statutory window. It must be served no earlier than 25 years after the grant in the ordinary §203 calculation and no later than two years before the selected effective date. In practical terms, service is ordinarily required 2–10 years before effectiveness. Publication grants and other unusual instruments require the Copyright Office’s detailed tables rather than a one-line formula.

Check every grant covered

A termination notice should identify the work, the grant being terminated, the rights covered and the effective date with enough precision for the grantee and the public record to understand what ends. If a creator signed separate agreements for print, translation, adaptation, soundtrack, merchandising or game distribution, each may require separate analysis and possibly separate notices.

Older grants: §304(c) and §304(d)

§304(c)

Section 304(c) addresses certain pre-1978 grants involving copyrights secured before January 1, 1978. Its five-year termination period is tied to the older copyright’s renewal and extension history, not simply to the date a contract was signed. The renewal record, prior grants and the identity of statutory successors therefore matter.

§304(d)

Section 304(d) was a limited additional opportunity for a narrow group of older copyrights secured between January 1, 1923, and October 26, 1939, when the required conditions were met. That opportunity is now historical: the last date to serve a §304(d) notice was October 26, 2017, and the last date to record it was October 26, 2019. A new filing cannot revive those expired deadlines.

Work made for hire is the threshold issue

Section 203 excludes works made for hire. The Copyright Office also identifies work-made-for-hire status as important under §§304(c) and 304(d). If the hiring party is the statutory author, an individual creator generally cannot use termination to reclaim that copyright as an author.

Employee-created work

A work created by an employee within the scope of employment can be a work made for hire. Labels such as “developer,” “staff writer” or “independent contractor” do not decide the issue by themselves; the actual relationship and duties do.

Commissioned work

A commissioned work qualifies only when the parties have the required signed writing and the work falls within one of the statutory categories for commissioned works. A contract calling something “work for hire” cannot substitute for those statutory requirements.

Why the classification must come before date arithmetic

Calculating a 35-year date is pointless if the work is legally a work made for hire or if the person seeking termination never owned the relevant copyright interest. Preserve the contracts, employment records, invoices, delivery materials and authorship documents before relying on a termination theory.

Who can exercise termination rights?

A living author

For a qualifying author-executed post-1977 grant, the living author generally exercises the termination right for the grant the author made. A later owner of the copyright does not automatically acquire the author’s personal statutory power.

Joint authors

For a post-1977 grant covering a joint work, §203 generally requires a majority of the authors who executed the grant. The signature rule is not interchangeable with the rules for older grants, and a contract’s definition of “author” does not settle statutory authorship.

Deceased authors and successors

If an author has died, the author’s statutory termination interest is exercised by qualifying successors under the Act. The order of priority and required signatures can differ from the living-author rule and from pre-1978 procedures. Gather wills, probate records, assignments and family-interest documents before serving notice.

Notice, service and recordation: the procedure

Termination is not self-executing merely because the statutory period has arrived. Follow the applicable provision and the Copyright Office’s current filing requirements.

  1. Identify the grant and the work. Locate the signed instrument, amendments, schedules and later assignments. State which copyright rights and territories are included.
  2. Determine the statutory window. Confirm the grant execution date, copyright-securing date, publication facts, work-made-for-hire status and whether a successor must act.
  3. Choose an effective date. It must fall within the applicable five-year period and satisfy the minimum and maximum notice lead times.
  4. Prepare the notice. The notice must identify the work and grant, state the effective date and be signed by the persons authorized under the relevant section.
  5. Serve the grantee or successor. Service must be made on the current grantee or successor in interest as required by the statute. Keep proof of the date and method. If that information is not in the notice, provide it with the recordation submission.
  6. Record before the effective date. The Copyright Office requires a true, correct, complete and legible copy of the signed notice as served, together with the applicable fee and cover sheet. Recordation after the effective date does not satisfy a deadline that required earlier filing.
  7. Preserve the evidence. Retain the served copy, delivery proof, recordation confirmation, agreements and chain-of-title materials in a permanent file.

Because the Office updates forms, fees and procedural instructions, verify the current requirements before filing. A defective notice or a missed window can leave the original grant in place.

What termination changes—and what it does not

Rights return only within the terminated grant

Termination ends the specified transfer or license, not every copyright interest connected with a project. If a notice covers only publishing rights, it does not automatically terminate a separate film, merchandising or software grant. The effective scope follows the grant and the notice.

Existing derivative works can continue

A derivative work prepared under the grant before termination may continue to be used under that grant. The statutory privilege does not extend to making new derivative works after termination. This distinction is critical for sequels, expansions, ports, adaptations, translations and remasters.

Termination does not resolve unrelated disputes

It does not by itself decide authorship, ownership of ideas, trademark rights, patent rights, contract royalties, employment claims or foreign-law rights. Those questions require separate analysis.

Applying the rules to a video game

A game should be treated as a collection of contributions and rights rather than automatically as one indivisible copyright asset. The Copyright Office describes two major components: the audiovisual material displayed on screen and the computer program that runs the game. Different parties can own those components, and separate registrations may be required when ownership differs.

Audit question Why it matters
Who created the code, art, music, writing, voice recording and other material? Each contribution may have a different author, employer, contractor or successor.
Was the contribution employee work within the employment scope? It may be work made for hire and outside an individual author’s §203 termination route.
Was it commissioned under a signed work-made-for-hire agreement and a statutory category? A label alone is insufficient; the statutory test must be satisfied.
What assignment or license was signed, and when? The execution date, rights granted and territory determine the possible route and timing.
Who currently holds the grant? Notice must reach the grantee or successor in interest, not merely the original publisher’s old address.
Was a sequel, adaptation, port or other derivative prepared before termination? Existing derivative uses may continue, while new derivative works generally are not covered by the pre-termination privilege.

A practical developer audit

  1. Create a rights map for the game’s code, audiovisual assets, music, narrative, characters, recordings, middleware-created output and promotional material.
  2. Attach every contributor’s employment agreement, contractor agreement, assignment, license and amendment to the relevant asset or bundle.
  3. Mark the execution date, copyright registration or publication information, territory, media and successor chain for each grant.
  4. Flag any agreement that claims work-made-for-hire status and test it against the employee or commissioned-work requirements.
  5. List every pre-termination sequel, expansion, port, adaptation or other derivative and the grant under which it was prepared.
  6. Have counsel calculate the applicable window and determine whether one notice or several notices are required.

Registration is evidence in the public record, not a substitute for proving ownership or termination eligibility. If the same party owns both the audiovisual material and the computer program, one application may cover both when the registration conditions are met; separate owners generally require separate applications.

Comparing a creator’s possible routes

Question §203 post-1977 grant §304(c) older grant §304(d) historical route
Grant date On or after January 1, 1978 Before January 1, 1978 Older grant in the narrow statutory category
Copyright date Usually a post-1977 work; verify the actual record Copyright secured before January 1, 1978 Copyright secured January 1, 1923–October 26, 1939, with other conditions
Work made for hire Excluded Can affect eligibility Can affect eligibility
Notice status Generally 2–10 years before the effective date Separate five-year period tied to renewal and extension history Service deadline passed October 26, 2017
Recordation status Must occur before the effective date Follow the applicable older-grant procedure Final recordation deadline was October 26, 2019

When two routes seem possible, compare the execution date, copyright and publication dates, whether publication rights were conveyed, the number of grantors and successors, work-made-for-hire status, notice and recordation deadlines, the rights and territory covered, and derivative works prepared before termination.

Common failure points

  • Using “35 years” as a universal answer. Publication grants and older copyrights use different calculations.
  • Ignoring work-made-for-hire status. A signed contract’s label is not conclusive, but a valid work made for hire is a major statutory exclusion.
  • Serving the wrong entity. Trace mergers, acquisitions and assignments to identify the current grantee or successor.
  • Counting from the wrong date. Execution, publication and copyright-securing dates can produce different windows.
  • Assuming one game contract covers every asset. Code, audiovisual material, music and commissioned contributions may have separate owners and grants.
  • Waiting until the effective date to record. Recordation must occur before effectiveness, and the submission must match the signed notice as served.
  • Assuming termination cancels existing sequels or ports. A derivative prepared under the grant before termination may retain continued-use protection.

Illustrative timeline (not a legal calculation)

Suppose an author signed a non-work-made-for-hire grant in 1988. The ordinary §203 framework may place the earliest effective date around 2023, with notice served within the permitted lead-time window. That example does not account for publication rights, later amendments, successor interests or the exact statutory table; the signed grant and official calculation control.

By contrast, a 1960 grant for a copyright secured before 1978 points first to §304(c), where the renewal and extension history controls. A claim relying on §304(d) should be checked against the expired 2017 service and 2019 recordation deadlines before any filing is considered.

When professional advice is essential

Consult a U.S. copyright attorney when the grant combines publication and adaptation rights, multiple authors disagree, an author has died, a game has many contractors, work-made-for-hire status is uncertain, the grantee has changed through corporate transactions, or a termination date is close. Counsel can review the actual chain of title, calculate the statutory window, identify all required signers and prepare service and recordation evidence.

The Bottom Line

Copyright reversion in the United States is a carefully timed statutory termination process, not an automatic undo button. For creators and game developers, eligibility turns first on the work-made-for-hire question and the exact grant; then on the correct statutory route, successor authority, notice timing, service and recordation. Treat each game component and each grant separately, and verify the current Copyright Office procedure before acting.
