SummaryIn March 2023, the US Copyright Office published a Statement of Policy setting out its approach to registration of works containing material generated by AI.
The guidance states that only the human created parts of a generative AI work are protected by copyright. Accordingly, only where a human author arranges AI-generated material in a sufficiently creative way that ‘the resulting work as a whole constitutes an original work of authorship’ or modifies AI-generated content ‘to such a degree that the modifications meet the standard for copyright protection,’ will the human-authored aspects of such works be potentially protected by copyright.
This statement follows a decision by the USCO on copyright registration for Zarya of the Dawn ('the Work'), an 18-page graphic novel featuring text alongside images created using the AI platform Midjourney. Originally, the USCO issued a copyright registration for the graphic novel before undertaking investigations which showed that the artist had used Midjourney to create the images. Following this investigation (which included viewing the artist’s social media), the USCO cancelled the original certificate and issued a new one covering only the text as well as the selection, coordination, and arrangement of the Work’s written and visual elements. In reaching this conclusion, the USCO deemed that the artist’s editing of some of the images was not sufficiently creative to be entitled to copyright as a derivative work.
As part of its study of the copyright law and policy issues raised by AI systems, in August 2023, the USCO sought written comments from stakeholders on a number of questions. It had received over 10,000 comments by December 2023. The questions cover the following areas:
- The use of copyrighted works to train AI models – the USCO notes that there is disagreement about whether or when the use of copyrighted works to develop datasets is infringing. It therefore seeks information about the collection and curation of AI datasets, how they are used to train AI models, the sources of materials and whether permission by / compensation for copyright owners should be required.
- The copyrightability of material generated using AI systems – the USCO seeks comment on the proper scope of copyright protection for material created using generative AI. It believes that the law in the US is clear that protection is limited to works of human authorship but notes that there are questions over where and how to draw the line between human creation and AI-generated content. For example, a human's use of a generative AI tool could include sufficient control over the technology – e.g., through selection of training materials, and multiple iterations of prompts – to potentially result in output that is human-authored. The USCO notes that it is working separately to update its registration guidance on works that include AI-generated materials.
- Potential liability for infringing works generated using AI systems – the USCO is interested to hear how copyright liability principles could apply to material created by generative AI systems. For example, if an output is found to be substantially similar to a copyrighted work that was part of the training dataset, and the use does not qualify as fair use, how should liability be apportioned between the user and the developer?
- Issues related to copyright – lastly, as a related issue, the USCO is also interested to hear about issues relating to AI-generated materials that feature the names of likeness, including vocal likeness, of a particular person; and also in relation to AI systems that produce visual works 'in the style' of a specific artist.
In July 2024, the USCO published Part 1 of its Report on Copyright and Artificial Intelligence, focusing on Digital Replicas (also called 'deepfakes'). Based on the input received, the USCO has concluded that a new federal law is needed to deal with unauthorised digital replicas, as existing laws do not provide sufficient legal redress. This would cover all individuals, not just celebrities. However, whilst the paper also notes that creators have concerns over AI outputs that deliberately imitate an artist's style, it does not recommend including style in the coverage of the new legislation at this time.
Separately, a No Fakes Bill (Nurture Originals, Foster Art and Keep Entertainment Safe Bill) has also been proposed in the US Senate. The No Fakes Bill also proposes to enact federal protection for the voice and visual likeness of individuals. The Bill is endorsed by a number of associations representing performers and rights holders, and from within the creative community.
In January 2025, the USCO published Part 2 of its report, focused on copyrightability of outputs from using generative AI. The report concludes that outputs can only be protected by copyright where a human author has determined sufficient expressive elements. This can include situations where a human-authored work is perceptible in an output, or a human makes creative arrangements or modifications of the output. However, it will not apply in the case of mere provision of prompts. The report also confirms that the use of AI to assist in the process of creating/including AI-generated material in a larger human-generated work may be protected by copyright.
In May 2025, the USCO published a 'pre-publication' version of Part 3 of its Report, focusing on generative AI training. The report considers the steps involved in creating and deploying a generative AI system which involve using copyrighted works in ways that implicate the right of reproduction including: data collection and creation; training; RAG; and production of outputs. In relation to fair use, the Office notes that the responses it had received to its Notice of Inquiry were 'sharply divided'. Given that generative AI involves a spectrum of uses and impacts, the Office notes that it is not possible to prejudge litigation outcomes but does offer the following analysis:
- On the first factor, the Office expresses the view that training a generative AI foundation model on a large and diverse dataset will often be transformative but this will depend on the functionality of the model and how it is deployed. Meanwhile, the use of RAG is less likely to be transformative where the purpose is to generate outputs that summarise/provide abridged versions of copyrighted works, as opposed to hyperlinks. The USCO forms the view that the knowing use of a dataset consisting of pirated or illegally accessed works should weigh against fair use without being determinative.
- On the fourth factor, the effect of the use upon the potential market for or value of the copyrighted work (the most important factor), the Office identifies that where a model can produce substantially similar outputs that directly substitute for works in the training data, it can lead to lost sales. Even where outputs are not substantially similar, they can dilute the market for similar works in the training data, including by generating material stylistically similar to those works. The assessment of market harm will also depend on the extent to which copyright works can be licensed for AI training.
