When AI Copies Your Style: IP in the AI Era

An artist may object to a copied image, a misleading use of their name, an imitation of their style or an unwanted training use. These concerns can overlap, but they do not have the same legal test. Preserve the actual material and identify what happened before choosing a remedy.

What technical imitation research shows

Casper and colleagues’ 2023 study tested whether classifiers could associate generated imitations with particular artists. The results concern a specified model and evaluation method. They do not establish that viewers cannot distinguish originals, quantify lost commissions or decide whether a protected work was infringed.

Isohanni and Hietanen-Kunwald’s 2025 chapter on style and intellectual property, in Generative AI, Contracts, Law and Design (Springer), discusses moral rights, reputation and possible remuneration for name-based imitation. Those proposals are scholarly arguments, not an existing general right to compensation whenever an artist’s name appears in a prompt.

Identify protected expression in the actual work

Under the Swiss Copyright Act, the starting point is the work and the applicable protection conditions. A palette, technique or broad stylistic description is not by itself evidence of infringement. Equally, describing an output as “only in the style of” does not settle whether it reproduces protected expression from a particular work.

This diagram is a conceptual aid, not a legal test. Inspect composition and other claimed elements in their context. Distinguish an aesthetic resemblance, copying, an attribution statement and the evidence connecting an output to a source.

Moral rights are not a universal style monopoly

Berne Convention Article 6bis concerns claiming authorship and objecting to specified treatment of a work prejudicial to honour or reputation. It does not expressly create a general right against every false attribution or imitation of style. Domestic law determines available remedies.

In Switzerland, Copyright Act Articles 9 and 11 concern authorship recognition and integrity of the work. Their application requires attention to the work and conduct concerned. Misuse of a name may call for separate examination of personality, trademark or unfair-competition law; those routes have their own conditions and should not be presented as automatic recovery for stylistic similarity.

Training rights remain a separate question

Directive (EU) 2019/790, Articles 3 and 4, distinguishes text and data mining for scientific research by research organisations and cultural heritage institutions from the broader exception subject to rights reservation. Identify lawful access, purpose and the relevant reservation mechanism. An output-imitation test does not establish which training acts occurred or whether an exception applies.

Swiss copyright law has no equivalent of that rights-reservation mechanism. Copyright Act Article 24d permits reproduction for the purposes of scientific research where the copying is due to the use of a technical process and the works can be lawfully accessed; it does not apply to computer programs. The Federal Office of Justice’s 2024 legal analysis (in German) noted that, as far as it could see, Swiss courts had not yet decided whether compiling training datasets, or training itself, is a relevant reproduction. It names three existing exceptions that might apply depending on the case: internal use (Article 19(1)(c)), temporary copies (Article 24a) and scientific research (Article 24d), where research must be the main purpose. For works of fine art, such as paintings and graphic works, Article 19(3)(b) further restricts copying outside the private sphere, which narrows the internal-use exception. Examine each exception against the actual training activity; none is a general permission to train. Parliament has since instructed the Federal Council to improve the protection of intellectual property against misuse by AI (Motion 24.4596, transmitted in December 2025); no resulting amendment to the Copyright Act is in force yet.

Similarly, uploading a reference image introduces questions about that input and its permitted use. It does not make copyright irrelevant merely because a system can work with few examples. The Swiss Federal Institute of Intellectual Property treats training, use and output rights as distinct issues.

Build a record before making claims

Ada Studio proposes a practical evidence file and contract review, adapted to the jurisdiction and the client’s objective.

For new commissions, agree permitted tools and inputs, use of names and likenesses, disclosure, approvals and downstream reuse. Do not promise that a contract binds strangers or protects an entire style. A narrowly defined, documented permission can be more useful than an undefined claim to everything aesthetically similar.
