Fair Use: What Is It? American Artists File Class Action Lawsuit Against AI Company for Copyright Infringement
The recent advancements in generative AI technology have been remarkable. However, as AI development progresses, the potential for lawsuits concerning copyright infringement by AI is likely to increase. In the United States, there has been a lawsuit filed by an artist alleging copyright infringement of images generated by AI, which could become an important precedent for AI copyright infringement cases.
Could similar lawsuits occur in Japan?
Here, we will introduce a recent U.S. lawsuit involving AI copyright infringement and explain the differences between Japanese and American copyright laws.
Copyright Infringement Lawsuits Involving AI in the United States
In January 2023, three companies—Stability AI, Midjourney, and DeviantArt—were sued by artists who claimed that their works were copied without permission through web scraping and used for machine learning, thereby infringing on their copyrights.
In April of the same year, these companies requested a federal court in San Francisco to dismiss the lawsuit brought by the artists. They argued that the use of copyrighted works for machine learning falls under the principle of fair use. The court will now consider both parties’ arguments before deciding whether to dismiss the copyright infringement lawsuit concerning images generated by AI.

What is Fair Use?
Fair Use is a legal defense against claims of copyright infringement under United States copyright law. According to Section 107 of the U.S. Copyright Act, the unauthorized use of a copyrighted work is not considered an infringement if it is deemed to be fair use, based on four factors of assessment.
Whether the use qualifies as fair use is determined based on the following four factors:
- The purpose and personality of the use
- The nature of the copyrighted work
- The amount and substantiality of the portion used in relation to the copyrighted work as a whole
- The effect of the use on the potential market for or value of the copyrighted work
Fair use is evaluated on a case-by-case basis.
The Relationship Between AI and Copyright in Japan
Regarding the concept of AI and copyright, the Agency for Cultural Affairs, at the Copyright Seminar for the fiscal year Reiwa 5 (2023), presented the view that one should consider separately the “AI development and learning phase” and the “generation and utilization phase,” as different articles of the Japanese Copyright Law apply to each stage.

In the aforementioned U.S. litigation, the issue pertains to the “AI development and learning phase.” Under Japanese Copyright Law, Article 30-4 explicitly permits the use of copyrighted works for machine learning.
Permissible Uses Under Article 30-4 of the Japanese Copyright Law
In Japan, the use of copyrighted works for machine learning is explicitly permitted under the law. This is stipulated in Article 30-4 of the Japanese Copyright Law, which allows users to utilize copyrighted works for machine learning without obtaining permission from the copyright holder.
This provision was established to promote the development of AI. Developing AI requires a vast amount of data, and obtaining permission from copyright holders for all data can be challenging. Thanks to this provision, AI developers can use copyrighted works for machine learning without the need for permission, thus facilitating easier AI development.
