Thumbnail Image

The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

A 27-year-old man from Kanagawa was referred to prosecutors by Chiba police for allegedly copying and using AI-generated images without permission as book covers, violating copyright law. Authorities determined the AI-generated images were protected works, marking Japan's first such legal action involving generative AI content.[AI generated]

Why's our monitor labelling this an incident or hazard?

The event explicitly involves a generative AI system used to create images. The unauthorized copying and commercial use of these AI-generated images constitute a violation of copyright law, which is a breach of intellectual property rights. This harm has materialized, as evidenced by the police investigation and legal proceedings. Therefore, this qualifies as an AI Incident because the AI system's use directly led to a legal violation and associated harm.[AI generated]

IGN
Why's our monitor labelling this an incident or hazard?
The event explicitly involves an AI system (Stable Diffusion) used to generate an image. The unauthorized reuse of this AI-generated image for commercial purposes without permission constitutes a violation of intellectual property rights, which is one of the harms defined under AI Incidents. The legal case and police accusation indicate that harm has occurred (copyright infringement). Therefore, this qualifies as an AI Incident rather than a hazard or complementary information. The event is not merely about AI development or potential harm but about an actual legal case involving harm caused by AI-generated content misuse.

Man who used generative AI to create image accused of copyright infringement, in potential landmark case

2025-11-21
Notebookcheck
Why's our monitor labelling this an incident or hazard?
The article focuses on a potential legal case regarding copyright infringement involving AI-generated images, which could set a precedent if it proceeds. The AI system (Stable Diffusion) is explicitly involved in generating the images. However, the harm (copyright infringement) is not confirmed or realized yet; it is a potential legal issue pending trial. Therefore, this event represents a plausible future harm scenario related to AI use, fitting the definition of an AI Hazard rather than an Incident or Complementary Information.

Japanese Legal Experts Say AI-Generated Images Could Qualify as Copyrighted Works

2025-11-22
Sankaku Complex
Why's our monitor labelling this an incident or hazard?
The article centers on legal experts and authorities evaluating the copyright status of AI-generated images, highlighting a case referred to prosecutors for alleged copyright infringement. While it involves AI systems and their outputs, the main focus is on legal interpretation and potential changes in intellectual property law rather than an actual harm or incident caused by AI. There is no direct or indirect harm described, nor a plausible future harm event. Therefore, this is best classified as Complementary Information, as it provides important context and updates on governance and legal responses related to AI-generated content.
