[1st MIKOTAMA Case Law Study Session]
We will be holding an event titled "Exploring the Specific Criteria for 'Substantial Identicality' under Article 2, Paragraph 1, Item 3 of the Unfair Competition Prevention Act - Based on the Latest Fashion Product Examples."
[November 20, 2026 (Thursday) 15:00~]

Article 2, Paragraph 1, Item 3 of the Unfair Competition Prevention Act, which frequently appears in cases of counterfeit fashion products, regulates acts that rely on the form of another person's product and create a form that is substantially identical to it (Article 2, Paragraph 5). Of these, there has been much debate about what criteria should be used to determine "substantial identity" and what factors should be emphasized.
In this study session, lawyer Tahara, a former judge who has handled numerous fashion-related cases, and lawyer Ebisawa, who focuses on fashion law, will delve into the specific criteria for "substantial identity" through the latest cases and court precedents.
Furthermore, a social gathering is planned after the study session, where attendees can network with each other.
Legal professionals, lawyers, legal trainees, and bar exam candidates interested in fashion law, fashion-related cases, or Article 2, Paragraph 1, Item 3 of the Unfair Competition Prevention Act are encouraged to participate.

What is the MIKOTAMA Case Law Study Group?
This study group will focus on important recent court precedents, with a lawyer who is a former judge providing clear explanations based on the court's decision-making process and the judge's perspective. The aim is to deepen understanding of the scope of the precedents, their impact on practice, and future issues, while also sharing diverse viewpoints and practical challenges through discussions with participating lawyers and corporate legal professionals.
This is a practical study group that goes beyond simply explaining case law, aiming to gain new insights and perspectives through interactive discussions.
