<![CDATA[The convergence between digital technology and the Intellectual Property (IP) ecosystem has raised serious challenges for the protection of personal data attached to IP holders, ranging from unauthorized data use to identity misuse and data leakage. This study examines privacy protection as a form of digital justice within Indonesia's IP ecosystem and compares it with the legal frameworks of Japan, the European Union, and the United States. Using a normative legal method with a qualitative and comparative approach, this research analyzes primary legal materials, including Indonesia's Personal Data Protection Law, Electronic Information and Transactions Law, and sectoral IP regulations, alongside Japan's APPI, the EU's GDPR, and the US's DMCA and CCPA. The findings show that Indonesia already possesses a normative basis for privacy protection within its IP framework, yet this basis remains fragmented across several laws and has not been fully harmonized in policy or technical implementation. The scope of privacy protection in this context extends across three stages: registration and administration, technology development, and commercialization and enforcement. Comparative analysis reveals that Japan relies on strong institutional oversight, the EU embeds data protection as a fundamental right through privacy by design, while the US applies a flexible, sector-based approach. These findings suggest that Indonesia needs stronger institutional capacity and regulatory harmonization to achieve digital justice in its IP ecosystem.]]>
