Patent valuation plays a critical role in the creative economy; particularly as intellectual property assets are increasingly utilized as collateral in financial transactions. However, significant challenges remain in the valuation process, particularly for patents, which are intangible assets with high economic potential but complex valuation methods. This study aims to address the legal and valuation challenges surrounding patents in IP-based financing and provide recommendations to enhance legal certainty. The research adopts a normative juridical approach, analyzing relevant regulations and cases. The results highlight the need for a comprehensive legal framework in Indonesia to mitigate uncertainties in patent valuation. Addressing the uncertainty in patent valuation requires a proactive legal framework that ensures predictability, transparency, and consistency. By strengthening regulations and learning from international best practices, Indonesia can unlock the potential of its creative economy and position itself as a competitive player in the global IP market. By addressing these challenges, Indonesia can enhance the credibility and effectiveness of IP-based financing, fostering innovation and economic growth in the creative economy sector.
