This research aims to analyze the characteristics, legal protection, application of principles between copyright and trademarks, and the potential disputes that arise. The urgency of this research lies in the need for harmonization between the declarative principle in copyright and the first-to-file principle in trademarks to address the potential legal conflicts that often arise due to the overlapping protection of these two intellectual property rights. This research method uses a normative juridical type of research with secondary data as the main data. The research results indicate that differences in protection principles can trigger legal disputes, especially when elements of copyrighted works are used as trademarks without permission. The novelty of this research is the recommendation for the implementation of cross-database mechanisms and policies for the cancellation of trademark registrations that violate copyright to prevent conflicts. The novelty of this research is to examine the legal relationship between copyright and trademark more holistically, providing an approach based on the Economic Analysis of Law (EAL) to assess the effectiveness of legal protection.

In conclusion, the harmonization of the declarative principle and the first-to-file principle can be achieved through enhanced synergy among relevant institutions, education for creators and entrepreneurs, and strengthened regulations to ensure fairness, legal certainty, and balanced protection of economic rights.
