Major Trademark Law Changes in South Korea Effective July 2025

Introduction and Overview of Amendments 

The National Assembly of the Republic of Korea enacted substantial amendments to the Trademark Act, which are set to come into effect on 22 July 2025. These legislative revisions are aimed at improving procedural efficiency within the trademark registration framework and enhancing enforcement mechanisms available to rights holders. The key amendments comprise a reduction in the statutory opposition period from 60 days to 30 days, and an increase in the upper limit of punitive damages awarded in cases involving willful infringement, raising the cap from three times to five times the actual damages suffered. These reforms are indicative of South Korea’s broader effort to align its intellectual property regime with the evolving needs of the global commercial landscape.

Key Amendments: Opposition Period and Strengthened Enforcement

One of the principal amendments concerns the trademark opposition procedure. Under the revised provision, the opposition period has been curtailed from 60 days to 30 days following the publication of the application. This measure is intended to expedite the examination and registration process, thereby reducing unnecessary delays for applicants. However, it simultaneously imposes a more stringent deadline on third parties seeking to challenge applications on relative or absolute grounds. To accommodate legitimate concerns, the dual-stage opposition process has been retained. A preliminary notice of opposition may be filed within the 30-day period, followed by a supplementary statement of grounds. Foreign entities may be granted an extended timeline of up to 60 additional days to complete their submissions. The Act also preserves the mechanism for submitting pre-publication informational briefs, allowing interested parties to draw the attention of examiners to prior rights or relevant legal issues prior to publication.

The second key revision pertains to remedies for trademark infringement. The amendment raises the statutory ceiling for punitive damages in instances of intentional infringement, increasing the multiplier from three times to five times the quantum of actual harm proven. This enhancement is designed to deter infringers engaging in deliberate acts of trademark misappropriation, such as counterfeiting or unauthorized commercial exploitation, and to provide stronger legal recourse for aggrieved proprietors. The increased liability reflects a legislative intent to impose proportionate and dissuasive sanctions on bad-faith actors.

Implications and Conclusion

These amendments reflect the Republic of Korea’s continued commitment to strengthening its intellectual property infrastructure in line with global best practices. While the shortened opposition window will accelerate registration timelines, it also necessitates heightened vigilance among trademark owners, legal counsel, and businesses to ensure timely monitoring and enforcement of their rights. The revised enforcement regime, featuring more substantial punitive damages, is expected to act as a credible deterrent to willful infringement and bolster the overall efficacy of trademark protection.

Businesses operating in or planning to enter the Korean market are advised to reassess their trademark portfolios, implement proactive monitoring systems, and ensure readiness to respond within the newly prescribed time limits. The amendments represent a significant evolution in South Korea’s trademark law, striking a balance between procedural efficiency and enhanced substantive protection for rights holders in a dynamic commercial environment.
