A New Era of Patent Enforcement in Republic of Korea: Stronger Protection and Heavier Penalties
Jongsun Kim - KLP IP FIRM (Republic of Korea)
The South Korean intellectual property landscape is undergoing a monumental shift. Recent legislative amendments have significantly raised the stakes for patent infringement, signaling the government’s firm commitment to transforming Korea into a “high-protection” IP jurisdiction. For multinational corporations, these changes mean both enhanced protection for their assets and increased legal risks in their Korean operations.
- Closing the Loophole: “Exporting” as an Act of Infringement
Previously, the Korean Patent Act did not explicitly list “exporting” as an act of practicing a patent. This led to a significant legal loophole where companies could manufacture infringing goods in Korea and export them entirely to overseas markets without being held liable for direct patent infringement under the Patent Act.
- The Former Limitation: Due to this gap, patent holders often had no choice but to seek remedies through the Korea Trade Commission (KTC), alleging “unfair international trade practices” rather than pursuing a straightforward patent infringement lawsuit in civil court. While the KTC provides effective relief, the lack of a direct cause of action in court for “exporting” remained a hurdle for rights holders.
- The Change: The amended Patent Act now explicitly includes “exporting” as a form of patent exploitation (Article 2).
- Implications: Rights holders can now seek direct injunctions and damages in court against entities that use Korea as a global production hub for infringing products, even if no domestic sales occur. This provides a much more robust and direct legal path for IP enforcement.
- Effective Date: This amendment was promulgated on January 21, 2025, and will take effect on July 22, 2025.
- Escalated Financial Risk: Quintuple (5x) Punitive Damages
Korea is introducing one of the most stringent punitive damage regimes in the world to deter willful technology theft and trade secret misappropriation.
- The Change: The cap for punitive damages for willful infringement of patents and trade secrets has been increased from the previous 3 times to up to 5 times (Quintuple Damages) the actual loss.
- The Impact: This shift moves Korea beyond the “treble damages” standard common in many jurisdictions (like the U.S.), making willful infringement a high-stakes financial risk that could threaten a company’s corporate existence.
- Effective Date: This provision for patents and trade secrets became effective on August 21, 2024. (Note: Similar 5x damages for Trademarks and Designs will follow on July 22, 2025)
Strategic Recommendations for Global Businesses
“Korea is no longer a ‘safe harbor’ for production-only models or minor infringements. The cost of legal oversight has increased fivefold.”
- Strict FTO (Freedom to Operate) Audits: With export activities now constituting direct infringement, companies must conduct thorough clearance searches not just for products sold in Korea, but also for those manufactured or transshipped through Korean ports.
- Evidence of Good Faith: Given the 5x penalty for “willful” acts, documenting a robust internal compliance process and seeking legal opinions early can be crucial in proving a lack of “willfulness” in potential disputes.
Proactive Enforcement: For foreign patent holders, these changes provide a powerful new toolkit. Korea’s specialized IP High Court and the increased damage awards make it an increasingly attractive venue for enforcing global IP portfolios.
