Design Right Invalidation & Platform Takedown Damages South Korea

1. What standard do South Korean courts apply when judging the right holder’s negligence?

South Korean courts assess the right holder’s fault as of the time of enforcement, examining whether the right holder knew the grounds for invalidity or could have easily discovered them through ordinary investigation and legal review. Mere retroactive invalidation does not establish negligence.

The Seoul High Court’s Framework

The Seoul High Court articulated the standard for liability arising from design right enforcement warnings as follows:

“A warning given by a design right holder to a competitor’s business partner, as a precursor to litigation, is an act that may harm the competitor’s business goodwill. Therefore, like filing a lawsuit, it becomes unlawful only when the right holder, knowing there is no factual or legal basis, or when such absence of basis could have been easily discovered through the factual investigation and legal review ordinarily required for filing a design right infringement action, nonetheless proceeds with the warning.” (Seoul High Court, Decision 2013Na64023, July 16, 2015)

Factors That Negate Negligence in South Korea

Courts in South Korea have cited the following circumstances as negating the right holder’s fault:

• The design registration was valid and subsisting at the time of enforcement
• Invalidation proceedings and final invalidity decisions all occurred after the enforcement action
• There was no evidence the right holder specifically knew of invalidity grounds at the time
• The right holder had no prior knowledge of the specific prior designs later cited in the invalidity decision
• There were sufficient objective grounds to conclude the allegedly infringing product fell within the right’s scope

The Patent Court’s Approach

The Patent Court has held that even where the right holder filed a utility model application for a similar design or sold similar products before filing the design application, such facts alone do not support an inference that the right holder knew or could have known about invalidity at the time of filing. Design similarity assessment is technical and specialized, and the plaintiff bears the burden of proving specific awareness of invalidity grounds. (Patent Court, Decision 2017Na2240, April 13, 2018)

2. Does platform takedown automatically establish causation in South Korea?

In South Korea, takedowns or content suspensions by e-commerce platforms and portals are decisions made independently by the platforms based on their own internal review criteria. The right holder’s complaint alone does not automatically result in a takedown, so proximate causation between the complaint and the takedown must be separately established.

The Seoul Central District Court’s Ruling

The Seoul Central District Court addressed causation in the context of online platform complaints as follows:

“The mere fact that the plaintiff filed a design right infringement report with an online shopping mall does not automatically result in a sales-ban action against the defendant’s product. Rather, the online shopping mall makes the decision whether to impose a sales ban based on its own strict internal review criteria. No circumstances were found to establish that the sales ban against the defendant’s product resulted from the plaintiff’s report.” (Seoul Central District Court, Decision 2016Gahap570416, February 15, 2017)

In the same decision, the court applied the same reasoning to portal content suspensions, holding that such actions reflect the portal’s own strict internal review criteria and self-determined judgment. Platform actions therefore cannot be automatically attributed to the complainant.

Causation With Respect to Business Partners in South Korea

Similarly, the Seoul Eastern District Court held in a case involving a warning letter to a major Korean retailer that insufficient evidence existed to find the retailer demanded product replacement because of the warning letter. The court therefore rejected causation. (Seoul Eastern District Court, Decision 2011Gahap16989, August 22, 2013; affirmed by Seoul High Court, Decision 2013Na64023, July 16, 2015)

Practical Implications

A plaintiff in South Korea seeking damages must specifically prove what basis and procedure the platform used to decide on the takedown, and whether the right holder’s complaint was the decisive factor. Mere temporal sequence—”sales stopped after the complaint”—does not establish proximate causation.

3. Does retroactive invalidation render every prior enforcement action unlawful in South Korea?

No. South Korean courts have consistently held that the finalization of an invalidation decision alone does not render prior enforcement actions unlawful. A separate inquiry into the right holder’s fault at the time of enforcement is always required.

Explicit Holding of the Patent Court

The Patent Court in South Korea addressed this issue as follows:

“Although the design right is deemed to have never existed once the invalidation decision becomes final, this circumstance alone does not render unlawful the plaintiff’s act of asserting infringement before the invalidation decision. The preliminary issue is whether the plaintiff knew or could have known, before the invalidation decision, that the design registration was invalid.” (Patent Court, Decision 2017Na2240, April 13, 2018)

The Seoul Eastern District Court’s Analysis

The Seoul Eastern District Court reached the same conclusion in a similar case, holding that even where a design right is retroactively invalidated, the right holder may, before such invalidation, demand cessation of infringement in a socially reasonable manner based on the design right. Retroactive invalidation cannot convert prior lawful enforcement into unlawful conduct. (Seoul Eastern District Court, Decision 2011Gahap16989, August 22, 2013)

Analytical Structure

4. Can the corporate CEO be held personally liable in South Korea?

Generally no. Under South Korean corporate law, when a representative director acts within their authority on corporate business, they are not presumed to bear personal liability separate from the company. Personal liability requires independent tortious conduct involving the director’s own intent or gross negligence.

Liability Structure Under the Korean Commercial Act

When a Korean representative director causes harm to a third party in the course of executing business duties, the company bears liability under Article 35 of the Korean Civil Act or Articles 389(3) and 210 of the Korean Commercial Act. Personal liability to third parties under Article 401 of the Korean Commercial Act is limited to cases of “bad faith or gross negligence in the performance of duties.”

Application in Practice

Design right enforcement, such as a platform takedown request, is typically part of corporate intellectual property management. Where the right holder is a Korean corporation and enforcement is conducted in the corporation’s name, no basis exists in principle to attribute separate tort liability to the representative director personally, as long as proper procedures were followed.

A plaintiff naming the CEO individually as a defendant must specifically plead and prove independent tortious conduct by the director, involving either bad faith or gross negligence distinct from the corporate action.

Why This Matters for Foreign Businesses in South Korea

Foreign businesses holding or acquiring design rights in South Korea face distinctive exposure in this area. Designs licensed or assigned from foreign creators carry particular risk because novelty under the Korean Design Protection Act is assessed against both domestic and overseas prior disclosure. A design that was sold or publicly shown abroad before the Korean filing date may be invalidated on novelty grounds — creating downstream liability risk if enforcement was already underway.

Conversely, foreign sellers on Korean e-commerce platforms who receive takedown notices should not assume that platform removal equals legal liability. As shown above, Korean courts distinguish sharply between the platform’s independent decision and the complainant’s action. The right forum, evidence, and response strategy depend on whether the foreign party is the right holder or the target of enforcement.
