Case Background: A company obtained a court judgment for over KRW 213 million in unpaid charter fees. By the time the judgment was final, the debtor had already transferred its only assets — a vessel and two patents — to a third party. There was nothing left to enforce against. Was there any recourse?
A Winning Judgment — But Nothing Left to Collect
※ This case is based on a matter handled by Atlas Legal. Certain facts have been modified to protect client confidentiality.
After the creditor’s charter fee claim arose, the debtor entered into patent assignment agreements for two patents on December 29, 2011, completing the transfer registration in favor of a third party on January 12, 2012. When the creditor obtained a judgment on January 17, 2013, the debtor’s assets — both the vessel and the patents — had already been transferred. The court voided the patent assignments as fraudulent transfers and ordered cancellation of the transfer registrations. The key legal reasoning is set out below.
1. Are Patents Subject to Fraudulent Transfer Claims in South Korea?
Under Article 406(1) of the Korean Civil Act, a creditor may apply to court to revoke any act involving property rights that a debtor performed with the knowledge that it would prejudice creditors, and to claim restoration of the original state. Patents carry economic value and constitute property rights, making them fully subject to South Korean fraudulent transfer law.
The Protected Claim Requirement
The creditor’s claim must have arisen before the fraudulent act. In the case described here, the charter fee claim arose around November 30, 2011, while the patent assignment was executed on December 29, 2011 — satisfying the timing requirement.
Elements of a Fraudulent Transfer Claim in South Korea
| Element | Description | Finding in This Case |
|---|---|---|
| Protected Claim | Creditor’s claim arising before the impugned act | Satisfied (charter fee claim arose Nov. 2011; assignment Dec. 2011) |
| Fraudulent Act | Disposition of property rights reducing common security | Satisfied (only assets — vessel and patents — transferred together) |
| Debtor’s Fraudulent Intent | Debtor’s awareness that creditors would be prejudiced | Presumed (sole assets disposed of) |
| Transferee’s Bad Faith | Transferee’s knowledge of the fraudulent nature | Presumed (no rebuttal evidence) |
2. How Is Fraudulent Intent Established in South Korea?
Proving a debtor’s subjective intent directly is rarely feasible. South Korean courts apply a presumption rule that significantly eases the creditor’s evidentiary burden.
The Presumption of Fraudulent Intent
The Supreme Court of Korea has held that when a debtor converts their only significant asset into easily dissipated cash, this constitutes a fraudulent transfer absent special circumstances, and the debtor’s fraudulent intent is presumed. The burden of proving good faith shifts to the transferee (Supreme Court Decision 2000Da41875, April 24, 2001).
In the case at hand, the court found that both the debtor’s fraudulent intent and the transferee’s bad faith were presumed and that there was no evidence sufficient to rebut that presumption.
What Must the Transferee Show to Rebut the Presumption?
The transferee must produce concrete evidence that they were unaware the transfer would prejudice creditors. It is not enough to show that a fair price was paid or that the transaction appeared commercially normal. The transferee must demonstrate actual lack of knowledge of the debtor’s financial condition. In practice, this is rarely achieved successfully.
3. How Are Multiple Asset Disposals Assessed in South Korea?
When a debtor transfers several assets in quick succession, South Korean courts must decide whether to evaluate each transfer individually or treat them as a single composite act.
The General Rule: Each Transfer Assessed Separately
The Supreme Court of Korea has stated that where a debtor makes a series of asset disposals, the default approach is to assess each act individually by asking whether that particular act caused or deepened insolvency (Supreme Court Decision 2012Da34740, March 27, 2014).
The Exception: Treating Multiple Transfers as One Act
However, the same decision recognized that where there is a special circumstance justifying treating a series of acts as a single transaction, the court should assess their combined effect on solvency. The relevant factors are:
| Factor | Description |
|---|---|
| Same transferee | All disposals made to the same counterparty |
| Temporal proximity | Disposals made close together in time |
| Relationship between parties | Special relationship between debtor and transferee |
| Common motive or opportunity | Same underlying purpose driving all transfers |
In the case discussed here, the patent assignment (December 29, 2011) and the vessel sale (January 6, 2012) were both made to the same party in close succession, as part of unwinding a joint operating agreement and settling mutual claims — satisfying all four factors. The court assessed the two transfers together as a single composite act.
4. Can a Patent Transfer Made to Settle Debts Still Be Voided in South Korea?
Debtors frequently argue that a patent transfer was simply part of a legitimate commercial settlement and therefore cannot constitute a fraudulent transfer. South Korean courts have addressed this argument directly.
Settlement Purpose Does Not Override Creditor Protection
The court in this case acknowledged that the patent assignment arose from the unwinding of a joint operating agreement between the parties. Nevertheless, it held that viewing the patent assignment and vessel sale together, the transferee had effectively received all of the debtor’s only assets — and that this constituted a fraudulent transfer prejudicing general creditors, regardless of the settlement framing.
The Underlying Principle
Regardless of the label attached to a transaction — debt settlement, security enforcement, or joint venture wind-down — if the net effect is to remove assets from the debtor’s estate and leave general creditors without recourse, South Korean law treats the transaction as a fraudulent transfer. Where the transfer favors a specific creditor over others, separate rules on preferential transfers may also apply and should be analyzed independently.
5. How Are Patents Restored After a Fraudulent Transfer Is Voided in South Korea?
Revocation of the fraudulent act must be accompanied by restoration to the original state. For real property, this means cancellation of the ownership transfer registration. For patents, the equivalent remedy is cancellation of the patent transfer registration at the Korean Intellectual Property Office (KIPO).
The Court Order in This Case
The court ordered the transferee to complete the cancellation of the full transfer registration for both patents — referencing the specific KIPO filing number — thereby restoring ownership in the patents to the debtor.
Practical Considerations for Creditors in South Korea
- Statute of limitations: Under Article 406(2) of the Korean Civil Act, the claim must be filed within one year of learning the grounds for revocation, and within five years of the date of the fraudulent act.
- Identifying the correct defendant: The action must be brought against the transferee. If the patents have been further assigned to a third party, a separate claim against the subsequent transferee must be considered.
- Remedy if re-transfer has occurred: Where the patents have already been re-assigned, value-based compensation may substitute for in-kind restoration.
- Interim injunction: If there is a risk the transferee may re-assign the patents during litigation, a provisional injunction against disposition should be sought promptly.
6. FAQ
Fraudulent transfer claims involving patents and other intellectual property in South Korea require careful analysis of how the transfers were structured and timed. Our team’s review of this matter confirmed that where multiple assets are disposed of together, the key to establishing fraud lies in framing the transfers as a single composite act and demonstrating their combined impact on the debtor’s solvency.
