Supreme Court clarifies the exclusive jurisdiction of the IP High Court in hearing IP-related civil cases (Ruling 2024Da228906 | October 31, 2024)

Introduction Civil cases concerning IP rights including patent rights, utility model rights, design rights, trademark rights, and plant variety protection rights fall under exclusive jurisdiction of specific courts. The first trial is under the exclusive jurisdiction of the Seoul Central District Court, Suwon District Court, Daejeon District Court, Daegu District Court, Busan District Court, or Gwangju District Court, while the second trial falls under the exclusive jurisdiction of the IP High Court. In this regard, the question arises as to what cases are encompassed within “civil cases concerning IP rights”. Supreme Court ruling 2024Da228906 (October 31, 2024) According to the Supreme Court, the reason for stipulating a separate rule on jurisdiction for cases concerning IP rights is that, generally, the hearing and judgment of disputes concerning such rights require specialized knowledge and an understanding of relevant technology; concentrating these cases in specialized courts contributes to the appropriate protection of IP rights. Last year, in ruling 2023Da277260 (December 28, 2023) pertaining to a damages claim, the Supreme Court confirmed that, even when the first trial is judged by a single judge of a district court (including small claims cases), the appeal still falls under the exclusive jurisdiction of the IP High Court. This latest Supreme Court ruling we are discussing (2024Da228906 | October 31, 2024) pertains to a case on liquidated damages. Specifically, the plaintiff, Defendant 1, and Defendant 2 entered into a settlement agreement to resolve a patent-related dispute and concluded the dispute by withdrawing ongoing invalidation trials or lawsuits. Later, the plaintiff filed a main action seeking payment of liquidated damages, claiming the defendants breached the agreement, while Defendant 1 filed a counterclaim, asserting that the plaintiff breached the agreement and also sought payment of liquidated damages. The first trial decision was rendered by a single judge of the district court, and the second trial decision was rendered by the district court’s panel division. In this regard, the Supreme Court held that the main and counterclaims in this case involve issues requiring an understanding of specialized knowledge or technology related to IP rights. Therefore, these claims fall within the scope of IP cases, and the second trial falls under the exclusive jurisdiction of the IP High Court. Consequently, the Supreme Court overturned the appellate court decision and transferred the case to the IP High Court. The Supreme Court particularly ruled as follows on the issue of whether an understanding of specialized knowledge or technology related to IP rights is necessary: Regarding the main action, it is necessary to examine and judge whether specific acts of the defendants fall under prohibited acts specified in the settlement agreement. This requires a comprehensive review of the details and outcomes of the patent-related invalidation trial, trial decision cancellation lawsuit, and scope confirmation trial,     as well as the identity between the technology for which the plaintiff applied and the plaintiff’s patented invention technology. Regarding the counterclaim, it is necessary to examine and judge whether specific acts of the plaintiff fall under prohibited acts specified in the settlement agreement. This requires a comprehensive review of the details of the defendants’ patented invention technology and whether the plaintiff included false information regarding the defendants’ patented invention in an application for designation as a new construction technology.   Comment This Supreme Court ruling is significant in clarifying that if the substantive nature of a dispute requires an understanding of specialized knowledge or technology related to IP rights, such cases are regarded as “civil cases concerning IP rights” and thus fall under the exclusive jurisdiction of the IP High Court.

What Happens to Patent Licensing Agreements and Patent Non-Implementation Agreements When a Patent is Invalidated?

When a patent is invalidated after a Patent Non-Implementation Agreement is executed, what becomes of the legal relationship surrounding the agreement? Under the Korean Patent Act, if a patent is invalidated, it is considered to have never existed from the outset. Does this mean that if the other party used the patented invention, it is no longer considered a breach of contract? Additionally, if the other party proves that the invention they used falls under the category of free-to-use technology, would this eliminate their liability under the agreement? This article will first review relevant Supreme Court decisions regarding Patent Licensing Agreements and the invalidation of the related patent and then introduce the latest Supreme Court ruling delivered on November 20, 2024, which addresses these issues.    ______________________________________________________________________________________________________________________________________________________ Patent Licensing Agreements and the Invalidation of the Related Patent (Supreme Court Decision 2012Da42666, 42673 | November 13, 2014)    1.    Does a Patent Licensing Agreement Become Void If the Underlying Patent is Invalidated?    When a patent is invalidated after the execution of a licensing agreement, the patent is deemed to have never existed, except in specific circumstances. However, unless the patented invention that is the subject of the contract was impossible to implement, the Patent Licensing Agreement cannot be deemed to have been in a state of initial impossibility at the time of its execution. It is only upon the invalidation of the patent that the agreement is considered to enter a state of non-performance.    2.    Is the Patentee Obligated to Refund Royalties for the Period the Agreement Was Valid?    Even if the patent is invalidated, the patentee is not required to refund royalties received for the period when the licensing agreement was valid, unless the agreement was initially void or there were separate grounds for invalidity of the agreement.     A subsequent Supreme Court ruling (2018Da287362, April 25, 2019) reinforced this view, stating that patentees can claim royalties for the valid period of the agreement.    3.    Can a Licensing Agreement Be Voided Due to a Mistake About Patent Validity?    Given the inherent possibility of a patent being invalidated after registration, a licensing agreement cannot be voided for mistake unless the validity of the patent was explicitly agreed upon as a fundamental term of the contract. ______________________________________________________________________________________________________________________________________________________ Patent Non-Implementation Agreements and the Invalidation of the Related Patent (Supreme Court Decision 2024Da270105 | November 20, 2024)    1.    Does a Non-Implementation Agreement Lose Effect Upon Patent Invalidation?    Even if a patent is invalidated after the execution of a Non-Implementation Agreement, the agreement is not void from the outset. Instead, it becomes unenforceable only after the patent’s invalidation. Thus, unless there are separate grounds for invalidity of the agreement, the patentee can claim damages for breach of the agreement during the valid period    2.    Can the Defendant Argue Freedom-to-Use Technology as a Defense Against Breach    The fact that the defendant’s use of the invention constitutes freedom-to-use technology (i.e., technology that can be easily derived from public knowledge) does not exempt them from the obligations under the Non-Implementation Agreement, which remains binding as per the parties’ mutual understanding. ______________________________________________________________________________________________________________________________________________________ Conclusion The Supreme Court has clarified that neither licensing agreements nor non-implementation agreements are automatically void when the associated patent is invalidated. In licensing agreements, patentees can claim royalties for the period before invalidation, and refunds are not owed for royalties already received during that time. In non-implementation agreements, patentees can claim damages for breach of contract during the period before the patent’s invalidation, and defendants cannot evade liability by arguing freedom-to-use technology.

Korean IP High Court upholds “upcycling” trademark infringement decision

 ▒  ORIGINAL DECISION (Seoul Central District Court - Case 2022GaHab513476) One of the most interesting recent developments in Korea for brand owners was the 12 October 2023 decision by Seoul Central District Court dealing with the issue of whether “reforming” genuine goods into different goods constitutes an infringement of the brand owner’s trademark rights, and if the doctrine of exhaustion (AKA first sale doctrine) applies to such goods. We previously wrote an article on this topic (see here), but in summary: The dispute involved a defendant who provided a service of altering branded bags (including those offered by the plaintiff) by using fabric and materials displaying the brand’s registered trademarks. Customers would submit original/genuine branded items, which the defendant would deconstruct and reassemble into modified products. The reformed items bore the original brand’s logo and design elements. See image below, taken from the first instance decision, showing how bags were transformed into wallets, card cases, smaller bags etc.: The court addressed whether transforming genuine products into new forms, e.g., bags to wallets, infringes on trademark rights. While the first sale doctrine limits the original trademark owner's control post-sale, issues arise when altered products are resold. Plaintiff claimed the transformations constituted infringement of their trademark rights and harmed their brand’s distinctiveness. Defendant argued that the modifications were for the owner’s use only, not resale, and did not damage the identity of the original product, and that there would be no source confusion as products were only distributed to the customer who provided the original item. The court ruled the transformations went beyond the scope of simple processing/repair and constituted an act of production, damaging the original product’s identity, and also commented that while the recipient of the products would not be confused as to their source, general consumers could still be confused if the reformed products are viewed by or transferred to a third party. Ultimately, the court ruled that the brand owner’s trademark rights were not exhausted and awarded damages in favor of the plaintiff.    ▒  APPEAL DECISION (IP High Court - Case 2023Na11283) The original decision was appealed to the IP High Court, which handed down a ruling on 28 October 2024 upholding the decision of the first instance court. Damages of 15 million KRW (approx. $10,750 USD) were awarded, together with an injunction barring the appellant from using materials bearing Louis Vuitton’s trademarks in the production of bags and wallets. While largely affirming the lower court’s stance, the IP High Court offered clarifications on several points: Commercial Value of Reformed Products: In terms of trademark usage, a “product” refers to an item that, in itself, has exchange value and is capable of being an independent object of commercial transaction. Reformed products such as wallets and bags hold exchange value in themselves. Furthermore, given that the Louis Vuitton trademark is widely known as indicating the origin of the plaintiff’s bags or wallets, the reformed products carry considerable exchange value. Additionally, considering the active resale market for luxury products, reformed products are also likely to be circulated in the second-hand market. Repair vs Reform:  The owner of an item, when it becomes worn or damaged, may utilize a repair service to restore the item to its original appearance or function. For items that have undergone simple repairs, the trademark on the repaired item is not generally perceived as identifying the repair service provider, except in special cases. However, if an old or damaged item is used as a raw material to produce a new item different from the original, the trademark on the new item could be perceived as representing the manufacturer of the new product, rather than the original manufacturer. Considering the products in question, it is reasonable to deduce that the defendant completely dismantled the original product, cut its parts, and recycled the parts as raw materials through processes involving physical/chemical treatment, stitching, attachment of components, and application of trademarks. In comparison to the original item, the reformed product differs significantly in terms of quantity (e.g., two or more new items manufactured from one original item), size, volume, shape, appearance, and function. Therefore, the reformed product is considered a new product, and can be distinguished from a repaired/decorated product where restoring to its former state is feasible. Consumer Confusion & Brand Dilution:  The court emphasized that even in cases where the reformed products are returned to the original owners rather than sold to third parties, the presence of the brand’s trademark on significantly altered items can still lead to consumer confusion. The court highlighted that even if the modifications are requested by the owners, reformed goods bearing the original trademark risk damaging the brand’s reputation by diluting its association with quality and consistency. This underscores that consumer perception remains a critical factor in determining infringement, focusing on the “general consumer” who may encounter the modified goods in secondary or social contexts, potentially mistaking them as authentic brand products. Exhaustion Doctrine:  The court also reiterated and clarified the limitations of the exhaustion doctrine. While brand owners cannot restrict the resale of their products post-purchase, the exhaustion doctrine does not apply when the modifications transform the product’s core characteristics. Given that the defendant’s alterations affected the products' structure and presentation — resulting in entirely new forms like wallets from handbags — the court found these alterations to exceed permissible "repair" and to encroach upon the brand owner’s rights. The appellant criticized the ruling, stating that the legal judgement lacked common sense (Source: News1), and has further appealed the matter to the Supreme Court.   ▒  COMMENTS We will keep a close eye on this issue and report any further updates if and when the case is heard by the Supreme Court. In the meantime, the IP High Court’s decision signals a strong stance against unauthorized brand modification, especially in cases where significant alterations may harm brand integrity or confuse consumers.  Brand owners may find this ruling advantageous for enforcing their rights over products in secondary markets. The decision also serves as a warning to businesses engaged in reformation/upcycling services, indicating that they must consider the degree of alteration and the potential for consumer confusion when handling branded items.   Written by Jonathan MASTERS and Sang-eun SHIN
