Borderless Principle of Territoriality – Patent Law

Introduction   Patent law has long developed around the principle of territoriality. That is, a patent granted in one country has effect only within the borders of that country and cannot be enforced against acts occurring in another jurisdiction. Patent registration and enforcement are independently handled under each national legal system.   However, with the rise of the global digital economy and the proliferation of online platforms, it has become increasingly common for acts occurring in one country to directly target markets in another. In such cases, the limitations of traditional territoriality become apparent, and there is a growing need to reinterpret its boundaries. The principle of territoriality becomes blurred. A noteworthy case that reflects this issue is the decision rendered by the Korean IP High Court in Case No. 2023Na10693 (May 22, 2025). Case Overview   This case involves an Italian company (“A”) holding a patent for sock knitting machines, which filed a lawsuit against a Chinese company (“B”), claiming that B’s actions in China infringed its Korean patent rights. Plaintiff A alleged that Defendant B manufactured infringing products in China and either sold or advertised them for sale in Korea.   The court acknowledged that B did manufacture the products in China but found the evidence insufficient to prove actual sales in Korea. However, it was confirmed that B had advertised the products in Korean on Chinese e-commerce platforms and its own website (hosted on servers located in China), and had established a system enabling Korean consumers to make purchases. The decision focused on two key issues:   Issue 1: Jurisdiction of Korean Courts in International Cases   As this case involved a foreign plaintiff (Italian) suing another foreign defendant (Chinese) for alleged infringement of a Korean patent, a key issue was whether the Korean court had international jurisdiction.   The court relied on Article 2(1) of the Act on Private International Law which allows Korean courts to have international jurisdiction if the parties or the subject matter of the dispute has a substantial relationship with Korea.   The court evaluated the substantial relationship by focusing on (a) whether the result of the infringement occurred in Korea; and (b) whether the defendant’s advertising activities targeted Korean consumers.   It concluded that since the advertisement was clearly aimed at Korean consumers and the infringement effect took place within Korea, Korean courts had proper jurisdiction.   Furthermore, Article 39(1) of the same Act specifically provides that in IP infringement cases, a lawsuit may be brought in Korea if the result of the infringement occurred in Korea or the infringing act was directed toward Korea.   Issue 2: Whether Overseas Advertising Constitutes Patent Infringement in Korea   Under Korean patent law, an “offer for sale” is a form of patent infringement. The main question here was whether B’s advertising activities—carried out on Chinese platforms and websites—could be deemed an “offer for sale” in Korea.   The defendant had provided product information in Korean, allowed payment in Korean Won, enabled ordering and delivery within Korea, and provided customer support for Korean consumers. Accordingly, the court determined that these actions constituted a practical attempt to induce sales to Korean consumers and thus qualified as an “offer for sale” in Korea. Conclusion   The court ultimately recognized the jurisdiction of Korean courts and ruled that the defendant’s advertising activities constituted an infringement of Korean patent rights. A permanent injunction was issued.   This case demonstrates how the principle of territoriality is being expanded and reinterpreted in the digital age. The traditional border-based limitations of patent rights are increasingly being neutralized in the online environment, and courts in various jurisdictions are now focusing more on actual impact and targeted markets rather than formal geographical boundaries.   Japan’s Intellectual Property High Court has taken a similar approach. For example: In a 2022 ruling (July 20), it held that transmitting software from a foreign server to a device in Japan constituted “providing” the program invention. In a 2023 ruling (May 26), it found that transmitting system patent components from a foreign server to a device in Japan amounted to “manufacturing” and upheld infringement. In stark contrast to trade wars fought over rigid national borders, the expanding reach of patent rights across virtual borders is, to me, a personally fascinating development.

Korean trademark opposition period reducing to 30 days from 22 July 2025

Previously reported amendments to the Korean Trademark Act, including a shorter opposition period and increased punitive damages for willful trademark infringement, will come into effect from 22 July 2025. Given the impact this could have on decision-making processes, brand owners and agents who deal with Korea as part of their practice are advised to take careful note. Further details below. ▒  SHORTER OPPOSITION PERIOD (2 months → 30 days) [Applies to applications published after the amendment comes into effect] The current deadline for filing an opposition is 2 months from the publication date of the application, but this will be reduced to just 30 days. The opposition deadline itself cannot be extended. However, per existing practice, it will still be possible to file a formal notice of opposition to meet the deadline, and substantiate the grounds for opposition via submission of a supplemental brief within a further 30 days. (The later submission deadline for the supplemental brief can usually be extended for up to 60 days for national applications, but not for Madrid applications.) The change is part of KIPO’s efforts to reduce the timeframe for trademark applications achieving registration.  While good news for applicants, who can expect their applications to register slightly quicker than before, any party who may wish to oppose the registration of a trademark application will have less time to make such a decision, so watch service notifications and the like will need to be reviewed and acted on more urgently.   ▒  INCREASED PUNITIVE DAMAGES (3x → 5x) [Applies to acts of infringement which occur after the amendment comes into effect] The current Trademark Act allows for up to 3x damages in cases of willful/intentional acts of infringement. This will increase to up to 5x punitive damages.  The increase to quintuple damages aims to further discourage willful/intentional violations of trademark rights through higher financial consequences, as well as offer more reasonable compensation for trademark owners who may have difficulty precisely quantifying the actual damages that have been incurred.

Trademark law revision tackling importation of counterfeit goods comes into effect

An amendment to the Korean Trademark Act aimed at curbing the influx of counterfeit goods from overseas e-commerce platforms has come into effect as of May 27, 2025. ▒  Why is the change necessary In recent years, Korea has seen a sharp uptick in the number of counterfeit items crossing the border. In the Korea Customs Service (KCS)’s most recent report on IPR seizures, it is stated that a total of 83,892 trademark-infringing items were detected in 2023, representing a significant increase from figures which had hovered around the 30,000 mark between 2019-2021. This goes hand-in-hand with Korean consumers’ increasing use of overseas direct purchases (i.e. ordering from a seller based overseas and having the item shipped directly to you), with KCS data showing that the total number of overseas direct purchases increased from around 43 million in 2019, to over 96 million in 2022, and over 131 million in 2023.  Counterfeit goods not only damage brand value, but can also pose a direct threat to consumer health and safety. According to a KCS press release, around a quarter of the low-cost jewelry products purchased via popular Chinese e-commerce platforms that they tested were found to contain carcinogens that exceeded domestic safety standards. In another case, counterfeit vitamins led to a patient’s liver function values more than doubling.  In this respect, the Trademark Act was previously ambiguous on the question of whether items purchased directly from overseas by consumers in Korea met the definition of “use of a trademark” when the goods were for personal/non-commercial use.   Though there is legal interpretation (IP High Court Case No. 2011Heo4868) stating that when a Korean consumer purchases goods from a foreign website, ownership is transferred upon receipt in Korea, constituting a “transfer” and qualifying as trademark use under the previous Act, said existing provisions presuppose a commercial basis for trademark use, with personal purchases by individual consumers not clearly being applicable. Thus, it was widely considered necessary to establish a clearer legal basis for infringement in order for Customs and related agencies to take more effective action against the growing counterfeit problem.    ▒  What has changed? The amendment introduces a new clause under Article 2(1)-11 of the Trademark Act defining the act of supplying, via a delivery agent or other third party,  goods (or packages of goods) bearing a trademark which has been affixed abroad, as trademark use.   This revision will work in tandem with KCS’s seizure powers under the Customs Act, which authorizes Customs to suspend clearance when trademark infringement is established, thus giving Customs authorities a much clearer legal basis to block counterfeit imports even when the item was purchased directly by a consumer for their own personal use. It is not expected that individual consumers purchasing small quantities of counterfeit goods for personal use will be targeted under the revised law, which focuses on the act of “supplying” such goods, but this would not apply to larger-scale imports for the purpose of resale. (Note that this revision has no bearing on the parallel import of genuine goods, which is generally permitted under Korean law.)   ▒  Comments Customs authorities now having increased power to block counterfeit goods from entering the country will have a significant impact on border enforcement, which had become challenging to manage in the face of ever-increasing cross-border e-commerce. This will result in stronger protections for brand owners and also address consumer health concerns.  With this development, now is a good time for brand owners to review their Korean trademark portfolio and consider actively recording their rights with Korean Customs, particularly for any marks which are subject to counterfeiting. The customs recordal system, under which brand guidelines and enforcement information can also be provided as reference materials, aims to improve the effectiveness of border seizures and will be bolstered by the now-expanded definition of trademark use.   Written by Jonathan Masters and Sang-eun Shin
