Designs 2025.09.29 published IPLEX 2 min read Incident Overview In the online shopping mall operation, products are often suddenly suspended due to reports of infringement of intellectual property rights ( patent, design right, trademark right). In particular, since the platform takes the claims of the rightholder first, it is often the case that the seller is unfairly harmed. This was a case in which the knee braces sold in Coupang were stopped on the basis of third-party design right registration. The suspension remained unresolved for an extended period, so the seller engaged IPLEX. The problem the seller faces. - Repeated product suspensions posed a risk to the entire account. - Account suspension could cause serious losses. - The product already has a history of selling on other platforms for more than one year Response Strategy IPLEX prepared a patent attorney's opinion and explanatory statement addressing the following grounds: The existence of nullity of registered design – confirmation of multiple sales and reviews from 2023 – lack of novelty (Design Protection Act Article 33 (1)) Entitlement to registration: evidence that the design was copied from an existing Chinese product raised issues under Article 3(1) of the Design Protection Act. Freely usable prior-art design: the widely known design could be used freely, supported by Supreme Court case 2016Hu878. Prior-user rights: sales before the filing date supported a statutory non-exclusive license under Article 100 of the Design Protection Act. In addition, we have enhanced the pressure effect by detailing the legal disadvantages that a claimant can receive, rather than simply asserting. result - Sales resumed within two days of submission of the opinion. - Coupang acknowledges the submitted evidence (sales history, reviews, overseas sales evidence, etc.) and legal basis - The seller returned to normal business promptly. News A right holder's complaint is not necessarily well founded. Evidence is key. A reasoned professional opinion can support the response. Prompt action helps minimize losses. Conclusion A sales suspension can affect any seller. Objective evidence and legal reasoning can support reinstatement.
