[Chosun Ilbo] “‘Coway Ice Water Purifier’ Did Not Infringe ChungHo’s Patent—Final Ruling After 11 Years”
On May 15, 2025, Chosun Ilbo published an article highlighting the achievements of Lee & Ko’s Intellectual Property Practice Group in the long-running patent dispute between Coway and ChungHo. According to the article, the Supreme Court’s Third Division upheld the appellate court’s decision, thereby conclusively rejecting ChungHo’s claims of patent infringement and damages against Coway. This final ruling affirms Coway’s victory, with Lee & Ko representing Coway in the appellate court and the Supreme Court. The article explained that the court of first instance initially found Coway liable for patent infringement, ordering the company to pay KRW 10 billion to ChungHo and to destroy the infringing products. However, the appellate court subsequently overturned this decision, ruling in favor of Coway. The appellate court determined that the essence of ChungHo’s patent was the process of making ice directly from pre-cooled water, while Coway’s product made ice using water at various temperatures. The court also noted significant differences between key components of the two products. The article continued, “The Supreme Court also found that the appellate court’s decision was correct,” adding, “Coway represented by Lee & Ko ultimately prevailed in the 11-year patent infringement lawsuit against ChungHo over ice water purifiers.”
