In the '7-Year Ice Water Purifier Patent Dispute,' Cheongho Nice Wins Against Coway

[Asia Economy Reporter Seongpil Cho] In the patent dispute over the water purifier cold-hot water system that can provide ice and cold water simultaneously, Cheongho Nice won against Coway.

According to Yonhap News on the 21st, the Patent Court Division 2 (Chief Judge Sangwoo Kim) dismissed the plaintiff's claim in the invalidation lawsuit filed by Coway against Cheongho Nice. The court stated, "There are technical differences that a general technician cannot easily imitate or overcome, and in some elements, the specific configuration and operation method differ from prior inventions."

Earlier, Cheongho Nice filed a patent infringement lawsuit against Coway, claiming that Coway released a product similar to its "cold-hot water system and device that can produce ice and cold water simultaneously using an evaporator."

In response, a Coway representative said, "This ruling concerns the 'invalidity' of Cheongho's patent and is unrelated to whether Coway infringed on Cheongho's patent," adding, "This lawsuit pertains to a water purifier discontinued in 2012 and does not affect our business."

They further stated, "We plan to actively consider response measures, including whether to appeal to the Supreme Court, after reviewing the judgment."
