SEOUL, SOUTH KOREA (Feb. 28, 4:30 p.m. ET) — LG Chem Ltd. has prevailed in a Korean lawsuit in which Dow Chemical Co. claimed violations of technology used to make ethylene-based elastomers.
Midland, Mich.-based Dow had claimed that Seoul-based LG had violated intellectual property rights on metallocene catalyst technology used to make the materials. The decision was made Feb. 8 in Seoul Central District Court.
In a statement, Dow officials said the firm “is disappointed by the decision ... [and] Dow believes that the District Court's decision is improper and not supported by the facts or Korean patent law.”
The firm “will now consider its options for appealing the District Court's decision.” Officials added that Dow “has confidence that the decision will be set aside on appeal” and that the firm “will continue to vigorously protect and enforce its intellectual property rights.”
Dow uses the technology to make such products as Engage-brand polyolefin elastomers. Prior to the District Court's decision, key claims from Dow's patent were held valid by the Intellectual Property Tribunal of the Korean Intellectual Property Office, according to the Dow statement.
Both LG Chem and Dow are global producers of plastics and specialty chemicals.
