SINGAPORE (ICIS)--LG Chem has won a lawsuit regarding the production of ethylene-based elastomers against US-based Dow Chemical, the South Korean producer said on Thursday.

Dow took legal action against the South Korean chemicals maker in December 2009, after it claimed LG Chem violated its patent right for the production of ethylene-based elastomers, according to a company source.

The Seoul Central District Court earlier in February ruled in favour of LG Chem’s independent know-how in the production of elastomers, the source said without elaborating further.

LG Chem in 1999 secured its unique technology for a metallocene catalyst that is the primary ingredient in the production of elastomers, the company said in a statement on Thursday.

The company currently produces 90,000 tonnes/year of elastomers, it said.

Only four companies, including LG Chem, are in possession of the key manufacturing technology worldwide that is required for making ethylene-based elastomers, according to the firm.
