(cen.acs) --
Dow Chemical has lost the patent lawsuit it filed in 2009 in Seoul, South Korea,
against LG Chem. Dow claimed that the Korean firm had violated its intellectual
property rights on metallocene catalyst technology for producing ethylene-based
elastomers.
Dow is preparing to appeal the court’s ruling that its claim
has no legal basis. "Dow believes that the district court’s decision is
improper," a company statement says. Prior to this judgment, the statement adds,
"Dow’s patents were held valid by the Intellectual Property Tribunal of the
Korean Intellectual Property Office."
LG Chem counters that it
developed the technology on its own in 1999. The Korean firm opened a
90,000-metric-ton-per-year plant making use of the process in 2008.
