Flexsys Drops Appeal Against Kumho

Filed under: Rubber Chemicals — Notch @ 12:55 pm

According to Rubber & Plastics News (subscription required), Flexsys Americas L.P. has dropped an appeal of its patent infringement lawsuit before the Supreme Court of South Korea. The suit was filed in April 2004 and alleged that Korea Kumho Petrochemical Co. Ltd. had violated Flexsys’ patents for the manufacturing of 4-ADPA and its derivative, the antidegradant 6PPD.

In November 2008, the US ITC ruled in favor of Korea Kumho Petrochemical when it terminated an investigation into the alleged violations initiated by Flexsys America on May 12, 2008.

Here is a press release from Korea Kumho on that decision.
