SHANGHAI (Nov. 30) — Chinese chemical company Sinorgchem Co. said it has reduced the European market price for the rubber antioxidant 6PPD to under $3,000 per metric ton.
Sinorgchem said it cut prices on rubber antidegradants worldwide through production efficiencies, cost control and advantages it claims to have over its competitors in proprietary technology and trade secrets.
The company is appealing in federal appeals court the International Trade Commission ruling last July barring the company from selling 6PPD and its feedstock 4-ADPA in the U.S., on the grounds that it is violating the patents of Flexsys America L.P. The appeals brief is due to Federal Circuit appeals court in late December, said Manni Li, a Washington attorney representing Sinorgchem.
Meanwhile, Flexsys is continuing its $20 million patent infringement case in Cleveland federal district court against Sinorgchem, Kumho Tire USA Inc., Kumho Tire Co. Inc. and Kumho Korea Petrochemical Co. Ltd.
The firm said it has settled with another defendant, Sovereign Chemical Co. The terms of the settlement weren´t disclosed.
