DSM Dyneema Files Patent Lawsuit against Chinese Company

20 January 2006

DSM Dyneema, the inventor and manufacturer of Dyneema, has filed a patent-infringement lawsuit against Hangzhou Pivot International Co. Ltd., of Hangzhou, Zhejiang Province, China.

Prior to the filing, DSM Dyneema obtained authorization to seize merchandise, including fibre, rope and finished articles, exhibited by Hangzhou Pivot at the Milipol 2005 exhibition on state security in Paris.

The lawsuit asks the court to establish and confirm its findings that this merchandise infringes on DSM Dyneema patents, and to forbid the sale or offering of these polyethylene-based, high-performance fibres by Hangzhou Pivot. DSM Dyneema is also seeking recall of the infringing products sold, as well as damages and other corrective measures.

According to Christophe Dardel, president of DSM Dyneema, “We have taken this action to protect our firm from those who unlawfully try to copy our unique fibre technology, as well as to secure a level playing field for companies developing and manufacturing applications on the basis of polyethylene-based high performance fibers. It is our policy to actively protect our intellectual property rights.”

DSM Dyneema protects its technology by applying for patent protection in different countries and regions. It has filed several patents in the field of high-performance polyethylene (HPPE) fibres and their applications. The company monitors potential infringements on an ongoing basis, and takes action against manufacturers, sellers and users of infringing products – whether fibres or end products.

In 2004 DSM Dyneema obtained a verdict from the District Court of The Hague in the Netherlands, who confirmed the infringing nature of high-performance fibres offered by another Chinese company, CEN International Trading Company, and ordered the latter to stop further sales of such infringing material. DSM Dyneema is confident the Court of Paris will rule in favour of DSM.
