HIGHEST EUROPEAN AUTHORITY UPHOLDS DSM DYNEEMA PATENT

Company Successfully Defends Its Patent for Panels Incorporating Dyneema® High-Performance Polyethylene Fiber

URMOND (NL), 8 December 2008 - DSM Dyneema, inventor and manufacturer of Dyneema®, the world’s strongest fiber®, has won a victory before the European Patent Office Boards of Appeal. The company received notification in November 2008 that it had successfully defended its patent for panels incorporating high-performance Dyneema® fiber against a challenge from Teijin Aramid (formerly Teijin Twaron), a Dutch supplier of rival fiber products. The panels made with Dyneema® are used in such applications as bullet-resistant vests and vehicle armor.

“We are pleased that Europe’s highest patent authority has affirmed the validity of this important patent. This decision reinforces the effectiveness of our patents in protecting our technological innovations. We will continue to pursue a strategy of rapid, targeted innovation and vigorous defence of our intellectual property in all markets and business segments in which we participate,” said Christophe Dardel, Business Group Director of DSM Dyneema.

The DSM Dyneema patent portfolio consists of well over 100 inventions protected by over 500 filed patents and patent applications worldwide, and is expanding all the time.

The panels, made with Dyneema®, patented by DSM Dyneema are vital components of innovative life protection systems, which provide superior anti-ballistic protection for both personnel and vehicles. With significant weight reduction vs. aramid, panels made with Dyneema® fiber increase comfort and wearability of protective clothing, and enhance the stability and speed of armored vehicles. On a weight-per-weight basis, Dyneema® is as much as 15 percent stronger than steel and up to 40 percent stronger than aramid fiber, with the added advantages of extreme durability and resistance to moisture, UV light and chemicals.
