The European Patent Office has upheld a key patent held by DSM Dyneema covering its recently introduced Dyneema® Force Multiplier Technology. This radical innovation platform delivers game-changing materials for soft body armor and hard materials for helmets, vest inserts and vehicle armor. Armor made with Dyneema® Force Multiplier Technology is 30 percent lighter than current armor whilst providing the same level of ballistic protection.

DSM Dyneema’s patent EP1699954B1 had been opposed by another important western supplier of UHMWPE fiber. “We are very happy that the European Patent Office, after having heard both parties, has confirmed the validity of the patent,” says Yvonne Engelen, vice president marketing and sales at DSM Dyneema. “Dyneema® Force Multiplier Technology is a game-changer in the life protection field, it is the result of an important investment in research and development dating back over more than ten years by DSM Dyneema, and it is a confirmation that the massive body of knowledge we have built up in UHMWPE fiber and UD chemistry and production technology is unique.”

“The market introduction of this high-end platform has been highly successful, and we see substantial growth potential. The importance of Dyneema® Force Multiplier Technology has already been recognized by our customers and through various awards it has received.”

After this verdict, the intellectual property covered by the patent gives DSM Dyneema the confidence to move forward in exploiting the technology for the benefit of its customers in diverse markets. “Since filing this original patent, we have continued our innovation efforts and filed other patents relating to this technology platform,” Engelen adds.

Engelen says that the confirmed protection for Dyneema® Force Multiplier Technology and the newest generation of ultimate strength Dyneema® fibers means that DSM Dyneema customers can benefit from the protection of the unique products they source from the company. “It is natural that, with our ongoing innovations in the development and production of ultrahigh molecular weight polyethylene fiber, third parties will seek to contest our patents,” Engelen says. “The decision from the European Patent Office confirms the high quality of our innovations and patents.”


About DSM Dyneema

DSM Dyneema is the inventor and manufacturer of Ultra High Molecular Weight PolyEthylene (UHMWPE) fiber branded as Dyneema®, the world’s strongest fiber™. Dyneema® offers maximum strength combined with minimum weight. It is up to 15 times stronger than quality steel and up to 40% stronger than aramid fibers, both on weight for weight basis. Dyneema® fiber floats on water and is extremely durable and resistant to moisture, UV light and chemicals. The applications are therefore more or less unlimited. Dyneema® is an important component in ropes, cables and nets in the fishing, shipping and offshore industries. Dyneema® is also used in safety gloves for the metalworking industry and in fine yarns for applications in sporting goods and the medical sector. In addition, Dyneema® is also used in bullet resistant armor and clothing for police and military personnel.

UHMWPE fiber from DSM Dyneema is produced in Heerlen (The Netherlands) and in Greenville, North Carolina (U.S.A.). DSM Dyneema is also a partner in a high modulus polyethylene (HMPE) manufacturing joint venture in Japan. Further information on DSM Dyneema is available at
