DSM Dyneema successfully defends key patent against competitor challenge
European Patent Office rules after competitive opposition proceedings that DSM’s patent for high end pressed protective products is valid and will remain in force as granted
The Netherlands, 27 September 2016 - DSM Dyneema, inventor and manufacturer of Dyneema®, the world’s strongest fiber™, has again successfully defended a key patent from challenge before the European Patent Office (EPO) Opposition division. The company Teijin Aramid had challenged the EPO’s previous grant of DSM Dyneema’s European patent (EP1575758B), which covers pressed products based on specific improved Uni Directional (UD) systems, typically designed and used in high end armor applications such as helmets, inserts, and vehicle armor. DSM’s technology aims at pressed products with improved performance at higher temperatures, while still maintaining good performance at ambient temperature.
On September 15, 2016, DSM Dyneema addressed the challenge at an oral hearing in The Hague, the Netherlands. The EPO was convinced by DSM Dyneema’s arguments, and dismissed the opposition, concluding that the patent, covering one of DSM Dyneema’s key innovations, will be maintained as granted. As a result, the patent remains in force. The patent covers pressed products based on specific UD systems therewith protecting DSM and its customers’ products against unlawful copying.
“Innovation and the protection of our intellectual property through patents are the cornerstones of DSM Dyneema’s innovation strategy. This challenge shows that third parties recognise the quality and value of our patents, and we are pleased to have this quality reconfirmed by the European Patent Office”, said Golnar Motahari Pour, President of DSM Dyneema.
