DSM Protective Materials successfully defends patent related to Dyneema® Diamond Technology for the third time in China

June 2022

DSM Protective Materials, the inventor and manufacturer of Dyneema®, the world’s strongest fiber™, today confirmed the third successful defense of a patent for Dyneema® Diamond Technology in China, extending its positive track record in intellectual property (IP) cases. All three times, the validity of the patent has been confirmed in both administrative and legal proceedings.

Gloves made with Dyneema® Diamond Technology benefit from a single yarn solution that is thinner than conventional fibers – delivering enhanced cut resistance without glass, basalt, or steel fiber reinforcements. The technology’s patent protects against the unauthorized use of Dyneema® Diamond Technology, including the act of making, using, offering for sale, selling, or importing the fiber or subsequent products containing it, such as cut-resistant gloves and sleeves. Unauthorized use constitutes an infringement of the patent and can be subject to legal consequences, such as injunction and compensation. In addition to the Chinese patent, DSM Protective Materials has counterpart patents granted in the United States, as well as countries in Europe and Asia Pacific, offering the same level of protection.

“Dyneema® is born from science,” says Marcio Manique, Global Business Director, DSM Protective Materials. “Our scientific expertise in advanced materials is the foundation of our leadership – which, once again, has been confirmed in the successful patent defense of Dyneema® Diamond Technology. We believe our enduring market success is achieved through direct collaboration with our customers to provide unmatched levels of performance and protection for end-use applications made with Dyneema®. That is why we have a no-tolerance policy when it comes to infringements on our intellectual property and vehemently defend our position; we have a responsibility to our customers to defend the innovations and IP-protected technology platforms made possible with Dyneema®.”

DSM Protective Materials maintains its global track record of growing innovative technology platforms and long-term partnerships with leading industry partners with IP protection as the cornerstone of our continued success.
