In the final instance,  DSM Dyneema has won a protracted patent challenge against publicly held FMS Enterprises Migun of Tel Aviv. The firm had attempted to block the Dutch manufacturer of Dyneema, claimed to be the world’s strongest fiber, from obtaining a patent for the product in Israel.

An Israeli district court has now upheld an earlier decision of the Israeli Patent Office dismissing FMS’ claims.

DSM said the decision clears the way for the grant of a patent to Dyneema for the ultra-high molecular weight polyethylene (UHMWPE) fiber that specifies the amount of solvent to be used and acknowledges its rights to the relevant production technology. The fibers are claimed to improve the performance of end-use applications including ropes and ballistic-resistant products.

The Israeli decision is in-line with the grant of corresponding patents to DSM Dyneema in other global jurisdictions, such as the US, China and Europe, said Golnar Motahari Pour, president of the DSM subsidiary.

“Innovation and patents are cornerstones of DSM Dyneema’s business strategy,” Motahari Pour said, adding that the company has” consistently and rigorously defended its intellectual property on many occasions, and will continue to do so.”
