Patent decision goes DSM's way

30/05/2008
The United States district court for the northern district of Texas has found that Texas-based  firm Armour USA has infringed DSM’s  registered trademarks Dyneema and Dyneema Purity by using the brand name Unima in connection with products it was offering for sale. As a result, Netherlands-based DSM can prevent Armor USA from selling infringing products comprising polyethylene fibre on the US market and Armor  has agreed to stop infringing the patent and to stop using the brand name Unima or any other brand name similar to DSM’s registered trademarks.

The judgment in favour of DSM is its third in a row after earlier positive judgments in the Netherlands and France in 2004 and 2006, respectively.

Super strong polyethylene Dyneema fibre is light enough to float on water but is said to be 15 times stronger than quality steel and up to 40% stronger than aramid fibres. It is used in diverse applications including bullet-resistant armour and clothing, ropes, cables and nets in fishing, safety gloves for the metalworking industry, and fine yarns for the sporting goods and medical sectors.
