ITW Dynatec vs. Nordson


Tuesday, April 24, 2012

On March 29, 2012 the District Court in Düsseldorf, Germany, (Docket No 4a O 20/11), rendered a first instance decision that certain processes performed with Nordson Sure Wrap Nozzles infringe the German part of European Patent  950436 B1 owned by Illinois Tool Works Inc. (ITW). The District Court also decided not to stay the proceeding until the Federal Patent Court has adjudicated the nullity action brought by subsidiaries of Nordson Corporation against this patent. Christof J. Schotten, Vice President/General Manager Worldwide of ITW Dynatec, a business unit of ITW, stated, “We are pleased that the German District Court has recognized the value of our intellectual property relating to dispensing hot melt adhesive onto a strand of elastic.”

This technology can be important in the manufacturing of baby diapers and adult incontinence products. The ITW Dynatec Omega™ SCS strand coating system utilizes this technology, and the company was seeking clarification of whether the use of the Nordson Sure Wrap product infringes its intellectual property.

ITW owns patents related to this technology in many other countries also.

 The decision is not final and can be appealed by Nordson.
