Metso, Finland, reports that it has reached an agreement with Airtherm Corp., USA, after an apparent patent infringement by Airtherm in a patent owned by Metso. The Metso product protected by this patent, Metso notes, is the so-called Advantage WetDust system, whereby dust in a paper and tissue making line is entrained into a dust collector where water is injected directly inside the dust collector.
According to Metso, Airtherm has agreed to discontinue any further sales of the wet dust collection system protected by Metso's patent. Airtherm has also agreed to pay for a one-time license for systems already sold.
The patent in question is U.S. Patent No. 6,176,898 issued in 2001, titled "Method and System for Collecting and Handling Dust in a Paper Machine Environment."
