Gore, Pella and Andersen Reach Settlement

October 6, 2009

Andersen Corp. has agreed to dismiss a patent infringement lawsuit against W. L. Gore & Associates and Pella Corp. Under what is described as a mutually satisfactory settlement, Andersen has granted Gore a license to practice certain Andersen patents. Pella may also continue to sell its VividView screening material purchased from Gore under the license. Terms of the settlement remain confidential.

Andersen originally filed suit against Gore and Pella in April 2007. Andersen charged that VividView high-transparency screens offered on Pella products, and manufactured by Gore, violated its patents associated with the development of Andersen's TruScene invisible window screens. None of the companies offered comment on the case at the time.

In reporting on the settlement, Andersen explains that its TruSence product is made with a virtually invisible, stainless steel screen material that provides clearer views and greater airflow. The insect screens are also said to practically disappear in a window and not detract from the beauty of the home.

On the market since 2004, Gore's inLighten screens are made with an ultra-fine fluoropolymer material that makes the insect screen virtually invisible, significantly improving the view, officials report. The screens are now offered by several window manufacturers with new windows, as well as direct to homeowners and residential contractors online in the form of screen rolls or custom-made framed insect screens.
