North American Green Settles Patent Infringement Lawsuit Against Colbond

Evansville, Ind. – North American Green recently settled its second patent infringement lawsuit against Colbond relating to North American Green’s U.S. “Reinforced Composite Matting” Patent #5,849,645. The patent covers various aspects of the technology embodied in North American Green's Vmax3 line of composite turf reinforcement mats (SC250, C350 and P550).

In the first lawsuit settled in 2000, a Federal District Court judged North American Green’s Vmax3 Patent to be valid. Colbond agreed and the District Court ordered Colbond to cease manufacturing and selling certain of its composite turf reinforcement mat products.

North American Green filed a second lawsuit in 2004 against Colbond and its new Enkamat II composite product. Colbond insisted that the construction of this new product fell outside the scope of the 2000 consent judgment. North American Green agreed and granted Colbond a limited, non-exclusive license to manufacture and sell certain composite mats not covered by the original consent judgment. The license is subject to various conditions, including a restriction that the product not have two or more layers stitched together.
