This portfolio constitutes a unique opportunity for buyers wanting to acquire a strategic (offensive and defensive) position in key growth areas, or for institutional buyers wanting to monetize this portfolio though licensing programs. The object of the patents offered for sale is an integrated frame, cover and adjustment system for constructing the top of manholes and utility vaults that is made from structural, elastomeric solution that is corrosion proof; leak proof; and unbreakable. It has been field tested in one of the harshest road environments on earth for over 10 years. Extensive lab tests, in addition to punishing traffic and weather, have confirmed that this is the “best in class” solution for collection systems and utility structures. (There are over 20 million collection system manholes and over 5 million utility vaults in North America alone). Potential applications also include catch basins and retail petroleum manholes.
