Phil-Insul Corp. v. Airlite Plastics C0.

IntegraSpec’s 933 Patent originally issued in 1995 and underwent ex parte reexaminations before the Patent & Trademark Office in 2010 and 2014. The patent is directed to ICFs, which are expanded polystyrene foam blocks used as molds to cast concrete walls. The ICFs are stacked to form a hollow wall which is then filled with concrete. The ICFs remain in place after the concrete sets to serve as insulation for the building. The ICFs consist of two parallel foam panels that form sidewalls. The top and bottom edges of the sidewalls have interconnecting means used to connect one ICF to another when they are stacked. In an infringement action, the Federal Circuit affirmed summary judgment of noninfringement, based on a finding that IntegraSpec’s claims were precluded by a 2014 Federal Circuit decision based on the same claims.
