The patent in suit was U.S. Patent No. 8,936,847 titled “Metallized Polymeric Film Reflective Insulation Material,” is directed to metallized polymeric film reflective insulation materials.

Promethean had alleged direct infringement as well as inducement to infringement and contributory infringement by Reflectix.

Promethean has three pending infringement actions against TVM Building Products Inc., Energy Q LLC and Soprema Inc. (Canada).
