Finck v. Gilman Bros. Co.

HINCKS, Chief Justice.

This is an action alleging infringement of Finck patent No. 2,098,138 which, in general, covers a system of insulation by means of heat-reflective paper attached either to wall areas or an insulating blanket. This heat-reflective paper is of two types: metal-lised paper, and paper covered with an aluminum foil. The alleged infringement by defendant is the manufacture and sale of a “fabricated blanket insulating material having on at least one side thereof a layer of paper coated with heat-reflective material and specifically with aluminum foil.”
