composition of matter

Patents. A patentable compound of material composed of two or more different substances; a product containing two or more substances, including all composite articles, whether resulting from chemical union or from mechanical mixture, and whether the substances are gases, fluids, powders, or solids."[A] composition of matter describes what most people imagine to be the goal of the typical laboratory inventor, since it is usually a new chemical invention, although it can be any composition of materials, not limited solely to chemicals."
