composition of matter

Patents. One of the five types of patentable statutory subject matter, consisting of com-binations of natural elements whether resulting from chemical union or from mechanical mixture, and whether the substances are gases, fluids, powders, or solids.

• This classification includes chemical compounds such as drugs and fuels, physical products such as plastics and particleboard, and new life forms made by genetic engineering. Its subject matter is always the substance itself, rather than the form or shape. — Often shortened to composition. [Cases: Patents 14. C.J.S. Patents § 22.]
