Composition of matter

    0.04 sec.

COMPOSITION OF MATTER. In describing the subjects of patents, the Act of Congress of July 4, 1836, sect. 6, uses the words "composition of matter;" these words are usually applied to mixtures and chemical compositions, and in these cases it is enough that the compound is new. Both the composition and the mode of compounding may be considered as included in the invention, when the compound is new.
