MANUFACTURE. This word is used in the English and American patent laws. This term includes two classes of things; first, all machinery which is to be used and is not the object of sale; and, secondly, substances (such, for example, as medicines) formed by chemical processes, when the vendible substance is the thing produced, and that which operates preserves no permanent form. In the first class, the machine, and, in the second the substance produced, is the subject of the patent. 2 H. Bl. 492. See 8 T. R. 99; 2 B. & A. 349; Day. Pat.
