INUREMENT

INVENTION. In patent law. The act or operation of finding out something new; the process of contriving and producing some thing not previously known or existing, by the exercise of independent investigation and experiment. Also the article or contriv ance or composition so invented. See Lei dersdorf v. Flint, 15 Fed. Cas. 260; Smith v. Nichols, 21 Wall. 118, 22 L. Ed. 566; Hol lister v. Manufacturing Co., 113 U. S. 72, 5 Sup. Ct. 717, 28 L. Ed. 901; Murphy Mfg. Co. v. Excelsior Car Roof Co. (C. C.) 70 Fed. 495. An "invention" differs from a "discovery." The former term is properly applicable to the contrivance and production of something that did not before exist; while discovery denotes the bringing into knowledge and use of some thing which, although it existed, was before un known. Thus, we speak of the "discovery" of the properties of light, electricity, etc., while the telescope and the electric motor are the results of the process of "invention." INVENTOR. One who finds out or con trives some new thing; one who devises some new art, manufacture, mechanical appliance, or process; one who invents a patentable con trivance. See Sparkman v. Higgins, 22 Fed. Cas. 879; Henderson v. Tompkins
