from Bouvier's Law Dictionary, Revised 6th Ed (1856)
INVENTION. A contrivance; a discovery. It is in this sense this word is used 
in the patent laws of the United States. 17 Pet. 228; S. C. 1 How. U. S. 
202. It signifies not something which has been found ready made, but 
something which, in consequence of art or accident, has been formed; for the 
invention must relate to some new or useful art, machine, manufacture, or 
composition of matter, not before known or used by others. Act of July 4, 
1836, 4 Sharsw. continuation of Story's L. U.S. 2506; 1 Mason, R. 302; 4 
Wash. C. C. R. 9. Vide Patent. By invention, the civilians understand the 
finding of some things which had not been lost; they must either have 
abandoned, or they must have never belonged to any one, as a pearl found on 
the sea shore. Lec. Elem Sec.  350.
