Argued December 16-17, 1891
Decided February 29, 1892
143 U.S. 275
APPEAL FROM THE CIRCUIT COURT OF THE UNITED
STATES FOR THE NORTHERN DISTRICT OF IOWA
The invention secured to Joseph F. Glidden by letters patent No. 157,124, dated November 24, 1874, for an improvement in wire fences, involved invention, and the patent therefor is valid.
Courts incline to sustain a patent to the man who takes the final step in the invention which turns failure into success.
