Pattee Plow Co. v. Kingman, 129 U.S. 294 (1889)
Pattee Plow Co. v. Kingman
Argued November 16, 19, 1888
Decided February 4, 1889
129 U.S. 294
APPEAL FROM THE CIRCUIT COURT OF THE UNITED
STATES FOR THE EASTERN DISTRICT OF MISSOURI
The second claim of reissued letters patent No. 6080, granted to James H. Pattee, October 6, 1874, for improvements in cultivators, changes the first claim of the original patent (1) by omitting the plates B and (2) by the addition of the direct draft, and thus substantially enlarges the invention, and consequently is invalid.
The machines manufactured by the defendants do not infringe letters patent No. 174,684, granted to Thomas W. Kendall, March 14, 187f, for improvements in cultivators.
