Oregon Improvement Company v. Excelsior Coal Company
Submitted November 11, 1889
Decided November 25, 1889
132 U.S. 215
Where a complaint in an action at law for the infringement of a reissued patent for an invention avers that the reissue is "for the same invention" as the original patent and the answer denies "each and every, all and singular, the allegations" of the complaint, it is error, on the trial, to exclude the original patent from being put in evidence by the defendant.
The case is stated in the opinion.
