Parrot v. Farnsworth

1 Brayt. 174

Opinion

IN an action of assumpsit, on a note of hand, the defendant may avoid the note, by shewing in evidence, under the general issue, that the note was given for a pretended patent righit which was void, on the ground of its not having been an original invention ; although a deed, with covenant, was made by plaintiff to defendant, conveying the patent right, and although the patent remains unrepealed.
