Letters patent—invalidity of—effect of, on agreement made Try assignees—Defeats in pleading.This case is like that of Hawks against the same defendants, argued at this term, in many respects. The additional facts which are important are, that Marston, the plaintiff, and Swett and others, the defendants, were the assignees of the alleged patent right of Elizabeth Hawks, by virtue of the assignment made by her in 1867, and of the second assignment made by her in 1870, after the surrender and re-issue. Being such owners in common, the defendants agreed with Marston that they should have the exclusive right, and that he should not license others.
In consideration of this, they agreed to pay him fifty cents for
It is not denied that the defendants have made stoves, to a certain number, which would be under the patent, if the patent were valid. The same questions as to the effect of the invalidity of the patent are raised, which were in the other case.
A question was made, whether this verbal contract was valid under the statute of frauds; and a similar question, whether it was valid under the patent laws; the contract being, as was claimed, in effect, an assignment of the patent, and not being in writing.
But without passing, upon these, I come to the important point,' which is, whether the plaintiff can recover these fees, when the letters patent have been declared void.
Most of what was said in the former opinion is applicable here. Marston was a defendant in the suit brought in the United States court by these defendants, in which the letters patent were declared to be void, and Mrs. Hawks was adjudged not to be the inventor. He had an opportunity there to contest the question of invalidity, and to urge that, as to himself, these defendants were estopped. He might have claimed (with what success it is unnecessary to say), that the decree should be so qualified as to preserve any rights between him and these defendants, arising out of their contract. But that was not done, and the decree must be conclusive.
The plaintiff in this action made some offers tending to show collusion by the defendants with Gloodfellow. But so far as these offers were of any weight, they were only an indirect attack on the decree in the United States court. If that alleged collusion was a good defense, it could have been shown in that suit.
It is urged by the plaintiff’s counsel that the ownership in common of the alleged patent right, prevents the defendants from averring its invalidity as a defense.
And the case of Kinsman v. Parkhurst,[4] is relied upon. In that case a patentee and an assignee of a part interest entered into
The only remaining question is ón the verdict directed for the. defendants on their counter-claim. The answer sets up that the plaintiff was indebted to the defendants for goods, wares and merchandise, sold and deliveréd, etc., since a certain date, in a certain sum, and asked judgment. The reply denied that the plaintiff was indebted to the defendants' for goods, wares and merchandise sold and ' delivered, etc., since that. date, in that sum, but admitted that there was a small sum due to the défendants, for goods, wares and merchandise, sold and delivered, etc., the amount of which the plaintiff does not know. It was claimed by the defendants that this was no denial. In strictness, this seems to be correct. To deny that one is indebted

The important matter evidently was the plaintiff’s claim, and this counter-claim was secondary. On the whole, therefore,' there is no reason to disturb the course which the case took on the trial.
The judgment and order appealed from should be affirmed.
Present — Learned, P. J., Boardman and Potter, JJ.
Judgment affirmed.
