By the contracts involved in this suit the plaintiffs and their assignor purported to purchase of the defendant an interest in a patent. They claim to have discovered later that the defendant bad no title or interest in such patent, and they aver that their signatures to the contracts were obtained by false representations. Plaintiffs’ action was brought in the first instance as for damages. The defendant pleaded an equitable defense, and upon bis motion the case was transferred to the equity side. Thereafter, by various amendments to their petition, the plaintiffs asked to recover back their purchase money as having been paid without consideration. The defendant filed a counter claim for $200 upon a promissory note of the plaintiffs, being the unpaid part of the purchase money. In reply to such counterclaim the plaintiffs pleaded the same facts as above stated as a defense thereto, and tendered return of all property received and pleaded rescission. The pleadings are not in model form, but the substance of the issue as made is that plaintiffs declare upon a rescission of the contract as one having been entered into through false representation, and they ask to recover back the consideration paid thereon.
Under'one of tbe contracts referred to, the'plaintiffs purported to purchase said patent to tbe extent of its exclusive use for tbe county of Audubon, Iowa. Under tbe other, one Oathout, plaintiffs’ assignor, purported to purchase tbe same to tbe extent of its exclusive use for the county of Oass. Tbe following is a copy of the' Oathout contract:
A similar contract was entered into with the plaintiffs for Audubon county. The false representation charged is that the defendant falsely represented that he “had the sole control of said letters patent and all rights under the same in the state of Iowa.” One Kobertson was the patentee and real owner of said patent. Whatever right Alexander had was acquired under the following written contract with Robertson:
This article of agreement., made and entered into this
Turning now to the contract entered into between Alexander and the patentee, it is the contention of appellee that this contract does not purport to convey any interest in the patent, and that it only purports to give to Alexander the management of the “manufacture and sale” of the product to be produced 'under the patent. He may thereunder sell, not the patent, but the “stock waterer” and the “pressure valve.” He may sell the “golden eggs,” but not the “goose.” We think it must be said that under this contract Alexander obtained only a license. The contract did not amount to an assignment or transfer of the patent itself, either in whole or in part. Gayler v. Wilder, 51 U. S. (10 How.) 477 (13 L. Ed. 504); Mitchell v. Hawley, 83 U. S. (16 Wall.) 544 (21 L. Ed. 322); Hayward v. Andrews, 106 U. S. 672 (1 Sup. Ct. 544, 27 L. Ed. 271); Oliver v. Rumford, 109 U. S. 75 (3 Sup. Ct. 61, 27 L. Ed. 862).
That Alexander made the representation complained of is made to appear in the recitals of the contracts themselves. Oral evidence to the same effect is contained in the record. The representation was a material one. The rights acquired under a mere license are materially different in their nature from those acquired by an assignment of an interest in the patent itself. ' This is particularly so as to the right of transfer or sale of the subject-matter. The falsity of representation complained of, therefore, is sufficient ground to entitle the plaintiff to a rescission in equity regardless of any fraudulent intent on the part of Alexander, unless the right has been lost by reason of some of the affirmative
