after stating the case, delivered the opinion of the court.
■ As a result of the findings of fact, the Circuit Court held that the sale and delivery of the pipe by .the defendant were made at Bay City, Michigan, but that, in view of the decision of this court in
Adams
v. Burke,
We understand that to be the true interpretation of the decision in Adams v. Burke. It is said in the opinion in that case, that when the patentee, or the person having his rights, *362 sells a instrument whose sole value is in its use, he receives the consideration for its use and parts with the right to restrict that use; that the patentee, or his assignee, having in the act of sale received all the royalty or consideration which he claims for the use of his invention in that particular machine or instrument, it is open to the use of the purchaser without further restriction on account of the monopoly of the patentee;' that, although the right of the assignees of the coffin-lid patent to manufacture, to sell, and to use the coffin-lids was limited to the circle of ten miles around Boston, a purchaser from them of a single coffin acquired the right to use that coffin for the purpose for which all coffins are used; that, so far as the use of it was concerned, the patentee had received his consideration, and it was no longer within the monopoly of the patent; that it would be to engraft a limitation upon the right of use, not contemplated by the statute nor within the reason of the contract, to say thát. it could only be used within the ten-mile circle; and that, whatever might be the rule when patentees subdivided territorially their patents, as to the exclusive right to males or to sell within a limited territory, this court held that, in the class of machines or implements it had described, when they were once' lawfully made and sold, there was no restriction on their use to be implied, for the benefit of the patentee or his assignees or licensees.
The plaintiffs in error’ contend that the deqision in Adams v. Burke is not applicable to the present case; that in Adams v. Burke it was assumed that the patented coffin-lids were first lawfully sold to the purchaser, without condition or restriction, by assignees of the patent for the territory of Boston and vicinity; that then the question was presented 'whether, as an incident of such a lawful sale, the buyer could use outside of the limits of the territory of the assignees the article so lawfully purchased; that it was not shown in that case that the sellers sold the patented coffin-lids for use in other territory, or knew of, or had any interest in such use; that, in the case now before us, the lawfulness, as against the plaintiffs, of the alleged sale of the patented pipe by the defendant, in the actual circumstances of such sale, was contested, the claim of the plain *363 tiffs being that such, sale and the shipment thereunder, expressly for use within the territory of the plaintiffs, constituted an invasion of their rights and were unlawful as against the plaintiffs; and' that. actual sale, delivery, and acceptance of the pipe at Bay . City for actual use would be one thing, but a form of delivery at Bay City, with an acceptance at Hartford, and knowledge and intention on the part of the defendant that the sole use would be at Hartford, and shipments on that basis and understanding, would not constitute a lawful sale of the pipe at Bay City, as against the plaintiffs.
But' we are of opinion that the case of
Adams
v.
Burke
cannot be so limited; that the sale was a complete one at Bay City; and that neither the actual use of the pipes in Connecticut, or a knowledge on the part of the defendant that they were intended to be used there, can make him liable.
Adams
v. Burke, in the particular in question, is cited with approval by this court'in
Birdsell
v. Shaliol,
The authorities which are cited on the part of the plaintiffs', holding that where a person makes one element of a patented combination, with the intent that other persons shall supply the .other elements and thus complete the combination, he is guilty of infringement because he contributes to it, establish a doctrine applicable to the case of a naked infringer. But in the present case, the defendant was not such an infringer, because he had a right under the patent' to make, use, and vend the patented article in the State of Michigan, and the article was láwfully made and sold there. The pipes in question were not sold by the Hartford Steam Company in Connecticut, but were merely used there, and necessarily perished in the using.
It is easy for a patentee to protect himself and his assignees, when he conveys exclusive rights under the patent for particular territory. He can take care to bind every licensee or assignee, if he gives him the right to sell articles made under the patent, by imposing conditions which will prevent any other licensee or assignee from being interfered with. There *364 is no condition or restriction in the present case in the title of the defendant. He was the assignee and owner of the patent for the State of Michigan.
Judgment affirmed.
