This is an application for a preliminary injunction to restrain the defendant from infringing letters patent No. 138,243, issued to John Gates for certain improvements-in lubricators for steam-engines. It is opposed solely on the ground that complainant has no such right and title as will authorize him to sue in his own name. The patent has been adjudicated upon, and the very question now raised answered in Siebert Co. v. Phillips Co., 10 Fed. Rep. 677. In that case Judge Lowell, construing the evidence of plaintiff’s title, uses this language:
“The assignment to the plaintiff! was made an assignment, rather than a license, in order that they might sue in their own names — so the contracts recite; but there is no legal objection to this: the motive is not material, and, the whole legal title being in the plaintiffs, they may maintain suit without joining the patentee.”
This decision, based on the same facts as those here presented, should ordinarily be controlling. Defendant, however, seeks to avoid that result by contending — First, that the former suit was a collusive one; and, second, that the instruments were not carefully considered, and that the learned judge was in error as to their effect, as is indicated in a later decision of his in Wilson v. Chickering, 14 Fed. Rep. 917.
The first contention is wholly unsupported by proof. The only affidavit submitted is one on information and belief, in which the affiant sets forth neither the sources of his information nor the grounds of his belief, except by affixing to his affidavit a clipping from a western newspaper. It need not, therefore, be considered.
*791There is nothing in the later decision of Judge Lowell inconsistent with the view's expressed by him in the case reported in 10 Fed. Rep. In Wilson v. Chickering, the patentee “licensed and empowered plaintiff to manufacture for the term of ten years, * * * and to sell the same; but in case of plaintiff’s bankruptcy, the license shall end.” In the present suit, the conveyance under which plaintiff claims title, so far as the granting part is concerned, is in the following words:
“The party of the first part has sold, assigned, and transferred, and by these presents does sell, assign, and transfer, to the party of the second part, all his right, title, and interest in and to the said improvements as secured to him by letters patent aforesaid, for, to, and in all parts of the United States and territories lying east of the Rocky Mountains; * * * the-same to be held and enjoyed by the said party of the second part within and throughout the above-specified territory, but not elsewhere, for his own use and behoof, to the end of tlxe term for which said letters patent were granted.”
The interpretation of patent conveyances, like that of all other written instruments, is to be according to the intent of the parties as evidenced by the words used. No particular form is required, although there must be some operative words expressing at least an intent to assign in order to constitute an assignment. Campbell v. James, 18 Blatchf. 107, 2 Fed. Rep. 388.
It seems clear from an examination of the foots in the two cases before Judge Lowell that in the piano case the intention was to reserve to the grantor everything except the right to manufacture and sell for a term of 10 years, while in the oil-cup case the grantor intended to transfer all that he had, except, perhaps, the right to an extension. There seems no reason, therefore, why the decision of Judge Lowell construing the very instruments now before the court should not be followed on this application for a preliminary injunction, and the plaintiff’s motion is therefore granted.
