after stating the case as above, delivered the opinion of the Court.
The petitioner raises a question of jurisdiction. It says that the suit does not arise under the patent laws of the United States, but is merely a suit on a contract like one for royalties under a license of which the District Court could not have jurisdiction because the parties are both citizens of the same State. To sustain this argument are cited

Bloomer
v.
McQuewan,
We do not think, however, that these clearly established principles sustain the next step in the reasoning of the counsel for the respondent and the Circuit Court of Appeals, which is that they make the mere right to exclude persons from the making, using and vending of an invention such an interest in a patent that it can be assigned. It ignores the indispensable condition of the granting and establishment of a patent right and patent property that the patentee shall have himself the common law right of making, using and vending the invention. The sole reason and purpose of the constitutional grant to Congress to enact patent laws is to promote the progress of science and useful arts by securing for limited times to inventors the exclusive right to their respective discoveries. Article I, § 8, clause 8. In pursuance thereof, § 4886, Rev. Stats., as amended, 29 Stat. 692, provides that any person who has invented or discovered any new and useful art, machine, manufacture or composition of matter or any new or useful improvements thereof, upon certain conditions not important here, may obtain a pat
The error in the position of the respondent and the court below is in a failure to distinguish between the property or title or interest in a patent capable of assignment and the chief incident of that property, title or interest, an incident which can only pass by assignment when attached to the right to make, use and vend. It is the fact that the patentee has invented or discovered something useful and thus has the common law right to make, use and vend it himself which induces the Government to clothe him with power to exclude everyone else from malting, using or vending it. In other words, the patent confers on such common law right the incident of exclusive enjoyment and it is the common law right with this incident which a patentee or an assignee must have. That is the implication of the descriptive words of the grant “ the exclusive right to make, use and vend the invention.” The Government is not granting the common law right to make, use and vend, but it is granting the incident of exclusive ownership of that common law right, which can not be enjoyed save with the common law right.
Dealing with the question of patent assignments under the laws of the United States, Mr. Justice Gray, in
Waterman
v.
Mackenzie,
“ The monopoly thus granted is one entire thing, and cannot be divided into parts, except as authorized by those laws. The patentee or his assigns may, by instrument in writing, assign, grant and convey, either, 1st, the whole patent, comprising the exclusive right to make, use and vend the invention throughout the United States; or, 2d, an undivided part or share of. that exclusive right; or, 3d, the exclusive right under the patent within and throughout a specified part of the United States, Rev. Stat. § 4898. A transfer of either of these three kinds of interests is an assignment, properly speaking, and vests in the assignee a title in so much of the patent itself, with a right to sue infringers; in the second case, jointly with the assignor; in the first and third cases, in the name of the assignee alone. Any assignment or transfer, short of one of these, is a mere license, giving the licensee no title in the patent, and no right to sue at law in his own name for an infringement. Rev. Stat. § 4919; Gayler v. Wilder,10 How. 477 , 494, 495; Moore v. Marsh,7 Wall. 515 .”
The learned Justice then proceeds (page 256) to give examples of what would and would not constitute an assignment. A grant of an exclusive right to make, use and vend two patented machines within a certain district, he points out, citing

Patterson
v.
Kentucky,
For the reasons given, we think the attempted assignment in this case carried no part of the title to the patent or interest in it and therefore conferred no right to sue for damages for infringement of the patent after the execution of the instrument.
The remaining question is whether the instrument relied on by the plaintiff below gave it the right to sue in its own name in this case for damages for past infringements. We think not.
The plaintiff below could not bring such a suit for past infringements without joining with it the owner of the
“ The monopoly did not exist at common law, and the rights, therefore, which may be exercised under it cannot be regulated by the rules of the common law. It is created by the act of Congress; and no rights can be acquired in it unless authorized by statute, and in the manner the statute prescribes.”
The law as to who should bring a suit at law for damages by infringement of a patent is clearly and correctly stated in III Robinson on Patents, § 937, as follows:
“ With a single exception the plaintiff in an action at law must be the person or persons in whom the legal title to the patent resided at the time of the infringement. An infringement is an invasion of the monopoly created by the patent, and the law which defines and authorizes this monopoly confers only upon its legal owners the right to institute proceedings for its violation. These owners are the patentee, his assignee, his grantee, or hispersonal representatives; and none but these are able to maintain an action for infringement in a court of law. Moreover, the injury inflicted by an act of infringement falls upon the individual who owns the monopoly at the date of the infringement. It does not affect former owners whose.interest had terminated before the infringement was committed, nor does it so directly prejudice a future owner that the law can recognize his loss and give him a pecuniary redress. Hence the plaintiff must not only have a legal title to the patent, but must have also been its owner at the time of the infringement. The exception above referred to arises where an assignment of a patent is coupled with an assignment-of a right of action for past infringements. In this' case the present owner of the monopoly may institute proceedings for its violation during the ownership of his assignor as well as for infringements committed since the transfer of the title to himself.”

Moore
v.
Marsh,
“And such damages may be recovered by action on the case, in any court of competent jurisdiction, to be brought in the name or names of the person or, persons interested, whether as patentees, assignees, or as grantees of the exclusive right within and throughout a specified part of the United States.”
The neat issue in that case was whether “ the name or names of the person or persons interested ” meant the person interested when the infringement took place or when the suit was brought. The Court held that it meant the person who was patentee, assignee, or grantee when
The question before him was whether the vendee and assignee of a receiver appointed by a state court of New York in proceedings supplementary to execution on a judgment against a debtor whose assets included a patent right and who was directed by the court to convey the same to the receiver but did not do so, could sue for damages for infringement of the patent occurring before the receivership. After saying that under the law of 1836 and under the Revised Statutes in which the sections of that law were embodied, no one could bring a suit either at law or in equity for infringement of a patent in his own name alone unless he were patentee, assignee, or grantee, the Judge continues:
“A claim to recover profits or damages for past infringement can not be severed from the title by assignment or grant, so as to give a right of action for such claim, in disregard of the statute. The profits or damages for infringement cannot be sued for except on the basis of title as patentee, or as such assignee or grantee, to the whole or a part of the patent, and not on the basis merely of the assignment of a right to a claim for profits and damages, severed from such title.' Therefore, if, in the present case, no such assignment or grant has been made to the defendants as the statute contemplates, they could not bring suit, in their own names, under the assignment made to them, to recover any claims, profits or damages for infringement, which belonged to Gordon, [i. e., the pat-entee], nor can they use the assignment as a defence against any such claims existing against themselves in favor of Gordon. In this case there has been no assignment éxecuted by Gordon.”

v.
Coker,
The sole exception to the rule that only he who is the owner of the patent at the time of the infringement can sue for damages, to which Professor Robinson refers, is when such owner assigns the patent and also the claim for past infringements to the same person. In such a case, as the title and ownership of the claims are united, it is held that the owner may sue.
