Head Matter:
Moore v. Marsh.
Under the fourteenth section of the Patent Act of 1836, enacting that damages may be recovered by action on the case, to he brought in the name of the person “interested,” the original owner of the patent, who has afterwards sold his right, may recover for an infringement committed during the time that he was owner. The word “ interested,” means interested in the patent at the time when the infringement was committed.
Error to the Circuit Court for the Western District of Pennsylvania.
The eleyenth section of the Patent Act of 1886, relating to the.assignment of patents, thus enacts:
“ Every pátent shall be assignable in law either as to the whole interest, or any undivided part thereof, by any instrument in Avriting, which, assignment, and also every grant and conveyance of the exclusive right under any patent to make and use-, and to .grant to others'to make and’ use the-thing patented, within and throughout any specified' part or portion of the United,States, shall be recorded,” &e., &e.
And tbe fourteenth' section, which relates to damages in • suits,, brought' by the owners of patents, for infringement, says:
' “And such damages may be. recovered by action on the case, m any court1 of competent jurisdiction, to be. brought in the name or names of the person or persons interested, whether as patentees, assignees, of as grantees of 'the exclusive right within ' and throughout a specified part of the United States.”
This statute being in force, Moore, a patentee, brought suit in the court below, against Marsh, fdi infringement. Marsh pleaded that after the. date of the alleged .infringement, he Moore,-the patentee, bad sold and assigned an undivided half of the patent for the district where the infringement was alleged to Jiave 'been committed-. To this plea, Moore demurred. The court having sustained the demurrer, and judgment being given accordingly, the case was brought here by the patentee on appeal.
The general question therefore, was, whether a sale and assignment by a patentee of his patent right is, under the fourteenth section above quoted; a bar .to an action by him.to recover damages for an infringement committed before such sale and transfer ? In other words, whether the words of the statute “ name of the person interested,” meant, as the plea assumed, “ persons interested in the patent at the time when the suit was brought;” of meant, as the declaration assumed, interested at the tiihe when the cause of action accrued.
The case was-submitted on briefs.
Mr. iS. S. Fisher, for the patentee, appellant,
argued,- that the latter, or interested in the damages, was the plain meaning; that it would be unreasonable' and contrary to all analogies of the lqw, that a simple assignment of a patent-rigfit should carry with it the right to all previous damages, carry with it all the damages which had ever accrued to its former owners in the whole course of the patent’s, life, and from the date of the letters patent; that back damages were not a matter inherent in? sticking to, and inseparable from the patent, but were a matter which belonged to the owner in his individual right. And this natural view, he considered, was supported by the authority of this court in Dean v. Mason.
Messrs. Henry Baldwin, Jr., and W. Bakewell, contra,
argued, that the words of the fourteenth section of the statute, meant interested in the patent, and not interested in the damages; and that this was manifest—
1. By comparing this fourteenth section with the eleventh section above cited.
2. By the fact that licensees were excluded, though they were frequently the only parties interested in the damages, while the plaintiff in such cases is the party interested as patentee, assignee, or grantee of an exclusive right, and had no interest in the damages.
3. From the decisions (as the learned counsel interpreted them) of this court and of several of the,circuit eourts.
An opposite view, they contended, might lead to gross oppression. According to such view, a party who, in mistake as to his rights — and in these nice questions of mechanical principle, innocent mistake might well occur — may have infringed a patent during a number of years, is exposed at the end of the term' to .as many separate suits for infringement as.fhere have been separate'owners of the patent during the time he has been using it; and may have to defend against fifty separate actions brought by as many different plaintiffs for what has been a continuous act of user of the patented machine. Such a hardship could never be intended by Congress, and this court would not put a construction oh the act fraught with such oppressive consequences. This argument, ab inconvemmii, was considered a'sound one in this court (the counsel argued), in Gayler v. Wilder* where Taney, C. J. pressed it in behalf of the court, and by Mr. Justice Grier, in' Blanchard v. Eldridge, where speaking of the eleventh section of the act, he says that “ the act of Congress has not subjected even a pirate of the machine to fifty different suits by fifty several assignees, whose several interests might be affected.”
Dean v. Mason, relied on by Mr. Fisher (the counsel argued), did not apply. It was an assignment pendente lite, and moreover of a < mere license.

Opinion:
Mr. Justice CLIFFORD
delivered the opinion of the court.
Viewed in the light of the admitted facts, the only question in the ease'is whether the assignment by the plaintiff to a third person of an undivided half of the right, title,- and interest secured to him by his letters patent, subsequent to the alleged infringement, but before the commencement of his suit, is a bar to his claim to recover damages for such infringement.
Letters patent were granted to the plaintiff on the 18th of April, 1848, for a certain new and useful improvement in grain drills, in which it is alleged'that he is the original and first inventor of the improvement. Original patent .was for the term of fourteen years, but it was subsequently extended by the Commissioner of Patents for the term of seven years from and- after the expiration of the original term. Alleged defects-existed in the original specification, and in consequence thereof, the plaintiff*, on the 3d of February, 1863, surrendered the letters patent, and the' same were reissued to him in three new patents for separate and distinct parts of the invention for the unexpired portion of the original and extended terms of the patent.
Damages are claimed of the defendants for infringing the reissued letters patent from the day of the reissue to the 24th of February, 1865, as more fully set forth in the declaration.
Pleas to the declaration were, subsequently filed by the defendants, and the record shows that they gave due notice of certain special defences which they proposed to offer in evidence under the general issue, in pursuance of the act of Congress in such ease made and provided. Before the day for the. trial came, however, the parties filed an agreement waiving a jury and submitting the cause to the court, stipulating that the decision of the court should have' the same effect as the verdict of a.jury. Leave to amend was subse- • quently granted by the court to both parties.
Purport -of the amendment , to the declaration was, that the plaintiff was the sole owner of the letters patent for the county of Union, ,in the State of Pennsylvania, from the date of the reissued letters patent to tlfe 24th of February, 1865, and that the defendants had infringed the same throughout that period, by making and using the invention, and vending the same to others to be used without his license or consent.
Defendants filed another special plea, in which they alleged that the plaintiff, when he commenced his suit, was not the owner of the exclusive right secured in the reissued letters patent within any part of the United States; that in certain States and districts he had parted with all his interest in the patent; and that, on the said 24th of February, he assigned and transferred an undivided half of all the residue of his right, title, and interest in the same, and, therefore, that the-plaintiff had no right to bring this action in his own name, against the defendants. Plaintiff demurred to the plea, and the defendants joined in demurrer. Parties were heard, and the court rendered judgment for the defendants, and the plaintiff sued out this writ of error.
Conceded fact is, that the plaintiff was the. exclusive owner of the patent in the territorial district where the alleged infringement was committed, throughout the entire period of the infringement, as alleged in. the declaration. Express allegation of the declaration is to that effect, and, as the plea js in avoidance and contains no denial of the matters alleged in the declaration, they must be considered as ad mitted, unless the matters alleged in the' special plea are a sufficient answer to the action. •
Briefly stated, the matter alleged in avoidance of the right of the plaintiff to maintain the suit is, that he, before he commenced the suit, but subsequent to the infringement-? sold and assigned an undivided half of flis patent for the territorial district where the infringement was committed, to a third person.
• Patentees have -secured to them, by virtue of the letters patent granted to them, the full and exclusive right and liberty, for a .prescribed term, "of making and using, and vending to others to be used," their respective inventions or discoveries; aud, whenever their rights, as thus defined, are invaded by others, they áre entitled to an action on the case to recover actual damages as compensation for the injury.
Such damages may be recovered by action on the case in any Circuit 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, as already defined, within and throughout a specified part of the United States.
Assignees aud grantees,' as well as the patentee, may, under some circumstances, maintain an action on the case for an infringement, in their own name, as appears by the express words of the act of Congress. An assignee'is one who holds, by a valid assignment in writing, the whole interest of a patent, or any undivided part of such whole interest, throughout the United St^tes.
, Where the patentee has assigned his whqle interest, either before or after the patent is issue'd, the action must be brought in the name of the assignee, because he alone was interested in the patent at the time the infringement took place; but where the-assignment is of an undivided part of the patent, the action should be brought for every infringement committed subsequent to the assignment, in the joint names of. the patentee and assignee, as representing the entire interest.
Settled vieW- at o.ne time was, that the grantee of a territorial right, ,for a particular district, could not bring an action on.the-patent in his own' name; but the act of Congress having made him a party interested in the patent, it is now equally well settled that he may sue in his own name for invasion of the .patent in that territorial district, as no one1' else i's injured by any such infringement.
Both assignees and grantees have an interest in'the patent, but the terms are not synonymous, as used in the patent law.
> Grants, as well as assignments, must be in waiting, and they must convey the exclusive right, under the patent, to make and use, and vend to others to be used, the thing, patentéd, within'and throughout some specified district or portion of the United .States, and such right must be exclusive 'of the patentee, as well as of all others except the grantee. Suits for infringement in such districts, if committed subsequent to the grant, can only be brought in the name of the grantee, afs it is clear that no one /an maintain such an action until his rights have been invaded, nor .until he is interested, in the damages to be recovered.
Alleged infringement in this case was committed .in the county of Union, in the State of Pennsylvania, and the admitted fact is, that the plaintiff,.throughout the entire period of the infringement, w/as the sole owner of the exclusive right to make and use, and grant to others to make and use, the thing patented in that territorial district, by virtue of his originál title as patentee, having never assigned or granted any right, title, or interest, within that county.
Grant that these views are correct, and it is clear that unless -the plaintiff* can maintain the action there can be no redress, as it is too.plain for argument, that a subsequent -assignee or grantee can neither maintain an action in his own name, or be joined with the patentee in maintaining it for any infringement of theNexclusive right committed before he became interested in the patent. Undoubtedly the assignee thereafter stands in the place of the patentee, both as to right under the patent and future responsibility; but it is a great mistake to suppose that the assignment of a patent carries with it a transfer of the right to .damages for an infringement committed before such assignment.
Comment upon the cases cited, as supporting this proposition, is unnecessary, as it is clear to a demonstration that they give it no countenance whatever. Such a proposition finds no support in any decided case, nor in the act of Congress upon the subject.
True meaning of* the word interested, as employed in the last clause of the fourteenth section of the Patent Act, when properly understood and applied, is, that the right of action is given .to the person op persons owning the exclusive right at the time the -infringement is committed. Subsequent sale and transfer of the exclusive right are no bar to .an action to recover damages for an infringement committed before such sale and transfer.
The reason for the rule is, that the assignee or grantee is not interested in the damages'for any infringement committed before the sale and transfer of the patent. Correct interpretation of the words, person or persons interested, is, that the.words mean the person or persons interested in the 'patent at the time when the infringement was committed, which is the cause of action for which the damages may be recovered.
Assignment was made in that case after suit was brought, but before the final decree. Proof of the fact was offered, and a motion filed to dismiss the case, but the court over ruled the motion, because the assignees could have no interest in a suit for an infringement committed' before their right accruéd.
Attempt is made to distinguish the ease at bar from the rule established in those, cases, but, in the view of this court, without success.
Judgment reversed. New venire ordered.
