delivered the opinion of the court.
This appeal brings into review the decree dismissing, on a general demurrer, the amended bill of Hayward, the complainant, for want of equity.
The case made by the amended bill and exhibits is this: *673 Aaron H. Allen was the owner of reissued patent No. 1126, granted to him upon the surrender of original patent No. 12,017, dated Dec. 5, 1854, for a new and useful improvement in seats for public buildings. It was extended for seven years from Dec. 5, 1868, and consequently expired by limitation Dec. 4, 1875. By virtue of certain written instruments, set out as exhibits to the bill, the complainants claimed to be the sole and exclusive owner in equity of all claims for damages arising out of, or occasioned by, infringements of the reissued patent, committed after Sept. 18, 1869, and of all claims for gains and profits, derived by others by reason of such infringement.
The first of these instruments is dated Sept. 18,1869. Allen thereby grants to J. W. Schermerhorn & Co. “ the sole right and privilege of manufacturing and selling school furniture, made according to ” the reissued patent, “ for a tilting seat on the lever principle,” subject to the terms and conditions of an indenture between the parties, which, however, is not set out. On April 22,1881, John H. Platt, as assignee of James W. Schermerhorn, George M. Kendall, and George Munger, bankrupts, transfers to the complainant all the interest of the bankrupts in the Allen patent, and all causes of action arising to him, as assignee of the bankrupts, by reason of his interest in the said patent, and especially his claim in a certain suit then pending, brought by Allen in the Circuit Court of the' United States for the Southern District of New York against the city of New York.
The second and only other instrument of title exhibited is an assignment from Allen, the patentee, to the complainant, dated March 8, 1880, whereby Allen transfers to him and to. his assigns all his right and interest in the suit, mentioned in the assignment from Platt, against the city of New York, “ together with all claims for damages arising since the eighteenth day of September, 1869, against any. persons, firms, or corporations, by reason of infringements of letters-patent of the United States' for a tilting .seat supported on the lever principle,” being the reissued patent specified in the bill. And the complainant is thereby further constituted the attorney in fact of Allen, irrevocably, in his name, to demand and recover all such dam *674 ages, for his own use, paying all expenses, but accounting for thirty per cent of all sums recovered, to Allen, until- the latter shall have received $6,600, and no longer..
It is alleged in the amended bill that in the suit against the city of New York a decision was reached sustaining the validity of the patent, but no final decree therein has been entered; and that, owing to the delays incident to that litigation, while waiting for a decision upon the validity of the patent, neither Allen . nor the complainant has been in a situation to prosecute other infringers-, or sooner to file this bill.
It is also alleged in the,amended bill that the defendants-have infringed the said letters-patent since Sept. 18, 1869, and until the expiration thereof, and in violation thereof “ have manufactured, sold, and used the said invention for improve- ' ments in seats for public buildings, patented as aforesaid, whereby great injury resulted to your orator, and great gains and profits accrued to the said defendants,” for which, accordingly, an account is prayed, and a decree for the amount théreof and for damages.
The original bill was filed Dec. 1, 1881, Allen being a co-complainant, and the amended bill May 25, 1882, the original bill having been dismissed as to him.
It is manifest that the right claimed by the complainant receives no support from any title derived from Allen through J. W. Schermerhorn & Co., for' the right of the latter under the instrument of Sept. 18,1869, was that of mere licensees. They could maintain no action for damages or profits against infringers, for they had no interest in the patent, nor was there any assignment to them of any right of action accrued or to accrue to Allen. In addition to this, the license itself only extended to the manufacture and sale of school furniture, and there is no allegation in the amended bill that the defendants had infringed the patent in that respect. That branch, therefore, of the complainant’s bill is removed from the ease, and he is relieved from the embarrassment which, it is alleged in argument, is occasioned by the uncertainty produced by alternative and inconsistent titles, and which, is made one of the grounds for claiming.the right to resort to equity.
The case, then,, is left to stand upon the right derived under *675 the contract between Allen and the complainant of March 8, 1880, and the single question remains, whether the assignee of a chose in action may proceed by bill in equity to enforce for his own use the legal right of his assignor, merely because he cannot sue at law in his own name.
It is admitted that, according to the rule declared and established in
Root
v.
Railway
Company,
In opposition to this view, a passage from Story, Eq. Jur., .sect. 1057 a, is cited and relied on in argument, in which that learned author, after stating that it ha'd been “ recently held that the assignee of a debt, not in itself negotiable, is not entitled to sue the debtor for it in equity, unless some circumstances intervened which show that his remedy at law is, or may be, obstructed by the assignor,” adds, that “ this doctrine'is apparently new, at least, in the broad extent in which it is. laid down, and .does not' seem to have been generally adopted in America.. On the contrary, the more general principle established in this country seems to be, that wherever an assignee has an equitable right or interest in a debt or other property (as the assignee of a debt certainly h.as), then a court of equity is the proper forum to enforce it; and he is not to be driven to any circuity by instituting a suit at law in the name of the person who is possessed-of the legal title.” In the next paragraph, however,-it is admitted that, “ if the assignment be of a contract involving the consideration and ascertainment of unliquidated damages, as in case of the assignment of a policy of insurance, then, unless some obstruction exists to the remedy at law, it would seem that a court of equity ought not, or might not, interfere to grant relief; for the facts and the damages are properly matters for a jury to ascertain and decide. But the same objection would not lie to an assignment of a bond or other security for a fixed sum.”
The doctrine referred to in this passage, as “ apparently new,” is that stated by Vice-Chancellor Shadwell, in Hammond v. Messenger, 9 Sim. 327, 332, where he said: “If this case were stripped of all special circumstances, it would-be simply a bill filed by a plaintiff, who had obtained from Certain persons to whom a debt was due, a right to sue in. their name for the. debt. It is quite new to me, that, in such a simple case as that, this court allows, in the first instance, a bill to be filed against the debtor by the person who has become the. assignee of the debt. I admit that' if special circumstances are stated, and it is represented that notwithstanding the right which the party has obtained 'to sue in the name of the creditor, the creditor . *677 will interfere and prevent the exercise of that right, this court will interpose for the purpose of preventing that species of wrong being done; and if the creditor will not allow the matter to be tried at law in. his name, this court has a jurisdiction in the first instance to compel the debtor to pay the debt to the plaintiff, especially in a case where the act done by the creditor is done in collusion with the debtor. If bills of this' kind were allowable, it is obvious they would be pretty frequent; but I never remember any instance of such a bill as this being filed, unaccompanied by special circumstances.”
And, accordingly,.the Supreme Judicial Court of Massachusetts, in
Walker
v.
Brooks,
The same doctrine had received a pointed application by this court in the case of
Thompson
v.
Railroad Companies,
That decision has been cited with approval' in the subsequent cases of
Walker
v.
Dreville,
In the present case, the complainant had a plain and adequate remedy at law by an action in the name of Allen, whose willingness to permit ■ his name to be so used, in accordance with' his agreement to that effect, is manifest, from the fact that in the original bill he was named as one of the complain *679 ants. There was, therefore, no error committed- by the circuit court in dismissing the amended bill for want of jurisdiction in equity.
Decree affirmed.
