A. to whom had been assigned letters patent, filed, after the
expiration of them, which took place July 6, 1873, his bill against
B., charging that the latter had during their term infringed them
by using the patented invention, whereby he realized gains,
profits, and savings which he should be compelled to account for
and pay to the complainant. The bill was, on demurrer, dismissed.
Held that the decree below is proper, the bill being
merely for an account of profits and damages against an infringes,
and it not appearing from the case thereby made that any ground of
equitable jurisdiction exists, or that A. has not a complete remedy
at law whereby damages for the wrongs complained of can be
recovered.
The facts are stated in the opinion of the Court.
MR. JUSTICE MATTHEWS delivered the opinion of the Court.
Thomas Sayles, as assignee of the letters patent originally
granted to Henry Tanner for an improvement in railroad car brakes,
dated July 6, 1852, and which, on July 5, 1866, were renewed and
extended for the additional term of seven years, which expired July
6, 1873, filed his bill in the court below on Dec. 9, 1878, against
the Lake Shore and Michigan Southern Railway Company. He avers
that, by virtue of the assignments to him, he was invested with all
rights of action for infringements of the patent which had
occurred, and particularly
Page 105 U. S. 190
those of which it was alleged the defendant had been guilty from
Aug. 6, 1869, to July 6, 1873, having, as is averred, during that
period, used upon its railroad cars the patented brakes, but how
many, the bill states, the complainant is ignorant and cannot set
forth, but avers that the number so used was large, and that
defendant had derived, received, and realized great gains and
profits therefrom, but to what amount he is ignorant and cannot set
forth.
The prayer of the bill is that the defendant may be compelled to
account for and pay to the complainant all the gains, profits, and
savings which it derived, received, or realized from or by reason
of the use of said brakes.
To this bill a general demurrer was filed, alleging as grounds
thereof that the bill does not contain any matter of equity on
which the court could grant any relief and that the complainant is
not entitled to the relief prayed for because he had a plain,
adequate, and complete remedy at law and also because it appeared
on the face of the bill that the causes of complaint were barred by
the statutes of limitation both of the United States and of the
State of Illinois.
This demurrer was sustained and the bill dismissed. The decree
of the circuit court was brought here for review. Sayles having
died, Charles T. Root was, as his executor, substituted in this
Court as the appellant.
The propositions mainly relied upon by the appellee in support
of the decree, are:
First, that after the expiration of a patent, equity
has no jurisdiction to entertain a bill merely for an account and
the recovery of the profits of an infringer during its existence,
the remedy being at law for damages, and
Second, that even if in certain cases such a
jurisdiction exists, the present does not fall within it.
On the other hand, it is contended on the part of the appellant
that in cases for the enforcement of the rights of patentees,
resort may be had as matter of right to a court of equity, as a
distinct head of its jurisdiction, for the mere purpose of
establishing an infringement and ascertaining and recovering the
profits of the infringer upon the independent equity that he is for
that purpose a trustee of his gains for the
Page 105 U. S. 191
use of the true owner of the patent and liable to account as
such. In support of this contention, we are referred by his counsel
to numerous decisions of the circuit courts, many of which, it is
claimed, are directly upon the point, and to several cases in this
Court in which, it is alleged, the same doctrine is either
virtually decided or assumed, which, it is further argued, though
not supported by the modern decisions of the English chancery, is
found in its earlier precedents.
An examination of the practice and opinions of the circuit
courts undoubtedly shows much diversity, incapable of
reconciliation, and makes it necessary, as far as it can be done,
by a deliberate judgment of this Court, to remove the question out
of its present uncertainty by a settlement upon some basis of
principle in harmony with our system of equity jurisprudence
developed and modified by legislation. To effect this
satisfactorily and intelligently, it will be necessary to review
the course of legislation and judicial decision in this Court so
far as it bears upon the question from the beginning.
Prior to the passage of the Act of Feb. 15, 1819, c. 19, 3 Stat.
481, Congress had passed three laws in execution of the power
conferred by the Constitution itself and in furtherance of the
policy thereby indicated to secure to inventors an exclusive right
of property in their inventions. The first of them, the Act of
April 10, 1790, c. 7, 1 Stat. 109, gave as a remedy for its
violation an action at law upon the case for damages and forfeited
the infringing article. The next was the Act of Feb. 21, 1793, c.
11, 1 Stat. 318, which fixed the rule and measure of damages
recoverable in an action at law upon the act at three times the
price at which the patentee had usually sold or licensed to other
persons the use of the invention. This was changed by the Act of
April 17, 1800, c. 25, 2 Stat. 37, to three times the actual damage
sustained by the patentee by reason of the infringement. By neither
of these acts, however, was any jurisdiction conferred upon the
courts of the United States in equity. In
Livingston v. Van
Ingen, 1 Paine 45, Mr. Justice Livingston held that to vest
such jurisdiction by reason of the subject matter, as a case
arising under the laws of the United States, to be exercised in
controversies between parties without regard to their
citizenship,
Page 105 U. S. 192
it required the express authority of an act of Congress, and the
parties to that suit being citizens of New York, the bill was
dismissed. The controversy was thereupon renewed in the courts of
that state, and the Chancellor having refused the injunction asked
for, it was brought by appeal into the court for the correction of
errors. 9 Johns. (N.Y.) 507. It was there objected that the right
in question rested upon statute alone, which prescribed remedies at
law for its violation, which, it must be deemed, were intended to
be exclusive. But the decision affirmed the jurisdiction. "The
principle is," said Kent, C.J. (p. 587),
"that statute privileges, no less than common law rights, when
in actual possession and exercise, will not be permitted to be
disturbed until the opponent has fairly tried them at law and
overthrown their pretension."
The same learned judge refers also to the practice of the
federal courts in granting injunctions under the patent law,
mentioning two instances -- one the case of
Morse v. Reid,
an injunction bill filed in 1796 to restrain the invasion of a
copyright; the other
Whitney v. Fort, in which an
injunction was granted to restrain the violation of the patent for
the cotton gin. Of course, in those cases, the jurisdiction of the
court depended on the citizenship of the parties.
Congress then passed the Act of Feb. 15, 1819, c. 19, which
enacted
"That the circuit courts of the United States shall have
original cognizance, as well in equity as at law, of all actions,
suits, controversies, and cases arising under any law of the United
States, granting or confirming to authors or inventors the
exclusive right to their respective writings, inventions, and
discoveries, and upon any bill in equity, filed by any party
aggrieved in any such cases, shall have authority to grant
injunctions, according to the course and principles of courts of
equity, to prevent the violation of the rights of any authors or
inventors secured to them by any law of the United States, on such
terms and conditions as the said courts may deem fit and
reasonable."
In the case of
Sullivan v. Redfield, 1 Paine 441, which
was decided in 1825, Mr. Justice Thompson, who in the
Livingston case had sat as one of the judges of the state
court, had occasion to consider the nature of the equity
jurisdiction in patent
Page 105 U. S. 193
suits. "The equity jurisdiction," he said,
"exercised by the court over patents for inventions is merely in
aid of the common law, and in order to give more complete effect to
the provisions of the statute under which the patent is
granted."
And in answer to the argument that the act of 1819 gave a
peremptory right to an equitable remedy by virtue of the patent
itself, he said:
"This act does not enlarge or alter the powers of the court over
the subject matter of the bill or the cause of action. It only
extends its jurisdiction to parties not before falling within it.
Before this act, it had been held that a citizen of one state could
not obtain an injunction in the circuit court for a violation of a
patent right against a citizen of the same state, as no act of
Congress authorized such suit. This act removed that objection and
gave the jurisdiction, although the parties were citizens of the
same state. But in the exercise of the jurisdiction in all cases of
granting injunctions to prevent the violation of patent rights, the
court is to proceed according to the course and principles of
courts of equity in such cases. So that the questions presented in
the present case are precisely where they would have been without
this act."
The substance of the act of 1819 was incorporated into the
seventeenth section of the Act of July 4, 1836, c. 357, 5 Stat.
117, so far as it related to inventors, but remained in force,
after the passage of the latter act so far as it gave cognizance to
the courts of the United States of cases of copyright. It was under
that provision of the act of 1819 that the case of
Stevens v.
Gladding arose and was decided. 17 How. 447. That
was a bill for an injunction to restrain the violation of a
copyright, and prayed for the recovery of the penalties given by
the seventh section of the Act of Feb. 3, 1831, c. 16, and for
general relief. Mr. Justice Curtis, delivering the opinion of the
Court, said:
"There is nothing in this act of 1819 which extends the equity
powers of the courts to the adjudication of forfeitures, it being
manifestly intended that the jurisdiction therein conferred should
be the usual and known jurisdiction exercised by courts of equity
for the protection of analogous rights. The prayer of this bill for
the penalties must therefore be rejected. The remaining question is
whether there ought to be a decree for an account of the profits.
The complainant
Page 105 U. S. 194
has not prayed for such an account, nor have the defendants
stated one in their answer, but the bill does pray for general
relief. The right to an account of profits is incident to the right
to an injunction in copy and patent right cases,"
citing
Colburn v. Simms, 2 Hare 554; 3 Dan.Ch.Pr.
1797.
"And this Court has held, in
Watts v.
Waddle, 6 Pet. 389, that where the bill states a
case proper for an account, one may be ordered under the prayer for
general relief."
The seventeenth section of the act of 1836 differs from the act
of 1819 in one other particular only. It makes the jurisdiction in
patent causes of the court of the United States exclusive.
It was under the act of 1836 that the question arose for the
first time in
Livingston v.
Woodworth, 15 How. 546, as to the rule for
computing the profits of an infringer upon a decree for such an
account. The bill was for an injunction and account. The validity
of the patent and the fact of infringement were both admitted by
the defendant, who consented to a decree requiring him to account
for and pay over the gains and profits made by him during the
infringement in accordance with the prayer of the bill. The decree
confirmed the report of the master, who awarded not actual gains
and profits, but such as he estimated the defendant might have made
by due diligence. It was argued in support of the decree that where
the court has jurisdiction to give the principal relief sought, it
will make a complete decree, and give compensation for the past
injury, as in bills for specific performance and injunction bills
for waste, and that it was a correct rule to hold the party
accountable, as an involuntary trustee, for what the patentee might
have realized by the same exercise of the right, as a court of
equity sometimes forces the character of a trustee upon an intruder
or wrongdoer or one in possession under color of right or who takes
rents or profits belonging to another or might have taken them, as
in cases of mortgagees; but it was admitted that the case was of
first impression. The decree upon this point was reversed. The
Court said:
"We are aware of no rule which converts a court of equity into
an instrument for the punishment of simple torts. . . . If the
appellees, the plaintiffs below, had sustained
Page 105 U. S. 195
an injury to their legal rights, the courts of law were open to
them for redress, and in these courts they might, according to a
practice which, however doubtful in point of essential right, is
now too inveterate to be called in question, have claimed not
compensation merely, but vengeance for such injury as they could
show they have sustained. But before a tribunal which refuses to
listen even to any save those whose acts and motives are perfectly
fair and liberal, they cannot be permitted to contravene the
highest and most benignant principle of the being and constitution
of that tribunal. There they will be allowed to claim that which,
ex aequo et bono, is theirs, and nothing beyond this."
P.
56 U. S. 559.
The account was therefore restricted to the actual gains and
profits of the appellants during the time their machine was in
operation.
This rule in relation to the profits recoverable in such suits
was followed in
Dean v. Mason,
20 How. 198, which was a case of a bill for an injunction and
account in which a decree
pro confesso had been taken. The
final decree was entered on the report of the master for the
estimated amount of profits which the defendant with reasonable
diligence might have realized, not what in fact he did realize.
This was held to be erroneous. The Court said:
"The rule in such a case is the amount of profits received by
the unlawful use of the machines, as this, in general, is the
damage done to the owner of the patent. It takes away the motive of
the infringer of patented rights by requiring him to pay the
profits of his labor to the owner of the patent. Generally this is
sufficient to protect the rights of the owner, but where the wrong
has been done under aggravated circumstances, the court has the
power under the statute to punish it adequately by an increase of
the damages."
The important case of
Seymour v.
McCormick, 16 How. 480, was decided in 1853. That
was an action at law. The court below instructed the jury that the
actual damages to which the plaintiff was entitled for an
infringement of a patent for an improvement in a machine might be
determined by ascertaining the profits which in judgment of law he
would have made provided the defendants had not interfered with his
rights, and that the same rule applied whether the patent covered
an entire machine or merely an improvement on a
Page 105 U. S. 196
machine. This instruction this Court held to be erroneous, and
reversed the judgment on that account. Mr. Justice Grier, in
delivering the opinion of the Court, referred to the rule of
damages, prescribed by the acts of Congress previously in force,
stating that "experience had shown the very great injustice of a
horizontal rule equally affecting all cases without regard to their
peculiar merits," and that it was to obviate this that the Patent
Act of 1836 confined the jury to the assessment of actual damages,
leaving it to the discretion of the court to inflict punitive
damages to the extent of trebling the verdict. He then
remarked:
"It must be apparent to the most superficial observer of the
immense variety of patents issued every day that there cannot, in
the nature of things, be any one rule of damages which will equally
apply to all cases. The mode of ascertaining actual damages must
necessarily depend on the peculiar nature of the monopoly granted.
A man who invents or discovers a new composition of matter, such as
vulcanized India rubber or a valuable medicine, may find his profit
to consist in a close monopoly forbidding anyone to compete with
him in the market, the patentee being himself able to supply the
whole demand at his own price, in which cases 'the profit of the
infringer may be the only criterion of the actual damage of the
patentee;' that"
"one who invents some improvement in the machinery of a mill
could not claim that the profits of the whole mill should be the
measure of damages for the use of his improvement, and where the
profit of the patentee consisted neither in the exclusive use of
the thing invented or discovered nor in the monopoly of making it
for others to use, it is evident that this rule could not apply.
The case of Stimpson's patent for a turnout in a railroad may be
cited as an example. It was the interest of the patentee that all
railroads should use his invention, provided they paid him the
price of his license. He could not make his profit by selling it as
a complete and separate machine. An infringer of such a patent
could not be liable to damages to the amount of the profits of his
railroad, nor could the actual damages of the patentee be measured
by any known ratio of the profits of the road. . . . It is only
where, from the peculiar circumstances of the case, no other rule
can be found that the defendant's
Page 105 U. S. 197
profits become the criterion of the plaintiff's loss. Actual
damages must be actually proved, and cannot be assumed as a legal
inference from any facts which amount not to actual proof of the
fact."
Accordingly, it was held in
Corporation of New York v.
Ransom, 23 How. 487, where the rule in
Seymour
v. McCormick, supra, was expressly approved, that in an action
at law, if the plaintiff rested his case after proof of
infringement merely, he was entitled only to nominal damages. It
was also applied in
Jones v.
Morehead, 1 Wall. 155, which was a bill in equity
for an injunction and an account, where a decree for a large sum as
profits had been rendered against the defendant, upon an entire
machine, in respect to which it appeared as matter of fact that the
defendants had not infringed the patent sued on, but had admitted
to the contrary in the answer. The Court construed this admission
by applying it to the smallest number of patented articles, and to
the use of any part of the patent found to be valid, and, reversing
the decree, ordered one to be entered for a "nominal sum of one
dollar for profits."
In
Rubber Company v.
Goodyear, 9 Wall. 788, which was a bill for an
injunction and account, a decree for a large sum was rendered in
favor of the complainants, which was affirmed on appeal. "The
rule," said Mr. Justice Swayne, delivering the opinion of the
Court,
"is founded in reason and justice. It compensates one party and
punishes the other. It makes the wrongdoer liable for actual, not
possible, gains. The controlling consideration is that he shall not
profit by his wrong. A more favorable rule would offer a premium to
dishonesty and invite to aggression. The jurisdiction of equity is
adequate to give the proper remedy, whatever phase the case may
assume, and the severity of the decree may be increased or
mitigated according to the complexion of the conduct of the
offender."
Mowry v.
Whitney, 14 Wall. 620, was also a bill in equity
for an injunction and account. A decree was rendered in favor of
the complainant for all the profits on the manufactured article,
instead of upon the patented process of manufacture, with interest
added. On appeal, this Court reversed the decree on that point,
saying:
"The question to be determined
Page 105 U. S. 198
in this case is what advantage did the defendant derive from
using the complainant's invention over what he had in using other
processes then open to the public and adequate to enable him to
obtain an equally beneficial result. The fruits of that advantage
are his profits. . . . That advantage is the measure of
profits."
On the question of interest, Mr. Justice Strong, speaking for
the Court, said:
"We add only that in our opinion, the defendant should not have
been charged with interest before the final decree. The profits
which are recoverable against an infringer of a patent are in fact
a compensation for the injury the patentee has sustained from the
invasion of his right. They are the measure of his damages. Though
called profits, they are really damages, and unliquidated until the
decree is made. Interest is not generally allowable upon
unliquidated damages. We will not say that in no possible case can
interest be allowed. It is enough that the case in hand does not
justify such an allowance."
In
Packet Company v.
Sickles, 19 Wall. 611, which was an action at law,
the rule established in
Seymour v. McCormick, supra, was
reiterated, as "the established criterion of damages in cases to
which it was applicable."
"In cases where there is no established patent or license fee in
the case, or even an approximation to it, general evidence must
necessarily be resorted to,"
as was said by the Court in the case of
Suffolk
Co. v. Hayden, 3 Wall. 315. "And what evidence,"
said Mr. Justice Nelson, in that case, p.
70 U. S. 320,
"could be more appropriate and pertinent than that of the
utility and advantage of the invention over the old modes or
devices that had been used for working out similar results? With a
knowledge of these benefits to the persons who have used the
invention, and the extent of the use by the infringer, a jury will
be in possession of material and controlling facts that may enable
them, in the exercise of a sound judgment, to ascertain the
damages, or, in other words, the loss to the patentee or owner by
the piracy instead of the purchase of the use of the
invention."
He added that
"a recovery does not vest the infringer with the right to
continue the use, as the consequence of it may be an injunction
restraining the defendant from the further use of it. "
Page 105 U. S. 199
In
Packet Company v. Stickles, supra, MR. JUSTICE
MILLER said:
"The rule in suits in equity, of ascertaining by a reference to
a master the profits which the defendant has made by the use of the
plaintiff's invention, stands on a different principle. It is that
of converting the infringer into a trustee for the patentee as
regards the profits thus made, and the adjustment of these profits
is subject to all the equitable considerations which are necessary
to do complete justice between the parties, many of which would be
inappropriate in a trial by jury. With these corrective powers in
the hands of the chancellor, the rule of assuming profits as the
groundwork for estimating the compensation due from the infringer
to the patentee has produced results calculated to suggest distrust
of its universal application even in courts of equity."
The doctrine of this case was reiterated in
Burdell v.
Denig, 92 U. S. 716, where
MR. JUSTICE MILLER, again delivering the opinion of the Court,
said:
"Profits are not the primary or true criterion of damages for
infringement in an action at law. That rule applies eminently and
mainly to cases in equity, and is based on the idea that the
infringer shall be converted into a trustee, as to those profits
for the owner of the patent which he infringes, a principle which
it is very difficult to apply in a trial before a jury, but quite
appropriate on a reference to a master, who can examine defendant's
books and papers, and examine him on oath, as well as all his
clerks and employees. On the other hand, we have repeatedly held
that sales of licenses of machines, or of a royalty established,
constitute the primary and true criterion of damages in the action
at law. No doubt, in the absence of satisfactory evidence of either
class in the forum to which it is most appropriate, the other may
be resorted to as one of the elements on which the damages or the
compensation may be ascertained."
Littlefield v.
Perry, 21 Wall. 205, was one where the patentee, by
force of an agreement, held the legal title to the patent in trust
for the complainant, in violation of which he was making use of his
legal rights. It was held, upon a bill filed for an injunction and
account, that it was a case under the patent laws, and the
defendant was required to account for the
Page 105 U. S. 200
profits he had made, according to the rule in
Mowry v.
Whitney, supra. The Chief Justice said, p.
88 U. S. 230:
"Profits actually realized are usually, in a case like this, the
measure of unliquidated damages. Circumstances may, however, arise
which would justify the addition of interest in order to give
complete indemnity for losses sustained by willful
infringements."
By the Act of July 8, 1870, c. 230, Congress revised,
consolidated, and amended the statutes relating to patents and
copyrights. 16 Stat. 198. The fifty-ninth section renewed the
provision previously in force that damages for infringement might
be recovered by action on the case, and that whenever in any such
action a verdict shall be rendered for the plaintiff, the court may
enter judgment therein for any sum above the amount found by the
verdict as the actual damages sustained, according to the
circumstances of the case, not exceeding three times the amount of
the verdict. The fifty-fifth section is as follows:
"That all actions, suits, controversies, and cases arising under
the patent laws of the United States shall be originally
cognizable, as well in equity as at law, by the circuit courts of
the United States or any district court having the power and
jurisdiction of a circuit court, or by the Supreme Court of the
District of Columbia, or of any territory, and the court shall have
power, upon bill in equity filed by any party aggrieved, to grant
injunctions according to the course and principles of courts of
equity to prevent the violation of any right secured by patent on
such terms as the court may deem reasonable, and upon a decree's
being rendered in any such case for an infringement, the
complainant shall be entitled to recover, in addition to the
profits to be accounted for by the defendant, the damages the
complainant has sustained thereby, and the court shall assess the
same or cause the same to be assessed under its direction, and the
court shall have the same powers to increase the same in its
discretion that are given by this act to increase the damages found
by verdicts in actions upon the case; but all actions shall be
brought during the term for which the letters patent shall be
granted or extended or within six years after the expiration
thereof."
These provisions are substantially carried into the Revised
Statutes, sec. 59 of the act of 1870, being sec. 4919 of the
Page 105 U. S. 201
latter, and sec. 55 corresponding to sec. 4921 Rev.Stat., except
as to the provision in respect to the limitation upon the right to
sue, which is not found in the Revised Statutes. But the rights of
the parties in the present suit arose while the act of 1870 was in
force, and are determinable under it.
In the case of
Birdsall v. Coolidge, 93 U. S.
64, it is declared, in reference to the effect of the
act of 1870, that
"gains and profits are still the proper measure of damages in
equity suits, except in cases where the injury sustained by the
infringement is plainly greater than the aggregate of what was made
by the respondent,"
in which event the provision is that the complainant "shall be
entitled to recover, in addition to the profits to be accounted for
by the respondent, the damages he has sustained thereby."
Mr. Justice Clifford, in the opinion in this case, quotes a
passage, slightly altered, from Curtis on Patents, sec.
341
a (4th ed.), p. 461, which, taken by itself, might seem
to imply that prior to the act of 1870, the owner of a patent had
the election to resort to a court of equity for the recovery of
profits, or a court of law for damages, irrespective of any other
relief of an equitable character; but the language of the passage
is to be restrained to mean merely that the option existed to sue
at law for past infringement, or seek equitable relief by way of
prevention, the damages or profits following, as either
jurisdiction is resorted to, each according to its kind. For if
this be not so, it follows that since the passage of the act of
1870, an owner of a patent may recover, in a suit in equity,
profits and damages in all cases, according to the rule above
stated, without seeking any other relief whatever, the effect of
which would be to give two remedies, one in equity, the other at
law, merely for the recovery of damages for an injury to a legal
right, an anomaly not to be found in any other branch of our
jurisprudence. And manifestly, upon such a construction, the action
at law would soon become obsolete as completely as if it had been
abolished by legislation. The whole force of the change in the
statute consists in conferring upon courts of equity, in the
exercise of their jurisdiction in administering the relief, which
they are accustomed and authorized to give, and which is
appropriate to their forms of procedure, the power
Page 105 U. S. 202
not merely to give that measure of compensation for the past,
which consists in the profits of the infringer, but to supplement
it, when necessary, with the full amount of damage suffered by the
complainant, and which, if he had sued for that alone, he would
have recovered in another forum, with power to increase the amount
of the actual damages, as in courts of law. But as the account of
profits previously was the incident of the suit, and not its
object, so now the power to award damages and to multiply them is
added as an incident to the right to an account.
But the difference between the state of the law before and after
the act of 1870 finds its best illustration in a comparison between
two cases, both of which were decided at the October Term, 1877,
Elizabeth v. Pavement Company, 97 U. S.
126, and
Marsh v. Seymour, 97 U. S.
348.
In the former, the bill was filed before the passage of the act,
but prayed, besides an injunction, for both damages and profits. It
was held that the court below had rightly decided that a decree for
profits alone could be rendered, inasmuch as the jurisdiction of
courts of equity to decree damages, as distinct from profits, was
first conferred by the statute. MR. JUSTICE BRADLEY, delivering the
opinion of the Court, remarking that the general question of the
profits recoverable in equity by a patentee was surrounded with
many difficulties which the courts had not yet succeeded in
overcoming, said:
"But one thing may be affirmed with reasonable confidence, that
if an infringer of a patent has realized no profit from the use of
the invention, he cannot be called upon to respond for profits; the
patentee in such case is left to his remedy for damages. It is also
clear that a patentee is entitled to recover the profits that have
been actually realized from the use of his invention, although from
other causes the general business of the defendant, in which the
invention is employed, may not have resulted in profits -- as when
it is shown that the use of his invention produced a definite
saving in the process of a manufacture.
Mowry v.
Whitney, 14 Wall. 434;
Cawood Patent,
94 U. S.
695. On the contrary, though the defendant's general
business be ever so profitable, if the use of the invention has not
contributed to the profits, none can be recovered. The
Page 105 U. S. 203
same result would seem to follow where it is impossible to show
the profitable effect of using the invention upon the business
results of the party infringing. It may be added that where no
profits are shown to have accrued, a court of equity cannot give a
decree for profits by way of damages or as a punishment for the
infringement.
Livingston v. Woodworth,
15 How. 559. But when the entire profit of a business or
undertaking results from the use of the invention, the patentee
will be entitled to recover the entire profits if he elects that
remedy. And in such a case, the defendant will not be allowed to
diminish the show of profits by putting in unconscionable claims
for personal services or other inequitable deductions.
Rubber
Company v. Goodyear, 9 Wall. 788."
And these general propositions, he added, will hardly admit of
dispute.
Accordingly, in that case, the bill was dismissed as to the City
of Elizabeth, which had infringed, because it appeared that it had
made no profit from the use of the patented improvement, while a
decree was rendered against the contractor, who had laid the
pavement which was the subject of the patent, because he was shown
to have made profits from the infringement. The municipal
corporation, of course, remained liable to respond in damages in an
action at law for any loss which the plaintiff could have
established by proof.
The cases of
Marsh v. Seymour, supra, arose under the
act of 1870, and were bills for injunction and account. Decrees
were rendered in favor of the complainant, and a reference ordered
to a master to state an account of profits. In both cases, the
respondents showing that they had made no profits by reason of the
use of the invention, the complainant waived his claim for a
recovery on that account, and decrees were rendered for damages on
the basis of a license fee for the infringing machines which had
been sold, and nominal damages for those manufactured but not sold.
These decrees were affirmed, the Court saying, Mr. Justice Clifford
delivering its opinion, that
"damages of a compensatory character may be allowed to a
complainant in an equity suit where it appears that the business of
the infringer was so improvidently conducted that it did not yield
any substantial profits, as in the case before the Court. "
Page 105 U. S. 204
In
Parks v. Booth, 102 U. S. 96, which
was a suit in equity for an injunction, an account of profits, and
damages under the act of 1870, a decree was rendered in favor of
the complainant and for profits and damages as found by a master.
Under the head of damages there were included items for expenses of
conducting the suit, being counsel fees, compensation for the
complainant's time, and interest on the profits. The decree was
modified on appeal by striking out all these allowances except that
for the complainant's time lost in attending to the suit. Interest
on profits was, on the authority of
Silsby v.
Foote, 20 How. 378, disallowed on the ground that
profits in such a case are to be regarded in the light of
unliquidated damages. No injunction was decreed, as the term of the
patent had expired. It does not appear from the report of the case
when the suit was begun, but a reference to the original record
shows that the bill was filled in April, 1871, before the
expiration of the term of the patent.
Hendrie v. Sayles, 98 U. S. 546, was a
bill in equity for an account of profits, filed after the
expiration of the patent, the same patent on which the present suit
is founded. It was decided upon a single point raised on demurrer
to the bill, the question of jurisdiction not being noticed either
by counsel or court. A decree for the complainant was affirmed on
appeal.
This appears to be the only case of the kind, until the present,
that found its was into this Court.
Eureka Co. v. Bailey
Company, 11 Wall. 488, is no exception to this
remark, although in respect to it the observation has been made
that the injunction prayed for in that case was incidental to the
account, and not
vice versa. That, however, is a
misconception, for unless upon the ground of a difference of
citizenship, the Court would not have had jurisdiction to entertain
the bill in that case if it had not prayed for an injunction. For
the mere purpose of enforcing the contract for the royalty, it was
not a case arising under the patent laws so as to give jurisdiction
to the courts of the United States. It was because the defendant
was guilty of an infringement of the complainant's patent that he
was suable in equity in these courts, and to restrain that an
injunction was asked until he should pay what he had promised. The
object of the
Page 105 U. S. 205
suit doubtless was to collect the royalty; but it was sought by
means of, and therefore as an incident to, the jurisdiction of the
court, invoked for the purpose of enjoining the continuance of
what, until the royalty was acknowledged and paid, was found to be
an infringement.
All the acts of Congress relating to patents prior to that of
1870 contained provisions specifying the special defenses which
might be made in an action at law for an infringement, under the
plea of the general issue, notice thereof having been previously
given. The sixty-first section of the act of 1870 enumerates the
several special matters thus authorized to be proved, and adds, for
the first time in the history of this legislation, the clause
that
"The like defenses may be pleaded in any suit in equity for
relief against an alleged infringement, and proofs of the same may
be given upon like notice in the answer of the defendant and with
the like effect."
The plain and obvious purpose of this provision is to furnish
appropriate modes in equity pleading for the trial of all issues,
both of fact and law, relating both to the alleged infringement and
the validity of the patent, without the necessity of framing
special issues out of chancery for trial by jury or sending the
parties to a court of law for the trial of an action in that forum
in order to determine their legal right. It proceeds upon the idea
that the court of equity, having acquired jurisdiction for the
purpose of administering the equitable relief sought by the bill,
may determine directly and for itself, in the same proceeding, all
questions incidental to the exercise of its jurisdiction
notwithstanding they may be questions affecting legal rights and
legal titles.
Although this was the first statutory authority for the
practice, it was rather a recognition of what had already been
established than its introduction, for the practice had in fact
originated long before, and was based upon well known principles of
equity jurisprudence. Whatever question may have existed in
reference to it previously was settled in the courts of the United
States by
Goodyear v. Day, 2 Wall.Jr. 283, a case argued
by Webster and Choate and decided by Mr. Justice Grier in 1852.
That learned judge on that occasion said:
"It is true that in England, the Chancellor will generally not
grant a
Page 105 U. S. 206
final and perpetual injunction in patent cases, when the answer
denies the validity of the patent, without sending the parties to
law to have that question decided. But even there, the rule is not
absolute or universal; it is a practice founded more on convenience
than necessity. It always rests on the sound discretion of the
court. A trial at law is ordered by a chancellor to inform his
conscience, not because either party may demand it as a right or
that a court of equity is incompetent to judge of questions of fact
or of legal titles."
See also Orr v. Merrill, 1 Woodb. & M. 376.
The distinction in the nature of the two proceedings, of an
action at law and a suit in equity, is plainly pointed out in this
section of the statute, the former as being an action for an
infringement, the latter as a suit for relief against an alleged
infringement. And while, upon the words used in the fifty-fifth
section of the act, it may be that the jurisdiction in equity which
is thereby conferred is not exhausted by the power to grant
injunctions according to the course and principles of courts of
equity to prevent the violation of any right secured by patent, yet
the statute immediately says that it is upon a decree being
rendered in any
such case for an infringement -- as though
that was the only one -- that the complainant shall be entitled to
recover, in addition to the profits to be accounted for by the
defendant, the damages the complainant has sustained thereby.
It is impossible, we think to maintain the claim that the
language of this act, similar in that respect to the previous acts
of 1819 and 1836, conferring jurisdiction in patent cases in equity
as well as at law, was meant to obliterate the distinctions between
these two jurisdictions or even to confuse the boundaries between
them, as it is alleged was done by the decision in the case of
Nevins v. Johnson, 3 Blatch. 80, and perhaps in other
subsequent circuit court decisions. Indeed, it is the settled
doctrine of this Court that this distinction of jurisdiction,
between law and equity, is constitutional to the extent to which
the Seventh Amendment forbids any infringement of the right of
trial by jury as fixed by the common law. And the doctrine applies
in patent cases as well as others. This Court said in
Parsons v.
Bedford, 3 Pet. 433, speaking
Page 105 U. S. 207
of the meaning intended by the framers of that amendment,
that
"by common law, they meant what the Constitution denominated in
the 3d article, LAW, not merely
suits which the common law
recognized among its old and settled proceedings, but suits in
which
legal rights were to be ascertained and determined,
in contradistinction to those where
equitable rights alone
were recognized and equitable remedies administered."
The rule was repeated in
Fenn v. Holme,
21 How. 481, in this language:
"In every instance in which this Court has expounded the
phrases, proceedings at the common law and proceedings in equity,
with reference to the exercise of the judicial powers of the courts
of the United States, they will be found to have interpreted the
former as signifying the application of the definitions and
principles and rules of the common law to rights and obligations
essentially legal, and the latter as meaning the administration
with reference to equitable as contradistinguished from legal
rights, of the equity law as defined and enforced by the Court of
Chancery in England."
It becomes necessary, therefore, to consider what support there
is in the general doctrines of equity for the contention of the
appellant.
It is the fundamental characteristic and limit of the
jurisdiction in equity that it cannot give relief when there is a
plain and adequate and complete remedy at law, and hence it had no
original, independent, and inherent power to afford redress for
breaches of contract or torts by awarding damages, for to do that
was the very office of proceedings at law. When, however, relief
was sought which equity alone could give, as by way of injunction
to prevent a continuance of the wrong in order to avoid
multiplicity of suits and to do complete justice, the court assumed
jurisdiction to award compensation for the past injury -- not,
however, by assessing damages, which was the peculiar office of a
jury, but requiring an account of profits, on the ground that if
any had been made, it was equitable to require the wrongdoer to
refund them, as it would be inequitable that he should make a
profit out of his own wrong. As was said by Vice-Chancellor Wigram
in
Colburn v. Simms, 2 Hare 543,
"The court does not by an account accurately measure the damage
sustained by the proprietor
Page 105 U. S. 208
of an expensive work from the invasion of his copyright by the
publication of a cheaper book,"
but,
"as the nearest approximation which it can make to justice,
takes from the wrongdoer all the profits he has made by his piracy
and gives them to the party who has been wronged."
Whether a bill for an account of profits against a wrongdoer
would lie, independently of other equitable grounds for the
intervention of the court, is a question, as was said by Lord
Chancellor Brougham in
Parrott v. Palmer, 3 Myl. & K.
632,
"which has been oftentimes agitated and has perhaps never
received a clear and a general decision -- that is to say, a
distinct judgment on the general proposition, with its
limitations."
He concluded that,
"From the whole it may be collected that, although as to timber
there exists considerable discrepancy, yet the sound rule is to
make the account the incident and not the principal where there is
a remedy at law, but that mines are to be otherwise considered, and
that as to them, the party may have an account even in cases where
no injunction would lie."
The supposed exception in cases of mines seems to rest upon a
dictum of Lord Hardwicke in
Jesus College v.
Bloom, 3 Atk. 262, that "it was a sort of trade," but the
reference is to the case of
Bishop of Winchester v.
Knight, 1 P.W. 406, where the bill prayed for an account of
ore dug by the ancestor of the defendant, in respect to which the
argument was that being a personal tort, it died with the person.
The decision was that the plaintiff was not entitled, but on this
point the Lord Chancellor said:
"It would be a reproach to equity to say, where a man has taken
my property, as my ore or timber, and disposed of it in his
lifetime and dies, that in this case I would be without remedy. It
is true as to the trespass of breaking up meadow or ancient pasture
ground, it dies with the person; but as to the property of the ore
or timber, it would be clear even at law, if it came to the
executor's hands, that trover would lie for it, and if it has been
disposed of in the testator's lifetime, the executor, if assets are
left, ought to answer it."
It is plain from these observations that the assumed ground of
the equity jurisdiction was the absence of any remedy at law.
Powell v. Aiken, 4 Kay & J. 343. It is now
Page 105 U. S. 209
clearly established in the English chancery
"that a bill will not lie for an account of timber felled any
more than for any other money demand except when the account is
asked as an incident to an injunction, and that when the plaintiff
has no right to an injunction, he has no right to an account, and
his remedy is at law alone."
Per Sir Wm. M. James, L.J. in
Higginbotham v. Hawkins,
Law Rep. 7 Ch.App. 676.
The same rule is applied by the modern decisions in cases of
mines, where, as incident to the relief sought by a bill, an
account is asked of profits against trespassers. It appears that as
to the mode of assessing compensation in such suits to an owner of
coal which has been improperly worked by the owner of an adjoining
mine, a different principle is applicable when the coal is taken
inadvertently, or under a
bona fide belief of title, and
when it is taken fraudulently, with knowledge of the wrong. In
cases of the latter description at law, the strict rule of damages
laid down in
Martin v. Porter, 5 Mee. & W. 351, was to
charge the value of the coal without allowing any of the expenses
of getting it, but in those of the former description, a milder
rule was applied in
Morgan v. Powell, 3 Q.B. 278, and
Wood v. Morewood, id., 440, which was to give to the
plaintiff the fair value of the coals as if the coal field had been
purchased from him by the defendant. This distinction was adopted
and the latter rule applied in equity, by Vice-Chancellor Malins in
Hilton v. Woods, Law Rep. 4 Eq. 432, and by Lord
Chancellor Hatherley in
Jehon v. Vivian, Law Rep. 6
Ch.App. 742, the latter remarking that "this court never allows a
man to make profit by a wrong." This rule was adopted in
Stockbridge Iron Co. v. Cone Iron Works, 102 Mass. 80.
The same rule applies in England in patent and copyright cases.
The Vice-Chancellor Page-Wood, in
Smith v. London &
Southwestern Railway Co., Kay 408, said:
"The true ground of relief in these cases is laid down in
Baily v. Taylor, 1 Russ. & M. 73, where Sir J. Leach,
M.R., says:"
" The court has no jurisdiction to give to a plaintiff a remedy
for an alleged piracy unless he can make out that he is entitled to
the equitable interposition of this court by injunction, and in
such case the court will also give him an account, that his
Page 105 U. S. 210
remedy here may be complete. If this court do not interfere by
injunction, then his remedy, as in the case of any other injury to
his property, must be at law."
"Unless that primary right to an injunction exists, this court
has no jurisdiction with reference to a mere question of
damages."
The Vice-Chancellor further observed that, as had often been
stated by Lord Eldon, as the object of the court in interfering by
injunction was the prevention of a multiplicity of suits which
might be rendered necessary by continued infringements of the
patent, he was at a loss to see how the jurisdiction could attach
or the relief by injunction be arrived at, after the expiration of
the patent, unless a case were made out, of a numerous series of
past infringements, from which the parties were still deriving
advantage. He then referred to
Crossley v. Beverly, Web.
P.C. 119, as a case where there was a specific ground for that
relief, that the defendants had been manufacturing the patented
articles, secretly and fraudulently, for the purpose of pouring
into the market the articles so manufactured directly the patent
should have expired. In that case, the bill was filed before the
expiration of the patent, and the right to sue having been thus
acquired, the court extended it to restrain using the articles so
manufactured after the patent had expired. "Such a case," continues
the Vice-Chancellor,
"of a fraudulent attempt to evade the patent might occur as
would enable the court to restrain the use of articles made in
infringement of the patent and kept back until it expired, even
after its expiration, and the plaintiff having thus obtained a
right to the injunction, the right to an account would follow."
In the case of
Price's Pat. Candle Co. v. Bauwen's Pat.
Candle Co., 4 Kay & J. 727, the bill was dismissed
because, the patent having expired
pendente lite, the
relief by injunction could not be granted at the hearing; but in
Davenport v. Rylands, Law Rep. 1 Eq. 302, the same judge
retained the bill under similar circumstances for the purposes of
an inquiry as to damages, because the act of 21 & 22 Vict., c.
27, commonly called Cairn's Act, passed after the former decision,
had altered the rule. That statute declared that in all cases in
which the court has jurisdiction to entertain an application for an
injunction against a breach of any covenant, contract, or
agreement,
Page 105 U. S. 211
or against the commission or continuance of any wrongful act, or
for the specific performance of any covenant, contract, or
agreement, the same court may award damages to the party injured
either in addition to or in substitution for such injunction or
specific performance, and such damages may be assessed in such
manner as the court shall direct -- a provision which no doubt
suggested the like extension of the jurisdiction of the court in
patent cases, contained in our Patent Act of 1870. But even after
the passage of Cairn's Act, it was decided by Vice-Chancellor Sir
Wm. M. James, in
Betts v. Gallais, Law Rep. 10 Eq. 392,
that the court would not entertain a bill for the mere purposes of
giving relief in damages for the infringement of a patent when the
bill had been filed so immediately before the expiration of the
patent as to render it impossible to have obtained an interlocutory
injunction. He characterized it as "a mere device to transfer a
plain jurisdiction to award damages from the court to which that
jurisdiction properly belongs, to this Court."
Mr. Kerr, in his treatise on Injunctions 41, summarizes the
result of many decisions, which he cites, under this statute, as
follows:
"The statute did not transfer to the court the general
jurisdiction of common law by way of damages, or extend its
jurisdiction to cases where previously to the statute it had no
jurisdiction, or could not, consistently with its rules and
principles, have interfered. The statute merely empowered the court
to give damages in cases involving elements or ingredients of an
equitable character. If the case as presented to the court was an
equitable one, so that the subject matter of the application is
properly cognizable in equity, the court had jurisdiction under the
statute to entertain the question of damages. If, on the other
hand, the plaintiff had no equitable right at the time of bringing
the action, so that the matter has been improperly brought into
equity, the statute had no application. Damages may be awarded
under the statute if it appear that at the time of bringing the
action there was an equitable case, although the case for an
injunction fails, or although an injunction is not competent from
circumstances which have occurred since the filing of the
bill."
It will be observed that the British statute does not touch
Page 105 U. S. 212
the question of the account of profits by an infringer, leaving
that as it stood before the passage of the act. The unavoidable
inference is that damages can only be given under the act in cases
in which an account might be decreed, and that the patentee must,
as it was expressly decided by the House of Lords, in
De Vitre
v. Betts, Law Rep. 6 H.L. 319, in all cases when he has a
decree, elect whether he will have an account of profits or an
inquiry as to damages, and cannot have both. Under the act of
Congress of 1870, he may recover damages in addition to the profits
to be accounted for by the defendant; but as the recovery is
limited by the act to the actual damages, it is manifest that the
recovery of damages and profits is not intended to be double, but
that when necessary, the damages are to supplement that loss of the
complainant which the profits found to have been received are
insufficient to compensate, subject to the power of the court as to
their increase, as in case of verdicts.
This firm and indisputable doctrine of the English chancery has
been recognized and declared by this Court, in
Hipp v.
Babin, 19 How. 271, to be part of the system of
equity jurisprudence administered by the courts of the United
States, founded not only upon the legislative declaration in the
Judiciary Act of 1789, "that suits in equity shall not be sustained
in either of the courts of the United States in any case where
plain, adequate, and complete remedy may be had at law," but also
upon the intrinsic distinctions between the different jurisdictions
of law and equity. In delivering the opinion of the Court in that
case, Mr. Justice Campbell remarked that
"the practice of the courts of the United States corresponds
with that of the chancery of Great Britain, except where it has
been changed by rule, or is modified by local circumstances or
local convenience,"
and cited the instances in which
"this Court has denied relief in cases in equity, where the
remedy at law has been plain, adequate, and complete, though the
question was not raised by the defendants in their pleadings nor
suggested by the counsel in their arguments."
He then adds:
"And the result of the argument is that whenever a court of law
is competent to take cognizance of a right, and has power to
proceed to a judgment which affords a plain, adequate, and complete
remedy,
Page 105 U. S. 213
without the aid of a court of equity, the plaintiff must proceed
at law, because the defendant has a constitutional right to a trial
by jury."
It was contended in that case that notwithstanding this general
principle, the bill ought to be maintained, because the
complainants, being minors, were authorized to call upon the
defendants, who had intruded into possession of their lands, for an
account as guardians, and that the Court of Chancery was better
fitted to take an account for rents, profits, and improvements, and
might decide the question of title as incidental to the
account.
It reply to these points, Mr. Justice Campbell remarked that
"here are precedents in which the right of an infant to treat a
person who enters upon his estate with notice of his title, as
guardian or bailiff, and to exact an account in equity for the
profits for the whole period of his occupancy, is recognized."
"But," he added,
"in those cases. the title must, if disputed, be established at
law, or other grounds of jurisdiction must be shown. . . . Nor can
the court retain the bill under an impression that a court of
chancery is better adapted for the adjustment of the account for
rents, profits, and improvements. The rule of the court is that
when a suit for the recovery of the possession can be properly
brought in a court of equity and a decree is given, that court will
direct an account as an incident in the cause. But when a party has
a right to a possession which he can enforce at law, his right to
the rents and profits is also a legal right, and must be enforced
in the same jurisdiction. The instances where bills for an account
of rents and profits have been maintained are those in which
special grounds have been stated, to show that courts of law could
not give a plain, adequate, and complete remedy. No instances exist
where a person who had been successful at law has been allowed to
file a bill for an account of rents and profits during the tortious
possession held against him, or in which the complexity of the
account has afforded a motive for the interposition of the Court of
Chancery to decide the title and to adjust the account."
These principles were announced in a case for the recovery of
the possession of real estate held adversely, but they are of
general application, and embrace as well the case of
Page 105 U. S. 214
torts to personalty and infringements of patent and copy
rights.
The distinct ground upon which the opposite view is presented to
us in argument is that the infringer of a patent right is, by
construction of law, a trustee of the profits derived from his
wrong, for the patentee, and that a court of equity, in the
exercise of its acknowledged jurisdiction over trusts and trustees,
will require him to account as trustee without reference to any
other relief. And in support of this contention we are referred to
passages in the judgments of this Court in the cases of
Packet
Co. v. Sickles, Burdell v. Denig, and
Birdsall v.
Coolidge, all of which have been already cited in this
opinion,
supra, pp.
105 U. S.
198-199.
But the inference sought to be drawn from the expressions
referred to is not warranted. It is true that it is declared in
those cases that in suits in equity for relief against
infringements of patents, the patentee, succeeding in establishing
his right, is entitled to an account of the profits realized by the
infringer, and that the rule for ascertaining the amount of such
profits is that of treating the infringer as though he were a
trustee for the patentee in respect to profits. But it is nowhere
said that the patentee's right to an account is based upon the idea
that there is a fiduciary relation created between him and the
wrongdoer by the fact of infringement, thus conferring jurisdiction
upon a court of equity to administer the trust and to compel the
trustee to account. That would be a
reductio ad absurdum,
and, if accepted, would extend the jurisdiction of equity to every
case of tort where the wrongdoer had realized a pecuniary profit
from his wrong. All that was meant in the opinions referred to was
to declare according to what rule of computation and measurement
the compensation of a complainant would be ascertained in a court
of equity, which, having acquired jurisdiction upon some equitable
grounds to grant relief, would retain the cause for the sake of
administering an entire remedy and complete justice, rather than
send him to a court of law for redress in a second action. The rule
adopted was that which the court in fact applies in cases of
trustees who have committed breaches of trust by an unlawful use of
the trust property for their own advantage -- that is, to
Page 105 U. S. 215
require them to refund the amount of profit which they have
actually realized. This rule was adopted not for the purpose of
acquiring jurisdiction, but in cases where, having jurisdiction to
grant equitable relief, the court was not permitted by the
principles and practice in equity to award damages in the sense in
which the law gives them, but a substitute for damages at the
election of the complainant, for the purpose of preventing
multiplicity of suits. And the particular rule was formulated, as
will be seen by reference to the cases already referred to, out of
tenderness to defendants in order to mitigate the severity of the
punishment to which they might be subjected in an action at law for
damages, and because it was thought more equitable merely to
deprive them of the actual profits arising from their wrong than to
make no allowances, in estimating damages, for the cost and expense
of the business in the prosecution of which they had violated the
rights of the complainant. The same reason operated in the
establishment of the similar rule acted upon in the cases of
Hilton v. Woods and
Jegon v. Vivian, already
cited in a previous part of this opinion,
supra, p.
105 U. S. 209.
The rule itself is reasonable and just, though sometimes perverted
and abused. It has been constantly acted upon by the courts. But it
is a rule of administration, and not of jurisdiction, and although
the creature of equity, it is recognized as well at law as one of
the measures, though not the limit, for the recovery of
damages.
The case is not within the principle according to which in
certain circumstances a court of equity decrees a wrongdoer to be a
trustee
de son tort, and exerts its jurisdiction over him
in that character. Where a defendant has wrongfully intermeddled
with property already impressed with a trust, he may be required as
a trustee to account for it, as was done in the case of
People
v. Houghtaling, 7 Cal. 348, because trust property may be
followed wherever it can be traced into whosesoever possession it
comes except that of a
bona fide purchaser without notice.
It is the character of the property, and not the wrong done in
converting or withholding it, that constitutes the wrongdoer a
trustee.
Our conclusion is that a bill in equity for a naked account of
profits and damages against an infringer of a patent cannot be
Page 105 U. S. 216
sustained; that such relief ordinarily is incidental to some
other equity, the right to enforce which secures to the patentee
his standing in court; that the most general ground for equitable
interposition is to insure to the patentee the enjoyment of his
specific right by injunction against a continuance of the
infringement; but that grounds of equitable relief may arise other
than by way of injunction, as where the title of the complainant is
equitable merely, or equitable interposition is necessary on
account of the impediments which prevent a resort to remedies
purely legal, and such an equity may arise out of, and inhere in,
the nature of the account itself, springing from special and
peculiar circumstances which disable the patentee from a recovery
at law altogether or render his remedy in a legal tribunal
difficult, inadequate, and incomplete, and as such cases cannot be
defined more exactly, each must rest upon its own particular
circumstances, as furnishing a clear and satisfactory ground of
exception from the general rule.
The case of
Garth v. Cotton, 1 Dick. 183, furnishes an
interesting and curious illustration of one of the excepted cases.
In that case, Lord Hardwicke sustained a bill in equity in a case
of waste for an account of timber felled and sold, where there
could be no injunction, in favor of a complainant unborn at the
time of its commission, whose estate was a contingent remainder,
supported by a limitation to trustees to preserve it, the defendant
being the owner of a prior term of years, and the ultimate
remainderman in fee. The Lord Chancellor proceeded on the ground of
collusion between the defendants and a nominal or imputed breach of
trust on the part of the trustees to preserve the contingent
remainder in permitting the wrong, and distinguished the case from
Jesus College v. Bloom, 3 Atk. 262, particularly on the
ground that the complainant could have no remedy at law. Another
instance of an exception is mentioned by Vice-Chancellor Page-Wood
in the extract from his judgment in the case of
Smith v. The
London & Southwestern Railway Co., Kay 408, contained in a
previous part of this opinion.
It does not appear from the allegations of the bill in the
present case that there are any circumstances which would
Page 105 U. S. 217
render an action at law for the recovery of damages an
inadequate remedy for the wrongs complained of, and as no ground
for equitable relief is presented, we are of opinion that the
circuit court did not err in sustaining the demurrer and dismissing
the bill.
Decree affirmed.
MR. JUSTICE GRAY did not sit in this case nor take any part in
deciding it.
