If a suit in equity to restrain from infringing letters patent
and to recover profits and damages be commenced so late that under
the rules of the court, no injunction can be obtained before the
expiration of the patent, the bill should be dismissed for want of
equity jurisdiction; but if it be begun in such time that an
injunction can be obtained before the expiration
Page 119 U. S. 323
of the patent, although only three days remain for it to run, it
is within the discretion of the court to take jurisdiction, and if
it does so, it may, without enjoining the defendant, proceed to
grant the other incidental relief sought for.
This Court will not assume without proof that a reissue made
fourteen years after the issue of the original patent enlarges the
original claim, or that it was sought for the purpose of enlarging
it.
Thompson v. Wooster, 114 U. S. 104,
affirmed and applied.
Established license fees are the best measure of damages in
suits for infringing patents.
This was a bill in equity for infringing a patent for an
invention. The case is stated in the opinion of the Court.
MR. JUSTICE BRADLEY delivered the opinion of the Court.
This is a suit on a patent, brought by Wooster, the appellee,
against the persons composing the firm of Johnson, Clark & Co.,
of New York, to restrain them from infringing the patent and to
recover profits and damages. The bill was filed on the 20th of
December, 1879, and the patent expired fifteen days afterwards. The
patent was for folding guides used on sewing machines, and is the
same that was involved in the case of
Thomson v. Wooster,
114 U. S. 104. It
was granted to one Douglas in October, 1858, for a period of
fourteen years, was extended in October, 1872, for seven years
longer, and was then, in the same month, surrendered and reissued.
The bill does not specify the particular ground on which the
reissued patent was granted, and although the answer avers that it
was unlawfully granted, that the original was surrendered for the
purpose of claiming more and other things than were described and
claimed in it, and that the reissued patent is not for the same
invention for which the original was granted, it does not set out
the original, nor was the original put in evidence in the cause,
and no evidence was offered to substantiate
Page 119 U. S. 324
the allegations of the answer. The complainant produced the
reissued patent in evidence and proved infringement. The defendant
adduced evidence before the examiner, but out of time, and it was
ruled out by the court. A decree was made establishing the patent
and the infringement thereof by the defendants and referring it to
a master to take and state an account of profits, and to assess
damages, and the defendants were ordered to produce their books,
papers, and devices used so far as related to the matter in issue.
Upon this reference, the parties entered into a stipulation before
the master by which the defendants admitted that they had purchased
and disposed of 15,000 folding guides covered by the decree, and in
consideration thereof the complainant waived all further testimony
as to profits received by the defendants therefrom and agreed to
rely on proof of damages in place of profits. The complainant
adduced evidence to show that he had an established license fee of
ten cents for each folding guide purchased or disposed of, and has
granted licenses at that rate to divers sewing machine companies.
The master, being satisfied with this evidence, reported the
damages at $1,500. The defendants filed a number of exceptions to
the report, none of which was sustained, and a decree was entered
for the amount of damages reported. The defendants thereupon
appealed.
The points taken by the appellants are:
First, that the court below, sitting as a court of equity, had
no jurisdiction of the case, because the complainant had a plain
and adequate remedy at law.
Second, that the reissue of the patent was illegal by reason of
laches in applying for it.
Third, that the court erred in finding that the measure of
damages was an established license fee, and that such license fee
was proved.
As to the first point, the bill does not show any special ground
for equitable relief except the prayer for an injunction. To this
the complainant was entitled, even for the short time the patent
had to run, unless the court had deemed it improper to grant it.
If, by the course of the court, no injunction could have been
obtained in that time, the bill could very
Page 119 U. S. 325
properly have been dismissed, and ought to have been. But by the
rules of the court in which the suit was brought, only four days'
notice of application for an injunction was required. Whether one
was applied for does not appear. But the court had jurisdiction of
the case, and could retain the bill if, in its discretion, it saw
fit to do so, which it did. It might have dismissed the bill if it
had deemed it inexpedient to grant an injunction; but that was a
matter in its own sound discretion, and with that discretion it is
not our province to interfere unless it was exercised in a manner
clearly illegal. We see no illegality in the manner of its exercise
in this case. The jurisdiction had attached, and although, after it
attached, the principal ground for issuing an injunction may have
ceased to exist by the expiration of the patent, yet there might be
other grounds for the writ, arising from the possession by the
defendants of folding guides illegally made or procured while the
patent was in force. The general allegations of the bill were
sufficiently comprehensive to meet such a case. But even without
that, if the case was one for equitable relief when the suit was
instituted, the mere fact that the ground for such relief expired
by the expiration of the patent would not take away the
jurisdiction and preclude the court from proceeding to grant the
incidental relief which belongs to cases of that sort. This has
often been done in patent causes, and a large number of cases may
be cited to that effect, and there is nothing in the decision in
Root v. Railway Co., 105 U. S. 189, to
the contrary.
American Cotton Tie Co. v. Simmons,
106 U. S. 89;
Lake Shore &c. Railway v. Car Brake Co., 110 U.
S. 229;
Consolidated Valve Co. v. Crosby Valve
Co., 113 U. S. 157;
Thomson v. Wooster, 114 U. S. 104. It
is true that where a party alleges equitable ground for relief and
the allegations are not sustained, as where a bill is founded on an
allegation of fraud which is not maintained by the proofs, the bill
will be dismissed
in toto, both as to the relief sought
against the alleged fraud and that which is sought as incidental
thereto.
The point insisted on, that the bill contained no charge of
continued infringement or of infringement at the time of commencing
the suit, if it were material, is not sustained by the fact. The
bill does contain such a charge.
Page 119 U. S. 326
As the court had jurisdiction at the inception of the suit, even
though upon a narrow ground, yet as the defendants did not ask the
dismissal of the bill on the ground of want of jurisdiction, we
should be very reluctant, if we had the power, now, on an appeal,
after the case has been tried and determined, to reverse the
decree.
The second point raised was substantially disposed of in the
case of
Thomson v. Wooster, qua supra. The allegations in
the present bill are the same as they were in that case. Neither
the bill nor the proofs show anything from which the court can
infer that the reissue was illegally granted, and the allegations
of the answer are unsupported by evidence. The reissued patent
itself made a
prima facie case for the complaint. The
allegations of the answer that it was issued for the mere purpose
of expanding the claim of the original and that it was for another
and different invention should have been proved. But we have no
evidence on the subject -- not even the original patent with which
to compare the reissue. This point therefore is wholly without
foundation.
The third point, as to the measure of damages and the want of
proof thereof, is equally untenable. It is a general rule in patent
causes that established license fees are the best measure of
damages that can be used. There may be damages beyond this, such as
the expense and trouble the plaintiff has been put to by the
defendant and any special inconvenience he has suffered from the
wrongful acts of the defendant, but these are more properly the
subjects of allowance by the court under the authority given to it
to increase the damages.
As to the sufficiency of the proof, we see no occasion to
disturb the conclusion reached by the master on this point. The
complainant proved several instances of licenses given by him to
large sewing-machine companies, the fees on which were regularly
paid and corresponded with the rate allowed by the master. We think
that the defendants have no occasion to complain of the amount
awarded.
The decree of the circuit court is affirmed.
