The invention patented to Charles G. Am Ende by letters patent
No. 181,024, dated August 15, 1876, which
"had for its object to combine the
Page 152 U. S. 562
various advantages of cotton fiber with those possessed by
boracic acid and glycerine for preserving animal and vegetable
matter from decay,"
was useful, novel, and patentable, and was described in the
application and specification in sufficiently full, clear, and
exact terms to enable an intelligent chemist reading that
description of it to construct and use it.
In estimating the profits derived from the unlawful manufacture
and sale of a patented invention, the infringer should not be
allowed interest on the capital invested in his plant unless it
appears that the plant was used solely for the manufacture or sale
of the patented article, or the evidence be such as to enable the
master to satisfactorily apportion the interest between the several
kinds of business.
If the infringer be a corporation, salaries of its officers
should not be allowed in estimating such profits where it does not
appear that they have been actually paid.
Charles G. Am Ende, a citizen of the State of New Jersey, filed
a bill of complaint in the Circuit Court of the United States for
the Southern District of New York against Seabury & Johnson, a
corporation of the State of New York, in which he alleged that he
was the patentee and owner of letters patent of the United States
dated August 15, 1876, and numbered 181,024, for an improvement in
borated cotton, and that the defendant corporation, in disregard of
his rights, was engaged in making and vending borated cotton made
in accordance with the method described in said letters patent. The
defendant corporation, by its answer, raised the issues of novelty
and patentability, which were determined in favor of the
complainant, and the case resulted in a decree restraining the
defendant from further infringement and awarding the complainant
the sum of $2,349.15, with costs, from which decree this appeal was
taken.
Page 152 U. S. 564
MR. JUSTICE SHIRAS, after stating the facts in the foregoing
language, delivered the opinion of the Court.
The specification and claim of the patentee were in the
following terms:
"This invention has for its objects to combine the various
Page 152 U. S. 565
advantages of cotton fiber with those possessed by boracic acid
and glycerine for preserving animal and vegetable matter from
decay."
"Heretofore, boracic acid has been used as a preservative agent
in a fluid state and also as a powder. In use, the matter to be
preserved had to be immersed in the solution of boracic acid or
completely covered with the powder. In either case, a very large
quantity of boracic acid was used."
"My present invention, which consists in saturating cotton fiber
with boracic acid and glycerine in a manner hereinafter described,
enables me to apply a very small proportion of boracic acid and
glycerine to the cotton fiber with fully as good an effect as
though the matter to be preserved were entirely embedded in large
quantities of the solution or powder. It enables me at the same
time to utilize the germ-filtering properties of the cotton and its
elasticity as a superior material for packing or covering delicate
tissue."
"I produce my improved borated cotton as follows: I first
prepare a solution of boracic acid in the usual manner and add
thereto a small proportion of glycerine. For the preservation of
tender substances, such as veal, I may also add from ten to forty
percent of soda or potash, never sufficient, however, to reach
neutrality. The cotton, either in bulk or wadding, is next immersed
in the solution until well impregnated therewith, and then pressed,
to discharge all surplus solution or so much thereof as may be
required. The cotton is then dried and ready for use."
"When applied to the material to be preserved either as a
covering or as a wrapping or packing, the cotton will constitute a
filter for keeping germs of putrefaction from passing through, and
the boracic acid absorbed by the cotton will at the same time
preserve the surfaces from decay and counteract all injurious
influences of germs or other elements of destruction already in
contact with such surfaces."
"The glycerine is added to increase the preserving power of the
borated cotton. It renders the cotton slightly hygroscopic, thus
aiding in the diffusion of the acid and in the preservative effect
of the prepared cotton. "
Page 152 U. S. 566
"I have found that the impregnated fiber shows, even under a
good microscope, no difference from a fiber not impregnated with
boracic acid, and that therefore, although a very thin film of acid
may adhere to the exterior surface of the fiber, the main
proportion of the acid is absorbed by and diffused within the
fibers. In consequence, the acid can in use be but gradually
released from the fiber, and will thus produce a constant and
lasting effect."
"I claim:"
"The borated cotton, being cotton fiber, which is saturated with
boracic acid and glycerine, substantially as herein shown and
described."
The first ground of defense relied on is that the patentee has
failed to describe his invention in such full, clear, and exact
terms as to enable persons reading the description of the invention
to construct and use it, and it is contended that the strength of
the boracic acid solution is not prescribed, nor the precise
proportion of glycerine. In considering this objection, it must be
remembered that the description is addressed to persons skilled in
the art to which it relates. The solution of boracic acid is
referred to not as anything new, but as an article well known to
druggists and physicians, and when the patentee says that he
"prepares a solution of boracic acid in the usual manner," he means
as it has formerly and customarily been prepared. When he directs
that a small proportion of glycerine shall be added, it is obvious
that the quantity of the glycerine is to vary with the amount of
cotton and boracic acid used, but that the merits of the invention
will not depend on whether in a given case a little more or less
glycerine is used. Such general directions are common in the arts,
as appears in some of the very publications introduced by the
defendant to show anticipation. Thus in the Druggists' Circular and
Chemical Gazette, it is stated that Dr. Edmunds had used "a
solution of boracic acid," and in the Journal de Pharmacie it is
said that, in making his dressing, Prof. Gulber saturated his
wadding with "a certain quantity of glycerine," and his formula is
thus given: "It is only necessary to pour a small quantity of
glycerine over the square sheet," etc.
Page 152 U. S. 567
We therefore agree with the court below in thinking that
"intelligent chemist, setting out properly to combine the
enumerated ingredients into which the cotton is to be immersed, and
with which it is to be impregnated, could hardly go astray."
It is also to be observed that neither the defendant, in making
the infringing article, nor the several witnesses of eminence in
the medical profession who testified to the practical value of the
patented dressing, seem to have had any difficulty in understanding
and applying the description contained in the patent.
In
Loom Co. v. Higgins, 105 U.
S. 580, where the sufficiency of a description was in
question, it was held that a specification in letters patent is
sufficiently clear and descriptive when expressed in terms
intelligible to a person skilled in the art to which it
relates.
The next contention is that as the plaintiff's patented dressing
was composed of materials whose specific virtues and modes of
operation were well known, there was no invention shown in
combining them in the manner described. It is indeed true that the
patentee did not claim to have been the first to suggest the use of
cotton fiber as a means of excluding germs from wounds or from the
article to be protected. Nor did he claim to have first discovered
the antiseptic qualities of boracic acid or the hygroscopic
property of glycerine. But the patentee was the first to perceive
that by combining these articles in the manner he pointed out,
there would be formed a convenient and permanent dressing with the
desirable qualities of the several constituents. The complainant's
evidence satisfactorily shows that in such a dressing, the cotton
acts as a screen to exclude germs, and as a vehicle to hold the
other ingredients; that the boracic acid possesses marked
antiseptic qualities, but is liable, if used alone, to dry on the
cotton and to form crystals, which impair the antiseptic qualities
of the acid and which mechanically scratch or irritate the
sensitive surface of a wound, and that the glycerine, owing to its
property of absorbing moisture from the atmosphere, keeps the
boracic acid from hardening or crystalizing and, besides, adds
somewhat to the healing and preservative power of the dressing.
Page 152 U. S. 568
The merits of the complainant's invention received immediate and
widespread recognition, and the article came into use not only to
protect animal substances for alimentary purposes, but, and
chiefly, to protect wounds from infection and suppuration. It was
introduced into hospitals and into the private practice of
physicians, and in fact has become a staple article for medicinal
purposes.
But it is further contended that there was no novelty in
complainant's invention because it had been anticipated by others.
To sustain this contention, the defendant put in evidence an
article published in the American Journal of Pharmacy for November,
1871 at 516, where it is stated that Prof. Gubler, at a recent
meeting of the Academy of Medicine, had exhibited some specimens of
wadding prepared by saturating it with a certain quantity of
glycerine, which he had found to render it permeable to all
medicinal liquids without causing it to lose any of its suppleness
and lightness; also an article in the same journal for March, 1867
at 149 wherein Dr. Adolphus stated that,
"applied to suppurating surfaces which are painful and produce
an ichorous pus, glycerine dressings change the abnormal condition
by arresting the degenerating process through its antiseptic and
astringent properties."
The defendant likewise put in evidence a copy of the Druggists'
Circular and Chemical Gazette for June, 1875, wherein there is an
account of treatment by Dr. Edmunds, in the case of an amputated
thigh, by a dressing of lint steeped in a hot solution of boracic
acid, with most satisfactory results in preventing putrefactive
discharge.
Undoubtedly this evidence shows that the specific qualities of
glycerine and of boracic acid were known and that those articles
had been successfully used in the instances narrated. But we agree
with the court below in thinking that
"this evidence does not disclose that anyone prior to Am Ende
accomplished what he has described and claimed; that the fact that
others had done something quite similar, and had used separately,
or in different combinations, the ingredients of his claim should
not affect his patent. All that is described in the prior
publications the defendant may use with perfect
Page 152 U. S. 569
immunity. They may use 'lint steeped in a hot saturated solution
of boracic acid,' or 'wadding saturated with a certain quantity of
glycerine,' or boracic acid dissolved in glycerine, but they should
not be permitted to use cotton combined with a solution of boracic
acid and glycerine in the manner described in the specification,
for that belongs to Am Ende."
Errors are complained of in the action of the court below in
overruling defendant's exceptions to the master's report. So far as
those exceptions are based on the computations and findings of the
master, under the evidence before him, as to the profits made by
the defendant, we see no reason to differ with the court below in
overruling them. The claim that the appellant should be allowed, as
part of the cost of the borated cotton during the period covered by
the accounting, interest in plant and capital invested, calls for
more particular notice.
A similar claim was disallowed in the case of
Rubber
Co. v. Goodyear, 9 Wall. 804, but it is claimed
that in
Manufacturing Co. v. Cowing, 105
U. S. 257, such an item was allowed. In the latter case,
which this Court styled an "exceptional one," it was said that in
charging the defendant with profits, he should be allowed for "the
use of tools, machinery, power, and other facilities employed in
the manufacture." It may be, as was observed by the court below in
the present case, that it did not appear in
Manufacturing Co.
v. Cowing but that the use of the tools, machinery, and power
was a hired use. At any rate, in that case, the infringement
consisted in making and selling a pump, which was the only one that
could successfully compete with that controlled by the patent, and
the machinery was used for no other purpose. In the present case,
the defendant's plant and real estate were used for several other
and wholly different kinds of manufacture than the patented
article, and the evidence offered to distinguish between the
profits derived from the use of the plant and real estate for
making the borated cotton and those attributable to the other
sources of profit was not sufficient to enable the master to make a
satisfactory apportionment or allowance for interest on the
investment.
We do not wish to be understood as holding that in no case
Page 152 U. S. 570
where the plaintiff's damages are measured by the defendant's
profits ought there to be allowance in the latter's favor of
interest on the money invested in the plant. Nor do we say that
such an allowance may not be properly made, even where the use of
the plant is not wholly restricted to making the infringing
article. But the evidence in such a case should enable the master
to satisfactorily apportion the interest between the several kinds
of business.
The appellant further complains of the action of the master in
disallowing the sum of $15,000 per annum for salary of the
President of the defendant company. The defendant introduced
evidence tending to show what would be reasonable compensation for
such services as were performed by the President, but did not show
what sum or that any sum was actually paid him. To have allowed
salaries which had never been paid would have been, as was said in
Rubber Co. v. Goodyear, to permit a dividend of profits
under the guise of salaries.
Other exceptions that were taken to the master's report were
satisfactorily disposed of by the court below, and do not call for
further discussion.
The decree of the circuit court is accordingly
Affirmed.
