An examination of the history of the appellant's claim shows
that, in order to get his patent, he was compelled to accept one
with a narrower claim than that contained in his original
application, and it is well settled that the claim as allowed must
be read and interpreted with reference to the rejected claim and to
the prior state of the art, and cannot be so construed as to cover
either what was rejected by the Patent Office or disclosed by prior
devices.
This Court concurs with the court below in holding that the
cartridges made and used by the United States were not within the
description contained in the appellant's claim.
On December 28, 1878, William Wheeler Hubbell filed in the
United States Patent Office an application for a patent for an
improvement in metallic cartridges, and on February 18, 1879,
letters patent No. 212,313 were granted and issued to him.
Page 179 U. S. 78
On April 19, 1883, Hubbell, the patentee, filed a petition in
the Court of Claims against the United States, alleging that the
latter were using his patented methods in circumstances that
warranted a claim for compensation. This case was numbered in the
Court of Claims as No. 13,793, and was so proceeded in that, on
June 1, 1885, judgment was entered in the Court of Claims
dismissing the petition. 20 Ct.Cl. 354. In August, 1885, an
application for allowance of an appeal from that judgment to this
Court was filed. Pending this application, Hubbell brought another
suit against the United States in the Court of Claims by filing a
petition, No. 16,261, on June 11, 1888, presenting substantially
similar issues to those asserted in the first suit.
On December 23, 1895, judgment was entered by the Court of
Claims dismissing the petition in the second case. 31 Ct.Cl. 464.
On March 20, 1896, an application for allowance of an appeal from
this judgment to this Court was filed, and on July 6, 1896, this
appeal was allowed. On May 31, 1898, the judgment of the Court of
Claims dismissing the petition in the second case was approved by
this Court.
171 U. S. 171 U.S.
203.
On June 7, 1898, the application for allowance of appeal in the
first case was allowed, and on May 31, 1898, a petition was allowed
to be filed in this Court for a rehearing in the second case. The
appeal in the first case and the petition for a rehearing in the
second case were argued together in this Court on January 9,
1900.
MR. JUSTICE SHIRAS, delivered the opinion of the Court.
It is contended, on behalf of the appellant, that we should
Page 179 U. S. 79
regard the present case and the case disposed of upon the former
appeal, in
171 U. S. 171 U.S.
203, as constituting substantially one controversy, and that we
should give the appellant the benefit of the new or additional
facts which, it is claimed, were made to appear by the amended
findings in the first case. It is claimed, on the part of the
United States, that the former decision of this Court was a final
adjudication of the controversy, that its finality was not affected
by the subsequent allowance by the trial court of an appeal from
the former judgment, and that at all events, the additional
findings were, in substance, not different from those previously
made, and, even if now considered, show no sufficient grounds for
reversing the judgment of the Court of Claims in the present case,
or that of this Court on the first appeal.
Whether, if the additional findings of the trial court had
presented a new and meritorious case, this would afford a
sufficient reason for this Court to set aside its previous judgment
and to enter upon a consideration of the controversy
de
novo we do not decide, as, even upon such an assumption, we
agree with the court below in thinking that the new findings did
not make a new or different case, or impair the legal foundation of
the judgment rendered in the case in which they were made.
Those findings, as we find them printed in the record of the
case at No.198 of the October Term, 1897, of this Court, consist
partly of matters connected with the claim on account of the
manufacture and use of the cupanvil cartridge, and, as the claimant
filed a waiver of that claim, such parts of the findings have no
relevancy now. Other portions of the additional findings bear on
the number of cartridges made by the United States, so as to afford
a basis for estimating the damages, if the claimant should recover,
and do not affect the legal questions involved. Other of the
findings allowed reference to certain drawings filed by the
claimant in previous applications made by him in the Patent Office,
which may have some relevancy as disclosing the history of the art,
but do not appear to materially affect the construction of the
claim finally allowed by the Patent Office, and the same may be
said of some verbal amendments allowed to the findings previously
made.

An examination of the history of the appellants' claim, as
disclosed in the file wrapper and contents, shows that, in order to
get his patent, he was compelled to accept one with a narrower
claim than that contained in his original application, and it is
well settled that the claim as allowed must be read and interpreted
with reference to the rejected claim and to the prior state of the
art, and cannot be so construed as to cover either what was
rejected by the Patent Office or disclosed by prior devices.

It is quite true that, where the differences between the claim
as made and as allowed consist of mere changes of expression,
having substantially the same meaning, such changes, made to meet
the views of the examiners, ought not to be permitted to defeat a
meritorious claimant. While not allowed to revive a rejected claim
by a broad construction of the claim allowed, yet the patentee is
entitled to a fair construction of the terms of his claim as
actually granted. The specification, as amended, contained the
following description:
"The distinguishing feature of my invention is the organized
construction to carry into complete effect the expressed principles
of operation of the fulminate of mercury or detonating powder and
the powder charge. In this organization, the fulminate, although
the superior explosive force, is contracted into a diminished or
small central chamber, and fills it. The flange and head of the
metallic case are solid, all in one piece. This chamber at its
sides or outer extreme edges communicates directly and exclusively
with the powder charge, so that the explosive force of the
fulminate is not allowed to expand under a larger area of the anvil
plate and blow it out, but is compelled to diffuse its explosive
force not in a central stream, but in a diffused body into the base
of the powder charge. To effect this, the central anvil piece has
no central aperture, is as wide as the fulminate-filled chamber,
and the perforations are at the extreme outer sides of this
fulminate, for two purposes: one is to diffuse the fire from this
center most thoroughly; the other is to have an unperforated anvil
over and against the fulminate, as it rests solid in its chamber,
to receive the central blow of a
Page 179 U. S. 81
striker and obtain complete resistance by the anvil bar, and yet
have free escapement for the explosive force at once from beneath
the anvil plate without any chamber or space for it to expand into
under the plate. This assures a certain ignition, security of the
anvil plate to keep its position, and a complete combustion of the
powder charge from the base forward, as it impels the bullet out of
the gun."
The claims made in the application were as follows:
"1st. The circular plate E, constructed with central solid
resisting piece
i, and two or more side perforations
k
k, substantially as described, applied within a metal case,
with cylinder and rear end solid and tight, thereby requiring the
insertion of the plate and charge and priming from the front,
igniting the charge and remaining fire-tight in firing as
described."
"2d. The circular plate E, constructed as described, in
combination with the circular disc D, and metal solid fire-tight
case A, substantially as shown and described."
"3d. A circular metallic tight-fitting plate, perforated into a
central fulminate chamber, leaving a central solid or unperforated
bar over the fulminate chamber, within a solid fire-tight metal
case, substantially as set forth."
The examiners rejected these claims on reference to prior
patents. Thereupon the claimant, having amended his specification
as above, substituted for the three claims above copied the
following:
"What I claim as new and desire to secure by letters patent is
--"
"The construction and arrangement of the chamber of fulminate,
anvil, plate, perforations, and case, with the central constructed
filled chamber of fulminate powder in contact and between the base
of the case and the circular anvil plate, with central anvil bar
and two or more side perforations, extending from the extreme sides
of the chamber of fulminate into the base of the powder charge,
whereby the smallest area of resistance is presented to the
fulminate explosion, and the fire is diffused in the base of the
charge of powder, and the greatest resistance is presented by the
front face of the plate to the powder
Page 179 U. S. 82
charge, consuming the powder and securing the plate as and by
the means described."
The examiners held that the construction described in the
amended specification involved patentable novelty, and that a
specific and well defined claim might be allowed, but not the
amended claim, it being "vague, indefinite, and ambiguous." The
claimant thereupon withdrew the above amended claim, and
substituted another, which was finally allowed, in the following
terms:
"What I claim as new and desire to secure by letters patent is
--"
"In the bottom of a solid metallic flange cartridge case or
shell, the combination of a circular base enclosing a central
chamber of fulminate provided with two or more openings, whose
inner edges nearly coincide with the edges of the central chamber
of fulminate in the base of the cartridge, substantially as
described."
It is obvious that this is a claim for a combination none of the
elements or constituent parts of which is claimed to be new, but
whose merit consists in such an adjustment and relation of the
parts as to produce the desired effect.
"In such a claim, if the patentee specifies any element as
entering into the combination, either directly by the language of
the claim or by such a reference to the descriptive part of the
specification as carries such element into the claim, he makes such
element material to the combination, and the court cannot declare
it to be immaterial. It is his province to make his own claim, and
his privilege to restrict it. If it be a claim to a combination,
and be restricted to specified elements, all must be regarded as
material, leaving open only the question whether an omitted part is
supplied by an equivalent device or instrumentality."
Fay v. Cordesman, 109 U. S. 408.
"In patents for combinations of mechanism, limitations and
provisos imposed by the inventor, especially such as were
introduced into an application after it had been persistently
rejected, must be strictly construed against the inventor and in
favor of the public, and looked upon as in the nature of
disclaimers."
Sargent v. Hall Safe & Lock Co., 114 U. S.
63.
Page 179 U. S. 83
"If an applicant, in order to get his patent, accepts one with a
narrower claim than that contained in his original application, he
is bound by it. If dissatisfied with the decision rejecting his
application, he should pursue his remedy by appeal."
Shepard v. Carrigan, 116 U. S. 593.
When the rejected claims and the one finally allowed are
compared, it will be perceived that they all describe the
combination as consisting of a circular base, containing a central
chamber of fulminate, the anvil over it, with two or more
perforations to permit the fire or explosive force of the fulminate
to be communicated to the powder charge. What, then, was the
difference or modification which resulted in the allowance of a
claim? We agree with the court below in finding that difference in
the position of the apertures or vents. The examiners refused to
allow the claim until the claimant distinctly located the vents as
"openings whose inner edges nearly coincide with the edges of the
central chamber of fulminate in the base of the cartridge," thereby
making the relative position of the vents and the walls of the
fulminate chamber a material part of the claimant's patent.
Breech-loading metallic cartridges were not new, and it was the
opinion of the examiners that, in merely claiming
"a circular metallic tight-fitting plate perforated with a
central fulminate chamber, leaving a central solid or unperforated
bar over the fulminate chamber within a solid fire-tight metal
case,"
the claimant was anticipated by the patents of Moffat, 53,168,
March 13, 1866; of Tibbals, 90,607, May 25, 1869, and by an English
patent, 2,906, 1865. It was not until the claimant specifically
claimed, as part of his combination,
"an anvil over the fulminate provided with two or more openings
whose inner edges nearly coincide with the edges of the central
chamber of fulminate in the base of the cartridge,"
that the patent was allowed. Whether the examiners were right or
wrong in so holding, we are not to inquire, as the claimant did not
appeal, but amended his claim and accepted a grant thereof, thereby
putting himself within the range of the authorities which hold
that, if the claim to a combination be restricted to specified
elements, all must be regarded as material, and that limitations
imposed by the inventor, especially
Page 179 U. S. 84
such as were introduced into an application after it had been
persistently rejected, must be strictly construed against the
inventor and in favor of the public, and looked upon as in the
nature of disclaimers.
"It may be observed . . . that the courts of this country cannot
always indulge the same latitude which is exercised by English
judges in determining what parts of a machine are or are not
material. Our law requires the patentee to specify particularly
what he claims to be new, and if he claims a combination of certain
elements or parts, we cannot declare that any one of these elements
is immaterial. The patentee makes them all material by the
restricted form of his claim."

Desper, 101 U. S. 332,

Co., 152 U. S. 425,

With these principles of construction in view, we are
constrained to concur with the court below in holding that the
cartridges made and used by the government were not within the
description contained in the appellant's claim.
The government cartridges alleged to be within the appellant's
patent are of two kinds -- one called the "cup-anvil cartridge,"
the other the "reloading cartridge." As the appellant has withdrawn
his claim for infringement of the former, we have only to do with
the latter or reloading cartridge. It is thus described in the
sixth finding of the court below:
"This cartridge is a hollow metallic shell, rimmed around the
base with a pocket in the exterior of the center of the base;
through the center of the top of this pocket, supposing the
cartridge to be stood upon its base or closed end, is pierced a
single aperture or hole to carry the fulminate flame to the black
powder chamber. This cartridge contains only the black powder and
the bullet. Any one of the several different kinds of primers may
be used in it -- the one used by the United States and alleged to
infringe claimant's rights is a circular metallic cup, into which
is put the fulminate -- above this is fastened a disk or cover
having a groove on its upper side, being the diameter of the
circle; at each end of this groove a small piece or notch is cut
out of it; through the holes thus formed, the flame from the
fulminate escapes; if this primer is placed in the chamber of the
reloading
Page 179 U. S. 85
cartridge, with the closed end of the cup outwards and the
grooved end against the top of the chamber, the flame from the
fulminate, when exploded, would pass through these holes or
notches, thence along the groove to the central aperture in the
cartridge case or shell, thence to the black powder chamber through
this single aperture. The entire area of each of the holes or
notches in the disk is over the fulminate chamber, and the portion
of the disk between the holes is the anvil.."
This finding is claimed by the appellant to be incorrect in
several respects, and particularly in its statement that "the
portion of the disk between the holes is the anvil."
But even if we were permitted as an appellate court to depart
from the findings of fact made by the trial court, we do not
perceive that the particulars in which this finding is objected to
really affect the case as presented to us. Even if we were to adopt
the description of the government's cartridge given by the
appellant, it still appears that there is an essential difference
between the two types of cartridge. Without accepting or rejecting
the government's contention that the government's cartridge is
outside primed and the appellant's inside primed, and wherein it is
claimed that for reloading purposes an outside primed cartridge is
superior, it is sufficient to say that the difference in the shape
and position of the vents, whereby the explosive force of the
fulminate is communicated to the powder charge, is obvious.
The distinguishing feature of the appellant's cartridge is that
the anvil plate has two or more openings whose inner edges nearly
coincide with the edges of the central chamber of fulminate; but,
in the reloading cartridge of the government, the vents are wholly
over the fulminate chamber, do not lead directly to the powder
chamber, but lead to a channel cut across the upper face of the
anvil, and by this to a hole in the base of the powder chamber.
By this latter construction, the explosive force of the
fulminate enters the powder chamber in a central stream. But the
appellant specifies as a distinguishing feature that the
fulminate
"chamber at its sides or outer extreme edges communicates
directly and exclusively with the powder charge, so that the
explosive force of the fulminate is not allowed to expand under
a
Page 179 U. S. 86
larger area of the anvil plate and blow it out, but is compelled
to diffuse its explosive force not in a central stream, but in a
diffused body into the base of the powder charge."
It may be, as the appellant contends, that his method of
communicating the explosive force of the fulminate to the powder
charge is an improvement on previous methods, and is superior in
efficacy to that used in the government's cartridges, but our
inquiry is not as to the merits of the patent in suit, but is
confined to the question whether it covers, in legal contemplation,
the defendant's cartridge.
Some contention is made in argument that, because it is stated
that some grains of powder may and do fall down through the base of
the defendant's powder chamber, and lie loosely in the groove
across the upper face of the anvil, therefore it must be concluded
that such loose grains of powder come directly in contact with the
flame of the fulminate before the latter enters the powder chamber.
But such a fact, if it be a fact, appears to be immaterial. It is
not pretended that these few loose grains of powder are relied on,
or in fact operate, as a means of igniting the charge in the powder
chamber.
Nor can we accept the contention that these two combinations are
identical because they are intended to obtain the same result. What
we have to consider is not whether the end sought to be effected is
the same, but whether the devices or mechanical means by which the
desired result is secured are the same.
We do not consider it necessary to consider a further
suggestion, contained in the opinion of the court below, that, even
if the relative position of the vents and the wall of the fulminate
chamber be not a material part of the claimant's patent, still the
claimant cannot recover because the other characteristics of his
invention, found in the cartridge now used by the defendants, were
introduced by them prior to the application for or issue of the
patent.
The decree of the Court of Claims, dismissing the claimant's
petition, is
Affirmed.
