Letters patent No. 298,303, issued May 6, 1884, to George
Krementz for a new and improved collar button, protect a patentable
invention, which was not anticipated by the invention described in
letters patent No. 171,882,
Page 148 U. S. 557
issued to Robert Stokes January 4, 1876, nor by the invention
described in letters patent No. 177,253, issued May 9, 1876, to
John Keats.
When the other facts in the case leave the question of invention
in doubt, the fact that the device has gone into general use, and
has displaced other devices which had previously been employed for
analogous uses, is sufficient to turn the scale in favor of
invention.
In equity to restrain the infringement of letters patent. Decree
dismissing the bill, from which plaintiff appealed. The case is
stated in the opinion.
MR. JUSTICE SHIRAS delivered the opinion of the Court.
This is an appeal from a decree of the Circuit Court of the
United States for the Southern District of New York dismissing a
bill filed to restrain the infringement of letters patent of the
United States, No. 298,303, granted May 6, 1884, to George
Krementz, of Newark, N.J. for a new and improved collar button.
Commplainant's evidence, tending to show that the collar button
made by the defendants was within the claim of the patent in suit
and constituted an infringement was not contradicted or disputed,
but it was held by the court below that the patent was invalid for
want of novelty. 39 F. 323.
In his specification, the patentee states that his invention
consists in a collar button having a hollow head and stem, the said
button being formed and shaped out of a single continuous plate of
sheet metal. The method or process of making the button is thus
described:
"By means of suitable dies, a metal plate is pressed into the
shape shown in Fig. 2 -- that is, the plate is provided with a
hollow stem, B, the sides of which are pressed together at about
the middle, in some suitable manner, to form a head, C at the end
of the stem, as in Fig. 3. Then the head is pressed towards the
base plate or back, D, whereby the head will be upset, and will
have the shape shown in Figs. 4 and 5. By
Page 148 U. S. 558
this operation the head is hardened. The base plate or back, D,
is then rounded out and finished, and its edge turned over, as
shown in Fig. 5."
In the accompanying diagram, Fig. 1 is a side view of the
completed button. Figs. 2, 3, 4, and 5 are cross-sectional
elevations of the same in the different stages of the operation of
making it.

The advantages attributed to the invention are the doing away
with soldered joints, the lightness of the hollow stem and head, as
compared with buttons having solid stems and heads, and the
cheapness arising from the use of less material, with equal or
superior strength, which, when gold is used, is quite
appreciable.
The learned judge in the court below contented himself with
comparing Krementz's invention with two earlier patents -- one to
Stokes, No. 171,882, granted January 4, 1876, and one to Keats, No.
177,353, granted May 9, 1876 -- in which patents, he thinks, are to
be found the special features claimed by Krementz.
Page 148 U. S. 559
The Stokes patent was for an improvement in making a stud
fastening known as "Thomson's Unbreakable Busk Fastening," and
whereby, instead of fastening the parts of the stud together by
rivets, the entire busk was made out of one piece of metal by
striking up or raising the stud out of a strip of malleable sheet
metal. The structure thus produced is a solid, rivet-like, and flat
head, intended to resist a great strain and evidently not designed
to be used as a collar button, where a well defined round head,
adapted to be used where there is no strain, is necessary and
essential.
In the Keats process, the button is not made of a continuous
piece of sheet metal, but has side seams in the post and has a base
plate composed of two separate parts, and the head is open on the
under side. It could not be used as a collar button, but is
intended to be permanently fastened, either to eyelet holes or to
the fabric with which it is connected.
We cannot see in these devices, taken separately or together, an
anticipation of the Krementz button. Indeed, the court below
concedes that "Krementz was the first to make a stud from a single,
continuous piece of metal, in which the head was hollow and round
in shape."
The learned judge was, however, of the opinion that
"any competent mechanic, versed in the manufacture of hollow
sheet-metal articles, having before him the patents of Stokes and
Keats, could have made these improvements and modifications,
without exercising invention, and by applying the ordinary skill of
the calling."
It is not easy to draw the line that separates the ordinary
skill of a mechanic, versed in his art, from the exercise of
patentable invention, and the difficulty is specially great in the
mechanic arts, where the successive steps in improvements are
numerous and where the changes and modifications are introduced by
practical mechanics. In the present instance, however, we find a
new and useful article, with obvious advantages over previous
structures of the kind. A button formed from a single sheet of
metal, free from sutures, of a convenient shape, and uniting
strength with lightness, would seem to come fairly within the
meaning of the patent laws.
Page 148 U. S. 560
The tools to be used in making the button are not described, but
they are not claimed to be new, and the method or process of
manufacture is described with sufficient particularity to enable
any one skilled in the art to follow it. Buttons made of several
pieces are liable to break at the soldered joints, and it is stated
by an experienced witness that the metal, by the process of
soldering, becomes soft and liable to bend. The different pieces
are set together by hand, and are not always uniform or put
together truly.
The view of the court below, that Krementz's step in the art was
one obvious to any skilled mechanic, is negatived by the conduct of
Cottle, the president of the defendant company. He was himself a
patentee, under letters granted April 16, 1878, for an improvement
in the construction of collar and sleeve buttons, and put in
evidence in this case. In his specification, he speaks of the
disadvantages of what he calls "the common practice to make the
head, back, and post of collar and sleeve buttons separate, and to
unite them by solder." His improvement was to form a button of two
pieces, the post and base forming one piece, and then solder to the
post the head of the button, as the other piece. Yet, skilled as he
was, and with his attention specially turned to the subject, he
failed to see what Krementz afterwards saw -- that a button might
be made of one continuous sheet of metal, wholly dispensing with
solder, of an improved shape, of increased strength, and requiring
less material.
It was also made to appear that the advantages of the new button
were at once recognized by the trade and by the public, and that
very large quantities have been sold.
The argument drawn from the commercial success of a patented
article is not always to be relied on. Other causes, such as the
enterprise of the vendors and the resort to lavish expenditures in
advertising, may cooperate to promote a large marketable demand.
Yet, as was well said by MR. JUSTICE BROWN in the case of
Consolidated Brake-Shoe Co. v. Detroit Co., 47 F. 894,
"when the other facts in the case leave the question of
invention in doubt, the fact that the device has gone into general
use and has displaced other devices which
Page 148 U. S. 561
had previously been employed for analogous uses is sufficient to
turn the scale in favor of the existence of invention."
Loom Co. v. Higgins, 105 U. S. 580, was
a case where the patented device consisted in a slight modification
of existing mechanism, and it was contended that this slight change
did not constitute a patentable invention; but this view did not
prevail, the Court saying:
"It is further argued, however, that, supposing the devices to
be sufficiently described, they do not show any invention, and that
the combination set forth in the fifth claim is a mere aggregation
of old devices, already well known, and therefore it is not
patentable. This argument would be sound if the combination claimed
by Webster was an obvious one for attaining the advantages proposed
-- one which would occur to any mechanic skilled in the art; but it
is plain from the evidence and from the very fact that it was not
sooner adopted and used that it did not for years occur in this
light to even the most skillful persons. It may have been under
their very eyes; they may almost be said to have stumbled over it;
but they certainly failed to see it, to estimate its value, and to
bring it into notice. Who was the first to see it, to understand
its value, to give it shape and form, to bring it into notice, and
urge its adoption, is a question to which we shall shortly give our
attention."
"At this point, we are constrained to say that we cannot yield
our assent to the argument that the combination of the different
parts or elements for attaining the object in view was so obvious
as to merit no title to invention. Now that it has succeeded, it
may seem very plain to anyone that he could have done it as well.
This is often the case with inventions of the greatest merit. It
may be laid down as a general rule, though perhaps not an
invariable one, that if a new combination and arrangement of known
elements produce a new and beneficial result never attained before,
it is evidence of invention. It was certainly a new and useful
result to make a loom produce fifty yards a day when it never
before had produced more than forty, and we think that the
combination of elements by which this was effected, even if these
elements were separately
Page 148 U. S. 562
known before, was invention sufficient to form the basis of a
patent."
Consolidated Valve Co. v. Crosby Valve Co.,
113 U. S. 157;
Magowan v. New York Belting Co., 141 U.
S. 332;
Barbed-Wire Patent, 143 U.
S. 275;
Gandy v. Main Belting Co., 143 U.
S. 587, are all to the same effect.
In the very recent case of
Topliff v. Topliff,
145 U. S. 156,
where there was a contest between two patents, with but a slight
difference between them, the Court said:
"Trifling as this deviation seems to be, it renders it possible
to adopt the Augur device to any side-spring wagon of ordinary
construction. While the question of patentable novelty in this
device is by no means free from doubt, we are inclined, in view of
the extensive use to which these springs have been put by
manufacturers of wagons, to resolve that doubt in favor of the
patentee, and sustain the patent."
We think therefore we are within the principle and reasoning of
these cases in reversing the decree of the court below dismissing
the bill, and in remanding the record, with directions to proceed
in the case in conformity with this opinion.
Reversed.
