249 F. 211 affirmed.
The case is stated in the opinion.
MR. JUSTICE McKENNA delivered the opinion of the Court.
Suit brought in the district court of the United States for the
District of Indiana to restrain the infringement of a patent for a
retaining wall, which, to quote petitioner, is "a wall to prevent
the material of an embankment or cut from sliding."
After issue joined and proofs submitted, the district court
(Anderson, J.) entered a decree dismissing the bill for want of
equity. The decree was affirmed by the circuit court of appeals, to
review which action this writ of certiorari was granted.
The bill in the case is in the conventional form, and alleges
invention, the issue of a patent numbered 705,732, and infringement
by respondent. The prayer is for treble damages, an injunction, and
accounting.
The answer of respondent is a serial denial of the allegations
of the bill, and avers anticipation of petitioner's device by prior
patents and publications in this and other countries.
This summary of the issues is enough for our purpose, and we
need only add preliminarily to their discussion that Bone's device
has the sanction of a patent and a decision sustaining it by the
District Court for the Northern District of Ohio and the Circuit
Court of Appeals for the
Page 251 U. S. 136
Sixth Circuit. The difference of decision in that circuit and
the Seventh Circuit is an important consideration, and must be
accounted for, which is best done by a display of the patent and
the case.
First, as to the patent: it describes the invention as being one
that
"relates to improvements in retaining walls for abutments to
bridges, . . . and such places as it is desired to retain earth or
other matter permanently in place with its face at an angle nearer
vertical than it would naturally repose when exposed to the action
of the elements or gravity,"
and
"consists principally of introducing into masonry of concrete,
stone, or brick a framework of steel or iron in such way that the
whole wall is so much strengthened thereby that the volume of the
masonry may be greatly reduced, and yet the height, base, and
strength against overturning, bulging, or settling will still be
ample."
The following figure represents a cross-sectional view of the
device -- A representing the masonry, B the material retained, and
B1 the earth on which the wall rests. The metal parts within A are
indicated by the smaller letters.

Page 251 U. S. 137
The patent does not insist upon that form of the masonry in all
particulars. The base of the wall may be, it is said, "varied to
suit the circumstances;" it (the base) may extend to the rear,
rather than the front
"with proper proportions of metal . . . the form shown in the
drawings being what might be called an inverted T, while those
suggested would be in the form of an L or reversed L."
The utility of the wall of these shapes is represented to be
that it is
"not so liable to be overturned from the pressure of material
behind it as would be a wall of the same height and area of section
but having a rectangular, trapezoidal, or triangular shaped
section,"
the latter shapes requiring more masonry. And it is said that
the patented wall, "having more base and less weight" than such
other shapes, "will rest more securely on a soft or yielding
foundation, the weight of the material resting on the heel" causing
the latter "to press on the earth below, and thus cause friction to
prevent the whole wall from sliding outward." This is the especial
effect of the patent, achieved by the wall of the shape described,
and distinguishes it, is the contention, from the retaining walls
of the prior art.
The patentee admits, however, that retaining walls had been
"constructed of concrete and steel, but none" to his "knowledge"
"had been supported on their own base as" his, nor had "any of them
entirely enclosed the steel within the concrete," nor had "any of
them used the weight of the material retained as a force to retain
itself."
Such, then, is the wall and the utility attributed to it. The
combinations which may be made with it are set forth in 17 claims,
of which 1, 3, 5, 16, and 17 are involved in the present action.
Counsel for petitioner considers, however, that 1 and 17 are so far
illustrative that the others need not be given. They are as
follows:
"1. The combination with a retaining wall having a
Page 251 U. S. 138
heel, of a metal structure embedded vertically in said wall and
obliquely in said heel, so that the weight of the retained material
upon the heel of the metal structure will operate to retain the
wall in vertical position."
"17. The combination with a retaining wall having an inclined
heel and a toe at opposite sides thereof, of a metal structure
embedded within said wall and heel, said structure consisting of
upright bents at the back part of the vertical wall and continuing
down along the upper part of the heel of said wall to the back part
thereof, whereby, by reason of the toe and the heel, the weight of
the retained material upon the heel of the metal structure will
operate to maintain the wall in a vertical position."
So much for the device of the patent. How far was it new, or how
far was it anticipated?
Bone's idea was conceived in 1898, and his patent issued in
1902, upon an application made in 1899, but, according to his
counsel, the value of the invention was not recognized "until after
the lapse of several years," when he, Bone, brought a suit against
the City of Akron, Ohio, in the District Court for the Northern
District of Ohio, in vindication of the patent and in reparation
for its infringement. He was given a decree which was affirmed by
the Circuit Court of Appeals for the Sixth Circuit. 221 F. 944.
The district court (Judge Day) gave a clear exposition of the
patent, the relation of its metal parts [
Footnote 1] to the masonry
Page 251 U. S. 139
parts and their cooperating functions, and adjudged the patent
valid and the wall of the City of Akron an infringement of it.
The circuit court of appeals affirmed the decree. The court said
that the record disclosed nothing which anticipated "the
substantial thought of the patent." If it had done so, or, to quote
the exact language of the court:
"If the prior art had shown a structure intended for a retaining
wall, and having a heel such that the weight of the earth thereon
would tend to keep the wall erect, it might be difficult to find
invention in merely adding the form of reinforcement most suitable
to create the desired tensile strength; but we find no such earlier
structures. [
Footnote 2] "
Page 251 U. S. 140
On application for rehearing, the court refused to direct the
district court to open the case to permit the defendant to put in
proof regarding a German publication of 1894.
Those decisions confronted the district court in the present
suit and fortified the pretensions of the patent. They were
attacked, however, as having been pronounced upon a different
record, and this conclusion was accepted by the district court. The
latter court found from the new evidence the existence of a
structure upon the nonexistence of which the Circuit Court of
Appeals for the Sixth Circuit based its conclusion. The district
court said that Bone was not the first to do the things he asserted
he was the first to do, and that, whatever the record in the Sixth
Circuit might have shown, so far as the record before the court
"was concerned, the absolute converse of that proposition" had
"been demonstrated."
The court therefore as we have said, dismissed the bill for want
of equity.
The decree was affirmed by the circuit court of appeals; indeed,
the reasoning of the district court was approved after painstaking
consideration of the patent and an estimate of the anticipatory
defenses, none of which the court said was introduced in the
Akron case, "otherwise a different conclusion would have
been reached," adducing the opinion of the court. 249 F. 214. This
being so, and there is no doubt it is so, the present case is
relieved of the authority or persuasion of the
Akron case,
and it becomes necessary to consider the prior art and decide the
extent and effect of its anticipation.
We have given a cross-section of the device of the
Page 251 U. S. 141
patent, showing its shape and strengthening "metallic members,"
and the patent informs of their cooperative function. We reproduce
the device and set by its side the Marion County wall for
comparison.

If we may assign novelty to the Bone wall and consider it a
broad advance upon the prior art (the extent of its advance, if
any, we shall consider later), we may assign infringement of it by
the Marion County wall. To an examination of the prior art we are
therefore brought.
It would be difficult to add anything to the consideration and
comment of the court of appeals. The court cited in support of its
judgment a patent issued to Francois Coignet in 1869, and one
issued to Stowell & Cunningham in 1899 upon an application made
in 1897, and to articles written by P. Planat which appeared in
1894 and 1896 in a scientific magazine called "La Construction
Moderne," published in Paris; also a publication which appeared in
Germany in 1894 concerning a wall which is given the name of
Bauzeitung wall. The article recites that a "utility model patent"
had been granted, consisting "of a vertical and a horizontal
member."
The Coignet patent is somewhat indefinite. It relates, according
to its declaration, to "monolithic structures, or articles made of
artificial stone paste" into which irregular shaped irons are
introduced to be
"arranged in such a
Page 251 U. S. 142
manner as to interlace each other, so that, by the combination
of this metallic skeleton and of agglomerated artificial stone
paste, the thickness of the walls or size of the articles may be
considerably reduced and yet great strength be attained."
It will be observed that there is nothing explicit of how "stone
paste" and the "irregular shaped irons" operate or cooperate, aside
from their cohesion or interlacing. Their arrangement is not
definite as the "metallic members" in the Bone patent are, so that
there might be, as in that patent, reinforcing metal in the heel of
the wall acting with its upright portion serving the function, to
quote Judge Day,
"of a cantilever beam whereby the weight of the material
pressing upon the heel is transferred to the upright of the wall
and operates to retain the wall in a vertical position."
If there was any prophecy (to borrow counsel's word) in it, the
world was slow to discern it, and we are not disposed to give much
anticipating effect to it, a view in which we have confirmation in
the disclaimer of Bone, he conceding he was not the first to
discover the art of reinforcing concrete.
The Planat publications are more explicit. We there see a
relation between the metallic and masonry parts of a wall and their
cooperation to produce strength in the wall and resistance to the
pressure of and bulging from the stress of earth behind it. Both
articles, the court of appeals said, "deal with retaining walls of
reinforced concrete of the cantilever type," and quoted from the
article of 1896 as follows:
"These computations suppose that one has effectively realized
the fixing of the vertical wall to the horizontal slab at their
junction. This fixing requires special precautions. The bars at the
point of junction exert a pulling force which tends to pull them
out of the concrete. . . . But here we have only a half beam on a
cantilever span. It is necessary that the extremities of the bars
in the
Page 251 U. S. 143
region of fixation should be held in a sufficient mass of
concrete or maintained by some other means."
"One is able to reduce these projections in a very large measure
if one takes care to bind together the vertical bars and the
horizontal bars at their point of intersection. In this way, the
pull of the bar is carried not only on its prolongation, arranged
for anchorage, but also on the bar which is perpendicular to it,
and whose great length permits it to offer a large resistance to
the force tending to pull it out transversely."
The court did not enlarge upon other examples of the prior art,
nor do we think that it is necessary to do so. The court, however,
referred to a publication in Bauzeitung and the patent to Stowell
& Cunningham. The former is too technical to quote, and the
latter has not the simplicity of the Bone device, but both
publication and patent represent structures that resist a tendency
to tilting or bulging from the pressure of the earth in their
rears. The Bauzeitung article did this by a wall which consisted of
a "vertical and a horizontal member" which were "rigidly connected
with each other," and
"the ratios so chosen that the resultant of the earth thrust
passes through the horizontal part or through the foundation
respectively, so that there exists no longer any tendency to
tilting so long as the two parts continue to be firmly connected
with each other."
It is further said: "To increase the stability, the horizontal
part is furthermore connected at its rear end by means of anchors
with the underground." It will be observed, therefore, that there
are no metallic reinforcing members. It is the shape of the wall --
one having a base extending to the rear in the form of an L, the
exact antecedent of one of the shapes described by Bone as having
advantage over other shapes. And there was also the suggestion of
the value of a firm connection between the "vertical and horizontal
member." In other words, the publication showed a retaining
Page 251 U. S. 144
wall having a heel such that the weight of the earth thereon
would tend to keep the wall erect, an effect and operation that
Bone declares in his patent no wall had attained prior to his
invention. And that effect and operation the Circuit Court of
Appeals for the Sixth Circuit considered the essence of the Bone
patent, and the court said that "[i]t might be difficult to find
invention in merely adding the form of reinforcement most suitable
to create the desired tensile strength."
The Stowell & Cunningham structure is, as we have said,
somewhat complex in its mechanical parts. But these are but
details; the physical laws that they are to avail of are explained
so that "the volume of masonry" of retaining walls may be reduced,
yet retain their strength by the use of metallic
reinforcements.
Counsel attacks the sufficiency of the asserted anticipations,
especially the publications, and in effect says that whatever
conceptions lurked in them conveyed no suggestion of a "concrete
entity," to use counsel's words, to execute them, and laments that
Bone should be robbed of the credit and reward of adding to the
world's useful instrumentalities which, but for him, would have
remained in theories and the "dust from which respondent recovered
them."
To execute theories by adequate instrumentalities may indeed be
invention, but an answer to petitioner's contention we have given
by our comment on the Bauzeitung and Planat publications and the
fullness of their expositions. Bone may have been ignorant of them,
and his device may not have been their suggestion. They seem to
have been unknown to American engineers, not even the interest of
the controversy in the Sixth Circuit having developed their
existence. From this local ignorance, nothing can be deduced
favorable to the patent. Its device having been described in
printed publications, although in foreign countries, patentable
novelty or originality cannot be asserted for it. Section 4886,
Rev.Stats.; 29 Stat. 692, c. 391.
Page 251 U. S. 145
Such is the provision of the law, and we cannot relax it in
indulgence to what may seem the individual's merit.
The circuit court of appeals, to show the progress of the prior
art, made use of the illustrations [
Footnote 3] of the patents and publications that preceded
Bone's, and we also avail ourselves of the same to show that Bone's
patent was a step, not a leap, in that progress, and that the only
originality that can be accorded it is in its special form, and
there can be no infringement except by a copy of that form or a
colorable imitation of it. We do not think the Marion county wall
is subject to either accusation, and the decree of the circuit
court of appeals is
Affirmed.
MR. JUSTICE DAY took no part in the consideration or
decision.
[
Footnote 1]
The following is an extract from Judge Day's opinion:
"The reinforcing members [metallic members] are placed near the
back face of the wall and heel and near the lower face of the toe.
The oblique reinforcing bars in the heel, acting in conjunction
with the uprights, serve the function of a cantilever beam whereby
the weight of the material pressing upon the heel is transferred to
the upright portion of the wall and operates to retain the wall in
a vertical position. . . ."
"Considering the claims of the patent and the testimony, I am of
the opinion that Bone, the patentee, was the first to reinforce the
retaining wall, or similar wall of concrete or masonry in such a
manner that the weight of the retained material would be utilized
to impart through the reinforcing members tensile resistance to the
stern or vertical part of the wall, thereby fortifying this part of
the wall against breaking strains."
"This was an advancement in the art, and possessed novelty and
the structure of the defendant city infringed this patent."
"While many of the features of concrete structures were old, yet
this combination, as outlined and described in this Bone
application for a patent, was new. It is also in evidence that
there has been a large sale and general acquiescence in the Bone
patent."
[
Footnote 2]
The following is an extract from the opinion of the circuit
court of appeals:
"The record discloses nothing anticipating the substantial
thought of the patent. Masonry or concrete retaining walls were
deep and heavy, and maintained by gravity in their resistance
against a horizontal stress. There was no occasion for
reinforcement. Sustaining walls had been built of concrete with
vertical reinforcement, but they were maintained against side
strain by cross-ties or beams, without which they might tip over.
If the prior art had shown a structure intended for a retaining
wall, and having a heel such that the weight of the earth thereon
would tend to keep the wall erect, it might be difficult to find
invention in merely adding the form of reinforcement most suitable
to create the desired tensile strength; but we find no such earlier
structures. Those which have that shape are sustaining walls only,
and were so obviously unfit for use as retaining walls that no one
seems to have seen the utility for that purpose, of which the form,
when properly adapted and strengthened, was capable. There is also
a prior wall, wholly of metal, fairly disclosing a unitary heel
adapted to hold the wall erect; but to see that this could become
merely a skeleton imbedded in concrete may well have required, in
1898, more than ordinary vision. Upon the whole, we think invention
was involved, and the claims are valid."
