Letters patent No. 228,186, issued June 1, 1880, to Maurice
Gandy, for an improved belt or band for driving machinery and an
improved mechanical process of manufacturing the same are valid,
and the novelty and utility of the invention protected by it are
not disturbed by the evidence in this case.
The "public use or sale" of an invention "for more than two
years prior to" the "application" for a patent for it, contemplated
by section 4886 of the Revised Statutes as a reason for not issuing
the patent or for its invalidation if issued, must be limited to a
use or sale in this country.
The Court stated the case as follows:
This was a bill in equity for the infringement of letters patent
No. 228,186, issued June 1, 1880, to Maurice Gandy, for an improved
belt or band for driving machinery and an improved mechanical
process of manufacturing the same. In his application, the patentee
stated that his invention consisted first of an improved cotton
belt; second, of an improved mechanical process for making cotton
belts.
"The belt consists first, of cotton canvas or duck composed of
warp stouter than the weft, both warp and weft being hard spun and
the canvas hard and tight woven; second, of cotton canvas or duck
thus made, folded and united by longitudinal rows of stitching, and
stitched under tension; third, or cotton canvas thus made, folded,
and stitched, saturated with linseed oil; fourth, of cotton canvas
thus made, folded, stitched, and saturated with linseed oil,
pressed and stretched until it is hard, even, and rigid, by which
the belt is rendered insensible to the atmospheric changes, and
nonelastic."
The machinery for manufacturing the belting is also set forth in
the specification, but the only claim alleged to be infringed in
this case was the second, which reads as follows:
"(2) The improved article of manufacture consisting of a hard,
even-surfaced, rigid, impervious, nonelastic belt, composed of
cotton canvas or duck having its warp thread larger than the weft,
both warp and weft being hard spun, the fabric tight-woven and
folded, stitched, and saturated with linseed oil."
The bill was in the ordinary form, and prayed for an injunction
and an accounting. The answer denied that the invention was new or
patentable, and also denied infringement. From a decree dismissing
the bill, 28 F. 570, the plaintiff appealed to this Court.

MR. JUSTICE BROWN, after stating the facts in the foregoing
language, delivered the opinion of the Court.
The bill in this case was dismissed by the court below upon the
ground either that the second claim of the patent was anticipated
by a provisional specification of Robert B. Jones, filed in the
office of the British Commissioner of Patents, July 31, 1878, or,
if Gandy made the invention before the date of Jones'
specification, that there had been a public use and sale of the
invention for more than two years prior to the application for the
patent in suit; in other words, that the same testimony which
showed priority of invention on the part of Gandy showed a public
use or sale by him of such invention more than two years prior to
his application.
On May 9, 1877, plaintiff Gandy, who is an alien and a subject
of her Britannic majesty, deposited at the office of the British
Commissioner of Patents a provisional specification upon which a
patent was subsequently issued for an improvement in machinery
belts. He stated the object of his invention to be the manufacture
of belts of cotton canvas that would not give out by stretching, or
be detrimentally affected by variations in the atmosphere, and at
the same time to be sufficiently pliable to allow of their running
around small pulleys without cracking. To accomplish this, he
Page 143 U. S. 589
manufactured his belts of cotton canvas or duck, "hard woven,"
put together either by hand or by folders, and formed into a belt
of the desired width and thickness, stitched with rows of
stitching, and then soaked or saturated in linseed oil. After the
saturation, the canvas is formed into a belt by folding and
stitching. After this it is passed through rolls to squeeze out the
superfluous oil, and it is then dried and painted, and lastly
stitched. The claim of this patent was
"for constructing belts or bands for driving machinery of cotton
canvas or duck, 'woven hard,' and stitched, and saturated or soaked
with oil, such as linseed oil or any combination thereof, as herein
described or set forth, or any modification thereof."
In 1883, this patent became the subject of litigation in the
Chancery Division of the High Court of Justice, and was held to be
invalid. In delivering the opinion of the court, Mr. Justice
Pearson expressed a serious doubt whether the patentee could claim
as a new invention a belt made of hard woven canvas when belts made
of other descriptions of canvas and saturated with oil were well
known and manufactured years before. He did not, however, decide
the case upon this point, but upon the ground that Gandy had not
taken out his patent for his real invention. "I think," he
said,
"he has described something in his patent which was not his
invention, and he has not described in his patent that which was
really his invention. . . . It appears that in the beginning of the
year 1877, Mr. Gandy was making various experiments in order to
perfect a belt which be was intending to patent, and, having made
those various experiments with different kinds of canvas, he at
last discovered that a canvas of a particular strength in the warp
was the best canvas that could be used for making these belts. . .
. But in the patent which he took out, there is not a single word
to indicate that the warp ought to be stouter than the weft; least
of all is there any indication that one particular strength in the
warp and one particular strength in the weft would make the best
canvas."
The learned judge held the patent to be bad because it did not
disclose the very best way of making the manufacture, remarking
that in a patent subsequently obtained by him, in 1879,
Page 143 U. S. 590
he did describe the mode in which the belt was to be made by
saying that the canvas in the warp was to be stouter than in the
weft.
On appeal to the Court of Appeals, the Master of the Rolls
expressed regret at the misfortune of the patentee in not
describing his discovery, "because," said he, "I think Mr. Gandy
did make a discovery." He held that the evidence showed that
Gandy's belts could only be made out of a particular class of
hard-woven canvas, and, as his claim was for the whole class, it
was too large. In short, he held the patent to be invalid because
it did not properly describe the invention, and closed his opinion
by again expressing his regret that, from the way in which the
specification had been drawn up, that which was a real and valuable
invention in itself did not seem to have been claimed. Lord
Justices Cotton and Lindley expressed practically the same opinion.
Gandy v. Reddaway, 2 Cutler's Rep. of Pat. Cases 49.
Prior to this decision, however, and on December, 1, 1877, Gandy
filed a substantial copy of his British specification with the
Commissioner of Patents, and made a similar claim for
"a belt or band for driving machinery, constructed of hard-woven
cotton canvas or duck, stitched, and saturated and interlarded with
oil, such as linseed oil, or any combination thereof, as herein
described or set forth."
A patent was refused, however, upon the ground that the alleged
invention was substantially anticipated by certain English patents
issued in 1858 and 1861.
Subsequently, and on September 10, 1879, he filed the present
application, and after some correspondence and amendments of his
original claims, this patent was issued. With his application he
also filed a specimen of his belt, which was the same in all
respects as the specimen filed with his prior application of
December 1, 1877, and was in fact the identical specimen.
(1) The defense to this patent is that on the 31st day of July,
1878, one Jones filed a provisional specification with the British
Commissioner of Patents for an improvement in belts which consisted
in increasing the strength of the warp or
Page 143 U. S. 591
longitudinal fibers or yarns over the weft or cross-fibers -- in
other words, precisely the same specification as that contained in
the second claim of the plaintiff's patent, or at least for the
only element of such claim which is novel. Plaintiff's reply to
this is that while Jones' application antedates his own in point of
time, his own invention was prior in point of fact, and in proof of
this he produces the three small pieces of belt attached to his
application of December 1, 1877, which the Commissioner of Patents
has certified were filed in the Patent Office by Gandy at that
date, and more than six months before the Jones specification was
filed in the British Patent Office. This canvas is really the only
one for which the patentee has sought to obtain a patent, although
his first application was refused because he neglected to describe
his real invention. Each of these belts is made of canvas, with
warp obviously larger than the weft, and containing every other
element of the second claim of the patent. In relation to this, Mr.
Gandy also testifies that he was acquainted with Jones, who was a
member of the firm of Garnock, Bibby & Co. of Liverpool, and
were customers of his. "They also," said he,
"made a stitched sail-cloth belting, and, when they found I had
taken a patent for a belting that was a success, they also applied
for a patent; seeing which in the papers, I asked Mr. Jones to tell
me what he was patenting, as he need have no hesitation in doing
so, seeing he had filed his provisional specification. He at once
told me that it was for a belt made with the warp stouter than the
weft. I told him if he would walk along to my factory I would show
him that I had been using for some time before his application a
cloth to make my belts in which the warp was stouter than the weft.
He went with me, and saw the cloth and the belts, and was satisfied
that such was the case, and hence went no further with his patent,
but abandoned the application."
The fact that no patent appears ever to have been issued upon
Jones' application makes the truth of this statement seem quite
probable. The canvas of which Gandy made use in England, it seems,
was manufactured by the Mt. Vernon Company of Baltimore, and in
further proof of the date of his invention,
Page 143 U. S. 592
he produced the testimony of the shipping clerk of that firm,
who swore that as early as 1876, the firm shipped to Gandy belting
canvas having the warp threads stouter than the weft, there being
six plies in the warp and only four in the weft. Mr. Gandy also
swears that since 1875, all the canvas ordered by him was made with
the warp stouter than the weft. As there is no testimony to
contradict this, it must be accepted as a fact in the case.
(2) The court below, however, found that, conceding that his
invention was made as early as 1876, antedating the filing of
Jones' specification by some two years, the same testimony also
proved that it had been in public use more than two years before
filing his application, and that under Rev.Stat. section 4886, the
patent was therefore void. All that the evidence upon this point
shows is that Gandy ordered all his canvas made by the Mt. Vernon
Company, and shipped to him at Liverpool. There is no direct
testimony to show whether this canvas was made up into belting or
when the belts were first publicly used or sold abroad; indeed
nothing to show that it was in public use or on sale before the
application for the patent in this suit was filed. Even if we were
authorized to presume that such canvas was manufactured into
belting and sold or used in England, there is not a particle of
testimony tending to show that it was publicly used or put on sale
in this country. Conceding that there was sufficient evidence of
the use of such belting in England, we think that this does not
vitiate the patent. Section 4886 declares that
"Any person who has invented or discovered any new and useful
art, machine, manufacture, or composition of matter, or any new and
useful improvement thereof, not known or used by others in this
country and not patented or described in any printed publication in
this or any foreign country before his invention or discovery
thereof, and
not in public use or on sale for more than two
years prior to his application, unless the same is proved to
have been abandoned, may, upon payment of the fees required by law,
and other due proceedings had, obtain a patent therefor."
It is true that the language of this section contains no
restriction as to the place or country wherein the public use
Page 143 U. S. 593
is made of the invention; but taken in connection with section
4887, providing that no person shall be debarred from receiving a
patent by reason of the invention's being first patented abroad
"unless the same has been introduced into public use in the United
States for more than two years prior to the application," we think
that the public use or sale contemplated by section 4886 must be
limited to a use or sale in this country. That this was the intent
of Congress is also manifest from section 4923, providing that
whenever it appears the patentee believed himself to be the
original and first inventor of the thing patented his patent shall
not be held void
"on account of the invention or discovery, or any part thereof,
having been known or used in a foreign country before his invention
or discovery thereof, if it had not been patented or described in a
printed publication."
So also in section 4920, providing what the defendant may plead
under the general issue in actions for infringement, there is
included the defense "that it had been in public use or on sale in
this country for more than two years before his application for a
patent, or had been abandoned to the public."
Taking all these provisions of the patent law together, we think
it was manifestly the intention of Congress that the right of the
patentee to his invention should not be denied by reason of the
fact that he had made use of it, or put it on sale abroad, more
than two years before the application, provided it were not so used
or sold in this country.
(3) The questions of novelty and utility may properly be
considered together. There is much testimony tending to show that
Gandy believed himself to be the inventor of a belting made of
hard-woven canvas, stitched, and saturated with oil, and that the
importance of having the warp stouter than the weft was not fully
appreciated by him, and hence was not made an element of the claim
of his original British patent. The testimony, however, shows that
the canvas or duck ordinarily used for sails is made with the weft
as stout, if not stouter, than the warp, and that such canvas was
found to be impracticable for belting on account of its liability
to stretch or to crack in passing around the smaller pulleys. His
first
Page 143 U. S. 594
belts, made of ordinary soft canvas, proved to be wholly
impracticable owing to their apparently endless capacity for
stretching. He next experimented with hard-spun and tight-woven
canvas specially manufactured for this purpose. This did not
stretch, but developed another fault of wrinkling and cracking when
running around pulleys. This he obviated by saturating it with
linseed oil, but found another objection in the unequal strain on
the several thicknesses when passing around the pulleys, which
tended to break the stitching and permitted the plies to separate.
He then conceived the idea that by decreasing the thickness of the
belt without diminishing its tensile strength, he would bring the
diameter of the exterior plies more nearly level with the inner
plies next the pulley, and thus more nearly equalize the strain on
all parts of the belt, increasing its effective strength, and
diminishing the tendency of the plies to separate or wrinkle. It is
obvious even to a nonexpert that if the belting be made very thick,
there is a much greater strain upon the exterior plies when passing
around a small pulley than upon the inner plies, and that the
effect must be both to unduly strain the exterior plies, rendering
them liable to break, and to wrinkle the inner ones, subjecting
them to the danger of cracking, and that the ideal belting would be
made as thin as would be consistent with the requisite strength and
inflexibility. In view of the fact that previous attempts of which
there appear to have been several, to make a practical canvas belt,
had been failures, and that Gandy had been experimenting with the
subject for several years before he discovered that a change was
necessary in the structure of the canvas itself, we do not think
his improvement is a change in degree only, or such a one as would
have occurred to an ordinary mechanic, and our opinion is that it
does involve an exercise of the inventive faculty. The change is
such as would only have occurred to one familiar not alone with the
impossibility of making a practical belt out of the ordinary
canvas, but to one who had bestowed considerable thought upon the
method of overcoming the difficulty. While some of the testimony
would seem to indicate that there is no great advantage in this
method of
Page 143 U. S. 595
construction, we think the fact that it has been largely adopted
by manufacturers, and that all the modern improved belting ordered
or made by Gandy and in general use both in this country and in
Europe is made in this way is, for the purposes of this case,
sufficient evidence of its utility.
Magowan v. Packing
Co., 141 U. S. 332.
4. We have no doubt upon the subject of infringement. While, as
claimed by the defendant Plummer, there may be as many plies or
individual threads in the weft of his canvas as in the warp, the
most casual observer of the relative strength of the warp and the
weft cannot fail to notice that the former is much thicker and
stouter than the latter -- in fact, that the Gandy belting and the
defendants' in this particular are identical. The defendant
Plummer, having adopted Gandy's idea of making warp stouter than
his weft, is not in a favorable position to claim that it is
useless. Indeed, Plummer appears to have been formerly in business
with Gandy, and was sent by him to America in 1879 to confer with
his solicitor in reference to his pending application for a patent.
Gandy subsequently decided to start the manufacture of belting in
America and to give Plummer employment, and for that purpose took
him into his factory in Liverpool so as to give him an insight into
the business. In 1880, he came to America, was met by Plummer,
leased a building for a factory, and took him into his employ.
Plummer seems, however, to have failed to give satisfaction, and
Gandy subsequently dismissed him from his service, whereupon
Plummer proceeded to organize a company upon his own account for
the manufacture of the infringing belting. In pursuance of this
intention, he states himself that he came to Washington, examined
the Gandy patents, and took legal advice with regard to making a
belt which would not infringe them. He also suggested to plaintiff
the danger of his marking an unpatented article with words
importing that it is patented, and called his attention to
Rev.Stat. sec. 4901 making this a penal offense.
The language of Mr. Justice Woods in delivering the opinion of
this Court in
Lehnbeuter v. Holthaus, 105 U. S.
94,
105 U. S. 96, is
equally pertinent to this branch of the case:
"The patent is
Page 143 U. S. 596
prima facie evidence both of novelty and utility, and
neither of these presumptions has been rebutted by the evidence. On
the contrary, they are strengthened. No anticipation of the design
is shown, although the attempt has been made to prove anticipation.
The fact that it has been infringed by defendants is sufficient to
establish its utility at least as against them."
The decree of the circuit court is therefore
Reversed and the case remanded with directions to enter an
interlocutory decree for the plaintiff and for further proceedings
in conformity with this opinion.
