Patent No. 959,008, Claims 1 and 3, to Elias H. Henderson, for
improvements in scaffold supporting means, exhibits no invention

The fact that a change in a composite instrumentality was
readily made may be evidence that the change was the result of mere
mechanical facility, as opposed to invention. P.

Advantages found in a patented device may count in favor of the
patentee though he did not discern them when he secured his patent;
but if the device is only an alteration of an earlier patented
device,
Page 254 U. S. 33
involving no invention, they redound to the benefit of the
earlier patentee though he also was unaware of them and did not
attribute them to his invention. P.

245 F. 747 reversed.
The case is stated in the opinion.
MR. JUSTICE McKENNA delivered the opinion of the Court.
Suit by petitioner against Chain Belt Company
et al.
for infringement of a patent considered in No. 22. The bill
contains the usual allegations, and prays for an accounting, for
damages, and injunctions, preliminary and final.
A copy of the opinion of the Circuit Court of Appeals for the
Eighth Circuit in the suit of the Scaffold Company against Egbert
Whitney, expressing the judgment of the court sustaining the
validity of the patent and adjudging Whitney to be an infringer of
it, is attached to the bill.
The answer denied invention, and sets forth a number of patents
as anticipations, among others, a patent to William Murray. A
dismissal of the suit was prayed.
A trial was had upon the issues thus made, which resulted in an
interlocutory decree awarding an injunction, adjudging
infringement, and an accounting.
The injunction decreed is as follows:
"That an injunction be issued under the seal of this Court unto
the said Chain Belt Company and the said Egbert Whitney
Page 254 U. S. 34
enjoining them, and each of them, their several agents,
officers, employees, and all persons in privity with them, and each
of them, from making or selling, or causing to be made or sold, the
machine known as 'Whitney Scaffold Hoist Machines' and 'Little
Wonder' machines, to be used in the combinations of Claims 1 and 3
of said U.S. patent No. 959,008, or from using or causing said
machines to be used in the combinations of said claims, or from
infringing upon said claims in any manner whatsoever."
The circuit court of appeals agreed with the district court that
the Henderson patent exhibited invention, expressing the view,
however, that, while its advance was slight, it was "not so wholly
wanting in invention or novelty as to justify a finding contrary to
the presumptive validity of the grant to him." The court fortified
its views by the decision of the Circuit Court of Appeals of the
Eighth Circuit in
New York Scaffolding Co. v. Whitney, 224
F. 452, citing, however, to the contrary, the decision of the
Circuit Court of Appeals of the Third Circuit, in
New York
Scaffolding Co. v. Liebel-Binney Construction Co., 243 F. 577,
the decision we have just affirmed.
Ante, 254 U. S. 24.
The court, however, decided that the decree was "erroneous in
finding infringement in the manufacture or sale or in any use of
the Little Wonder machine." The decree of the district court was
reversed with directions to enter a decree in accordance with the
views expressed.
The Henderson patent was made the basis of recovery in
New
York Scaffolding Co. v. Liebel-Binney Construction Co., No.
22, just decided, and there we estimated its inventive quality as
tested by the prior art, and as representative of that we took the
patent of William Murray, accepting it as an advance upon the prior
art.
We need only add to what was there said that our conclusion is
confirmed by Henderson's testimony, which
Page 254 U. S. 35
we insert in the margin somewhat fully, as it cannot be
adequately represented in condensation or by paraphrase. [
Footnote 1]
Page 254 U. S. 36
From his testimony, it is certain that his scaffold did not
cause him sleepless nights or laborious days. He was not
experienced in the art of which it is an example. It may be that
the conceptions of invention cannot be tested by such, or by
moments of time, and that originality
Page 254 U. S. 37
does not need the aid or delay of drudgery, but one is forced to
think that, where a change is readily made in any composite
instrumentality, the change is not the prompting or product of
invention. Indeed, it is a common experience in patent cases that
mere mechanical facility can alter or change the form in which
originality and merit expressed themselves, and assert for it the
claim of invention. This case is an example of such pretension. We
may repeat counsel's question, and ask: what did Henderson do that
Murray did not do? He made the U-frame which supported the hoisting
device of continuous metal, instead, as Murray did, of several
pieces riveted together, and in the stirrup which it formed he
rested the putlogs or beams, loosely making a hinged joint
connection between the stirrup and the hoisting machines, with a
resulting flexibility. This consequence and its advantage, if it
have such, [
Footnote 2] it is
admitted he did not discern, and naturally. His purpose was
evasion. To evasion he was prompted. Beyond what was necessary to
that, he exerted no vision or conception. He had had no experience
in the art, and what knowledge of the Murray scaffolding he had was
obtained by a thirty minutes' observation of it in operation. We
yield to the assertion of counsel that he cannot be deprived of an
advantage because he did not discern it, but the same concession
must be given to Murray. He was entitled to all of the benefit that
he claimed for his device, or that can be given to it by formal
changes.
It will be observed that the circuit court of appeals and the
district court disagreed in their views of the relation
Page 254 U. S. 38
of the Little Wonder machine to the Henderson device -- the
latter considering it an infringement; the former determining
otherwise, and to that extent reversing the decree of the district
court. Both courts, however, concurred in ascribing invention to
the Henderson device. In this, both courts erred, and the decree of
the district court is therefore reversed, and the case remanded to
that court, with directions to dismiss the bill of complaint, on
the ground that the Henderson patent is invalid, it exhibiting no
invention.
So ordered.

Footnote 1]
After stating the schools and colleges he had attended, and that
he was admitted to the bar in 1910, he testified as follows:
"Q. Will you state when you first acquired any knowledge of the
scaffolding business and how it came about?"
"A. The first time I had any occasion to consider scaffolding on
buildings was about in February, 1910 -- February, 1909. I was
having dinner with Mr. Merrill, then president of the Noel
Construction Company, and I explained to Mr. Merrill a certain gas
engine I was designing, attempting to get a patent at that time,
and Mr. Merrill, whom I had known while I was at the Academy at
Annapolis, put up to me a proposition of scaffolding on the city
hall, which the Noel Construction Company was then building in
Chicago, and explained to me the great expense of building up a
scaffold from the ground, and stated that it was much more
convenient and cheaper to scaffold by swinging the scaffold from an
overhead outrigger. He said there was such a scaffold in use and
being put up by a New York concern, but that the rental charged by
the New York concern was prohibitory of its use on the city hall,
and said, with my mechanical training, I ought to be able to devise
a means of swinging a scaffold, and instructed me to go ahead and
see what I could do."
"
* * * *"
"A. This was in February, 1909."
He further testified that Mr. Merrill called his attention to
devices that were then in use in Chicago at the Blackstone Hotel,
and that shortly after he went down to the hotel.
He further testified:
"A. On the north side of the building there was a scaffold
suspended by overhead outriggers, cables led down to a drum, the
cable passed over a little pulley wheel on the top cross member of
the scaffold down to a drum, and the drums were in pairs opposite
at right angles to the building. These drums were supported above a
U-frame which was held in place, bolted, with two angle irons, the
bolts passed through the U-frame, and then the planking were laid
along the scaffold on top of the angle irons which was bolted to
the U-frames, and the drums were operated by means of the ratchet
lever, to which the men put a pipe, making an extension, and pumped
it up and down."
"Q. Just how were the putlogs supported relative to the U-frame
concerning which you have testified?"
"A. The putlogs were bolted alongside of the U-frame and the
bolts passed through the U-frame."
"Q. Did you see the machines operate?"
"A. Yes; the men were laying brick along the scaffold; a couple
of laborers hoisted one end of the scaffold."
"Q. So you saw it raised during the time you were there?"
"A. Yes, sir."
"Q. At that time had you done any work on what later developed
into your patent in suit?"
"A. I had not."
And further:
"A. I didn't do anything further until about the middle of May.
Mr. Merrill called me up and asked me to come down to the office. I
went down, and he asked me if I had a scaffold ready for him, or
had any ideas. I told him, 'No; that I had not.' He said, 'I have
been depending upon you to design something, and I have got to have
something.' So he called in Mr. Peterson, the superintendent, took
me over to the city hall, and showed me the wall he wanted to
scaffold in the court there, and I then went over to Carpenter
& Co. and inspected some winches he had there, to see if it was
practicable to bolt the winches to wooden putlogs. And, owing to
the fact that Carpenter & Co. wanted more money than Merrill
could pay for scaffold, didn't make a deal with him. Then I went
home and made up the design for the scaffold that I subsequently
applied for a patent on, and took it down to Brown & Williams'
attorneys, and asked them if I could get a patent on it. They
thought I could. Mr. Merrill said he would have Parker & Carter
investigate if there would be no infringement on the winch, and
instead of bolting the widlass to the putlog, I found I could
utilize pieces of 2x10 around the building for putlogs and place
them in the U-frame, and would make the scaffolds easier to put
into the building and much simpler to dismantle -- to take
off."
"Q. Where did you get your knowledge of the U-frame being used
in this line of work?"
"A. I saw U-frames on the Blackstone Hotel. It was just an
ordinary stirrup."
[
Footnote 2]
There is a denial of advantage, and it was admitted at the
argument that rigidity of the putlog and frame was sometimes
resorted to. Counsel tried to minimize the necessity or practice by
saying that it was accomplished by a tenpenny nail. Manifestly it
was the effect and its necessity or advantage which were important,
not the means of their accomplishment, and the necessity or
advantage cannot be estimated by the size of the nail.
