a method for repairing runs in knitted fabrics, such as stockings,

repairing device or needle having a hook and a pivoted latch, held
"laterally out of alignment with the run," is invalid for want of
proper disclosure and for lack of invention. Pp.

Certiorari, 294 U.S. 702, to review the affirmance of a decree
of the District Court,
60 F.2d
1009, dismissing the bill in a suit of the Stelos Company for
alleged infringement of its patent. Both sides sought and obtained
the writ.
MR. JUSTICE ROBERTS delivered the opinion of the Court.
This cause presents issues as to validity and infringement of
claim 23 of the Stephens reissue patent, No. 16,360, for "an
improvement in needles and its method of use." The Stelos Company,
owner of the patent, sued Hosiery Motor-Mend Corporation and others
for infringement. The District Court adjudged the claim invalid by
reason of failure to make proper disclosure of the alleged
invention, and anticipation, and also thought that, if the claim
were sustained, the defendants did not infringe, and dismissed the
bill. [
Footnote 1] The Circuit
Court of Appeals held the prior art required so narrow a
construction of the claim as to exclude the method charged as an
infringement and affirmed the decree. [
Footnote 2] We granted certiorari [
Footnote 3] to resolve a conflict with a decision of
the Court of Appeals of the District of Columbia. [
Footnote 4] In support of
Page 295 U. S. 239
the judgment, the defendants might have urged the point as to
invalidity, decided against them in the Circuit Court of Appeals,
without applying for a cross-writ of certiorari. [
Footnote 5] Out of excess of caution,
however, they prayed for the writ. Since both writs would run to
but one judgment and bring up the same record, we granted the
prayer in No. 653. [

To knit is to form a fabric by the interlacing of a single yarn
or thread in a series of connected loops. In knitted articles, of
which a silk stocking is an example, a break in the thread anywhere
in the fabric will cause a number of loops to pull out, leaving in
their place parallel threads. The consequent defect is called a
ladder, or a run. The only possible method of repair consists in
picking up the thread at the end of the run and reknitting by
reforming the loops throughout the ladder, fastening the thread
upon the completion of the operation. It has long been known that
this could be accomplished by the use of a needle having a hook at
the end resembling an ordinary crochet needle, but the task
involved difficulties, and the result was often unsatisfactory.
Stephens' patent is for an improved latch needle for this work,
and for a method of executing the repair. Twenty-two claims for the
needle are not in issue. Claim 23, which covers the method, is the
basis of the suit. The method is stated in the patent to
consist:
"in
stretching the fabric over a
suitable
holder,"
"inserting a repairing device having a hook and
pivoted
latch through a loop formed in the run or raveling,"
"continuing this movement on through the fabric
while
holding the device laterally out of alignment with the run or
raveling until the loop has slid back over the end of the
latch and beneath the latter, "
Page 295 U. S. 240
"then reversing the movement of the device through the
loop,"
"catching the next forward thread in the hook while the loop is
being pulled over the latch causing the latch to close over the
thread, and the loop to be cast off over the end of the device, the
thread caught in the hook thereupon forming a new loop, taking the
place of the first-described loop,"
"then reinserting the device into the fabric as before, and
repeating the operating until the run or raveling has been
repaired,"
"and finally fastening the thread."
In the commercial method practiced by the owner of the patent
and its licensees, the fabric is stretched over the top of a china
or porcelain egg cup held in the left hand. The degree of
stretching can in this way be adjusted for the first step in the
process, and increased or relaxed as the work progresses. The
needle is held in the right hand at an angle to the plane of the
fabric and worked back and forth through the material. Whether the
needle is also inclined laterally out of the line of the run is
disputed. The patentee says this is unnecessary, and is not in fact
practiced. The defendants disagree, and contend that a pivoted
latch needle will not otherwise perform its function. The alleged
infringers employ a metal holder shaped like an egg cup and a
sliding latch needle, which they punch through the material and
draw back at approximately a right angle to the fabric.
Stephens, while in Mexico in 1921 or 1922, noticed a Mrs. De
Marr repairing runs by stretching stockings over her finger and
reforming the loops with a latch needle. On her behalf, he
forwarded to a patent attorney a description and specification in
his own handwriting, and an application for patent was filed by
Mrs. De Marr. A half interest was assigned to Stephens. Certain
prior patents
Page 295 U. S. 241
were cited against the claims, and the application was
abandoned. Shortly thereafter, Stephens filed in his own name an
application for patent of an improved pivoted latch needle and for
an improved method of repairing runs. The method claim called for
the use of a pivoted latch needle having all the features of that
described in the application, and was accordingly rejected,
inter alia, because it was not a method claim, since it
required Stephens' specific construction of the needle. The
applicant redrafted the claim to call merely for a pivoted latch
needle, and added the element that the needle should be held
laterally out of alignment with the run. We think the method claim
is bad for want of proper disclosure, and as lacking invention.
1. The first step is described as "stretching the fabric over a
suitable holder." It is now said that an egg cup or something of
like construction is the only suitable holder, because no other
device affords a rest for the operator's hand and permits
continuous stretching in varying degree during the repair
operation. The patent drawings show no holder of any sort. The
specifications merely say:
"In other methods, the fabric is stretched over the fingertip,
making it difficult to insert the hook beneath the thread. This
objection is obviated in the present invention by stretching the
fabric over a porcelain dish, allowing sufficient depth for the
free use of the needle."
Obviously the phrase "a porcelain dish" is not descriptive of an
egg cup. There is nowhere any reference to the control of the
degree of stretching which is now said to be essential and to be
afforded only by such a holder. The patentee testified on the trial
that he tried and discarded many types of holder, until he hit upon
this one. If so, why did he not describe or claim it? He did so in
an application for patent filed much later. He is upon the horns of
a dilemma -- he either discovered this form of holder and its
virtues prior to the application for this
Page 295 U. S. 242
patent or he found it later. If the first supposition be
correct, his application violated R.S. § 4888; [
Footnote 7] if the second, his patent does
not cover the egg cup holder.
Nowhere does the claim or the specification disclose the element
that the fabric must not be tautly stretched over the holder, or
that it must be so held that the tension can be varied. It is said
that the use of the present participle "stretching," rather than
the past participle "stretched," makes the matter clear, but
scrutiny of both claim and specification discloses no teaching as
to the stretching of the fabric, or any regulation of the tension,
or that it may not be tightly stretched over the holder and secured
in that condition prior to commencing the repair. The specification
of a "suitable" holder certainly covers none of these alleged
essentials. These omissions emphasize the failure to make the fair
disclosure demanded by R.S. § 4885.
The patentee says that, in the old finger method, the needle
necessarily was held nearly in the plane of the fabric, whereas in
his method it is approximately at a right angle thereto, and
operated by a punching motion. The description of the operation in
the patent is almost identical with that of Mrs. De Marr's
abandoned application, drawn in Stephens' own hand, which was for
the finger, as contrasted with the punch, method, and, so far as
the angle at which the needle is to be held is very similar to
Pogson's disclosure in 1921, which Stephens says does not describe
the punch method. When we come to the claim, we find the phrase
"while holding the device laterally out of alignment with the run."
This, we are told, is novel, and means that the needle is not to be
used in or nearly parallel with the plane of the Fabric,
Page 295 U. S. 243
but at an angle thereto. "Laterally out of alignment to the run"
is not equivalent to "at an angle to the plane of the fabric." That
the applicant did not intend it to be so understood is shown by his
repeated use of the word "laterally," in the specifications, as the
equivalent of off to one side, and by this sentence: "The clearance
afforded . . . makes it possible to hold the needle down closer to
the fabric. . . ." There is no disclosure of any up and down punch
system such as the defendants use.
2. Pivoted latch needles are old in the art. Holders which have
an opening to give room for the insertion of a needle such as that
of an egg cup are old for use in darning. The method of reforming
loops in knitted goods with pivoted latch needles was known prior
to the application for this patent. The combination of the use of
the egg cup type holder and the pivoted latch needle did not
entitle Stephens to a patent, and the addition of the element that
the needle should be held at an angle to the plane of the fabric,
if that is in fact what the claim means, is insufficient to raise
the method to the dignity of invention.
Decree modified and, as modified, affirmed.
