ON APPEAL FROM THE EXCHEQUER COURT OF CANADA
(suit No. 13674)
Patent—Validity—Prior disclosure
The judgment of the Exchequer Court, [1932]
Ex. C.R. 127, dismissing the plaintiff’s action for damages for alleged
infringement of a patent relating to a locking device for separable slide
fasteners, was affirmed, on the ground that the plaintiff’s patent was invalid,
all its essential points having been already brought out in a disclosure
patented in France more than two years prior to the application in Canada for
the patent in question.
APPEAL by the plaintiff from the judgment of
the Exchequer Court of Canada
dismissing its action, which was brought for a declaration that the defendants
had infringed certain letters patent and that the said letters patent were
good, valid and subsisting letters patent, an injunction, damages, etc. The
material facts of the case, for the purposes of the present judgment, are
sufficiently stated in the judgment now reported. The appeal was dismissed with
costs.

respondents.
The judgment of the court was delivered by
Rinfret, J.—This action was brought by the appellant against the respondents
for a declaration that a certain patent (No. 288925) granted to the appellant
was good, valid and subsisting and that the respondents had infringed the
patent. The Exchequer Court of Canada dismissed the action and this is an appeal from the judgment of
that court.
The patent relates to a locking device for
separable slide fasteners, that is to say: fasteners consisting of two rows of
co-operating elements (locking members) which are caused to engage with one
another by the passage of a slider along the rows and are disengaged by the
movement of the slider in the opposite direction.
The appellant’s invention is described as
follows in the specification of the patent:
According to this invention, a slider pull
is provided adjacent its pivot with one or more fingers or lugs shaped to
extend through a recess in the slider wing for direct engagement between
locking members on one stringer or the lug may indirectly co-operate with said
members through the aid of some other part of the slider. Preferably these lugs
are spaced longitudinally and laterally to be engaged between locking members
on each stringer.
It is claimed that the finger or lug automatically
moves by gravity into position, through the recess, between two of the
co-operating fastener elements and thus provides locking means whereby the
slider is retained against movement in either direction on the stringer. A
feature is that by means of this device the movement of the slider may be
prevented at any point along the stringer.
The patent was applied for on the 26th of
January, 1928, and was granted on the 16th of April, 1929.
The infringing article is also a locking device
for separable slide fasteners; and, in the judgment appealed from, it is
described as follows:
* * * the pull or tab has two small lugs on
its upper edge, bent at right angles to the face of the pull, one of which is
longer than the other,
[Page 379]
the longer one being intended to go between
the units, the other being intended simply as a support. The pull is not
pivoted on the front wing of the slider but travels on a longitudinal slide the
full length of the slider, and falls below the slider where the longer lug enters
between the units, thus preventing any sliding of the fasteners. There is no hok extending through any portion of the wing
of the slider. There are two slight recesses, not holes, at the bottom of the
slider, on either side of the longitudinal slide, against which the lugs or
fingers rest when in a locking position; it is really at the end of the front
wing of the slider that the lug enters between the units.
We agree with the appellant that, for the
purposes of the case, no distinction ought to be made between a travelling and
a fixed pull. The invention relates to a mode of locking a slider, not to a
mode of attaching the pull; and whether the pull has a fixed or travelling
pivot is irrelevant, since it operates in the same way and the substitution of
the one for the other has no effect upon the operation of the lock.
It is also immaterial whether the finger or lug
reaches the fastener elements through a hole or through a recess; both recess
and hole fulfill exactly identical functions. At best, one would be the
mechanical equivalent for the other. The appellant’s patent shows various
embodiments of the invention. The specification uses the word “recess”; but the
claims may be construed to cover indifferently a hole or a recess.
The respondent Prentice commenced to manufacture
his slider lock and put it on the market in the United
States in the Fall of 1925. It was shown through
Canada early in 1926; but the first definite order for the article in this
country was in October, 1926.
The respondents pleaded, amongst other things,
that the appellant’s patent was invalid because the invention was patented or
described in printed publications more than two years before the application
for the patent; and, at the trial, reference was made to the fastener of M.
Gabriel Fontaine, a patent for which was applied for in France, on the 14th of
November, 1923, and granted on the 5th of March, 1924. A copy of the patent was
produced, as also an enlarged model of the slider used in connection with that
fastener. As described in the patent, in the Fontaine device, the pull of the
slider is provided with two spaced lugs adjacent its pivot. When the stringers
are drawn up through the channels of the slider, as soon as the pull is
[Page 380]
released; it comes down by force of gravity and
the lugs are pressed against the fastener elements, immediately above the
conical edges of the slider, where the fasteners are in engagement, thus
offsetting the fasteners, retaining them against movement and preventing the
slider from working in any direction.
The Fontaine fastener was primarily intended for
use on footwear. But we can conceive of no reason why it could not equally be
used on any number of other articles where fasteners are employed; and the
point is that, in the Fontaine patent, the locking device disclosed is
substantially similar, is designed for exactly the same purpose and the
disclosure gives the same knowledge as the appellant’s patent. Fontaine, in his
patent, begins by describing the invention, first in a general way, and then by
way of reference to each of the drawings. On the drawings, the slider is marked
as number 7, comprising the coupling member 8 and the pull or tab 9. The
fastener elements are indicated by No. 6 and the lugs on the pull by Nos. 10
and 11. Other numbers are used to indicate other parts of the device; but we
think that if the above numbers are borne in mind, it will be easy to
understand the following quotation from the patent:
Le rapprochement des bandes en vue de leur
emboîtement est obtenu par une pièce 7 formant coulisse. Cette pièce particulière comporte deux parties 8, 9 dont l’une peut pivoter autour de l’autre.
La partie 8 qui est creuse,
aplatie et cylindro-conique coiffe les extrémités opposées des lamelles 6 qui font légèrement saillie à cet effet de
sorte que lorsqu’on tire la pièce 7 dans un sens d’une façon quelconque les lamelles passant successivement
par la partie conique sont rapprochées lorsqu’elles arrivent dans la partie cylindrique et s’emboîtent. La partie 9 porte deux ergots 10,
11 et vient sé rabattre, après fermeture de la chaussure,
sur la pièce 8, sa fenêtre 12 recevant la saillie 13
de la pièce 8. Les ergots 10, 11 viennent
alors obturer les sorties 14, 15 de
la partie conique de la pièce 8 en
coinçant les lamelles 6 s’y
trouvant à ce moment et empêchant ainsi le décrochage des bandes, tant que la
pièce 9 reste appliquée sur la
pièce 8.
Pour défaire la chaussure il suffit de relever
la pièce 9, de tirer les
extrémités des bandes en les écartant et le décrochage a lieu, la pièce 8 coulissant le long des bandes dans le sens
inverse de l’accrochage.
Il reste d’ailleurs entendu que l’invention n’est
pas strictement limitée aux dispositions décrites qui peuvent varier de forme,
de dimensions, de matière constitutive, etc.
“Résumé.
Fermeture pour chaussures remplaçant le lacet
et autres caractérisée en ce que les bords du soulier à réunir portent des
bandes composées de lamelles métalliques distinctes dont l’extrémité libre
forme saillie d’un
[Page 381]
côté et un creux de l’autre pour permettre
leur emboîtement lorsque les bords du soulier sont rapprochés.
Ce rapprochement est obtenu par une pièce
constituée en deux parties dont l’une creuse, plate et cylindro-conique coiffe
les saillies opposées des lamelles et dont l’autre qui porte deux ergots vient
se rabattre sur la première pour coincer les lamelles et empêcher le mouvement
des bandes.
It will thus be seen that all the essential
points in the appellant’s patent were already brought out in Fontaine’s
disclosure. This would be made still clearer by reference to the drawings
accompanying the patent.
The lugs described by Fontaine have complete
identity of function with those claimed by the appellant; and they perform that
function substantially in the same way. Nor does it matter whether the
appellant’s article is a modification of the Fontaine device, which it is not
necessary to discuss. (Panyard Machine & Mfg. Co. v. Bowman; MacLaughlin v. Lake Erie &
Detroit River Ry. Co.).
In Fontaine’s, as well as in the appellant’s and the respondent’s devices, the
idea is the same and there is substantial identity in the means of carrying it
out. In our view, the difference is a mere variation of details. In Fontaine’s,
the lugs engage the fastener elements immediately above the conical sides of
the slider. In the appellant’s, the lugs reach the elements through a recess or
a hole in the central part of the slider; in Prentice’s, they reach the
elements immediately below the slider. The appellant alleged and brought
evidence to show that Prentice’s was an infringement of its patent. We may
assume that the contention is right. But what amounts to infringement, if
posterior, should, as a general rule, amount to anticipation, if anterior.
Fontaine’s disclosure having been patented in France on the 5th of March, 1924,
or more than two years prior to the application of the appellant in Canada,
this affords sufficient ground for displacing the appellant’s patent (Patent
Act, sec. 7), which must therefore be declared invalid.
Without discussing the other matters involved
herein, it follows that the appeal should be dismissed with costs.
Appeal dismissed with costs.
