The owner of a method patent who authorize manufacturers to use
it only with materials furnished by him may not enjoin infringement
by one who supplies the manufacturer with material for use by the
patented method and aids in such use.

Certiorari, 313 U.S. 558, to review the affirmance of a decree
of the District Court,
32 F. Supp.
690, which dismissed the bill in a suit to enjoin infringement
of a patent, and for an accounting.
MR. CHIEF JUSTICE STONE delivered the opinion of the Court.
This is a companion case to
Morton Salt Company v. G. S.
Suppiger Co., ante, p.
314 U. S. 488, and
involves the question whether the owner of a method patent who
authorizes manufacturers to use it only with materials furnished by
him may enjoin infringement by one who supplies
Page 314 U. S. 496
the manufacturer with materials for use by the patented method,
and aids in such use.
Petitioner brought the present suit for an injunction and an
accounting for infringement of the Ellis Patent, No. 1,830,428, of
November 3, 1931, for a method of reinforcing insoles in shoe
manufacture. Respondents denied infringement and set up as a
further defense petitioner's misuse of the patent by permitting its
use only with the unpatented materials sold by petitioner. The
District Court,
32 F. Supp.
690, sustained this defense, and the Court of Appeals for the
First Circuit affirmed. 117 F.2d 829. We granted certiorari, 313
U.S. 558, because of the importance of the question presented and
because we wished to consider this with the
Morton Salt
Company case.
Claim 4 of the patent is for a method
"of reinforcing insoles which comprises applying, at room
temperature, to a strip of reinforcing material provided with a dry
coating of a cement having a substantial rubber content, a coating
of adhesive containing a relatively large amount of rubber and of
such a character that it will be effective even when freshly
applied to cause quick adhesion of the reinforcing material and the
material of the insole, and applying to each other, still at room
temperature, a portion of the coated strip and the insole to be
reinforced."
Both courts below sustained the validity of claim 4 and held it
was infringed by respondents' selling to purchasers of petitioner's
materials like material for use with the patented process. But both
held that petitioner was debarred from enjoining the infringement
because of the manner of conducting its business, which is to
supply shoe manufacturers, for use in reinforcing insoles,
pre-coated fabric which it has slit into strips of suitable width
for use by the patented method. If the manufacturer desires, he
provides the fabric and petitioner pre-coats and slits it.
Petitioner
Page 314 U. S. 497
supplies adhesive of high rubber content to be applied to the
pre-coated fabric at the factory, just before the application of
the reinforcing material to the insole. It also furnishes patented
machines suitable for applying the adhesive to the strips, the
machines remaining petitioner's property.
As compensation, petitioner makes a single charge to the shoe
manufacturer at a rate per web yard of fabric used, and, if the
manufacturer does not furnish the fabric, the price of that is
added to the charge. Petitioner has not granted to shoe
manufacturers, or asked them to take, written licenses. The courts
below held that petitioner's sale to manufacturers of the
unpatented materials for use by the patented method operated as a
license to use the patent with that material alone, and thus
restrained competition with petitioner in the sale of the
unpatented material, as in
Carbice Corp. v. American Patents
Corp., 283 U. S. 27, and
Leitch Mfg. Co. v. Barber Co., 302 U.
S. 458.
Petitioner insists that the respondents' acts of infringement,
as found by the district court, were not limited to the sale of
material for use by the patented method, as in the
Carbice
and
Leitch cases, but amounted to active inducement of
infringement by the shoe manufacturers and to cooperation with
their infringing acts. Petitioner argues that, even though, under
the
Carbice and
Leitch cases, it has "no right to
be free from competition in the sale" of the materials, it has the
right under the patent law to restrain infringement in any manner
other than by the competitive sale of the unpatented materials.
We may assume, for purposes of decision, that respondents'
infringement did extend beyond the mere sale of the materials to
the manufacturers. But, in view of petitioner's use of the patent
as the means of establishing a limited monopoly in its unpatented
materials, and for the reasons given in our opinion in the
Morton Salt Company case,
Page 314 U. S. 498
we hold that the maintenance of this suit to restrain any form
of infringement is contrary to public policy, and that the district
court rightly dismissed it.
It is without significance that, as petitioner contends, it is
not practicable to exploit the patent rights by granting licenses
because of the preferences of manufacturers and of the methods by
which petitioner has found it convenient to conduct its business.
The patent monopoly is not enlarged by reason of the fact that it
would be more convenient to the patentee to have it so, or because
he cannot avail himself of its benefits within the limits of the
grant.
Despite this contention, petitioner suggests that it is entitled
to relief because it is now willing to give unconditional licenses
to manufacturers on a royalty basis, which it offers to do. It will
be appropriate to consider petitioner's right to relief when it is
able to show that it has fully abandoned its present method of
restraining competition in the sale of unpatented articles, and
that the consequences of that practice have been fully
dissipated.
Affirmed.
MR. JUSTICE ROBERTS took no part in the decision of this
case.
