Petitioner, in answer to respondent's suit for patent
infringement, denied the infringement and counterclaimed for a
declaratory judgment holding the patent invalid. After discovery
proceedings, respondent moved to dismiss its complaint because the
patent had expired. Petitioner then amended its counterclaim to
charge that respondent had illegally monopolized commerce by having
fraudulently and in bad faith obtained and maintained the patent in
violation of the antitrust laws, and sought treble damages. The
District Court dismissed the complaint and the counterclaim, and
the Court of Appeals affirmed.
Held: The enforcement of a patent procured by fraud on
the Patent Office may violate § 2 of the Sherman Act, provided all
other elements to establish a § 2 monopolization charge are proved,
in which event the treble damage provisions of § 4 of the Clayton
Act would be available to the injured party. Pp.

(a) Petitioner is not barred by the rule that only the United
States may sue to cancel a patent, since, by its counterclaim under
the Clayton Act, it does not directly seek the patent's annulment.

MR. JUSTICE CLARK delivered the opinion of the Court.
The question before us is whether the maintenance and
enforcement of a patent obtained by fraud on the Patent Office may
be the basis of an action under § 2 of the Sherman Act, [
Footnote 1] and therefore subject to a
treble damage claim by an injured party under § 4 of the Clayton
Act. [
Footnote 2] The
respondent, Food Machinery, & Chemical Corp. (hereafter Food
Machinery), filed this suit for infringement of its patent No.
2,328,655 covering knee-action swing diffusers used in aeration
equipment for sewage treatment systems. [
Footnote 3] Petitioner, Walker Process Equipment,
Page 382 U. S. 174
Inc. (hereafter Walker), denied the infringement and
counterclaimed for a declaratory judgment that the patent was
invalid. After discovery, Food Machinery moved to dismiss its
complaint with prejudice because the patent had expired. Walker
then amended its counterclaim to charge that Food Machinery had
"illegally monopolized interstate and foreign commerce by
fraudulently and in bad faith obtaining and maintaining . . . its
patent . . . well knowing that it had no basis for . . . a
patent."
It alleged fraud on the basis that Food Machinery had sworn
before the Patent Office that it neither knew nor believed that its
invention had been in public use in the United States for more than
one year prior to filing its patent application when, in fact, Food
Machinery was a party to prior use within such time. The
counterclaim further asserted that the existence of the patent had
deprived Walker of business that it would have otherwise enjoyed.
Walker prayed that Food Machinery's conduct be declared a violation
of the antitrust laws and sought recovery of treble damages.
The District Court granted Food Machinery's motion and dismissed
its infringement complaint along with Walker's amended
counterclaim, without leave to amend and with prejudice. The Court
of Appeals for the Seventh Circuit affirmed, 335 F.2d 315. We
granted certiorari, 379 U.S. 957. We have concluded that the
enforcement of a patent procured by fraud on the Patent Office may
be violative of § 2 of the Sherman Act provided the other elements
necessary to a § 2 case are present. In such event, the treble
damage provisions of § 4 of the Clayton Act would be available to
an injured party.
I
As the case reaches us, the allegations of the counterclaim, as
to the fraud practiced upon the Government by Food Machinery as
well as the resulting damage suffered
Page 382 U. S. 175
by Walker are taken as true. [
Footnote 4] We, therefore, move immediately to a
consideration of the legal issues presented.
Both Walker and the United States, which appears as
amicus
curiae, argue that if Food Machinery obtained its patent by
fraud, and thereafter used the patent to exclude Walker from the
market through "threats of suit" and prosecution of this
infringement suit, such proof would establish a
prima
facie violation of § 2 of the Sherman Act. On the other hand,
Food Machinery says that a patent monopoly and a Sherman Act
monopolization cannot be equated; the removal of the protection of
a patent grant because of fraudulent procurement does not
automatically result in a § 2 offense. Both lower courts seem to
have concluded that proof of fraudulent procurement may be used to
bar recovery for infringement,
Precision Instrument Mfg. Co. v.
Automotive Maintenance Machinery Co., 324 U.
S. 806 (1945), but not to establish invalidity. As the
Court of Appeals expressed the proposition, "only the government
may
annul or set aside' a patent," citing Mowry v.
Whitney, 14 Wall. 434 (1872). It went on to state
that no case had
"decided, or hinted that fraud on the Patent Office may be
turned to use in an original affirmative action, instead of as an
equitable defense. . . . Since Walker admits that its antitrust
theory depends on its ability to prove fraud on the Patent Office,
it follows that . . . Walker's second amended counterclaim failed
to state a claim upon which relief could be granted."
335 F.2d at 316.
II
We have concluded, first, that Walker's action is not barred by
the rule that only the United States may sue to cancel or annul a
patent. It is true that there is no
Page 382 U. S. 176
statutory authority for a private annulment suit and the
invocation of the equitable powers of the court might often subject
a patentee "to innumerable vexatious suits to set aside his
patent."
Mowry, supra, 81 U. S. But
neither reason applies here. Walker counterclaimed under the
Clayton Act, not the patent laws. While one of its elements is the
fraudulent procurement of a patent, the action does not directly
seek the patent's annulment. The gist of Walker's claim is that,
since Food Machinery obtained its patent by fraud it cannot enjoy
the limited exception to the prohibitions of § 2 of the Sherman
Act, but must answer under that section and § 4 of the Clayton Act
in treble damages to those injured by any monopolistic action taken
under the fraudulent patent claim. Nor can the interest in
protecting patentees from "innumerable vexatious suits" be used to
frustrate the assertion of rights conferred by the antitrust laws.
It must be remembered that we deal only with a special class of
patents,
i.e., those procured by intentional fraud.
Under the decisions of this Court, a person sued for
infringement may challenge the validity of the patent on various
grounds, including fraudulent procurement.
E.g., Precision
Instrument Mfg. Co. v. Automotive Maintenance Machinery Co.,
324 U. S. 806
(1945);
Hazel-Atlas Co. v. Hartford-Empire Co.,
322 U. S. 238
(1944);
Keystone Driller Co. v. General Excavator Co.,
290 U. S. 240
(1933). In fact, one need not await the filing of a threatened suit
by the patentee; the validity of the patent may be tested under the
Declaratory Judgment Act, 28 U.S.C. § 2201 (1964 ed.).
See
Kerotest Mfg. Co. v. C-O Two Fire Equipment Co., 342 U.
S. 180,
342 U. S. 185
(1952). At the same time, we have recognized that an injured party
may attack the misuse of patent rights.
See, e.g., Mercoid
Corp. v. Mid-Continent Investment Co., 320 U.
S. 661 (1944). To permit recovery of treble damages for
the fraudulent procurement of the patent
Page 382 U. S. 177
coupled with violations of § 2 accords with these long
recognized procedures. It would also promote the purposes so well
expressed in
Precision Instrument, supra, at
324 U. S.
816:
"A patent, by its very nature, is affected with a public
interest. . . . [It] is an exception to the general rule against
monopolies, and to the right to access to a free and open market.
The far-reaching social and economic consequences of a patent,
therefore, give the public a paramount interest in seeing that
patent monopolies spring from backgrounds free from fraud or other
inequitable conduct, and that such monopolies are kept within their
legitimate scope."
III
Walker's counterclaim alleged that Food Machinery obtained the
patent by knowingly and willfully misrepresenting facts to the
Patent Office. Proof of this assertion would be sufficient to strip
Food Machinery of its exemption from the antitrust laws. [
Footnote 5] By the same token, Food
Machinery's good faith would furnish a complete defense. This
includes an honest mistake as to the effect of prior installation
upon patentability -- so-called "technical fraud."
To establish monopolization or attempt to monopolize a part of
trade or commerce under § 2 of the Sherman Act, it would then be
necessary to appraise the exclusionary power of the illegal patent
claim in terms of the relevant market for the product involved.
Without a definition of that market, there is no way to measure
Food Machinery's ability to lessen or destroy competition. It may
be that the device -- knee-action swing diffusers
Page 382 U. S. 178
-- used in sewage treatment systems does not comprise a relevant
market. There may be effective substitutes for the device which do
not infringe the patent. This is a matter of proof, as is the
amount of damages suffered by Walker.
As respondent points out, Walker has not clearly articulated its
claim. It appears to be based on a concept of
per se
illegality under § 2 of the Sherman Act. But, in these
circumstances, the issue is premature. As the Court summarized in
White Motor Co. v. United States, 372 U.
S. 253 (1963), the area of
per se illegality is
carefully limited. We are reluctant to extend it on the bare
pleadings and absent examination of market effect and economic
consequences.
However, even though the
per se claim fails at this
stage of litigation, we believe that the case should be remanded
for Walker to clarify the asserted violations of § 2, and to offer
proof thereon. The trial court dismissed its suit not because
Walker failed to allege the relevant market, the dominance of the
patented device therein, and the injurious consequences to Walker
of the patent's enforcement, but rather on the ground that the
United States alone may "annul or set aside" a patent for fraud in
procurement. The trial court has not analyzed any economic data.
Indeed, no such proof has yet been offered, because of the
disposition below. In view of these considerations, as well as the
novelty of the claim asserted and the paucity of guidelines
available in the decided cases, this deficiency cannot be deemed
crucial. Fairness requires that, on remand, Walker have the
opportunity to make its § 2 claims more specific, to prove the
alleged fraud, and to establish the necessary elements of the
asserted § 2 violation.
Reversed and remanded.

MR. JUSTICE HARLAN (concurring).
I join the Court's opinion. I deem it appropriate, however, to
add a few comments to what my Brother CLARK has written because the
issue decided is one of first impression and to allay possible
misapprehension as to the possible reach of this decision.
We hold today that a treble damage action for monopolization
which, but for the existence of a patent, would be violative of § 2
of the Sherman Act may be maintained under § 4 of the Clayton Act
if two conditions are satisfied: (1) the relevant patent is shown
to have been procured by knowing and willful fraud practiced by the
defendant on the Patent Office or, if the defendant was not the
original patent applicant, he had been enforcing the patent with
knowledge of the fraudulent manner in which it was obtained; and
(2) all the elements otherwise necessary to establish a § 2
monopolization charge are proved. Conversely, such a private cause
of action would not be made out if the plaintiff: (1) showed no
more than invalidity of the patent arising, for example, from a
judicial finding of "obviousness," or from other factors sometimes
compendiously referred to as "technical fraud"; or (2) showed
fraudulent procurement, but no knowledge thereof by the defendant;
or (3) failed to prove the elements of a § 2 charge even though he
has established actual fraud in the procurement of the patent and
the defendant's knowledge of that fraud.
It is well also to recognize the rationale underlying this
decision, aimed of course at achieving a suitable accommodation in
this area between the differing policies of the patent and
antitrust laws. To hold, as we do, that private suits may be
instituted under § 4 of the Clayton Act to recover damages for
Sherman Act monopolization knowingly practiced under the guise of a
patent
Page 382 U. S. 180
procured by deliberate fraud, cannot well be thought to impinge
upon the policy of the patent laws to encourage inventions and
their disclosure. Hence, as to this class of improper patent
monopolies, antitrust remedies should be allowed room for full
play. On the other hand, to hold, as we do not, that private
antitrust suits might also reach monopolies practiced under patents
that for one reason or another may turn out to be voidable under
one or more of the numerous technicalities attending the issuance
of a patent, might well chill the disclosure of inventions through
the obtaining of a patent because of fear of the vexations or
punitive consequences of treble damage suits. Hence, this private
antitrust remedy should not be deemed available to reach § 2
monopolies carried on under a nonfraudulently procured patent.
These contrasting factors at once serve to justify our present
holding and to mark the limits of its application.
