INTRODUCTION

As a matter of black-letter law, monopolization under Section 2 of the

Sherman Act does not require proof of specific intent to exclude rivals or harm

competition. It “demands only a general intent to do the act.” Times-Picayune Pub.

Co. v. United States, 345 U.S. 594, 626 (1953) (citing United States v. Aluminum

Co. of Am. (“Alcoa”), 148 F.2d 416, 432 (2d Cir. 1945) (Hand, J.)). That is because

antitrust law is concerned with the competitive impact of conduct, not the

monopolist’s “purity of heart.” Phillip E. Areeda & Herbert Hovenkamp, Antitrust

Law: An Analysis of Antitrust Principles and Their Application ¶ 1506 (Wolters

Kluwer 2025).

The district court departed from this bedrock principle by requiring an

antitrust plaintiff to prove that a biosimilar drug manufacturer intended to exclude

rivals when it made an allegedly anticompetitive acquisition in violation of

Section 2. Requiring proof of intent in a monopolization case “makes nonsense of”

the Sherman Act, Alcoa, 148 F.2d at 432, clashes with Supreme Court and Fourth

Circuit precedent, and contravenes the congressional policy underlying federal

antitrust laws. If such a rule were allowed to stand, it would impede antitrust

enforcement, undermine competitive markets, and harm American consumers. The

Court should correct the district court’s error and reaffirm that anticompetitive

intent is not an element of monopolization under Section 2.

INTEREST OF AMICUS CURIAE

The Federal Trade Commission is a federal agency charged with protecting

America’s consumers from anticompetitive and unfair conduct.1 The Commission

achieves this core mission through vigorous enforcement of federal antitrust laws.

As the primary federal antitrust enforcer in the pharmaceutical industry, the

Commission has extensive experience analyzing and successfully challenging

monopolization and other anticompetitive conduct by drug manufacturers. See,

e.g., FTC v. Actavis, Inc., 570 U.S. 136 (2013); Impax Labs., Inc. v. FTC, 994 F.3d

484 (5th Cir. 2021); FTC v. AbbVie Inc., 976 F.3d 327 (3d Cir. 2020); FTC v.

Shkreli, 581 F. Supp. 3d 579 (S.D.N.Y. 2022), aff’d, 2024 WL 1026010 (2d Cir.

Jan. 23, 2024). 2 The Commission also reviews pharmaceutical patent settlement

agreements, conducts studies, hosts listening sessions, and collaborates with other

agencies to promote drug competition, including competition in the biologic

marketplace.3

Because the Commission has a strong interest in ensuring the proper

application of federal antitrust laws, we submit this brief under Federal Rule of

Appellate Procedure 29(a)(2) to address a legal error in the district court’s

treatment of intent. The Commission takes no position on whether CareFirst would

have survived summary judgment under the correct application of the

monopolization test.

STATEMENT

J&J’s biologic drug Stelara (ustekinumab) is one of the highest-grossing

drugs in the United States. It is approved for the treatment of a variety of

autoimmune conditions, including psoriasis, psoriatic arthritis, Crohn’s disease,

and ulcerative colitis. ECF No. 794 at 2, ¶ 1. J&J was the sole manufacturer of

ustekinumab from its launch in 2009 through 2024. Id. ¶¶ 2–3.

In 2020, J&J acquired Momenta, id. ¶ 19, a pharmaceutical company that

discovers and develops therapies for immune-mediated diseases. 4 With this

Commission Regarding a Collaboration to Advance Competition in the Biologic

Marketplace (Feb. 3, 2020),

daftcbiologicsstatement.pdf.

The FTC’s decision not to take action on this transaction at the time of the

acquisition is not an indication of its legality. See, e.g., Altria Group, Inc. v. Good,

555 U.S. 70, 89–90 (2008) (“The FTC’s failure to require petitioners to correct

their allegedly misleading use of ‘light’ descriptors is not evidence [that the FTC

acquisition, J&J acquired exclusive control over all Momenta patents. Id.

Momenta’s patent portfolio comprised over 500 patents, including four

manufacturing patents covering methods for making biosimilar copies of biologic

drugs (the “Momenta manufacturing patents”). Id. ¶ 16.

In November 2022, J&J sued Amgen for patent infringement after Amgen

notified J&J of its intent to launch a ustekinumab biosimilar. Id. ¶ 21. Three

months later, J&J amended its complaint to allege infringement of the Momenta

manufacturing patents. Id. ¶ 22. In May 2023, J&J settled its claims against

Amgen, granting Amgen a license to use the Momenta manufacturing patents

beginning January 1, 2025. Id. ¶ 23. As a result, Amgen did not begin selling its

ustekinumab biosimilar until January 2025, although it received FDA approval in

October 2023. Id. ¶ 24. J&J settled infringement claims against six other

ustekinumab biosimilar manufacturers in 2023 and 2024 on similar terms. Id. ¶ 25.

In December 2023, CareFirst of Maryland filed a class action complaint

against J&J alleging, among other claims, that J&J willfully maintained its

monopoly power in the ustekinumab market by wrongfully acquiring the Momenta

manufacturing patents and asserting those patents to delay or prevent ustekinumab

competition in violation of Section 2 of the Sherman Act. ECF No. 1 ¶ 280. The

not the same as a policy of approval.”).

district court initially denied J&J’s motion for summary judgment on the Momenta

acquisition theory, ECF No. 794 at 39–45, but later reversed its decision on J&J’s

motion for reconsideration, ECF No. 887 at 4–20.

In its summary judgment opinion, the district court held that the “Fourth

Circuit’s most recent, and thus controlling, articulation of the willfulness standard

is whether the defendant ‘intended to “exclude rivals on some basis other than

efficiency.”’” ECF No. 794 at 40–41 (quoting 2311 Racing LLC v. NASCAR, LLC,

139 F.4th 404, 410 (4th Cir. 2025) (quoting Aspen Skiing Co. v. Aspen Highlands

Skiing Corp., 472 U.S. 585, 605 (1985)); id. (also citing Duke Energy Carolinas,

LLC v. NTE Carolinas II, LLC, 122 F.4th 120, 122 (4th Cir. 2024) (denial of

hearing en banc)). The district court noted that this “articulation of the

monopolization standard is . . . inconsistent with Supreme Court precedent.” ECF

No. 794 at 40–41 n.19. It recognized that “intent is not expressly contemplated and

certainly not required” under the Supreme Court’s burden-shifting liability

framework for monopoly maintenance claims under Section 2, although

“‘knowledge of intent may be [] helpful in cases involving practices . . . which can

have numerous explanations and are very difficult to characterize as competitive or

anticompetitive.’” Id. (quoting Areeda & Hovenkamp ¶ 651).

In its opinion on J&J’s motion for reconsideration, the district court

acknowledged that “[b]oth parties take issue with the Court’s ‘adoption of a legal

5

standard argued by neither side.’” ECF No. 887 at 4 (cleaned up) (quoting ECF

No. 827 at 4; ECF No. 871 at 31). But it reiterated the willfulness standard

articulated in the summary judgment opinion and declined to engage with

CareFirst’s suggestion that the court’s articulation constituted clear error because

CareFirst had not moved for reconsideration. Id. at 5 & n.5.

CareFirst subsequently moved the district court to reconsider its decision on

J&J’s motion for reconsideration and sought to introduce new evidence of J&J’s

specific intent to monopolize because CareFirst had previously “‘litigated this case

based on the understanding that specific intent to monopolize is not an element of

the legal standard for a monopolization claim.’” ECF No. 921 at 2 (quoting ECF

No. 904 at 5–6). The district court stood by “the standard it articulated in its

opinions on summary judgment and reconsideration” and denied CareFirst’s

motion for reconsideration. Id. at 2–4.

ARGUMENT

Monopolization requires only a general intent to perform the act that results

in or maintains monopoly power, not specific intent for the act to have

anticompetitive consequences. The district court erred in its articulation of the

monopolization standard under Section 2 of the Sherman Act by misreading 2311

Racing and Duke Energy to require proof of specific anticompetitive “inten[t] to

‘exclude rivals on some basis other than efficiency.’” ECF No. 794 at 40–41

USCA4 Appeal: 26-1248

(quoting 2311 Racing, 139 F.4th at 410 and Duke Energy, 122 F.4th at 122). The

district court’s misstatement of well-settled monopolization doctrine has the

potential to undermine future antitrust law enforcement efforts, impede

competition, and harm consumers in the form of higher prices or lower quality

goods or services.

I.

WILLFUL ACQUISITION OR MAINTENANCE OF MONOPOLY POWER DOES NOT

REQUIRE PROOF OF SPECIFIC INTENT

Monopolization under Section 2 of the Sherman Act has two elements:

“(1) the possession of monopoly power in the relevant market and (2) the willful

acquisition or maintenance of that power as distinguished from growth or

development as a consequence of a superior product, business acumen, or historic

accident.” Eastman Kodak Co. v. Image Tech. Servs., Inc., 504 U.S. 451, 480

(1992) (quoting United States v. Grinnell Corp., 384 U.S. 563, 570–71 (1966)). 5

Then, defendants can rebut the prima facie case by demonstrating legally

cognizable, “nonpretextual” business justifications. Microsoft, 253 F.3d at 59. If

Courts follow a burden-shifting framework in monopolization cases. See United

States v. Microsoft Corp., 253 F.3d 34, 59 (D.C. Cir. 2001) (en banc); see also New

York v. Actavis PLC, 787 F.3d 638, 652–59 (2d Cir. 2015); LePage’s Inc. v. 3M,

324 F.3d 141, 163–64 (3d Cir. 2003) (en banc); Viamedia, Inc. v. Comcast Corp.,

951 F.3d 429, 463–64 (7th Cir. 2020); FTC v. Qualcomm Inc., 969 F.3d 974, 991

(9th Cir. 2020); Morris Commc’ns Corp. v. PGA Tour, Inc., 364 F.3d 1288, 1293–

98 (11th Cir. 2004). Courts follow a similar burden-shifting framework in cases

brought under Section 1 of the Sherman Act. See, e.g., Ohio v. Am. Express Co.,

585 U.S. 529, 541–42 (2018).

defendant succeeds, the burden shifts back to plaintiff to rebut the justifications—

for example, by showing that they are pretextual—or otherwise overcome them,

for example by showing that the anticompetitive harm outweighs the

procompetitive benefits or that the benefits can be achieved in less restrictive ways.

See Duke Energy Carolinas, LLC v. NTE Carolinas II, LLC, 111 F.4th 337, 343,

365–66 (4th Cir. 2024) (holding that plaintiff created genuine dispute of material

fact regarding defendant’s business justifications that could not be resolved on

summary judgement).

It is black-letter law that an antitrust plaintiff does not need to prove specific

intent to monopolize. Indeed, as a general principle of antitrust, “good motives will

not validate an otherwise anticompetitive practice.” NCAA v. Bd. of Regents of

Univ. of Okla., 468 U.S. 85, 101 n.23 (1984); see also Chicago Bd. of Trade v.

United States, 246 U.S. 231, 238 (1918) (“good intention” cannot “save an

otherwise objectionable” restraint of trade). The reason is that the federal antitrust

laws focus on the “anticompetitive consequences of the act, not the defendant’s

purpose.” Areeda & Hovenkamp ¶ 658; see also Prairie Farmer Pub. Co. v.

Indiana Farmer’s Guide Pub. Co., 88 F.2d 979, 982 (7th Cir. 1937) (explaining

that antitrust laws are “declarative of economic policy, violation of which is

deemed detrimental to common welfare, irrespective of motive or other wrongful

intent”).

Accordingly, as the Supreme Court has repeatedly explained,

“monopolization under § 2 demands only a general intent to do the act.” TimesPicayune, 345 U.S. at 626 (1953) (citing Alcoa, 148 F.2d at 432); see also Aspen

Skiing, 472 U.S. at 602. The “general intent to do the act” is established by the

very fact that the act is done, irrespective of the monopolist’s motive, purpose, or

intent for the act to have anticompetitive consequences. See, e.g., Alcoa, 148 F.2d

at 432; United States v. Griffith, 334 U.S. 100, 105 (1948) (holding that “[i]t is

sufficient that a restraint of trade or monopoly results as the consequence of a

defendant’s conduct or business arrangements” even without the defendant

intending these consequences). “[A]bsent some anomalous accident or involuntary

spasm of industrial consequence,” exclusionary conduct will satisfy the general

intent requirement. See, e.g., United Food & Com. Workers Loc. 1776 v. Takeda

Pharm. Co., 11 F.4th 118, 137 (2d Cir. 2021).

For example, in the seminal Alcoa decision Judge Learned Hand wrote that

“transactions, neutral on their face” and “however innocently” undertaken,

constituted monopolization without proof that the monopolist had “specific intent”

or “motive . . . to exclude others and perpetuate its hold upon the ingot market.”

Alcoa, 148 F.2d at 431–32. The defendant was held liable despite believing—and

the court assuming as true—that it maintained its monopoly power through “fair

means,” and “skill, energy, and initiative.” Id. at 430–31. In reaching this result,

9

USCA4 Appeal: 26-1248

Doc: 35-1

Filed: 06/22/2026

Pg: 15 of 29

Total Pages:(15 of 29)

the court explained that “to limit” improper “exclusion . . . to maneuvres not

honestly industrial, but actuated solely by a desire to prevent competition” would

“emasculate the Act [and] would permit just such consolidations as it was designed

to prevent.” Id. at 431. This is why antitrust liability turns on the anticompetitive

consequences of the defendant’s actions, rather than its intentions. To read Section

2’s prohibition against monopolization to demand specific intent “makes

nonsense” of the Sherman Act. Aspen Skiing, 472 U.S. at 602 n.28 (quoting Alcoa,

148 F.2d at 432).

This distinction between general intent to undertake an exclusionary act and

specific, anticompetitive intent to harm competition reflects a key difference

between monopolization and attempted monopolization. Attempted

monopolization requires “specific intent to monopolize.” Spectrum Sports, Inc. v.

McQuillan, 506 U.S. 447, 459 (1993); E.I. du Pont de Nemours & Co. v. Kolon

Indus., Inc., 637 F.3d 435, 453 (4th Cir. 2011).6 This makes sense because, as the

The other circuit courts make the same distinction. See, e.g., Conwood Co. v. U.S.

Tobacco Co., 290 F.3d 768, 782 (6th Cir. 2002) (“[F]or a ‘completed’

monopolization claim to succeed, the plaintiff must prove a general intent on the

part of the monopolist to exclude; while by contrast, to prevail on a ‘mere’ attempt

claim, the plaintiff must prove a specific intent to ‘destroy competition or build a

Supreme Court has repeatedly explained, “‘Where acts are not sufficient in

themselves to produce a result which the law seeks to prevent—for instance, the

monopoly— . . . an intent to bring it to pass is necessary in order to produce a

dangerous probability that it will happen.’” Spectrum Sports, 506 U.S. at 455

(quoting the seminal attempted monopolization opinion Swift & Co. v. United

States, 196 U.S. 375, 396 (1905) (Holmes, J.)).

But where acts result in or maintain a monopoly, an inquiry into the

monopolist’s anticompetitive intent is not required, and courts instead assess

whether the defendant’s conduct is “exclusionary” or “anticompetitive”—that is,

whether the conduct has hampered the growth of rivals through means other than

“competition on the merits.” Aspen Skiing, 472 U.S. at 602, 605 & n.32; see also

Kolon, 637 F.3d at 441; Microsoft, 253 F.3d at 62, 65. In this context, a plaintiff

can use the defendant’s anticompetitive intent to bolster a showing of the likely

exclusionary effect of the defendant’s conduct, but anticompetitive intent is not

required. See, e.g., Griffith, 334 U.S. at 105; McWane, Inc. v. FTC, 783 F.3d 814,

840 (11th Cir. 2015) (“‘Evidence of the intent behind the conduct of a monopolist

is relevant only to the extent it helps us understand the likely effect of the

monopolist’s conduct.’” (quoting Microsoft, 253 F.3d at 59)). “To require a greater

showing would cripple the Act.” Griffith, 334 U.S. at 105.

The Fourth Circuit’s cases have long reflected this important difference

between “the specific intent required to prove an illegal attempt to monopolize”

and “the general intent which, accompanied by monopoly power, constitutes the

offense of monopolization.” Greenville Pub. Co. v. Daily Reflector, Inc., 496 F.2d

391, 396 (4th Cir. 1974). For example, Kolon involved both a claim for

monopolization and attempted monopolization. 637 F.3d 435. In analyzing the

willful maintenance element, the Court focused on the competitive effects of

alleged exclusive agreements without mentioning specific intent to monopolize. Id.

at 451–53. Without addressing specific intent, it held that “Kolon adequately pled

all elements of its monopolization claim.” Id. at 453. After reaching that

conclusion, the Fourth Circuit then turned to Kolon’s attempted monopolization

claim and analyzed, for the first time, whether Kolon had alleged DuPont’s

“specific intent to monopolize.” Id.

THE DISTRICT COURT MISAPPLIED SUPREME COURT AND FOURTH CIRCUIT

PRECEDENT TO REQUIRE PROOF OF SPECIFIC INTENT

The district court erred in departing from binding Supreme Court and Fourth

Circuit precedent by requiring proof of anticompetitive intent for CareFirst’s

monopolization claim. The district court even acknowledged that anticompetitive

“intent is . . . certainly not required” to prove monopolization under Supreme Court

precedent. ECF No. 794 at 40–41 n.19. But it held that the “Fourth Circuit’s most

recent, and thus controlling, articulation of the willfulness standard is whether the

defendant ‘intended to exclude rivals on some basis other than efficiency.’” Id. at

40–41 (quoting 2311 Racing, 139 F.4th at 410 and Duke Energy, 122 F.4th at

122).7 The district court recognized that a specific intent requirement, in its own

words, would be “inconsistent with Supreme Court precedent,” but it disregarded

the Supreme Court’s clear and repeated resolution of this issue and adopted a new,

erroneous standard. ECF No. 794 at 40–41 n.19.

Two isolated statements of dicta in 2311 Racing and Duke Energy appear to

be the district court’s source of confusion. In 2311 Racing, the Fourth Circuit

stated that “Section 2 requires that the defendant have engaged in anticompetitive

conduct—i.e., conduct intended to ‘exclude rivals on some basis other than

efficiency.’” 2311 Racing, 139 F.4th at 410 (quoting Aspen Skiing, 472 U.S. at

605). The Fourth Circuit used similar language in Duke Energy, 111 F.4th at 353.

(“But the second element is at issue—whether Duke Energy maintained its power

The District Court was mistaken not only on the law of antitrust, but also on the

law of precedent. In the Fourth Circuit, a panel’s “most recent . . . articulation” of

the law is not the “controlling” one. ECF No. 794 at 40. “When published panel

opinions are in direct conflict on a given issue, the earliest opinion controls, unless

the prior opinion has been overruled by an intervening opinion from this court

sitting en banc or the Supreme Court.” McMellon v. United States, 387 F.3d 329,

333 (4th Cir. 2004). To the extent the Supreme Court’s unambiguous statements on

this issue do not settle the matter—and to the further extent this panel shares the

district court’s reading of 2311 Racing and Duke Energy (which it should not)—

the prior panel rule would nonetheless warrant reversal and application of the

correct rule: specific intent is not an element of a monopolization claim. See, e.g.,

Kolon, 637 F.3d at 451–53; Greenville Pub., 496 F.2d at 396–98.

through anticompetitive conduct, i.e., conduct intended to ‘exclude rivals on some

basis other than efficiency.’” (quoting Aspen Skiing, 472 U.S. at 605)).8

The district court improperly “parsed” these statements in 2311 Racing and

Duke Energy “‘as though we were dealing with language of a statute’” to create a

new intent requirement that conflicts with a century’s worth of precedent. Nat’l

Pork Producers Council v. Ross, 598 U.S. 356, 373–74 (2023) (quoting Reiter v.

Sonotone Corp., 442 U.S. 330, 341 (1979)). 9 But these statements must be read in

reference to Aspen Skiing, which the Fourth Circuit quoted in each case in support.

Aspen Skiing shows that “knowledge of intent,” though not required for

liability, “may help the court to interpret facts and to predict consequences” and to

distinguish competition on the merits from improper exclusion, particularly where

the challenged conduct by a monopolist can have numerous explanations. Areeda

& Hovenkamp ¶ 651 (quoting Chicago Bd. of Trade, 246 U.S. at 238). There, a

monopolist ski resort unilaterally refused to deal with its competitor after years of

jointly marketing mountain passes. To determine whether “it is fair to characterize

In its opinion, the district court cited to Judge Niemeyer’s statement in support of

denying rehearing en banc. See ECF No. 794 at 41 (citing 122 F.4th 120, 122

(Mem.)). Though such a statement is not precedential, the same language appears

in the published panel opinion.

its behavior as predatory,” the Supreme Court analyzed whether the monopolist

“has been ‘attempting to exclude rivals on some basis other than efficiency.’”

Aspen Skiing, 472 U.S. at 605 (quoting Robert H. Bork, The Antitrust Paradox 138

(1978)).

To answer that question, the Court looked at anticompetitive effects of the

monopolist’s refusal to deal by “examin[ing] the effect of the challenged pattern of

conduct on consumers, on Ski Co.’s smaller rival, and on Ski Co. itself.” Id. at 605.

Concluding that both consumers and the rival were adversely affected by the

conduct, and the monopolist lacked any business justification for it, the Court held

that “the evidence supports an inference that Ski Co. was not motivated by

efficiency concerns and that it was willing to sacrifice short-run benefits and

consumer goodwill in exchange for a perceived long-run impact on its smaller

rival.” Id. at 610–11. While the Court used evidence of intent in its analysis of

business justifications, it made clear that “intent is merely relevant to the question

whether the challenged conduct is fairly characterized as ‘exclusionary’ or

‘anticompetitive,’” id. at 602 (emphasis added), and reiterated that to demand

specific intent in a monopolization case “makes nonsense of” Section 2. Id. at 602

n.28 (quoting Alcoa, 148 F.2d at 432).

The Fourth Circuit’s opinions in 2311 Racing and Duke Energy faithfully

applied this Supreme Court precedent. Anticompetitive intent was not discussed at

all in 2311 Racing. The conduct at issue was a contractual provision “requiring a

prospective participant” in NASCAR races “to give a release for past conduct as a

condition for doing business.” 2311 Racing, 139 F.4th at 410. The Fourth Circuit

concluded that “[t]he effect of such a release” was “not to eliminate or injure

competition.” Id. It vacated the district court’s preliminary injunction because

“[n]either the plaintiffs nor the district court has shown how the release would have

injured competition.” Id. (emphasis in original).

To the extent Duke Energy relied on evidence of anticompetitive intent, it

did so consistent with Supreme Court instructions to use intent only to “help the

court to interpret facts and to predict consequences.” Chicago Bd. of Trade, 246

U.S. at 238; see also Aspen Skiing, 472 U.S. at 602. The Fourth Circuit noted in

Duke Energy that the evidence of “anticompetitive malice . . . bolsters our

conclusion that the case is trial worthy.” 111 F.4th at 367. But it focused on the

nature and likely effects of the challenged conduct to determine whether the

incumbent competed on the merits or engaged in anticompetitive conduct. See,

e.g., id. at 362 (“The record is thus sufficient to support a finding that Duke’s

blend-and-extend strategy, coupled with its Butler Warner agreement,

independently produced anticompetitive effects.”).

Nor, contrary to J&J’s arguments below, does Oksanen v. Page Mem’l

Hosp., 945 F.2d 696 (4th Cir. 1991) (en banc), require proof of “anticompetitive

purposes” or “knowledge” that the challenged conduct “would afford [defendant]

monopoly power.” ECF No. 605 at 22–23 (citing Oksanen and arguing that

“willfulness” requires showing “that a defendant acted for anticompetitive

purposes”). In reviewing a grant of summary judgment, Oksanen analyzed the

second element of the monopolization test—willful acquisition or maintenance of

monopoly power (which the Court dubbed “monopolistic intent” as a shorthand).

The Court noted that the defendants had offered a procompetitive justification,

which the plaintiff had not rebutted. It concluded that a plaintiff must show “that a

jury could find no valid business reason or concern for efficiency” for the

challenged conduct. Oksanen, 945 F.2d at 710 (quoting White v. Rockingham

Radiologists, Ltd., 820 F.2d 98, 105 (4th Cir. 1987)). To understand this statement,

recall that Section 2 claims follow a familiar burden-shifting approach, where

defendants may rebut a prima facie showing of monopolization by proving valid

business justifications for their conduct. See supra Section I. In turn, plaintiffs may

rebut any proffered valid business justifications, such as by showing that those

justifications are pretextual or are outweighed by anticompetitive harms. See

Microsoft, 253 F.3d at 58–59.

Oksanen and White—decided 35 and 39 years ago, respectively—fit

comfortably within the burden-shifting approach that has emerged in ensuing

decades. See supra Section I. Each determined that plaintiffs failed to offer

17

USCA4 Appeal: 26-1248

evidence sufficient to rebut proffered valid business justifications for the

challenged conduct, which meant that plaintiffs could not succeed on the second

element of a monopolization claim. Indeed, a later unpublished decision from this

Court applied Oksanen in exactly that way. See Imaging Ctr., Inc. v. W. Maryland

Health Sys., Inc., 158 F. App’x 413, 420–21 (4th Cir. 2005) (holding that conduct

did not violate Section 2 where defendant proffered “valid business and patient

care reasons” and plaintiff “had offered no effective rebuttal to these

procompetitive justifications” because claims of “reduced output and quality” were

“unsupported” and prices did not increase (quoting Oksanen, 945 F.2d at 710)).

Nothing in Oksanen or White requires any showing of specific intent, which would

be contrary to the Supreme Court’s clear directive in Aspen Skiing.

Nor is the law’s protection of “unwitting” monopolists that had market

dominance “thrust upon” them “by force of accident” tantamount to requiring

proof of specific intent (or knowledge, as J&J calls it).10 See Alcoa, 148 F.2d at

J&J argued below that willfulness required showing specific intent. See, e.g.,

ECF No. 605 at 17 (“Plaintiffs must also show that, at the time of the acquisition,

J&J knew or intended that, by acquiring Momenta, it would be maintaining or

adding to its alleged monopoly power . . . .”); ECF No. 542 at 24 (“Plaintiffs must

also show that . . . J&J knew or intended that . . . it would be maintaining or adding

to its alleged monopoly power.”); ECF No. 444 at 39 (“Establishing willfulness

requires evidence showing ‘monopolistic intent’—i.e., that a defendant acted for

anticompetitive purposes . . . .”). J&J later also argued that “Plaintiffs must show,

at minimum, that J&J acted with knowledge that the Momenta Manufacturing

Patents could be used to exclude with respect to Stelara” and “and would afford it

429–30. This screen is merely meant to separate monopolies resulting from natural

growth or external supply-and demand-factors—such as “changes in taste or in

cost”—from monopolies resulting from defendant’s exclusionary actions. Id. As

discussed in Section I, whether an act is exclusionary turns on whether it is

“competition on the merits”; specific intent can be probative of the likely

exclusionary effect of the conduct, but its absence does not save an action that is

otherwise anticompetitive. See, e.g., Alcoa, 148 F.2d at 430–32. This is particularly

true where the challenged conduct is a consummated acquisition and its effects can

be readily seen. The federal antitrust agencies’ Merger Guidelines confirm that the

agencies “give little weight” to the absence of specific intent in evaluating

acquisitions. U.S. Dep’t of Just. & Fed. Trade Comm’n, Merger Guidelines § 4.1

(2023).

Applying the correct standard for willfulness under Supreme Court and

Fourth Circuit precedent, J&J’s acquisition of the Momenta manufacturing patents

is sufficient to establish a “willful” act. Indeed, a leading antitrust treatise notes

monopoly power.” ECF No. 605 at 23. J&J contends that this standard is somehow

different from specific intent to monopolize. Id. Such a distinction has no basis in

law. “[N]o monopolist monopolizes unconscious of what he is doing.” Aspen

Skiing, 472 U.S. at 602 (quoting Alcoa, 148 F.2d at 432). There is no practical

difference between having to prove that J&J bought the patents knowing they

would afford it monopoly power and intending that they would afford it monopoly

power. Thus, J&J’s knowledge standard is simply a back door to specific intent.

that “[a]cquisition by a monopolist of exclusive rights in related patents should

presumptively be a § 2 ‘exclusionary practice,’ and this applies with equal force to

the acquisition of a firm that owns such patents, if the effect of the acquisition is to

give the acquirer an exclusive right in them and this serves to increase or prolong

the monopolist’s market power.” Areeda & Hovenkamp ¶ 707. As alleged in the

complaint, J&J was already a monopolist at the time of the challenged acquisition.

ECF No. 641 ¶¶ 208–15. And it allegedly extended its monopoly power, not by

“historic accident,” Grinnell, 384 U.S. at 571, but through the acquisition of the

Momenta manufacturing patents as part of the Momenta transaction for $6.5

billion. Antitrust liability does not turn on the rigor of J&J’s due diligence or what

J&J knew about the Momenta manufacturing patents at the time of the

acquisition.11 It is sufficient that J&J bought those patents to prove a willful act. Of

course, whether such act is ultimately unlawful depends on the plaintiff’s ability to

prove monopoly power and the likely anticompetitive effects of the transaction.

Requiring proof that defendant knew of the patents’ scope or potential

anticompetitive consequences of the transaction is not only contrary to the law, it

would also hamper Section 2 enforcement of anticompetitive acquisitions while

increasing burdens on parties. See Areeda & Hovenkamp ¶ 1506 (inquiring into a

defendant’s mental state can “invite the parties to examine thousands of

documents, to depose nearly everyone, to resist early disposition on the ground that

disputed intent requires trial, to burden the judge and jury with ambiguous

evidence, and to invite decision on the basis of relative purity of heart rather than

competitive impact”).

CONCLUSION

By mistakenly requiring proof of specific intent, the district court gives a

monopolist a free pass to avoid liability when its conduct harms competition on the

merits but there is no evidence that it intended to do so—either because it actively

avoided creating such evidence or because that evidence does not exist. Such an

intent-based test makes nonsense of the Sherman Act, contradicts precedent, and

risks undermining vigorous market competition and effective government

enforcement if left unchecked. Great for monopolists, bad for American

consumers.

The Court should correct the district court’s legal error and hold that proof

of “willful” conduct does not require proof of specific intent to monopolize.
