Monopoly and Monopolization - Fundamental But Separate Concepts in U.S. Antitrust Law

CRS Report for Congress
Monopoly and Monopolization —
Fundamental But Separate Concepts in
U.S. Antitrust Law
Janice E. Rubin
Legislative Attorney
American Law Division
Antitrust doctrine holds that viable competition will best protect consumers; it is
concerned with the viability of individual competitors only insofar as their fates affect
marketplace competitiveness. Moreover, the Rule of Reason1 generally modified
“competition” with “reasonable.” Viewed in the context of the Rule of Reason, the
general prohibitions against monopolization and attempted monopolization (Sherman
Act § 2, Clayton Act §7) and any assessment of “unfair acts” in commerce (Federal
Trade Commission Act § 5) require two inquiries: whether an entity is in fact a
monopolist; and whether that monopolist has unlawfully monopolized the market(s)
within which it operates (the applicable, "relevant market," which may be either product-
or geographically based, or both). This report will attempt to illustrate the difference
between the concepts of “monopoly” and “monopolization” by touching on the
monopoly/monopolization thinking in the Antitrust Division of the Department of
Justice (DOJ) and the Federal Trade Commission (FTC), as illustrated in (1) statements
on merger enforcement made by recent antitrust enforcement officials (generally
indicative of the agencies’ concerns about competitive conditions and the effect of2
various market transactions), (2) the 1992 Horizontal Merger Guidelines and (3) some
observations on the Government actions against the Microsoft and Intel Corporations.

1 Standard Oil Co. of New Jersey v. United States, 221 U.S. 1 (1911). Rule of Reason analysis
balances (with the exception of the relatively few instances of per se violations of the antitrust
laws (e.g., price fixing, boycotts)) the anticompetitive results of a transaction against any
procompetitive effects that might be produced.

Guidelines, published and released April 2, 1992 [“Merger Guidelines” or “Guidelines”],

(April 2, 1992) and 1806 ATRR 359 (April 10, 1997).

Section 2 of the Sherman Act prohibits both the monopolization and attempted
monopolization of interstate or foreign trade or commerce.3 Section 7 of the Clayton Act
prohibits mergers or acquisitions “where in any line of commerce or any activity affecting
commerce in any section of the country, the effect of such [transaction] ... may be
substantially to lessen competition, or to tend to create a monopoly.”4 Section 5 of the
Federal Trade Commission (FTC) Act prohibits “unfair acts” in commerce.5
A shorthand definition of “monopoly” is “the power to control prices or exclude
competition.”6 The significance of the ability to exclude competition is, however, as is
the ability to control prices, in the supposed deleterious effect of the lack of competition
on, consumers, who are presumed to benefit from the existence of largely competitive
markets, and not on the excluded competitors:
‘[t]he antitrust injury requirement obligates [complainants] to demonstrate, as a
threshold matter, “that the challenged conduct has had an actual adverse effect on
competition as a whole in the relevant market; to prove it has been harmed as an7
individual competitor will not suffice.”’
“... it is axiomatic that the antitrust laws were passed for ‘the protection of8
competition, not competitors.’”
There is no concept of “no fault” monopolization in United States antitrust law;9 absent
a finding by a court of “guilty behavior,”10 therefore, there can be no finding of
“monopolization”: a finding of “monopoly power” does not, by itself, necessarily equate
to a finding of the monopolization prohibited by either section 7 of the Clayton Act or11
section 2 of the Sherman Act, or the “unfair practices” prohibited by section 5 of the
FTC Act. Practically, then, there must be a determination of the market(s) within which

9 I.e., there is no “bright line” for the size beyond which an entity may grow before it is deemed
a “monopoly.” Attempts during the 1970s to create “no fault monopolization” were not
successful (e.g., S. 1167, 93d Congress, sponsored by Senator Philip Hart).
10 I.e., predatory pricing or tying the purchase of an unwanted product to the purchase of one over
which the seller has a monopoly. In this respect, note cases filed against Microsoft and Intel by
DOJ and the FTC, discussed, infra, beginning at p. 4.
11 “... [the] power that, [for example], automobile or soft-drink manufacturers [who, admittedly,
produce non-standardized, differentiated products] have over their trademarked products is not
the power that makes an illegal monopoly.” 351 U.S. at 393.

the alleged monopolist operates (i.e., the relevant product market and/or the relevant
geographic market) in order to determine the extent to which he is actually capable of
exercising any meaningful price-controlling or competition-excluding power, or the extent
to which he has already done so.12
At least four views of economic markets provide some context to the “relevant
market” and subsequent monopolization determinations: free market, which holds that
(a) market forces produce the best allocation of resources, and (b) the non-anecdotal
evidence indicates no correlation between concentration and profits; centrist, which is
somewhat similar to the “free market” view that size and distribution don’t necessarily
signify the intensity of competition, but does believe that collusion is more likely in
concentrated markets; moderate structuralist, which emphasizes that the greater the
number of competitors in a market the more likely there will be downward pressure on
prices; and strict structuralist, which holds that competition is directly and inversely
related to concentration levels.13 The "bottom-line" goal of U.S. antitrust policy should
be "to encourage producers to make and sell better products at lower prices and pass those
savings on to consumers."14
The jointly issued Horizontal Merger Guidelines15 were promulgated in order to
inform the business community of the agencies’ (DOJ, FTC) governing philosophy and
“analytical framework” when they are reviewing the permissibility of proposed mergers.

12 United States v. E.I. duPont de Nemours & Co. (351 U.S. 377 (1956)) is considered a landmark
monopolization case. There, in order to determine whether duPont’s dominance in the
cellophane wrapping market amounted to unlawful “monopolization,” it was necessary for the
Court to define a product market that included, but was larger than, “cellophane wrapping” before
it could ultimately determine “whether [duPont] control[led] the price and competition in the
market for such part of trade or commerce as [it is] charged with monopolizing” (Id. at 392, i.e.,
whether there was significant enough competition from non-cellophane, flexible wrapping
materials to dilute duPont’s admitted monopoly in the cellophane wrapping market). The
monopoly enjoyed by duPont in the cellophane wrapping market was found not to amount to
unlawful monopolization of the market for flexible packaging materials: “... despite cellophane’s
advantages it has to meet competition from other materials in every one of its uses. ... We
conclude that cellophane’s interchangeability with the other materials mentioned suffices to make
it a part of this flexible packaging material market.” (351 U.S. at 398, 400).

15 See fn 2, supra. The Guidelines were issued in 1962 by the Antitrust Division, and revised in

1982 and 1984. They were substantially modified and issued jointly by DOJ and the FTC 1992,

and revised by the agencies in 1997. The 1984 version indicated that the Department would
consider foreign as well as domestic competition in determining the geographic market for the
products or services of a potential merger (§ 2.34). The 1992 version states that the “unifying
theme of the Guidelines is that mergers should not be permitted to create or enhance market
power or to facilitate its exercise” § 0.1). The 1997 revision dealt only with the agencies’
treatment of the so-called “efficiency defense”: a merger that is, on balance, anticompetitive, will
not generally be “saved” by claimed or actual efficiencies, nor likely be approved by the
reviewing agencies (§ 4). Although the Guidelines are not binding on either the Antitrust
Division or the FTC (or, for that matter, the courts), they are indicative of the agencies’ thinking
with respect to the competitive concerns inherent in all market transactions.

The “Purpose and Underlying Policy Assumptions” section of the Introduction states
unequivocally that “mergers should not be permitted to create or enhance market power
or to facilitate its exercise, but goes on to note that while “competitively harmful” mergers
will be challenged, there is a “larger universe of mergers that [is] either competitively
beneficial or neutral.”16 Emphasizing that distinction, the Assistant Attorney General in
charge of the Antitrust Division in 1998 testified:
Sometimes people complain about a merger solely based on its size. ... I want to
make clear[, however,] that antitrust analysis focuses on the specific competitive
harms that may be associated with a particular merger, not on its size in the abstract.
Thus, for example, a big merger may not be challenged because the merging parties
are not competitors or potential competitors of one another and the merger does not
raise any vertical antitrust issues. At the same time, we may challenge a smaller
merger that involves the only two firms that make a particular product. The key for
our review is whether the merger will harm consumers, not the sheer size of the17
corporate entities involved.
Two relatively recent cases clearly illustrate the antitrust enforcement agencies’
currently existing differentiation between the existence of monopoly power and active18
monopolization: the Department of Justice suit against Microsoft and the FTC’s
complaint against Intel.19 In Microsoft, the Antitrust Division stated that “Microsoft
possesses (and for several years has possessed) monopoly power in the market for
personal computer operating systems,”20 but filed its action not to challenge Microsoft’s
monopoly status, but rather, the company’s actions:
To protect its valuable Windows monopoly against ... potential competitive threats,
and to extend its operating system monopoly into other software markets, Microsoft
has engaged in a series of anticompetitive activities. Microsoft’s conduct includes
agreements tying other Microsoft software products to Microsoft’s Windows21
operating system; exclusionary agreements precluding companies or potential

21 Simply, “tying” is refusing to sell one product to a buyer unless the buyer agrees also to take

competitors from distributing, promoting, buying, or using products of Microsoft’s
software competitors or potential competitors; and exclusionary agreements restricting
the right of companies to provide services or resources to Microsoft’s software22
competitors or potential competitors.
The district court’s finding that Microsoft acted anticompetitively in violation of
section 2 by tying its Internet Explorer (IE) browser to its operating system, and thus per
se violated section 1 of the Sherman Act, was upheld in the United States Court of
Appeals for the District of Columbia.23 But, although the appeals court supported the
district court finding that Microsoft is, in fact, a monopolist, it nevertheless refused to find
that the bundling of IE with the operating system could, therefore, be characterized as a
per se violation. The court was willing to suspend judgment on the issue in light of the
dearth of case law addressing it, and the relative lack of actual experience with the
arrangements (“the poor fit between the separate-products test and the facts of this
case”),24 and so felt compelled to remand the per se finding to the district court for further
consideration in light of its opinion that the tying activity at issue could at most be
considered a violation of the antitrust laws because unreasonable under the Rule of25
The District Court determined that Microsoft had maintained a monopoly in the
market for [certain] operating systems in violation of § 2; attempted to gain a
monopoly in the market for internet browsers in violation of § 2; and illegally tied two
purportedly separate products, Windows and Internet Explorer ("IE"), in violation of
§ 1. ... [W]e affirm in part and reverse in part the District Court's judgment that
Microsoft violated § 2 of the Sherman Act by employing anticompetitive means to
maintain a monopoly in the operating system [OS] market; we reverse the District
Court's determination that Microsoft violated § 2 of the Sherman Act by illegally
attempting to monopolize the internet browser market; and we remand the District
Court's finding that Microsoft violated § 1 of the Sherman Act by unlawfully tying its

21 (...continued)
a designated second product (“you can’t buy X without Y”), thus precluding the buyer’s choice
concerning where to purchase each component, and foreclosing to other sellers a portion of the
market in the tied product. The established “test” for a tying violation first requires that there be
two separate products -- each, or either, capable of being purchased separately by a consumer,
but also a defendant with monopoly power in the market for the tying product, lack of choice for
the consumer, and foreclosure of a substantial volume of commerce. Tying is most generally
analyzed as a per se violation of the antitrust laws, although when a court has failed to find the
requisite “separate products,” a Rule of Reason analysis has been employed. See e.g., United
States v. Jerrold Electronics Corp., 187 F.Supp. 545 (E.D. Pa. 1960), aff’d per curiam, 365 U.S.
567 (1961); Broadcast Music, Inc. v. CRS, 441 U.S. 1 (1979); Jefferson Parish Hospital District
No. 2 v. Hyde, 466 U.S. 2 (1984). The effect of a patent on judicial analysis of an alleged tying
violation was the subject of a 2006 Supreme Court opinion, Illinois Tool Works Inc. v.
Independent Ink, Inc., 547 U.S. (2006). For a discussion of that case, see CRS Report
RS22421, “Antitrust Effect of Patent on Tying Product: Illinois Tool Works Inc. v. Independent
Ink, Inc.”

requested rehearing, denied by the court of appeals on August 2, 2001.

browser to its operating system. ... While every “business relationship” will in some
sense have unique features, some represent entire, novel categories of dealings. ... the
arrangement before us is an example of the latter, offering the first up-close look at
the technological integration of added functionality into software that serves as a
platform for third-party applications. There being no close parallel in prior antitrust
cases, simplistic application of per se tying rules carries a serious risk of harm.
Accordingly, we vacate the District Court’s finding of a per se tying violation and
remand the case. Plaintiffs [United States, various states] may on remand pursue their26
tying claim under the rule of reason.
On remand, the district court seemed to heed the appellate court findings concerning
the use of Microsoft’s lawful monopoly power in furtherance of unlawful
monopoliz ation.27
In the charges against Intel Corporation by the FTC, the Commission acted to
restrain the "pattern of conduct ... that violates Section 5 of the Federal Trade Commission
Act, 15 U.S.C. § 45,"28 and not because of Intel's acknowledged monopoly status.29
As a monopolist, Intel can compete by producing better, cheaper and more
attractive products. It cannot act to cement its monopoly power by preventing
other firms from challenging its dominance. Intel has acted illegally. It has used
its monopoly power to impede innovation and stifle competition [by denying
necessary technical information to certain customers in retaliation for their suits30
against Intel to enforce their (the customers') patents, allegedly infringed by Intel].
Some observers view the present enforcement posture as evidence of the flexibility
and workability of the federal antitrust laws, although it is certainly possible to disagree
with the way(s) in which the antitrust enforcement agencies have acted with respect to
particular instances of proposed mergers or vis-a-vis specific, alleged monopolists. Given
the existing rationale of the antitrust laws, however, it is difficult to disagree with their
policy of prohibiting only those transactions/activities which they believe do/will, in fact,
harm competition. On the other hand, Congress is free to re-examine the century-old
antitrust statutes in order to change their focus.
