*378 MEMORANDUM OPINION AND ORDER
Defendants Media Sciences International, Inc. and Media Sciences, Inc. (collectively, “MS”) bring antitrust counterclaims against plaintiff Xerox Corporation (“Xerox”) under Section 2 of the Sherman Act, 15 U.S.C. § 2 (2006). MS alleges that Xerox monopolized or attempted to monopolize the market for replacement solid ink sticks for use in Xerox phase change color printers. Xerox moves to dismiss the antitrust counterclaims pursuant to Fed.R.Civ.P. 12(b)(6) for failure to state a claim upon which relief can be granted. For the reasons that follow, Xerox’s motion is DENIED.
BACKGROUND
On June 23, 2006, Xerox filed a complaint against MS alleging that its manufacture, use, and sale of solid ink sticks for use in Xerox phase change color printers infringe multiple Xerox patents. On January 16, 2007, MS filed its Second Amended Answer, which contained (for the first time) a Fifth Counterclaim alleging an antitrust violation under Section 2 of the Sherman Act. On January 30, 2007, Xerox filed a motion to dismiss the Fifth Counterclaim, arguing, inter aha, that the allegations contained therein were conclusory. In its memorandum of law opposing Xerox’s motion, MS sought leave to again amend its answer, attaching a proposed Third Amended Answer that it suggested more fully alleged antitrust violations. Xerox then filed a memorandum of law responding to MS’s opposition, and opposing the motion to amend on the grounds that the amended counterclaims were subject to dismissal under Rule 12(b)(6) and thus amendment would be futile. Finally, MS filed a memorandum of law responding to these arguments.
The antitrust allegations, as set forth in the Fifth and Sixth Counterclaims of the proposed Third Amended Answer, are as follows: Xerox is the only seller of phase change color printers (also known as solid ink printers) in the United States. (Third Amended Answer (“TAA”) ¶ 61.) It is also the primary supplier of replacement solid ink sticks for such printers, with a market share of over 90%. (TAA ¶¶ 62, 66.) MS is the only other significant supplier of replacement color ink sticks, in direct competition with Xerox, and has been experiencing increasing ink stick sales. (TAA ¶¶ 54, 67.) These color ink sticks and Xerox phase change color printers are only compatible with one another; thus, consumables from other types of printers cannot be used with phase change color printers and replacement color ink sticks can not be used in any other type of printer, such as a laserjet or inkjet. (TAA ¶ 62.) The price of MS’s replacement solid ink sticks is affected only by price changes in the price of Xerox’s solid ink sticks. It is not affected by price changes in the price of consumables for other types of printers, phase change color printers, or any other type of printers. (TAA ¶ 63, 64.)
MS further alleges that in order to acquire and maintain its monopoly power in the market for replacement solid ink sticks, Xerox engaged in the following anticompetitive behavior. First, it altered the feed channels in its new phase change color printer to prevent MS from selling its (non-infringing) replacement solid ink sticks to users of this printer. (TAA ¶ 69(a).) Second, it pursued and received patent protection for the changes to the feed channels and the corresponding changes to replacement solid ink sticks, precluding MS from modifying its replacement solid ink sticks to make them compatible with the new phase change color printer. (TAA ¶ 69(b).) During prosecution of these patents and afterwards, Xe *379 rox modified all its other models of phase change color printers to utilize the new feed channels and discontinued (or intends to discontinue) those that do not, in order to have its patent cover the entire market of replacement solid ink sticks. (Id.) The only benefit to consumers of the feed channels and corresponding solid ink sticks— preventing the insertion of the wrong color of ink into the wrong channel — was already served by key plates in previous models of Xerox phase change color printers. (Id.) Third, Xerox disseminated false and disparaging statements about MS and has discouraged customers making service calls for their phase change color printers from using non-Xerox solid ink sticks. (TAA ¶ 69(c).) Finally, Xerox has offered loyalty rebates to those resellers, distributors, and wholesalers who agree not to sell MS’s replacement solid ink sticks. (TAA ¶ 69(d).) As a result of this conduct, MS alleges that Xerox has monopolized and attempted to monopolize the market for replacement solid ink sticks.
STANDARD OF REVIEW
In its opposition memorandum of law, MS moves to amend its answer. Fed. R.Civ.P. 15(a) provides: “a party may amend the party’s pleading only by leave of court ... and leave shall be freely given when justice so requires.” A Court should deny a motion to amend only for good reasons, such as “undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, [and] futility of amendment.”
Foman v. Davis,
When considering a motion to dismiss under Rule 12(b)(6), the Court “must accept as true the factual allegations in the complaint, and draw all reasonable inferences in favor of the plaintiff.”
Bolt Elec., Inc. v. City of New York,
The Court is generally limited to “the factual allegations in [the] complaint, documents attached to the complaint as an exhibit or incorporated in it by reference, matters of which judicial notice may be taken, or documents either in plaintiff’s] possession or of which plaintiff ] had knowledge and relied in bringing suit.”
Brass v. American Film Technologies, Inc.,
DISCUSSION
Section 2 of the Sherman Act makes it unlawful to “monopolize, or attempt to monopolize, or combine or conspire with any other person or persons, to monopolize any part of the trade or commerce among the several States.” 15 U.S.C. § 2. MS’s Fifth and Sixth Counterclaims allege that Xerox violated the Sherman Act by monopolizing or attempting to monopolize the market for replacement solid ink sticks. According to Xerox, MS’s antitrust counterclaims must be dismissed because they fail, as a matter of law, to allege: (1) a valid antitrust injury; (2) a valid relevant market; and (3) prohibited anticompetitive conduct. The Court will address these contentions seriatim.
1. Standing and Antitrust Injury
Private plaintiffs seeking to enforce Section 2 of the Sherman Act must satisfy the standing requirement of Sections 4 and 16 of the Clayton Act.
2
See Sunshine Cellular v. Vanguard Cellular Systems, Inc.,
Antitrust injury is “injury of the type the antitrust laws were intended to prevent and that flows from that which makes defendants’ acts unlawful.”
Brunswick Corp.,
MS alleges that as a result of Xerox’s conduct, “competition in the relevant market has been suppressed,” and MS “has sustained the type of injury that the antitrust laws were intended to prevent.” (TAA ¶¶ 70-71.) Xerox argues these allegations are insufficient because they fail to show an actual adverse effect on competition as a whole. (Xerox’s Mem. in Support of Mot. to Dismiss 16.) However, MS need not wait to make this claim until it is “actually ... driven from the market and competition is thereby lessened.”
Brunsivick
Corp.,
The first allegation of anticompetitive conduct is that Xerox redesigned its phase change color printers and patented the replacement solid ink sticks to preclude all competition from the market for replacement solid ink sticks. MS is confronted with a decision of whether to (1) produce the solid ink sticks, risking liability in the event a Court determines Xerox’s patents to be valid and infringed; or (2) cease production of solid ink sticks. As both the primary claims in this lawsuit and MS’s increasing ink sales indicate, MS chose the former strategy. Because MS did not halt production and sales of solid ink sticks, the most obvious actual injury it can allege based on Xerox’s conduct is the cost of defending against this litigation. The cost of defending against a non-frivolous patent lawsuit is hardly the type of injury that antitrust laws were intended to prevent. However, by this lawsuit, MS is threatened with being precluded entirely from the market for solid ink sticks.
(See
TAA ¶ 69(b) (Xerox’s conduct threatens to “exclud[e] lower-priced competitors, such as MS Inc., from the relevant market”).) One of two producers in the market will have been driven out and no competitors will be able to enter, offering consumers fewer choices and potentially higher prices. This threatened injury (of direct exclusion from the marketplace) is exactly the type that antitrust laws were designed to prevent and flows from the competition-reducing aspect of Xerox’s conduct.
4
See, e.g., C.V.R. Reddy M.B.B.S. v. Puma,
No. 06-cv-1283,
The second allegation of anti-competitive conduct is that “Xerox has disseminated false and disparaging statements.” (TAA ¶ 69(c).) Elaborating on the injury to itself, MS alleges that it “has suffered monetary damages through injury to its reputation caused by Xerox’s actions, and by customers lost as a result of those actions.” (TAA ¶ 58.) “Mere allegations of business disparagement are not the type of injuries to competition that the antitrust laws were designed to prevent.”
Re/Max Int’l v. Realty One,
The final allegation of anticompetitive conduct is Xerox’s “offering of loyalty rebates to its resellers, distributors, and wholesalers who agree not to sell MS Inc. replacement solid ink sticks.” (TAA ¶ 69(d).) MS claims to have been injured by being excluded from selling to certain retail outlets, thus reducing its potential sales. Further, such loyalty rebates have allegedly “reducefed] the supply of lower-price competing products,” which are excluded from “much of the market.”
(Id.)
Taking these allegations to be true, it is plausible that MS was unable to find an outlet to reach consumers desiring its product. While MS’s own loss of business is an insufficient allegation of antitrust injury, it is sufficient if it stems from conduct that prevents potential customers from obtaining a desired product.
Cf. National Assoc. of Pharmaceutical Mfrs., Inc. v. Ayerst Labs.,
“A showing of antitrust injury is necessary, but not always sufficient” to establish standing.
Cargill, Inc.,
II. Relevant Market
“In order to survive a motion to dismiss, a claim under Sections 1 and 2 of the Sherman Act must allege a relevant geographic and product market in which trade was unreasonably restrained or monopolized.”
Global Discount Travel Servs., LLC v. Trans World Airlines, Inc.,
Xerox does not dispute that that the relevant geographic market is the United States.
5
Thus, the dispute focuses on the relevant product market. “A relevant product market consists of ‘products that have reasonable interchangeability for the purposes for which they are pro
*384
duced — price, use and qualities considered.’ ”
PepsiCo, Inc. v. Coco-Cola Co.,
MS defines the relevant product market as the “sale of replacement solid ink sticks for use in Xerox phase change color printers.” (TAA ¶ 62.) MS then alleges that “replacement color ink sticks are not interchangeable with the consumables for any other brand of color printer, ... [nor are consumables for other types of color printers, such as inkjet cartridges for inkjet printers and toner cartridges for laser jet printers ... reasonably interchangeable with consumables for Xerox phase change color printers.” (Id.) From the view of an owner of a Xerox phase change color printer, the primary customer of replacement solid ink sticks, no other consumables are acceptable substitutes. 6 Solid ink sticks are, literally and technically, not interchangeable with other consumables. Thus, MS has defined a product market that is both plausible and bears a rational relationship to the rule of reasonable interchangeability.
Xerox argues that the Court should reject MS’s alleged product market because it is based on a single brand— replacement solid ink sticks for Xerox phase change color printers.
See Mathias v. Daily News, L.P.,
The relevant market for antitrust purposes is determined by the choices available to Kodak equipment users. Because service and parts for Kodak equipment are not interchangeable with other manufacturers’ service and parts, the relevant market from the Kodak equipment owner’s perspective is composed of only those companies that service Kodak machines. This Court’s pri- or cases support the proposition that in some instances one brand of a product can constitute a separate market.
Id.
at 481-82,
III. Monopolization
The elements of a monopolization claim under Section 2 of the Sherman Act are: “(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 superi- or product, business acumen, or historic accident.”
PepsiCo,
A. Monopoly Power
“Monopoly power, also referred to as market power is the power to control prices or exclude competition. It may be proven directly by evidence of the control of prices or the exclusion of competition, or it may be inferred from one firm’s large percentage share of the relevant market.” Tops Mkts.,
Inc. v. Quality Mkts., Inc.,
Xerox argues instead that even if it has a monopoly share of the market for replacement solid ink sticks, it cannot exert monopoly power because competition exists in the color printer market. More specifically, Xerox contends that it is unable to raise the price of its replacement solid ink sticks because the increased profits from doing so would be offset by a loss in profits from lower color printer sales. Essentially, Xerox asks the Court to consider color printers and their consumables to be a unified market for the purposes of monopoly power.
This exact question was again addressed in
Kodak.
The Court refused to adopt Kodak’s proposed “legal rule that equipment competition [in the primary market] precludes any finding of monopoly power in the derivative aftermarkets.”
Instead, the Court considered the facts in the record to determine whether it was possible to possess monopoly power in the aftermarket for parts and service.
Id.
at 467,
Drawing directly from the Supreme Court’s analysis, MS alleges that “purchasers could not arrive at an accurate ‘lifecycle price’ because ... the costs are high to acquire information about price, quality, [and] availability of products needed to operate the printer.” (TAA ¶ 65.) It further alleges that as a result of “the high *387 cost of switching from one printer to another after the initial purchase, ... consumers are ‘locked in’ by their purchase ... and will tolerate supra-competitive pricing of replacement solid color ink sticks.” (Id.) Xerox counters that consumers are not “locked in” because they did not “undergo years of expensive investment in a primary market” and that the allegations of the high costs of obtaining accurate “lifecycle pricing” are conclusory. (Xerox’s Combined Reply Mem. 14-15.) Xerox may ultimately be correct that because of the modest cost of color printers and the availability of information as to lifecycle costs, increases in the price of replacement solid ink sticks will reduce sales of Xerox phase change color printers to such an extent that it is economically unable to exert monopoly power. At the motion to dismiss stage, however, MS has adequately alleged that Xerox possesses monopoly power in the relevant market.
B. Anticompetitive Conduct
“The mere possession of monopoly power, and the concomitant charging of monopoly prices, is not only not unlawful; it is an important element of the free-market system.”
Verizon Comm’ns Inc. v. Trinko,
1. Redesign and Patenting
Xerox accuses MS of misconstruing the antitrust laws as prohibiting the introduction of new and redesigned products and the securing of patents on such products. Clearly, the development of superior products is “an essential element of lawful competition, ... [and] any firm, even a monopolist, may generally bring its products to market whenever and however it chooses.”
Berkey Photo, Inc. v. Eastman Kodak Co.,
MS alleges that Xerox’s purpose in redesigning all its phase change color printers and patenting the compatible replacement solid ink sticks was wholly predatory, to exclude MS from the market and foreclose all other competition, and not to improve the product. (TAA ¶ 69(a).) Supporting this contention, MS alleges that the only benefit to consumers of the redesigned channels, preventing the insertion of the wrong color ink into the wrong channel, was already served by key plates in former models. (TAA ¶ 69(b).)
In arguing that such conduct can be anticompetitive and the basis of an antitrust claim under § 2 of the Sherman Act, MS relies on the Federal Circuit’s decision
9
in
C.R. Bard, Inc. v. M3 Systems,
*388
Inc.,
In order to prevail on its claim of an antitrust violation based on Bard’s modification of its Biopty gun to prevent the use of competing replacement needles, M3 was required to provide that Bard made a change in its Biopty gun for predatory reasons, i.e., for the purpose of injuring competitors in the replacement needles market, rather than for improving the operations of the gun.
Id. at 1382. The Court found sufficient evidence for the jury to make that finding. The dissent accused the majority of holding “that changing and improving one’s proprietary product, ... if to a competitor’s potential disadvantage, is actionable under the Sherman Act.” Id. at 1370. It noted that the trial court did not give the jury an instruction that patent law expressly allowed a patent holder to exclude others without violating antitrust laws. 10
The Court is cognizant of the danger of opening up the courtroom doors to inquiries as to whether modifications that ex-elude competition truly constitute improvements or are otherwise justified.
See United States v. Microsoft Corp.,
To the contrary, several courts have found that product redesign, when it suppresses competition and is without other justification, can be violative of the antitrust laws.
See id.
at 65-67 (modifications to computer system to discourage distribution of rival internet browsers constituted anticompetitive conduct unless otherwise justified);
Abbott Labs. v. Teva Pharms. USA Inc.,
MS plausibly alleges that Xerox’s conduct was anticompetitive and not otherwise justified — Xerox’s new patent will cover the entire market for replacement solid ink sticks, precluding MS and any new entrants, and the patented redesign allegedly serves no benefit to consumers. Of course, if Xerox presents evidence that the modifications improved the product or otherwise served valid business reasons, then the Court or a jury may have to weigh these justifications against the alleged anticompetitive effect.
See HDC Med., Inc. v. Minntech Corp.,
2. Loyalty Rebates
Plaintiff alleges that Xerox offers “loyalty rebates” to its customers that agree not to sell plaintiffs solid ink sticks. (TAA ¶ 69(d).) Neither party has addressed the anticompetitive nature of loyalty rebates in their moving papers. While the conduct is not identical, loyalty rebates may be analogized to exclusive dealing arrangements, where a retailer agrees to purchase all of its requirements for a product from a single manufacturer. “Exclusive dealing can have adverse economic consequences by allowing one supplier of goods or services unreasonably to deprive other suppliers of a market for their goods.”
Jefferson Parish Hospital Dist. No. 2 v. Hyde,
To state a claim for exclusive dealing, MS “must allege as a threshold matter ... a substantial foreclosure of competition” in the relevant market.
Ford Piano Supply Co. v. Steinway & Sons,
No. 85 Civ. 1284(CSH),
MS alleges that Xerox offered loyalty rebates to its resellers, distributors, and wholesalers who agreed not to sell MS replacement solid ink sticks with the purpose and effect of reducing supply of lower price competing products in the market. (TAA ¶ 69(d).) These loyalty rebates, MS contends, “exclud[e] from much of the market” competing solid ink sticks sold by MS. (Id.) Taking the allegations to be true, the Court finds that MS has adequately alleged that Xerox’s loyalty rebates foreclosed a substantial share of the market, preventing MS from reaching the market with its replacement solid ink sticks, thereby employing anticompetitive conduct to achieve or maintain monopoly power. 11
CONCLUSION
For the foregoing reasons, Xerox’s motion to dismiss MS’s Fifth Counterclaim [29, 34] is DENIED. MS’s motion to file a Third Amended Answer is GRANTED. MS may proceed on its § 2 claims based on Xerox’s alleged redesign and patenting and its loyalty rebates.
SO ORDERED.
Notes
. Xerox also argues, in a cursory footnote at the end of its brief in opposition to the amendment, that granting leave to amend would cause it prejudice because the motion was made nine months after the case was filed. However, the motion to amend, prompted by Xerox's motion to dismiss, was filed prior to the established deadline for amendments of pleadings. The Court finds that MS was diligent in moving to amend its answer, and granting leave would cause no undue prejudice to Xerox.
. Section 4 of the Clayton Act provides: "[A]ny person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws may sue therefor” for treble damages. 15 U.S.C. § 15(a). Section 16 of the Clayton Act provides: "Any person, firm, corporation, or association shall be entitled to sue for and have injunctive relief ... against threatened loss or damage by a violation of the antitrust laws.” 15 U.S.C. § 26.
. Factors to consider in determining whether a plaintiff is a "proper party” to bring an antitrust action include: (1) the causal connection between the alleged antitrust violation and the harm to the plaintiff; (2) the existence of an improper motive; (3) whether the injury was of a type that Congress sought to redress with the antitrust laws; (4) the directness of the connection between the injury and alleged restraint in the relevant market; (5) the speculative nature of the damages; and (6) the risk of duplicative recoveries or complex apportionment of damages.
Balaklaw v. Lovett,
. In arguing against antitrust standing, Xerox assei'ts that "exclusion by a valid and enforceable patent” is not “the type of violation the antitrust laws are intended to prevent.” (Xerox’s Reply and Opp’n 9-10.) This argument is directed to whether Xerox's behavior constitutes prohibited anticompetitive conduct, a question that is considered infra. If it can, then the threat of exclusion of one of two competitors from the marketplace as a result of such conduct is clearly an injury of the type the antitrust laws were designed to prevent.
. Xerox notes that MS failed to allege a geographic market in its Second Amended Complaint. However, MS has corrected this deficiency in the proposed Third Amended Answer and now alleges that the relevant geographic market is the United States. (TAA ¶ 66.)
. Il is worth noting that MS is defining the relevant market based on reasonable interchangeability and without regard to the patents held by Xerox. Thus, cases cited by Xerox holding that “merely obtaining a patent for a product does not create a product market” are inapposite.
B.V. Optische,
. A typical single-brand product market would be one delineated by the single brand name product.
See, e.g., Global Discount Travel Servs., LLC,
. Xerox also argues that MS's definition of the relevant market warrants dismissal because Xerox competes with other companies in the color printer market, which is highly competitive. Color printers are clearly not acceptable substitutes for replacement solid ink slicks. Instead, Xerox appears to be arguing that the primary market for color printers and the aftermarket for consumables must be considered together. This argument is addressed infra in the context of whether Xerox can exert monopoly power over an aftermarket when it does not have monopoly power over the primary market.
. MS argues that Federal Circuit law is controlling on substantive issues of patent law implicated in the antitrust counterclaim.
See Nobelpharma AB v. Implant Innovations,
. Moreover, several judges noted in a concurrence to the denial of an en banc hearing that because the appellant did not challenge the jury instructions or argue that modification of a patented product within the scope of the claims can never constitute an antitrust violation,
Bard
did not establish or endorse a new antitrust theory.
C.R. Bard, Inc. v. M3 Sys., Inc.,
. MS also states a counterclaim for attempted monopolization based on the same allegedly anticompetitive conduct. "To recover for attempted monopolization, plaintiff must establish '(1) that the defendant has engaged in predatory or anticompetitive conduct with (2) a specific intent to monopolize and (3) a dangerous probability of achieving monopoly power.’ ”
