This case presents the issue of whether a condominium developer’s sale of condominium units subject to two-year management contracts with an unaffiliated company constitutes an unlawful tie-in pursuant to section one of the Sherman Act. The district court dismissed with prejudice the plaintiff condominium associations’ Sherman Act count for failure to state a claim. The court also dismissed the plaintiffs’ remaining counts, brought under state law theories, without prejudice for want of subject matter jurisdiction. On appeal, we affirm the decision of the district court.
I.
In early 1979, the defendants First Condominium Development Company and Eagle II (the “Condominium Developers”) purchased and converted Carl Sandburg Village from rental apartments to condominium units. The Condominium Developers proceeded to market and sell condominium units in four of the buildings of Carl Sandburg Village to individual members of the plaintiff class. When the buildings were converted, about eighty percent of the tenants in the buildings purchased their respective units.
During the conversion process, the Condominium Developers established the plaintiff Carl Sandburg Village Condominium Associations Numbers 1 and 2 (the “Condominium Associations”) in order to manage and maintain the property’s common elements. On July 13,1979, the Condominium Associations, under the direction of the Condominium Developers, consented to be parties to condominium management agreements with co-defendant Arthur Rubloff and Company (“Rubloff”). Rubloff had been managing the buildings since 1965 when they were first built. The individual unit owners of the Condominium Associations were indirectly subject to the condominium management agreements with Rubloff by virtue of their status as members of the Condominium Associations. The management agreements appointed Rubloff as the managing agent for two years and gave the Condominium Associations the right to terminate the management agreements upon thirty days’ notice if Rubloff did not meet its obligations under the agreements. As compensation for these services, Rubloff was to receive a fee computed and payable monthly in the amount of $5.25 per occupied condominium unit.
On September 16, 1982, the Condominium Associations and their individual members sued the Condominium Developers, *206 Rubloff, and Rubloff s resident manager in a nine-count complaint, seeking treble damages of over $15 million and such other relief as the court deemed proper. In Count I, the plaintiffs alleged that the defendants agreed and conspired to tie the sale of Rubloff management services to the sale of condominium units at Carl Sandburg Village in violation of section 1 of the Sherman Act. 15 U.S.C. § 1 (1982). The plaintiffs alleged that the conspiracy to tie management services to condominium units had the effect of reducing competition, causing plaintiffs to incur excessive fees, and perpetuating Rubloff s control of management services for an unreasonable period of time. This tie-in purportedly precluded the plaintiffs from selecting an independent management service at a lower cost. The plaintiffs also alleged various state claims in counts II through IX for violation of the Illinois Antitrust Act by virtue of the tie-in, for breach of fiduciary duty in failing to disclose defects in the buildings, for negligent misrepresentation, for violation of the Chicago Municipal Code and Illinois Consumer Fraud and Deceptive Practices Act, for negligent construction, for breach of contract, and for breach of express and implied warranties of workmanship.
In dismissing plaintiffs’ count I tying claim with prejudice, the district court found that the Condominium Developers as sellers of the tying product (condominium units) did not have a sufficient economic interest in the sale of the tied product (management services) to support a tying claim.
Carl Sandburg Village Condominium Association No. 1 v. First Condominium Development Co.,
On appeal, the plaintiffs claim that the district court assumed the resolution of factual issues and erroneously dismissed plaintiffs’ tie-in claim and that the court erroneously ruled on the pleadings that there was no rule of reason violation alleged by the plaintiffs. We will address each of these claims in turn below. 2
*207 II.
A. Dismissal for Want of Economic Interest in the Alleged Tying Arrangement
Following the filing of the complaint by the Condominium Associations, the Condominium Developers and Rubloff filed a motion to dismiss or for summary judgment. The district court held the defendants’ motion for summary judgment in abeyance and issued its opinion dealing with the motion to dismiss. We are asked to decide whether it was proper for the district court to dismiss the Condominium Associations’ complaint for failure to state a claim.
According to rule 12(b)(6) of the Federal Rules of Civil Procedure, a defendant may make a motion to dismiss asserting a failure by the plaintiff to state a claim upon which relief can be granted. In interpreting this rule, the Supreme Court has held that “a complaint should not be dismissed for failure to state a claim unless it appears beyond doubt that the plaintiff can prove no set of facts in support of his claim which would entitle him to relief.”
Conley v. Gibson,
The Supreme Court has defined a tying arrangement as an agreement by one party to sell a product (the tying product) to another on the condition that the buyer also purchase a different product (the tied product).
Northern Pacific Railway Co. v. United States,
In the usual tying arrangement, it is not difficult to establish the economic interest element because the seller of the tying product is also the seller of the tied product.
Robert’s Waikiki U-Drive, Inc. v. Budget Rent-A-Car Systems, Inc.,
In the present case, the district court held that the Condominium Associations had not alleged the requisite economic interest on the part of the tying sellers of condominium units in the management services (tied product) market. The district court noted that the case law clearly differentiates between cases where the tying and tied product are sold by the same seller and cases where the tying and tied products are sold by different, unaffiliated sellers. 3 In the latter case, the district court held that a plaintiff would have to allege that the seller of the tying product received a commission or rebate in order to establish a claim of illegal tying. The court concluded that the economic interest requirement had not been met in this case because the Condominium Associations had failed to allege that the Condominium Developers (tying sellers) had participated in the profits of Rubloff (tied seller) or in the market for management services. We agree with the district court’s conclusion that the Condominium Associations have failed to state a claim of per se illegal tying.
*209
In their complaint, the Condominium Associations alleged that Rubloff (tied seller) conferred an economic benefit upon the Condominium Developers (tying sellers) by concealing defects in the condominium development, thereby permitting the Condominium Developers to sell condominium units quickly at inflated prices without having to make the necessary repairs. The Condominium Associations claimed that this concealment of defects, which resulted in economic benefit to the Condominium Developers, could be analogized to a kickback, rebate, or commission. We reject this analogy because a tying seller’s increased sales and efficiency as a result of selling two products as a package do not show the tying seller’s economic interest in the tied product market. For example, in
Rodrigue v. Chrysler Corp.,
In addition, counsel for the Condominium Associations argued to this court that the economic interest requirement might be met as a result of certain checks which were made out to Rubloff (tied seller) by the Condominium Developers (tying sellers). Although the economic interest is flowing in the wrong direction in that situation (from tying seller to tied seller rather than from tied seller to tying seller), counsel for the Condominium Associations argued that the amount of the check might reflect a discount in the customary price of management services, thereby revealing an economic interest on the part of the Condominium Developers (tying sellers) in the management services (tied product) market. We acknowledge the fact that it might be difficult for a plaintiff to allege the economic interest element in a case of secret rebates or discounts where the plaintiff has not had the benefit of discovery. However, in the present case, the Condominium Associations were allowed to proceed with discovery by an order of the district court dated April 12, 1983. Thus, in addition to not even alleging an economic interest in their complaint, the plaintiffs failed to establish any economic interest following nearly one year of discovery proceedings. 4 As counsel for Rubloff argued before this court, all of plaintiffs’ discovery requests concerning any alleged economic interest were answered, and the defendants produced thousands of documents pursuant to plaintiffs’ requests. In sum, since the Condominium Associations have failed to state either direct or inferential allegations regarding the material elements necessary to state a per se violation of the antitrust laws, we affirm the district court’s dismissal of the illegal tying claim for failure to state a claim under rule 12(b)(6).
B. Dismissal for Failure to State a Rule of Reason Violation
In its first opinion of July 22, 1983, the district court focused on the Condomini *210 um Associations’ failure to allege any economic interest of the Condominium Developers in the management services market. In its second opinion of March 9, 1984, following a motion to reconsider by the plaintiffs, the district court addressed the Condominium Associations’ allegations under the rule of reason, having previously found that the plaintiffs did not state a per se illegal tying claim. 5 The district court found that the Condominium Associations had not stated a claim under the rule of reason because the conduct alleged did not involve an individual using its market power to alter the competitive structure of the market for management services nor an individual using its power in one market to squeeze a profit out of a second market. The district court concluded that the alleged scheme to conceal faults from purchasers did not implicate the type of conduct with which the antitrust laws were concerned.
According to the Supreme Court, a plaintiff’s failure to state a
per se
illegal antitrust claim does not necessarily prove fatal to his case if he can state a claim under the rule of reason.
Fortner Enterprises, Inc. v. United States Steel Corp.,
In monitoring the use of tie-ins, the goal of the antitrust laws in the tying context is to prevent the economically harmful effects of tie-ins in cases where a seller’s power in the market for the tying product is used to create additional power in the market for the tied product.
Jefferson Parish Hospital District No. 2 v. Hyde,
— U.S.-,
In conclusion, the district court’s dismissal with prejudice of the Condominium Associations’ complaint for failure to state a claim under the federal antitrust laws is affirmed. The district court’s dismissal without prejudice of the Condominium Associations’ remaining claims for lack of subject matter jurisdiction is also affirmed.
Notes
. We note that the Condominium Associations argue that the district court erred in failing to grant them leave to amend their antitrust count. However, the plaintiffs never sought leave to amend their complaint and do not indicate how they would amend their complaint to allege the economic interest element if granted leave. According to rule 15(a) of the Federal Rules of Civil Procedure, a party may amend his pleading after a responsive pleading is served only by leave of court or by written consent of the adverse party. Such leave to amend should be freely given when justice so requires. Fed.R. Civ.P. 15(a). We hold that the district court did not abuse its discretion in denying leave to amend because such leave was never requested.
See Coates v. Illinois State Bd. of Educ.,
. The Condominium Developers also argued in their motion to dismiss that the condominium units and the management services were a single product, so that the Condominium Associations had not alleged the existence of a tying arrangement between two distinct products. Since it found that the plaintiffs had not alleged the requisite economic interest element, the district court did not address the issue of separate products. Because we affirm on economic interest grounds, we similarly decline to discuss the separate products issue. We note, however, that this circuit has held that only one product is involved in the sale of condominium units subject to a management contract of reasonable duration.
Johnson v. Nationwide Industries, Inc.,
. In its first opinion of July 22, 1983, the district court noted that although the plaintiffs had drafted their complaint in a manner emphasizing a connection between Rubloff and the original developers of Carl Sandburg Village, the plaintiffs did not argue in their brief against the defendants' motion for dismissal that the tying and tied products should be deemed to be sold by affiliated entities.
Carl Sandburg Village Condominium Association No. 1 v. First Condominium Development Co.,
. Following the district court’s first opinion issued on July 22, 1983, the plaintiffs made a motion to reconsider and discovery continued until the court’s second opinion dated March 9, 1984.
. Over the years, the courts have held that certain types of contractual agreements should be deemed unreasonable as a matter of law and thus
per se
illegal.
