Opinion

ORDER GRANTING PLAINTIFFS’ MOTION FOR PARTIAL SUMMARY JUDGMENT AND DENYING DEFENDANT ZENITH’S MOTION FOR SUMMARY JUDGMENT

SEITZ, District Judge.

After defendant Zenith Goldline Pharmaceuticals, Inc. [“Zenith”] moved for *1343 summary judgment on the plaintiffs’ federal antitrust complaints [D.E. No. 77, Civ. No. 98-3125; D.E. No. 45, Civ. No. 99-1938], the Sherman Act Plaintiffs 1 sought a partial summary judgment [D.E. No. 21, Civ. No. 99-MDL-1817] that defendant Abbott Laboratories [“Abbott”] contracted with defendants Zenith and Geneva Pharmaceuticals, Inc. [“Geneva”], to secure the entire domestic market for prescription drugs containing terazosin hydrochloride in violation of section one of the Sherman Antitrust Act, 15 U.S.C. § 1. The undisputed facts in this case demonstrate that Abbott’s agreements with its horizontal competitors would tend to impair domestic competition and restrain the trade of tera-zosin hydrochloride products. American courts have long condemned such agreements as illegal per se under the Sherman Act. Accordingly, the Court will grant the requested partial summary judgment to the plaintiffs, deny defendant Zenith’s motion for summary judgment without prejudice, and allow the parties to conduct full discovery on the issues of causation and damages.

BACKGROUND

1. Stirrings of a Competitive Market for Terazosin Hydrochloride

Abbott developed terazosin hydrochloride for the treatment of hypertension and enlarged prostate and sought the Food and Drug Administration’s [“FDA”] approval to market the drug by filing a New Drug Application [“NDA”]. Pursuant to the Food, Drug, and Cosmetic Act, 21 U.S.C. §§ 301-91 [“FDCA”], FDA examined terazosin hydrochloride’s safety and efficacy and approved it for human consumption, publishing three of Abbott’s claimed patents in the publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” affectionately known as the “Orange Book.”

In 1987, Abbott began exclusively marketing terazosin hydrochloride under the trademark “Hytrin” in tablet and capsule forms. Hytrin has been lucrative for Abbott. According to the Federal Trade Commission, Hytrin generated $540 million in sales in 1998, accounting for more than twenty percent of Abbott’s net sales of pharmaceutical products in the United States. 2

Beginning in 1990, generic drug maker Geneva took steps to compete with Abbott by developing a generic terazosin hydrochloride drug that could contain different inactive ingredients and be sold without a brand name in tablet and capsule forms. Taking advantage of the “Hatch-Waxman Amendments” to FDCA that streamlined the evaluation process for proposed generic drugs, 3 Geneva applied for FDA approval by submitting four Abbreviated New Drug Applications [“ANDAs”] between 1993 and 1996. Geneva’s ANDAs relied on *1344 data concerning Hytrin’s safety and efficacy, asserted that the proposed generic drug was “bioequivalent” to Hytrin, and certified under paragraph IV of 21 U.S.C. § 355(j)(2)(A)(vii) that the proposed drug did not infringe any valid patent claimed by Abbott for Hytrin.

When Abbott received notice of Geneva’s “paragraph IV certifications” challenging its patents, it exercised its statutory right to sue Geneva within forty-five days for patent infringement under 21 U.S.C. § 355(j)(5)(B)(iii) by instituting several actions in the United States District Court for the Northern District of Illinois. By statute, these suits effectively prevented FDA from approving Geneva’s disputed ANDAs for 30 months unless Abbott’s Hytrin patents were declared “invalid or not infringed.” Id. § 355(j)(5)(B)(iii)(I).

The Hatch-Waxman Amendments to FDCA furnished a significant incentive for Geneva to raise the first challenge to Abbott’s Hytrin patents, namely, exclusive marketing rights to the first generic version of Hytrin for 180 days. Id. § 355(j)(5)(B)(iv). Under the “successful defense” regulation that FDA promulgated to implement this statutory incentive, however, Geneva needed to obtain a final decision of non-infringement from either the trial court or the Court of Appeals for the Federal Circuit in order to perfect its entitlement to the 180-day exclusive marketing period. See Abbreviated New Drug Application Regs., 54 Fed.Reg. 28,872, 28,-894 (July 10, 1989); Abbreviated New Drug Application Regs., Patent and Exclusivity Provisions, 59 Fed.Reg. 50,338, 50,-350-55 (Oct. 3, 1994). If another generic drpg maker, such as Zenith, challenged Abbott’s patents and successfully defended its ANDA first, Geneva would not be entitled to this statutory incentive. Zenith would be able to market the first generic terazosin hydrochloride drug, albeit without exclusive marketing rights to delay its competitors from entering the marketplace.

In June, 1994, Zenith joined the race to bring the first generic terazosin hydrochloride drug to market by filing an ANDA featuring a paragraph IV certification on one of Abbott’s Hytrin patents. (Zenith Mem., Oct. 22, 1999, Ex. 6, at 11.) Abbott brought two unsuccessful infringement suits against Zenith for infringement of this patent, which was not timely included in the Orange Book. See Abbott Labs. v. Zenith Labs., Inc., 934 F.Supp. 925, 939 (N.D.Ill.1995) (dismissing case and observing that Abbott retained right to sue Zenith for patent infringement “upon the commencement of marketing ... of the generic copy”). Abbott then submitted two additional patents to FDA for inclusion in the Orange Book, U.S. Patents 5,412,095 [“’095 patent”] and 5,504,207 [“ ’207 patent”]. In March, 1996, FDA informed Zenith that it would have to amend its ANDA to certify with respect to those patents. Zenith balked at amending its ANDA, however, because Abbott then could institute another infringement suit and trigger a new 30-month stay of FDA approval (absent an intervening judicial determination of non-infringement) of Zenith’s proposed generic tablet. On April 15, 1996, Zenith sued Abbott for improperly listing the ’095 and ’207 patents, and requested injunctive relief delisting them from the Orange Book. Abbott counterclaimed, alleging that Zenith had infringed those patents.

Later that month, on April 29, 1996, Geneva renewed its drive to market the first generic tablet and capsule versions of Hytrin by filing an ANDA featuring a new paragraph IV certification with respect to Abbott’s recently-listed ’207 patent. Abbott launched an. infringement action to stop Geneva’s new generic tablet proposal, but inexplicably failed to protest Geneva’s new generic capsule proposal. FDA con *1345
