Second Circuit Affirms
Tamoxifen Dismissal
On November 2, 2005, the United States Court of “authorized generic,” particularly in the context of the Appeals for the Second Circuit affirmed the dismissal of Supreme Court’s recent request to the Department of Justice complaints filed by consumers and others in civil antitrust for its views on a petition for certiorari filed by the Federal litigation relating to anti-cancer drug, Tamoxifen. In re Trade Commission from the decision of the Eleventh Circuit Tamoxifen Citrate Antitrust Litigation, No. 03-7641 (2d in Schering Plough et al. v. FTC, 403 F.3d 1056 (2005).1 Cir., November 2, 2005). The complaints asserted that Read most broadly, the decision of the Second Circuit held AstraZeneca and Barr Laboratories violated federal and “that absent an extension of the monopoly [granted by a state antitrust laws when they settled Astra’s patent litiga- patent] beyond the patent’s scope…and absent fraud…” a tion against Barr.

Ed. 2d 48 (1982), should be applied in cases involving antitrust attacks on settlements of Hatch-Waxman patent litigation. Instead, Schering-Plough found that “the proper analysis of antitrust liability requires an examination of: (1) the scope of the exclusionary poten- tial of the patent; (2) the extent to which the agreements exceed that scope; and (3) the resulting anticompetitive effects.” See also Valley Drug Co. v. Geneva Pharms., 344 F.3d 1294, 1303-04 (11th Cir. 2003). Applying that analysis, the court vacated a cease and desist order of the Federal Trade Commission prohibiting Schering-Plough and Upsher-Smith Laboratories from “being parties to any agreement settling a patent infringement lawsuit, in which a generic manufacturer either (1) receives anything of value; and (2) agrees to suspend research, development, manufacture, marketing, or sales of its product for any period of time.” Schering Plough, 403 F.3d at 1056. In proceedings before the FTC, the staff alleged that the settlement agreements were “veiled attempts to disguise a quid pro quo arrangement aimed at preserving Schering’s monopoly in the potassium chloride supplement market.” The Commission applied the “rule of reason” and found “that the coupling of reverse payments with an agreement by the generics not to ‘enter the market before a particular date, “raise[d] a red flag that distinguishes this particular litigation settlement from most other patent settlements, and man- dates a further inquiry.’” Schering-Plough, 403 F.3d at 1068. In its judgment, the Commission “prohibited settlements” under which a manufacturer of a generic pharmaceutical product “receives anything of value [from a patent holder] and agrees to defer its own research, development, production or sales activities.” The Commission “carved out one arbitrary exception … beyond a ‘simple compromise’ to the entry date [i.e., the date on which a generic product might first be marketed], if payments can be linked to litigation costs (not to exceed $2 million), and the Commission is notified of the settlement, then the parties need not worry about a later antitrust attack.” Id., 403 F.3d at 1062. The appellate court noted that, in proceedings before the Commission, there had been “no allegation that the [relevant] patent itself is invalid or that the result- ing infringement suits against Upsher and ESI were ‘shams.’” The Commission, which found the settlement anti-competitive, petitioned the Supreme Court to review the vacatur The Tamoxifen court disagreed with the approach taken by the FTC.

While the Astra-Barr patent litigation was Barr’s agreement to change its ANDA filing.

Whether the courts apply the rule of reason, a per se approach, or some other approach, it would seem that in every case, the determination depended, either explicitly or implicitly, on the court’s assessment whether particular provisions of a settlement agreement went “beyond the limited monopoly which is granted” by a patent.

In Valley Drug Co. v. Geneva Pharms., Inc., 344 F.3d 1294 (11th Cir. 2003), for example, the Eleventh Circuit reversed a district court’s finding, on a motion for summary judgment, that a patent settlement that involved a “reverse payment” was per se illegal. In re Terazosin Hydrochloride Antitrust Litig., 164 F. Supp. 2d 1340, 1345–46 (S.D. Fla. 2000). In doing so, the Eleventh Circuit remanded the case for further proceedings, and gave the following instruction to the district court: The appropriate analysis on remand will likely require an identification of the protection afforded by the patents and the relevant law and consideration of the extent to which the Agreements reflect a reasonable implementation of these. Appellants, for example, contend that certain provisions of the Geneva Agreement are analogous to a consensu- al preliminary injunction and stay of judgment pending appeal. To evaluate this claim, the provisions of this Agreement should be compared to the protections afforded by the preliminary injunction and stay mechanisms and considered in light of the likelihood of Abbott’s obtaining such protections. Cf. Hovenkamp at p. 2046 (‘some care must be taken to ensure that . . . the settlement . . . is not more anticompetitive than a likely outcome of the litigation’).

6 Judge Pooler continued: “Of course, in my view, plaintiffs need not plead or prove sham or objectively baseless litigation. But, in addition, the majority’s discussion of the later litigation appears to violate its own acknowledgment of the basic principle that “the reasonableness of agreements under the antitrust laws are to be judged at the time they are entered into.” Majority op. at 35 (quoting Valley Drug Co. v. Geneva Pharms., Inc., 344 F.3d 1294, 1306 (11th Cir. 2003) (citing, inter alia, SCM Corp., 645 F.2d at 1207)). At the time Zeneca and Barr settled the appeal, the existing facts made it fairly likely, if not certain, that Barr would prevail. Judge Broderick had judged the crediblity of the witnesses and found that Zeneca willfully withheld information from the FDA. That finding is quintessentially factual. Thus, the Federal Circuit could have set it aside only for clear error. Fed. R.
Civ. P. 52(a). Without the record, I cannot say that the Federal Circuit would have been required to affirm, but, as I am sure the majority will concede, it is the rare case in which an appellate court sets aside a trial court’s credibility findings. Had Barr prevailed, on appeal, as I expect it would have, Zeneca would have been estopped from asserting the validity of its patent in any subsequent litigation. Therefore, there is a certain unfairness in using the subsequent litigation, which would not have existed had Barr prevailed on appeal, to demonstrate that plaintiffs cannot establish that Barr would have prevailed on appeal.” In re Tamoxifen Citrate Antitrust Litigation, No. 03-7641 (Pooler, dissenting), at 94–95.

Ed. 2d 626 (1965). “Because we think that an agreement to time the deploy- ment of the exclusivity period to extend a patent’s monopoly power might well constitute anticompetitive action outside the scope of a valid patent,” the Second Circuit said, “we decline to rest our conclusion on the ground of Noerr-Pennington immunity.” Op. at 64–65.
9 The Second Circuit divided its analysis into three different time segments, holding that “the plaintiffs could not have suffered any antitrust injury with regard to an exclusiv- ity period for Barr from the time the defendants signed the Settlement Agreement until the time the regulations were changed in 1997–1998,” because, “[d]uring that period, as far as all parties were concerned, the Settlement Agreement had indeed “cleared the field” so that other generic challengers could enter the market.” The plaintiffs suffered “no antitrust injury from the time the ‘successful defense’ requirement was eliminated until, in 2000, the FDA rejected Barr’s claim to the exclusivity period, because the other ANDA filers with a paragraph IV certification ultimately lost their infringement suits against Zeneca.” Finally, the court said, “there is clearly no antitrust injury with regard to Barr’s use of the exclusivity period after the FDA rejected Barr’s claim to the exclusivity period in 2000.” From that time on, the court concluded, “no one could have thought that Barr had a claim to an exclusivity period. Any injury suffered by the plaintiffs arose from Zeneca’s patent monopoly, which remained valid until its expiration in 2002, after which other generic manufacturers did, in fact, enter the market.” Op. at 69–70.

It would seem that, as viewed by the Second Circuit, all such settlements must be viewed under the “rule of reason,” and that “reverse payments” of almost any size may be permis- sible, so long as they may be later demonstrated to be ration- ally related to the prospective profits that might have been earned by the patent owner (or the generic manufacturer) absent a settlement. It would also seem that, under the Second Circuit’s analysis, so long as a settlement does not on its face create a “bottleneck” to entry in the market by other generic manufacturers, it will not be condemned under the antitrust laws, even if the effect of an “authorized gener- ic” relationship between a patent owner and a generic com- petitor would be to delay entry until after a patent’s expira- tion, because the “authorized generic” settlor has no incen- tive to begin manufacturing its own generic product until
