On Petition for Review of an Order of the Federal Trade Commission

FTC Docket No. 9373

Before Southwick, Costa, and Duncan, Circuit Judges. Gregg Costa, Circuit Judge:

Normally, when lawsuits settle the defendant pays the plaintiff. That makes sense as the defendant is the party accused of wrongdoing.

But when a generic drug is poised to enter the market and threaten the monopoly enjoyed by a brand-name pharmaceutical, federal law can incentivize a different type of settlement. The Hatch-Waxman Act delays the entry of the generic drug if the brand-drug manufacturer files a patent infringement suit against the generic. Those patent suits are sometimes settled with the brand-drug plaintiff paying the allegedly-infringing generic.

No. 19-60394

In return for the payment, the generic agrees to delay its market entry beyond the date when the FDA would allow it to compete. The result is an extension of the brand drug’s monopoly.

Given the counterintuitive flow of money in this scenario—to, rather than from, the alleged wrongdoer—such deals are called “reverse payment settlements.” The Supreme Court has held that these settlements that extend the brand drug’s monopoly can have anticompetitive effects that violate the antitrust laws. FTC v. Actavis, 570 U.S. 136, 158 (2013). Reverse payment settlements, however, are not automatically invalid; they are subject to the rule of reason. Id. at 159.

In its first post-Actavis reverse payment case, the Federal Trade Commission charged Impax Laboratories with antitrust violations for accepting payments ultimately worth more than $100 million to delay the entry of its generic drug for more than two years. The resulting administrative hearing included testimony from 37 witnesses and over 1,200 exhibits. Based on that record, the Commission conducted a rule-of-reason analysis and unanimously concluded that Impax violated antitrust law.

On appeal, we face a narrower task: determining whether the Commission committed any legal errors and whether substantial evidence supported its factual findings. Concluding that the Commission’s ruling passes muster on both fronts, we DENY the petition for review.

I. A.

Anyone who buys pharmaceuticals knows that generic drugs are cheaper than their brand counterparts. The first generic to enter the market typically costs 10 to 25 percent less than the branded drug; those discounts grow to between 50 and 80 percent once other generics enter.

No. 19-60394

To bring competition to the drug market, the Hatch-Waxman Act promotes entry for these generics. Actavis, 570 U.S. at 142. Rather than undergoing the lengthy and costly approval process that a new drug faces, generics can file an Abbreviated New Drug Application with the Food and Drug Administration. Id. at 142; 21 U.S.C. § 355(j). If the generic drug is biologically equivalent to a brand drug the FDA has already approved, then the generic can essentially “piggy-back on the pioneer’s approval efforts.” Actavis, 570 U.S. at 142; 21 U.S.C. § 355(j)(2)(A)(i)–(iv). The Act offers an additional carrot to the first generic applicant: it can market its generic drug for 180 days without competition from any other generic manufacturer. Actavis, 570 U.S. at 143–44; 21 U.S.C. § 355(j)(5)(B)(iv). During this period of exclusivity, the newly approved generic only faces competition from the brand drug or a generic sold by the brand manufacturer. Actavis, 570 U.S. at 143–44. In effect, the statute allows a duopoly during those 180 days. A firstto -file generic often realizes most of its profits, potentially “several hundred million dollars,” during this initial six-month period. Id. at 143 (quoting C. Scott Hemphill, Paying for Delay: Pharmaceutical Patent Settlement as a Regulatory Design Problem, 81 N.Y.U. L. Rev. 1553, 1579 (2006)).

Generic entry is not so easy when there is a patent for the brand drug.

The Hatch-Waxman Act also addresses this common situation. If the brand manufacturer asserts a patent in its initial drug application, then the generic manufacturer must certify in its application that the patent is invalid or that its drug will not infringe the patent. 21 U.S.C. § 355(j)(2)(A)(vii)(IV). If the brand manufacturer disagrees (it likely will), it may file a patent infringement suit. 35 U.S.C. § 271(e)(2)(A). And if it does so within 45 days, the FDA is stayed from approving the generic application until either 30 months have passed or the patent litigation concludes. 21 U.S.C. § 355(j)(5)(B)(iii); see also Actavis, 570 U.S. at 143 (describing these procedures). This delay for the first generic’s entry also postpones the potential entry of other generics.

No. 19-60394

They must wait for the same 30-month stay and then for the expiration of the first generic’s 6-month exclusivity period before entering the market.

What happens if the patent suit against the first generic settles? The brand manufacturer no longer faces an immediate threat of competition from new generic entrants. The 30-month statutory stay restarts if the brand maker brings a patent suit against another generic that wishes to enter the market. Actavis, 570 U.S. at 155 (citing 21 U.S.C. § 355(j)(5)(B)(iii)). Plus, any subsequent generic is not entitled to the exclusivity period. Id. That greatly reduces the potential benefit of challenging the brand maker’s patent. Id. (noting that subsequent generics “stand to win significantly less than the first if they bring a successful” challenge to the patent).

These features of the Hatch-Waxman Act—the period of exclusivity for the first generic; the 30-month stay of the generic’s FDA application when the brand maker sues for infringement; and the reduced incentive a subsequent generic has to challenge the brand maker’s patent—can lead the brand maker to pay large sums for delaying entry of the first generic maker. Actavis, 570 U.S. at 155 (recognizing that these Hatch-Waxman “features together mean that a reverse payment settlement with the first filer . . . ‘removes from consideration the most motivated challenger, and the one closest to introducing competition” (quoting Hemphill, Paying for Delay, supra, at 1586)).

B.

The facts of this case show those incentives in action. The drug at issue is a type of oxymorphone, which is an opioid. Endo, the brand-name drug maker in this case, started selling an extended-release formulation of oxymorphone called Opana ER in 2006. An extended-release pain reliever provides medication to the bloodstream over several hours, as opposed to

No. 19-60394

immediate-release opioids which are short-acting. When it entered the market, Opana ER was the only extended-release version of oxymorphone.

In late 2007, Impax filed the first application to market generic extended-release oxymorphone. The application did not result in prompt approval of the generic, however, because Endo held patents for Opana ER that would not expire until 2013. Endo sued Impax for patent infringement in January 2008, delaying any FDA approval of the generic for 30 months— until June 2010—unless the litigation concluded earlier.

Early settlement talks failed, with Endo rejecting Impax’s proposed entry dates of January 2011, July 2011, December 2011, or January 2012.

The June 2010 expiration of the Hatch-Waxman stay loomed.

Delaying Impax’s entry beyond the stay period would save Endo millions. Endo had projected that generic entry would cut Opana ER sales by 85 percent within three months and cost it $100 million in revenue within six months.
