Earlier this week the Supreme Court heard oral arguments in FTC v. Actavis, in which the Federal Trade Commission is asserting that it is impermissible for a brand name drug company to pay a generic drug company to stay out of the market. Normally, such collusive behavior would constitute a clear violation of antitrust laws, because it reduces competition and thereby has the potential to raise prices to the detriment of consumers. But a complication arises in the case of branded and generic drugs because a patent is involved, giving the patent holder the lawful right to exclude competitors from the marketplace.
In a typical “reverse payment” case, the scenario unfolds as follows: First, the branded company enters the market with a new drug product that is covered by a patent. Some time later, but before the expiration of the patent, a generic drug company seeks to market a generic version of a drug, asserting that the patent is either invalid or not infringed (the assertion takes the form of a Paragraph IV certification, named for the section of the U.S. statute under which the certification arises, see 21 U.S.C. 355(j)(2)(A)(vii)(IV)). Rather than litigate the case to completion, however, the two firms settle, with the patent holder agreeing to pay the generic company to stay off the market until some future date, such as the date that the patent is set to expire. The “monopoly” profits are thus shared between the two companies, to the detriment of consumers.
Defenders of reverse payment settlements argue that such agreements should be legal so long as they are “within the scope of the patent,” that is, so long as the restrictive agreement does not extend beyond the patent expiration date (see, e.g., Edward Stewart, Skepticism from the Court in Drug Case, N.Y. Times, Mar. 25, 2013). The fundamental weakness of this argument—and what the N.Y. Times article does not mention—is that many drug patents (73% according to a 2002 government report (see page vi)) turn out to be invalid, not infringed, or otherwise insufficient when litigated in court. If many drug patents would be invalid or not infringed if litigated to conclusion, then the actual “scope of the patent” would be less than its nominal term would suggest, and the high cost borne by consumers would be greater than the patent law contemplates.
