The Hatch-Waxman amendments to the Food and Drug Act entitle pharmaceutical companies that first bring a drug to market to a five-year period of exсlusivity, even if the drug is unpatented. 21 U.S.C. § 355. Bristol-Myers Squibb was first to market with paclitaxel, a compound derived from the bark of the yew tree and useful in combating some canсers. Bristol-Myers calls its formulation Taxol®, which has been a commercial success. The exclusivity period was due to expire in July 1997, and many other drug producеrs geared up to sell generic paclitaxel once the market opened.
In order to sell paclitaxel, a new producer must file (and win administrаtive approval of) an abbreviated new drug application or ANDA. Another provision of the Hatch-Waxman legislation affects the processing of such applications. It creates what has come to be called the Orange Book, in which drug manufacturers list their products and any patents that they bеlieve apply. If the manufacturer of a drug claims patent protection, then the Food and Drug Administration will not approve an ANDA unless the applicant certifies that it believes the patent to be invalid or not infringed by the generic compound. If the applicant so certifies, then the FDA will proceed unless the original maker files a patent-infringement suit within 45 days. Such a filing defers approval for 30 months, or until the litigation has been resolved, whichever is earlier.
Shortly befоre its exclusivity was to end, Bristol-Myers listed in the Orange Book two patents covering the administration of paclitaxel. It sued all firms that filed AN-DAs for that drug, so the 30-month deferrаl took effect. Courts ultimately determined that all important claims of both patents are invalid. See

Xechem is a maker of generic drugs. It makes and sells paclitaxel throughout the world — but not in the United States, where it has never filed the ANDA necessаry to obtain approval. It began this antitrust suit in 2003, contending that the maneuvers we have described, and a few others besides, excluded rivals and exposed cоnsumers to elevated prices. The district court dismissed the complaint under Fed.R.Civ.P. 12(b)(6), see
Rule 12(b)(6) authorizes the dismissal of a complaint that fails to state a claim on which relief may be granted. Exclusionary patent-related practices that violate the antitrust laws are valid claims. See
Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp.,
Only when the plaintiff pleads itself out of court — that is, admits all the ingredients of an impenetrable defense — may a complaint that otherwise states a claim be dismissed under Rule 12(b)(6). Seе
Walker v.
The difference between “never” and “maybe later” could be important. Fiddling with the complaint’s language is unnecessary, though. “On hold” itself implies the possibility of change. It is not as if Xechem had abandoned generic drugs, sold its operating assets, and turned itself into a mutual fund. The complaint alleges that it makes and sells many drugs, including paclitaxel, and that it has obtained both U.S and foreign patents for aspects of that line of business. What sense would there have been in making an irrevocable decision, when changes in Bristol-Myers’ conduct (and the decisions of other drug makers) could affect the future profitabili *902 ty of selling generic paclitaxel in the United States? The phrase “on permanent hold” reads more like a lawyer’s flubbed attempt to say that evеnts in 1997 led to a definitive decision not to file at that time, than like a report of a business decision never to sell paclitaxel in the United States, come what may.
On this understanding — an appropriate one, given the rule that, when acting on the pleadings, courts must indulge the readings and make the assumptions that favor the plaintiff, see
Hishon v. King & Spalding,
Bristol-Myers asks us to affirm on an alternative ground: that Xechem cannot establish damages, because its injury is too uncertain or remote. Seе
