Food and Drug Administration safety and efficacy standards impose extraordinary up-front Ramp;D costs on drug companies. On average, from the time a company first applies for a patent, it takes 12 to 15 years and 800 million before the first pill reaches the market. Obviously, if others were free to copy and sell that pill, having incurred none of those costs, there would be no incentive to make that kind of investment ‚ and none of the modern ‚miracle‚ drugs that investment produces. No one grows crops if others are free to harvest them. That‚s why the international hue and cry went up last month when the patent re-examination board of China‚s State Intellectual Property Office (SIPO) revoked Pfizer‚s China patent for Viagra. Because the effect was to allow domestic Chinese companies to begin copying and selling the drug themselves, the decision had all the appearances of outright theft ‚ from an American company, for the benefit of domestic companies.
