Thepharmaceutical industry argues that because new drugs will not be developed unless heavy development costs can be recouped in later sales, the current 20 years of protection provided by patents should be extended in the case of newly developed drugs. However, in other industries new-product development continues despite high development costs, a fact that indicates that the extension is unnecessary.
Which of the following, if true, most strongly supports thepharmaceutical industry's argument against the challenge made above?
(A) No industries other than thepharmaceutical industry have asked for an extension of the 20-year limit on patent protection. (B) Clinical trials of new drugs, which occur after the patent is granted and before the new drug can be marketed, often now take as long as 10 years to complete. (C) There are several industries in which the ratio of research and development costs to revenues is higher than it is in thepharmaceutical industry. (D) An existing patent for a drug does not legally prevent pharmaceutical companies from bringing to market alternative drugs, provided they are sufficiently dissimilar to the patented drug. (E) Much recent industrial innovation has occurred in products--example, in the computer and electronics industries--which patent protection is often very ineffective.
