In the case of Jarecki, Former Collector of Internal Revenue, et al. v. G.D. Searle & Co., 1960, the U.S Supreme Court was tasked with interpreting a provision in the tax code that provided special treatment for income derived from "discovery or exploration" within certain industries such as oil and gas but did not explicitly include pharmaceuticals. The respondent company, G.D Searle & Co., argued that their discovery of new drugs should qualify for this preferential tax treatment because it involved similar processes to those used in oil and gas exploration - namely research and development leading to commercial exploitation. The court disagreed with this interpretation on two grounds: firstly, they found no evidence that Congress intended to extend these benefits beyond mineral resources; secondly, they noted significant differences between drug discovery (which involves creating something new) and resource extraction (which involves finding pre-existing materials). Therefore, despite similarities in process at a high level of abstraction – both involve some form of 'exploration' – these activities were fundamentally different when viewed more closely. Consequently, the court ruled against G.D Searle & Co., establishing an important precedent about how narrowly courts should interpret specific provisions within broad legislative frameworks.

In the dissenting opinion for Jarecki v. G.D. Searle & Co., Justice Whittaker disagreed with the majority's interpretation of "discovery" in Section 4562 of the Internal Revenue Code, which provides a tax deduction for expenses incurred during research and experimentation leading to new products or processes. He argued that this provision should apply not only to completely novel inventions but also to significant improvements on existing ones, as long as they are non-obvious and contribute substantially to their utility or efficiency. In his view, such advancements constitute discoveries within the meaning of the statute because they involve finding something previously unknown or unrecognized - an essential element of discovery according to its dictionary definition. Therefore, he would have held that Searle was entitled to claim deductions for its development costs related to two drugs derived from known substances since these developments represented substantial improvements over what was previously available.
