The 1980 U.S. Supreme Court decision in Diamond v. Chakrabarty was a landmark ruling that fundamentally transformed the biotechnology industry by establishing that a "live human-made microorganism is patentable subject matter."1

Prior to this decision, researchers and investors faced significant uncertainty regarding whether they could secure patents on organisms, as existing legal standards generally prohibited patenting new organisms discovered in nature. By confirming that genetically engineered microorganisms could be patented, the Court provided the legal certainty necessary for commercial investment in biotechnology.1

This ruling is widely credited with triggering the first major investment boom in the nascent biotech industry, encouraging the formation of new firms and accelerating the development of genetically engineered products. Following this precedent, the scope of patentable innovations expanded over the subsequent decades to include a wide array of genetically engineered bacteria, plants, and other organisms, shaping the modern landscape of genetic engineering.12
