Charles Duan, director of technology and innovation and a senior fellow at the R Street Institute, testified that the draft legislation would go too far in permitting the patenting of laws of nature. “The draft legislation will inhibit scientific research by locking up with patents the laws of nature that are the foundation of scientific progress. It will balkanize ownership over natural resources such as the human genome, forcing scientists to overcome massive legal complexities before they can even begin basic research,” he said.
