US sanctions spur 72% rise in China's open-source innovation, study finds

A study of Chinese patent filings from 2010-2022 shows a 72% surge in citations of open-source scientific literature in patents from US-sanctioned firms, indicating a pivot to reverse-engineering and indigenous R&D. This suggests US export controls are accelerating, not stifling, China's science-driven innovation, challenging the efficacy of the Entity List strategy.
