US sanctions were meant to slow China’s tech industry. Instead, a 72% rise in science-linked patents reveals how restricted firms are building their own path to innovation

Chinese firms sanctioned by the US are increasing patent citations of academic research. This shift suggests a move towards domestic expertise and self-reliance in innovation. Sanctioned companies show a 72 percent rise in science-linked patents after restrictions were imposed. While Chinese research output is growing, US firms still lead in scientific depth. Prolonged decoupling could lead to separate technology ecosystems, researchers warn.
