China now files more AI patents than the US, but US patents are more valuable

Researchers developed a new way to count AI patents, improving on existing methods. It turns out China now files more AI patents each year than the US, but US patents are more valuable to companies.

For years, the US has been seen as the leader in AI innovation. This paper shows that China has caught up in raw patent numbers, but the quality and economic impact of US AI patents remain higher. This means that while China is producing more AI inventions, US companies are still getting more financial benefit from theirs.
