China Leads All Nations in Publication of Chemical Patents

China trailed Japan’s patent office, the World Intellectual Property Organization (WIPO), and the United States’ patent office (USPTO) for more than a decade, but passed the USPTO in 2005, WIPO in 2006, and exceeded Japan for the first time on a monthly basis in 2008.
