On June 4, 2025, Nanjing’s Intellectual Property Protection Center (NIPPC) announced it is banning the use of artificial intelligence (AI) in drafting patent application documents submitted for pre-examination. China’s pre-examination system enables applicants to submit their patent applications to a regional office for an initial examination and potentially receive expedited examination at China’s National Intellectual Property Administration (CNIPA) if certain conditions are met. The NIPPC stated that it was determined that “relevant content [of patent applications] was directly generated by artificial intelligence.
