China is working to further increase the efficiency of its patent application review process, aiming to reduce examination times this year to 15.5 months.

The target was revealed by the China National Intellectual Property Administration (CNIPA), the country’s top regulatory body, in its recently published annual working guidelines. The processing time in 2023 was 16 months, making it one of the most efficient in the world.

The newly revised rules for implementing the Patent Law, which came into force in January, encompassed several new measures aimed at improving the quality of analysis. To support the development of these emerging sectors, the regulatory body also highlighted the task of perfecting patent examination standards in areas such as big data, artificial intelligence and genetic technologies this year, and planned to strengthen its efforts to expand the scope of review.

In 2023, a total of 921,000 invention patents were authorized in China. The exam’s accuracy rate reached 94.2%, according to Shen Changyu, head of CNIPA. China will continue to improve patent examination standards in new fields and new forms of industry to facilitate the granting of patents for green and low-carbon technologies and future industries, Shen said late last year.
