China has remained the largest submitter of international patent applications under the Patent Cooperation Treaty with the number reaching 69,610 in 2023, according to the World Intellectual Property Organization in March 2024.

The PCT is one of the most important international treaties in the field of intellectual property. It was concluded in 1970 and now has 158 state parties. This year marks the 30th anniversary of China's participation in the PCT.

In 1994, patent applications via PCT from China were only 98. By 2023, the number increased to nearly 70,000, ranking first in the world for five consecutive years.

More than a quarter of the world's PCT applications have been submitted to the China National Intellectual Property Administration, said Lisa Jorgenson, deputy director general of WIPO.
