The World Intellectual Property Organization, which oversees a system for countries to share recognition of patents, said 58,990 applications were filed from China last year, beating out the United States which filed 57,840.
China’s figure was a 200-fold increase in just 20 years, it said. The United States had filed the most applications in the world every year since the Patent Cooperation Treaty system was set up in 1978.
More than half of patent applications – 52.4 % – now come from Asia, with Japan ranking third, followed by Germany and South Korea.
Ownership of patents is widely seen as an important sign of a country’s economic strength and industrial know-how.
WIPO’s head, Francis Gurry, told a news conference China’s success was “down to a very deliberate strategy on the part of Chinese leadership to advance innovation and to make the country a country whose economy operates at a higher level of value.
“It is working, and intellectual property is certainly part of that strategy. I would put it down to that broad movement towards becoming a higher-value economy,” he said.
According to the WIPO data, China’s Huawei Technologies [HWT.UL], the world’s biggest maker of telecoms equipment, was the top corporate patent filer for the third consecutive year.
The United States has called on countries to ban Huawei equipment from new mobile phone networks, arguing that its technology could be used by China for spying. Huawei denies that its technology poses a security risk.
Asked to what extent China’s lead was due to state subsidies, Gurry said: “It’s a model which does use state subsidies to a greater extent perhaps than Western economies might typically use state subsidies. So yes it certainly plays role.
“But I think it is very interesting to compare the United States of America as one example of the high performing economy, that has been top of innovation for a long time, a completely different model than what is happening in China.
“The jury is still out…perhaps both are successful.”
