China, which last year overtook the United States as the world’s top filer of international patents, a key measure of technical innovation, increased its lead significantly in 2020, the UN said Tuesday.

Even as Covid-19 took a vast human and economic toll, international patent applications continued to grow strongly, with China leading strong gains from Asia.

A record 275,900 international patents were filed in 2020, marking a four- per cent hike over 2019, the UN’s World Intellectual Property Organisation said in its annual report.

“Innovation remains resilient,” WIPO chief Daren Tang told reporters.

He stressed though that the filings in 2020 mainly reflected innovations and inventions made prior to the pandemic, since it takes about a year for applications to make their ways through the system.

But the growth in patent filings should still be seen as a positive signal, according to WIPO.

“The fact that there wasn’t a sharp cut-back in international patenting suggests that companies continued to invest in the commercialisation of their technologies during the pandemic,” WIPO chief economist Carsten Fink told reporters.

By comparison, he said, international patent filings plunged nearly five per cent during the global financial crisis in 2009.

WIPO’s complex system of registering international patents involves multiple categories.

In the main category -- the Patent Cooperation Treaty, or PCT -- China remained at the top of the ranking with 68,720 filings.

That marks a jump of more than 16 per cent from 2019, when China passed the United States.

At that point, it was ahead by just over 1,000 applications but it has now expanded its lead to nearly 10,000.

In 2000, China made just 782 international patent filings.

“The growth rate in international patent applications from China has been very high,” Fink said.

The United States meanwhile also increased its international filings, by three per cent, to 59,230.

China and the United States were followed by Japan, South Korea and Germany as the world’s top patent filers, WIPO said.

The United Nations agency highlighted significant growth in applications by several smaller filers as well.

Saudi Arabia, for instance, saw its international patent applications balloon last year by over 73 per cent to 956, while Malaysia, Chile, Singapore and Brazil also made big advances.

WIPO’s report showed Asian-based applicants accounted for 53.7 per cent of all filings, up from 35.7 per cent a decade ago.

For the fourth consecutive year, China-based telecoms giant Huawei Technologies topped the global ranking in 2020, with 5,464 PCT applications.

It was followed by Samsung Electronics of South Korea, with 3,093; Misubishi Electric Corp. of Japan, with 2,810; South Korean LG Electronics at 2,759 and Qualcomm of the United States at 2,173.

Computer technology accounted for the largest share of published PCT applications, with 9.2 per cent of the total, followed by digital communications and medical technology.

This is not necessarily linked to the Covid-19 influenced realities of 2020, Fink said, adding that the 2021 filings should provide more insight into pandemic-fuelled technology trends.

“These patents relate to pre-pandemic innovations so this is not a story about how the crisis has affected the direction of innovation,” he said.
