China-based inventors applied for a record-setting number of patents last year.
The country accounted for more than a million submissions, according to an annual report by the World Intellectual Property Organization (Wipo). It said the figure was “extraordinary”.
Many of the filings were for innovations in telecoms, computing, semiconductors and medical tech.
Beijing had urged companies to boost the number of such applications.
But some experts have cast doubt as to whether it signifies that the country is truly more inventive than others, since most of China’s filings were done locally.
