The Munich-based office noted that patent applications for digital technologies soared in 2019, driven by the rise of 5G internet and artificial intelligence (AI).
Huawei topped the ranking ahead of South Korean heavyweights Samsung and LG.
EPO President, Antonio Campinos, said in a statement that “the rapid rise of digital technologies is the most striking trend from our 2019 index.
“It is important that companies and researchers in Europe seeking to protect their inventions find a level playing field with their competitors from Asia and the U.S.
“It is also important for companies to be able to maintain a strong position in the global technology market,’’ Campinos said.
The index showed digital communication patents up 19.6 per cent, overtaking medical technology to claim the top spot for the field with the most innovation.
Europe, China and the U.S. each accounted for around a quarter of all patent applications filed with the EPO in this field.
The EPO said 2019 was a record year in terms of patents applications filed, which totalled around 181,000.
