Nokia’s patent dispute persists in China despite deal with one smartphone maker

Finnish telecom equipment maker Nokia said on Thursday it had signed a 5G patent agreement with one of China's leading smartphone makers Honor, but its legal battles with other Chinese companies over patents continue. Nokia, once the world's number one mobile phone maker, holds a significant patent portfolio of some key technologies needed in phone manufacturing and the resulting licensing revenue represented 39% of operating profit in 2022. Nokia has been in legal disputes with Chinese device makers Oppo and Vivo in various countries over the use of 4G and 5G patents since 2021 which have not been resolved, a source familiar with the matter said.
