LIMA/SHANGHAI—China’s Huawei has applied to trademark its “Hongmeng” operating system (OS) in at least nine countries and Europe, data from a U.N. body shows, in a sign it may be deploying a back-up plan in key markets as U.S. sanctions threaten its business model.
The move comes after the Trump administration put Huawei on a blacklist in May that barred it from doing business with U.S. tech companies such as Alphabet Inc., whose Android OS is used in Huawei’s phones.
