Qualcomm Inc said on Thursday it has applied for a compulsory enforcement of a preliminary ban on sales of some iPhone models in China.
The United States tech giant said its application was sent to Enforcement Tribunals, part of the Chinese court system.
The move came after the Fuzhou Intermediate People's Court issued a preliminary injunction to ban sales of iPhone 6S through iPhone X models in China. The court found Apple Inc violated two of Qualcomm's patents.
