THE Shenzhen-based telecom giant, Huawei, has filed a lawsuit at Quanzhou Intermediate People’s Court in Fujian Pro-vince against its South Korean rival, Samsung, for patent infringement and demanded 80 million yuan (US$12 million) in compensation from Samsung, the Shenzhen Evening News reported Thursday.

    According to previous media reports, Huawei sued Samsung in two other courts — one in California, the United States, and the other in Shenzhen — on May 25, saying that several of its communication and software inventions had been used in Samsung’s phones without its authorization.

    “The lawsuit in Quanzhou was filed at nearly the same time as the previous two lawsuits, but the Quanzhou Intermediate People’s Court didn’t disclose the case information until recently,” said a Huawei staffer. The Quanzhou Intermediate People’s Court has accepted the case, according to the report.

    The lawsuit in Quanzhou focuses on one of the patents that Huawei believes was infringed by Samsung. Samsung’s five branch companies in China were all sued by Huawei, which demanded 80 million yuan from Samsung in compensation for the patent infringement and another 500,000 yuan to cover Huawei’s expense on curbing the infringement.

    According to Huawei, its technical inventions have been used in Samsung products, including its smartphone Galaxy S7, after Huawei obtained an involved patent from the State Intellectual Property Office in June 2011. Samsung didn’t respond to the case at press time.

    Huawei also filed a complaint against American wireless networking operator T-Mobile in a court in Texas, the United States, on Wednesday. Huawei said T-Mobile has been using its patents while refusing to enter a nondisclosure agreement with Huawei in 2014. (Zhang Yang)
