ZTE launches new salvo against Huawei

BEIJING - Chinese telecommunications equipment maker ZTE Corp has demanded rival Huawei Technologies Co stops making and using equipment related to fourth-generation time division long term evolution (TD-LTE) technology, expanding the legal battle between the two Chinese telecom giants.

In a lawsuit filed at the Shenzhen Intermediate People's Court, ZTE alleged that Huawei infringed on three TD-LTE patents. The company also demanded Huawei stops participating in large-scale TD-LTE trials in seven Chinese cities that started in January.

The move came after Huawei filed four lawsuits against ZTE in Germany, France and Hungary at the end of April, accusing it of patent and trademark infringements.
