Huawei Files Complaint Against T-Mobile Amid Widening Patent Campaign

Huawei has extended the scope of their patent-backed battle, now targeting U.S. telecommunications company T-Mobile. It comes as the Chinese smartphone vendor recently filed a second filing against Korean electronics maker Samsung over a patent dispute.

Huawei filed a complaint against T-Mobile on Tuesday to the U.S. District Court for the Eastern District of Texas, claiming the later company had infringed on a wireless network patent held by the Chinese company.

A handful of Chinese smartphone makers, including Huawei, Lenovo and ZTE have been rapidly acquiring and developing pools of patents in an attempt to challenge leading global companies as the Chinese vendors seek to expand.

In May, Huawei began legal action against Samsung int he U.S., claiming the Korean company had violated 11 patents pertaining to mobile technology. Yesterday it was revealed that Huawei filed a second patent suit against Samsung to a court in Shenzhen, where the Chinese company is based.

Huawei has been aggressively building out their high-end mobile business, looking to take a bigger bite out of the U.S. and European markets as local Chinese demand stagnates. The company has amassed over 50,000 patents as of the start of 2016.
