Huawei is accused of 10 separate charges, including conspiracy to steal trade secrets, attempted theft of trade secrets, wire fraud and obstruction of justice. According to prosecutors, Huawei stole trade secrets from T-Mobile. The charges primarily stem from a 2013 incident in which Huawei engineers allegedly took photos and measurements of one of T-Mobile's phone testing robots called Tappy. Huawei used that information to improve its own robot. In 2017, a Seattle jury ruled in favor of T-Mobile in a related suit against Huawei and awarded the telecommunications company $4.8 million.

In addition to the pending trade secrets case, Huawei is also accused of 13 charges connected to sanction violations. The company's Chief Financial Officer Meng Wanzhou is wanted in the US for fraud charges and is currently being held in Canada. An extradition hearing for her case is scheduled for Friday.
