Federal prosecutors are investigating the alleged theft of trade secrets from US businesses and partners, including smartphone-related technology, from T-Mobile’s US arm, sources told the Wall Street Journal.
The latest lawsuit builds on a previous case in 2014 when T-Mobile was awarded $4.8 million after a court ruled Huawei guilty of covertly taking robotic technology, including the smuggling of a robot appendage in a private bag from the T-Mobile testing lab, during a partnership stint between the two companies.
T-Mobile claims that the information gained went on to grant Huawei a competitive edge worth hundreds of millions of dollars.
“With the jury finding misappropriation of trade secrets and breach of contract, we won the first trial that we believe revealed their wrongdoing and began to unravel the Huawei story,” said T-Mobile’s lawyer John Hueston.
The sources said that the current case has reached an advanced stage and is likely to lead to an indictment soon.
US lawmakers are also preparing a proposal to ban chip sales to Huawei and fellow Chinese telecoms firm ZTE.
