It's the latest filing in a suit set to go to trial June 3. CNEX claims that Huawei spent years trying to steal its data storage secrets, while Huawei has countered with its own suit, filed earlier this month, alleging CNEX is the one that's been engaged in theft of trade secrets. Both companies have denied wrongdoing.
A Huawei spokesman called reports of CNEX's newest claims "misleading" and the allegations "unsubstantiated."
On Thursday, a Huawei spokesman said the company's recent filing against CNEX stems from a 2017 action
The case comes as Huawei finds itself at the center of controversy in the U.S. The company, which makes computer networking equipment, is now subject to a "blacklisting" ban by the Trump administration, and faces criminal actions, including a federal trade secrets case in the state of Washington and allegations of fraud against its CFO, who is currently awaiting an extradition hearing in Vancouver.
CNEX has alleged that a Huawei deputy chairman, Eric Xu, directed an employee to pose as a potential customer and submit a report on his findings in order to obtain trade secrets for the company's chip research and development department.
CNEX also claims Huawei had ties with China's Xiamen University, and misappropriated trade secrets through that relationship.
Huawei's concurrent action against CNEX stems from a 2017 trade secrets theft case involving one of CNEX's founders, Yiren Huang, who now serves as the company's CTO. Huawei says Huang, a former employee, stole trade secrets and used them to form CNEX. "Huawei looks forward to pressing our claims against CNEX and Mr. Huang at trial," a Huawei spokesman said via email.
