Huawei Technologies Co. Ltd.'s outspoken chief legal officer Song Liuping has stepped back into the spotlight as the Chinese tech giant pursues patent infringement litigation against rival Verizon Communications Inc. 

"Verizon's products and services have benefited from patented technology that Huawei developed over many years of research and development," Song said Thursday in a statement announcing that Huawei had filed two federal lawsuits a day earlier against Verizon in the U.S. District Court for the Eastern and Western districts of Texas.

The complaints allege that Verizon infringed on Huawei's patents required for implementing the G.709 standard for optical network technology, which "has become a key component in meeting the modern demand for high speed, reliable communication over various type of networks."

Huawei adds in the suit, "Verizon uses this technology to transmit massive amounts of data in a stable and safe way from numerous base stations or access points to remote destinations. Thus, the technology is important to the core of Verizon's business—enabling individuals and businesses to place calls, access the Internet, and transport data safely, reliably, and quickly." 

Verizon dismissed Huawei's lawsuits as "nothing more than a PR stunt." 

"This lawsuit is a sneak attack on our company and the entire tech ecosystem. Huawei's real target is not Verizon; it is any country or company that defies it. The action lacks merit, and we look forward to vigorously defending ourselves," Verizon added in a statement. 

Meanwhile, Huawei asserted that it negotiated with Verizon in an attempt to reach a licensing agreement and only filed suit after the talks failed. 

"For years now we have successfully negotiated patent license agreements with many companies. Unfortunately, when no agreement can be reached, we have no choice but to seek a legal remedy," Song said. 

He added, "This is the common practice in the industry. Huawei is simply asking that Verizon respect Huawei's investment in research and development by either paying for the use of our patents, or refraining from using them in its products and services."

This isn't the first time that Song has served as the voice for Huawei. Last May, he held a press conference to denounce the U.S. government's ban on Huawei equipment as "not normal" and "trial by legislature."

Several months later, Microsoft Corp. president and chief legal officer Brad Smith joined Song in speaking out against the Trump administration's handling of Huawei. 

"To tell a tech company that it can sell products, but not buy an operating system or chips, is like telling a hotel company that it can open its doors, but not put beds in its hotel rooms or food in its restaurant," Smith said. "Either way, you put the survival of that company at risk."
