Huawei Technologies, the world’s largest telecom equipment maker, initiated a patent lawsuit against Samsung at the intermediate people’s courts in Shenzhen and Quanzhou, as confirmed by the spokesman of Huawei on Jul 6.

Huawei instituted this legal action against five companies including Samsung on accusations of intellectual property (IP) infringement. Specifically, it asks for 80 million yuan in compensation for violations of its high-valued patents on mobile terminal and display-related processing methods applied to a range of Samsung smart phone models including the Galaxy S7, Galaxy S7 edge and the Galaxy J5. Additionally, it also seeks a 500,000 yuan compensation from the defendants to cease infringement.

Apart from Samsung, Huawei also sued US-based mobile carrier T-Mobile in a move to protect its IP rights. Both lawsuits followed the previous ones brought on May 25 at the Intermediate People’s Court in Shenzhen (Huawei vs. Samsung) and in 2014 at the District Court for the Northern District of California in San Francisco (T-Mobile vs. Huawei), respectively.

A senior expert in the smart phone market pointed out that the two parties are likely to come to a mutually beneficial agreement despite their rivalries since Samsung also serves as Huawei’s supplier for components.

On a separate note, Apple and Huawei have signed a series of cross-licensing agreements covering wireless communication technologies, allowing each side to apply for corresponding patents, according to records from the State Intellectual Property Office. However, no such agreements has yet been reached between Huawei and Samsung.

Samsung has not commented on the latest lawsuit as of press time.
