Chinese equipment and handset vendor Huawei filed lawsuits in the US and China against South Korea’s Samsung, claiming it infringed on its mobile technology patents.

The Shenzhen-based company, now the third largest smartphone maker in the world, said it filed the lawsuits in the District Court for the Northern District of California and Shenzhen Intermediate People’s Court. It is seeking compensation for Samsung’s alleged infringement of its intellectual property, including patents relating to cellular communications technology and software used in Samsung’s mobile phones.

Huawei said in a statement that “as a major holder of standard essential patents relating to cellular networks, Huawei is committed to licensing these patents on fair, reasonable, and non-discriminatory terms, but it believes that it is entitled to reasonable compensation from firms that use its technology without such a licence”.

Ding Jianxing, president of Huawei’s intellectual property rights department, added: “We have seen a large number of patent cross-licensing agreements signed in the industry to ensure legitimate use of technologies, as this is the basis for the healthy development of the smartphone industry.”

Huawei has signed cross-licensing agreements with many of its competitors. In January Huawei and Ericsson extended a global patent cross-licensing agreement, which includes the payment of royalties to Ericsson from 2016 onward. The deal covers both companies’ standard-essential patents, including for 2G, 3G and 4G technologies.
