Huawei sues Samsung over patents
The Chinese firm said it was pursuing its South Korean rival in two courts - one in California, the other in Shenzhen.
According to Huawei, several of its cellular communications and software inventions had been used in Samsung's phones without its permission.
The specific patents involved have not been disclosed.
However, Huawei has said at least some of them are classed as Frand - an acronym referring to "fair, reasonable and non-discriminatory".
This means the Chinese company has committed itself to offering anyone a licence so long as they agree to a non-excessive compensation.
This kind of agreement is common in the tech sector as it makes it possible for different companies' products to communicate and share data formats with each other.
Huawei's intellectual property chief indicated it was seeking permission to use some of Samsung's technologies in return rather than seeking a payment.
"Thus far, we have signed cross-licensing agreements with dozens of our competitors," said Ding Jianxing.
"We hope Samsung will respect Huawei's R&D investment and patents, stop infringing our patents and get the necessary licence from Huawei, and work together with Huawei to jointly drive the industry forward."
A Samsung spokesperson responded in an email to the BBC saying "we will thoroughly review the complaint and take appropriate action to defend Samsung's business interests".
