The Shenzhen Intermediate People's Court said Samsung should cease acts that infringe upon two 4G standard essential patents over telecommunication technology and equipment held by Huawei.
The court said Huawei owned the two 4G patents and Samsung violated Huawei's patent rights.
The court also found that Samsung "maliciously" delayed negotiations and was at fault.
It said the case was one of the most complicated IPR cases in the world. The court trial lasted 18 days.
