News: Samsung could be embroiled in a new court battle as Huawei seeks a cross-licensing agreement.
The lawsuits cover four patents for mobile devices and eight for networks, according to the Associate Press, which said that Huawei was not asking the court to restrict sales of Samsung handsets.
Both companies make Android smartphones, an area in which Samsung has a robust lead: according to recent Strategy Analytics research, Samsung has a market share in smartphones of 23.6 percent, while Huawei's is at 8.5 percent.
Oracle provoked significant anger from Google when it revealed in court confidential figures about Android's financial performance.
Samsung itself is still embroiled in a patent dispute with Apple, which has spanned several years and many jurisdictions.
Apple has previously won $548 million in a partial settlement of the case.
