iPhone maker Apple looks to increase the amount of damages from rival Samsung, requesting a retrial in the latest patent case between the companies.
Earlier, a Californian jury awarded Apple $119m (£71m) in damages from Samsung, lower than its demand of $2.2bn. In the lawsuit, Apple accused Samsung of infringing on two of its patents.
Apple noted in its latest court filing that a retrial was warranted based on prejudicial claims by Samsung to the jury.
Apple also filed a permanent injunction to ban Samsung devices that allegedly infringe on its patents. The injunction is sought in the US District Court for the Northern District of California.
The patents cover features such as "slide-to-unlock" on phone home screens, auto-correct for prompts on the spelling of words, and the so-called "quick links" feature for scanning text to identify certain types of structures such as phone numbers, dates and email addresses.
Samsung, in its counter claim, argued that Apple infringed on two of its patents on its iPhones and iPads. Apple has stolen a wireless technology system for speeding up sending and receiving data, Samsung alleged.
After the verdict, Apple claimed that the jury made a technical mistake in awarding damages, forcing it to reconsider the issue. However, a US jury kept the total payment unchanged after additional deliberations.
Samsung is presently the smartphone market leader, accounting for one in three of all devices sold last year. Meanwhile, Apple is steadily losing its market share to low-cost rivals including Lenovo, HTC and Huawei.
Apple sued a number of rival smartphone makers over patent issues, but the legal battle between Samsung and Apple has been fiercer and widely noticed. Apple is looking to ban Samsung from selling its devices in the key US market.
About two years ago, a federal jury found Samsung was infringing on Apple's patents and asked the South Korean electronics major to pay about $930m to Apple. Then also, Apple requested a sales ban on Samsung's alleged infringing devices, but Judge Lucy Koh denied that request.
