Apple is seeking more than $700 million in additional damages and interest while arch-rival Samsung wants a new trial in the wake of a verdict that saw the US technology giant awarded $1 billion.
In a massive US court victory, a California jury declared on August 24 that the South Korean electronics giant should pay Apple $1.049 billion in damages for illegally copying iPhone and iPad features for its flagship Galaxy S smartphones.
But in a court document filed late on Friday, Apple said it "is requesting an amendment to the existing verdict and a total judgment" of more than $707 million, noting that the amount it received did not adequately cover Samsung's infringements on its patents.
In another document, Samsung underscored that "the court's constraints on trial time, witnesses and exhibits were unprecedented for a patent case of this complexity and magnitude, and prevented Samsung from presenting a full and fair case in response to Apple's many claims."
Samsung "therefore respectfully requests that the Court grant a new trial enabling adequate time and even-handed treatment of the parties," the document said.
Apple and Samsung have been at loggerheads over dozens of patent lawsuits in 10 nations, accusing each other of copying technologies and designs.
While the US verdict was seen as victory for Apple, a Japanese court rejected its claim that Samsung stole its technology and also awarded legal costs to the South Korean firm.
