Apple has demanded Samsung Electronics pay it 405 million dollars for copying vital iPhone and iPad features.
The move comes as a billion-dollar patent fight between the world's two biggest smartphone makers resumed in a Silicon Valley courtroom.
According to news.com.au, an Apple lawyer made the demand during opening statements in a trial to determine damages.
The statements included a video of Apple founder Steve Jobs unveiling the first iPhone at the now-famous January 9, 2007, Macworld conference in San Francisco, the report said.
Since then, Apple has alleged that Samsung has embarked on a copying campaign to keep pace in the exploding smartphone market, the report added.
