Apple Inc and Samsung Electronics squared off again in court on Thursday, as the iPhone maker tried to convince a US district judge to ban sales of a number of the South Korean company's devices and defended its $1.05 billion jury award.

Apple scored a sweeping legal victory in August at the conclusion of its landmark case against its arch-foe, when a US jury found Samsung had copied critical features of the iPhone and iPad and awarded it damages.

Both sides re-convened on Thursday. US District Judge Lucy Koh listened to a range of arguments on topics from setting aside the jury's findings on liability to alleged juror misconduct and the requested injunction.

The hearing concluded with Koh promising to rule at a later date.
