Apple had been seeking $US27 billion ($38 billion) in damages from Qualcomm,amid claims that it charged"disproportionately high"fees to access its patents for high-speed smartphone modems,which control how the phones access the internet. The chip supplier's business model involves charging manufacturers up to 5 per cent of the selling price of a device to license its patents. Apple argued its royalty demands were extortionate and directed its suppliers to cease paying royalties to the company.

Qualcomm was also seeking damages of up to $US15 billion in lost revenue. It claimed that it didn't force Apple to use its chips and that the company was simply trying to force a better deal.
