Despite filing an appeal against a ruling that represented the latest victory for Qualcomm in the US chipmaker's global battle over licensing fees, Apple said that, in the meantime, it would take steps to fully comply with the ruling. The modifications would involve adjusting photographs and managing apps via the smartphone's touchscreen - two of the features challenged by the patent.

In the lawsuit, Apple argued that the San Diego-based company had abused its position as the biggest supplier of smartphone chips, while Qualcomm has countered that Apple is using its intellectual property without paying for it. Apple hasn't withdrawn its appeal, and its phones remain on store shelves - for now, at least.

"Based on the iPhone models we offer today in China, we believe we are in compliance," Apple said in a messaged statement. "To address any possible concern about our compliance with the order, early next week we will deliver a software update for iPhone users in China addressing the minor functionality of the two patents at issue in the case."
