Apple has been told it must pay $234 million (£151 million) to the University of Wisconsin’s research company, after a court found that it had breached patents used in its A7, A8 and A8X chipsets.
The Wisconsin Alumni Research Foundation (WARF) said it developed chip efficiency technology which Apple then went on to use without permission in the chipsets, found in the iPhone 5s, iPhone 6 and iPad models from 2014.
It has been suggested that Apple could have to more than $800 million to WARF, but in a further hearing the judge in the case Apple had not wilfully breached the patent.
Apple said that it will appeal the ruling, but offered no further comment. In court, it has argued that WARF deserved no more than $110 million, the amount it received from Intel in an out–of–court settlement in 2008 relating to breach of the same patents.
The case looks set to rumble on into 2016, with WARF filing a lawsuit in September following the launch of the iPhone 6S and iPad Pro. It says that A9 and A9X chipsets used in those devices also infringe on its intellectual property.
