In a serious blow to Apple in its legal battle with Qualcomm, a jury in San Diego has found Apple guilty of infringing on three Qualcomm-owned patents in the iPhone.

The jury awarded Qualcomm $31 million in the case, which is the full amount that the company was seeking from Apple after Apple won a ruling that limited the potential payout.

The lawsuit was first filed against Apple in 2017 and there are three patents involved.

The first relates to battery efficiency when it comes to processing graphics.

The third and final patent has to do with managing data traffic in a way that allows apps to download data quicker.

Qualcomm claims that the patents relate to the iPhone 7, 7 Plus, 8, 8 Plus, and X all infringe on the patents — though it seems as though Apple has stopped using it in its most recent smartphones.
