Apple Ordered to Pay $5.7 Billion for Infringing Haptics Patent in iPhone, Apple Watch

Its always nice to find good news in my feed

How is this good news? Haptic feedback has existed since the 1970s. This patent should be invalid.

The patent is not on haptic feedback. The patent is on a very specific means of implementing haptic feedback using ferrofluids and electromagnetic actuators that it is claimed (and Apple deemed it good enough to copy, so presumably truly) allows for both a smaller implementation than typical mechanical haptic feedback (i.e. the off-balance-flywheel approach of phones of old), while also allowing for low- or zero- noise compared to “speaker or piezo” based haptic feedback.

There are a lot of shit patents in the world, but on a surface reading at least this seems sufficiently novel that I don’t see why it should be invalid. One also presumes that if Apple had any grounds to invalidate it on prior-art they would have done so.
