Going around patents is not the root cause; they would still save money if they had their own silicon and paid royalty.I've got news for you... Apple is indeed making their own displays and batteries. The displays have been in development for many years and are microLED iirc (not mini); rumoured to possibly debut in the Apple Watch X this/next year. For the battery, it's unclear how long Apple's been working on that.
I think the only way around the modem patents is if Apple uses a fundamentally different tech, like optical computing hardware. QC seems to think their patent coverage is air-tight.
