Nikon Z9 sensor is not only produced but also patented by Sony?

Sony A1 vs Nikon Z9 specs comparison that can be seen here.

A trusted source told me that of course The new Nikon Z9 sensor has been produced by Sony. But he also said it’s patented by Sony and is Nikon licensed to use it.

I know this is going to create some shitstorm, but this is what a reliable source told me (the same that hared all correct A7IV specs). So there is a chance he is right on this too.

Anyway, I am pretty sure that regardless of this rumor Sony knew well in advance about this Nikon camera. This leads me to believe Sony knows well what they have to do next with the A1II.
