Nvidia Sues Samsung and Qualcomm

Is anyone up to speed on this ?
I don’t get it, because nvidias blog is lot of legal talk basically, although I didn’t read all of it and the news articles are all for the dumb masses not talking about anything in specific.

What exactly is the nvidia patent that these companies infringe upon and how ?

It has to do with 7 patents around GPU’s:

In general the concepts around:
The entire concept of the GPU, or a dedicated graphics processing chip
Programmable shading
Unified shading
Multithreaded processing on a GPU

patenting the entire chip is a bit much however copying the way to utilize it and the way it functions is fine , seeing as qualcomm may have done this without permission then .
