Are you daft? If Intel did not file a patent for the improvement, or publish in a jurisdiction that allows first to publish, then it can still violate an improving patent, even if you own the patent to the underlying idea, which I believe the one Intel relied on was dated to between 1999 and 2001.
Now, can you give me the proof that they in no way used the changes to the patent filed there? Can you show, to more probable than not, that the patents are identical and that there is nothing new or novel in the patent filed 11 years later, give or take, when I showed there is a finFET patent Samsung filed which was the 2003 filing:
https://patents.google.com/patent/US6885055B2/en (note, that is not Intel's patent for finFET, because there are multiple types of finFETs and implementations).
So, please, show me the body of evidence proving these patents are identical without any novelty. Please show me that Intel's implementation when building any chip since their first 22nm finFET design did not, in any way, implement what is being discussed in the Chinese patent, if you cannot invalidate it. Then we can sit down and hold your position. But not a second before that.
