What is the invention? I recall reading, some 15 to 20 years ago, about the difficulty of self-verifying systems. This security chip verifies the bios is not altered, but what verifies the security chip?

I don't know if it's possible, but I think a more ground-breaking product would be to provide a way for customers to validate assertions about the entire process (design, manufacture, distribution and installation). Otherwise the customer is still left blindly trusting corporations and their undisclosed interests.
