From 1993 to 2021, without fail, this company received more patents in the US than ANY other company. Why has it stagnated for decades?

Can you guess what company this is? I'll put in the comments.

Hint: The 5 year CAGR is -8.22% and the 10 year CAGR is -30.58%. Here is a plot of revenue each year of some major companies. I blocked out 3 other companies, as the one I'm talking about is one of them. Here is its stock price performance over history.

How are we measuring innovation in the modern economy? Are patents relevant? Why has this company failed so hard?
