My experience of being in technology companies for > 30 years is that every time something hits "it's everywhere" status people crawl out of the wood works claiming they have both prior art and a patent on it. The entire submarine patent game was about having dozens of unclear patents in the "application" phase, only to sharpen them up and file them as things like RISC-V debut. They become successful and suddenly poof the current patent assignee (typically a law firm) starts chasing around suing people and making people's lives miserable until their patent is invalidated.
