I'll ask again then. How can one know from reading a patent whether or not it's a pure troll?

Patents don't troll. People do. For example, people who run companies, like the shell companies IV incorporates.

It's not the patent that reveals trolling. Rather, what indicates trolling are the actions of the person running the company that controls the patent.

Perhaps I am misunderstanding your question.

No, I think we understand each other. I was replying to a comment about reading a patent to see if it was a "pure troll" which is impossible.
