I would like to have a breakdown of individual vs. organization-backed inventors. Quite a lot of - but I don't know how much, relatively - patent applications are filled by individuals with help and in the name of their employer; there are companies who are proud of the number of patent applications they file per year - and those are mostly bona-fide inventions, not patent trolling.

(It's entirely expected, if you think about it - a big company employing skilled specialists doing actual[0] engineering is bound to become a patent mill, as those workers have to invent their way out of new problems.)

I suspect that this might be the primary way patents are applied for and awarded, and it's different from the usual narration, that patents are either small inventors wanting to ensure the market rewards them for their hard work, or evil megacorps buying them up as a part of peace-through-MAD balance with other evil megacorps.
