Does that mean the patent for the gear is now invalid?

Ghostery adds some weird play button you have to click to view the article, not sure what that is but it's new and annoying.
It's not. The button is there to temporarily (or not) enable a tracker, when it's necessary for function - apparently, Ghostery decided the text is behind a tracker. It's strange though, I'm using Ghostery too (latest version), nothing enabled, and I didn't get the play button.
Okay if you own a patent and sued someone for it, it's time to hand back the money!

Because evolution isn't planned, it involves selection from randomly[1]-occuring variations each of which has a extremely low probability. Certainly, we see some some traits that arise independently in different populations in different places with similar traits and are preserved and develop in similar ways, but the fact that a feature that contributes to fitness arises uniquely in one place is far from surprising.
[1] well, really, many of the processes are highly-chaotic more than random, but that's beside the point here.

There's never been a dichotomy between organic and mechanical. All things that move are mechanical. 'Mechanical' simply refers to motion. 'Organic' is a similarly blurry categorization. The terms you're looking for are 'natural' and 'artificial,' as in "of nature" and "of artifice (created by man)." These are natural gears, which are so surprising because we'd long assumed the gear itself to be an artificial concept.…

"It may be that his choice of words conflicts with his meaning, or at least conflicts with your interpretation of his meaning, but doesn't make his original word choices less specific in their inherent meaning."
Not sure I understand what you're saying here. My point is that the words he used were used to frame a false dichotomy, and that the use of more precise words for what (I interpret) he was trying to get at would have improved his thought experiment. As I mentioned, I think he raised some good points, regardless of word choice.
As I also mentioned, "mechanical" (literal) and "organic" (literal) do not form a dichotomy; they are not mutually exclusive categories. Surely you would agree here, as you seem to be saying as much.
"Maybe I'm too far down the rabbit hole, but the Industrial Revolution hadn't even occured to me. There is plenty of mechanical action in the human body, and those have certainly been solids long before Latin came around."
Again, see my point about connotation vs. denotation. The IR is roughly when connotations about the word "mechanical" started muddying the waters. (We should note that the ancient Greeks, from whom the word 'mechanics' descends, were certainly prolific engineers in their own right -- but they were careful not to blur the lines the way English has).
At any rate, I brought up this point simply to give the OP some credit, i.e., that I can see how it's easy to use the word "mechanical" to refer to "artificial," given that modern-day connotation is heading in that direction. This was a side point at best, though, and not the focus of my post.
I apologize to you, and to the OP, and to any unfortunate readers of this discussion, for dragging us down what is indeed a rabbit hole.
