Your concept is fundamentally flawed. When climbing, you want your center of mass vertically over the bottom bracket.
The problem is that the grade of the hill causes the bike to rotate raising the front wheel. That's why standing on steep grades works, your center of mass moves forward so that it remains over the bottom bracket.
By going more upright, you're moving your center of mass backwards. You keep your seat, but your center of mass is in the wrong place.

That is correct, but when you climb out of the seat, your hips rise and fall 5 or 6 inches TWICE per crank revolution. You are lifting your upper body 1 foot per crank revolution, while being seated means you don't lift your upper body at all. That is why you might last 30 seconds, or 4 minutes, but it's a huge waste of energy that forces you back into the seat.

And I can stand and pedal for miles, not minutes.

You are still doing the same work and the position confers no mechanical advantage I can see. Plus the additional weight of the stem must eliminate any advantage if there were one. Plus the bulkiness of the device would increase drag and additionally the Fred factor that would only lean towards embarrassment and reduced effort from the humiliation of being caught with such a dorky device.

Or just get proper gearing...
If you have appropriate hearing you don't need to push against anything more than a fraction of your body weight. Froome can climb at 400+W, and weighs about 160lbs. He doesn't need extra weight on the pedals. Of course he also isn't trying to mash 30rpm uphill...

Seems Datlas is right, eat less and ride faster.

The number one thing slowing you down on the flat is air resistance. Fat people are even less aero than the rest of us, because the air has so far to go to get around them. But aerodynamics aren't really an issue at climbing speeds, so fat people just fly up the hills like there's pizza at the top.

This is like the original Schwinn Stingray. I could climb all day out of the saddle on those, because my back was straight up and down, had to zig-zag of course.

On sprints to the finish, its always off the saddle. Even at steep finish lines.
Comparing two riders of different weight only shows that difference. But the bar thing is about the one same rider using different positions.

As for the OP. The raised clip on handlebars are a stupid idea, at least as far as being a performance aid to climbing.

I don't agree with OP's reasoning at all but ... there are times when climbing, standing out of the saddle, when I wish that my handlebars were higher because I'm bending over with the low bars or else having to crouch somewhat.
Moving back on the seat, sitting up more - on climbs I only do that when I'm trying to rest by going really slow. Maybe this invention facilitates that and would be useful for that purpose for some people. But for going up "4% faster" I'm out of the saddle over the pedals, and if I'm going faster still I may be forward of the pedals and pulling up on the bars, which is opposite what OP claims. I'd probably leave that part out of the sales pitch.

This silliness has now popped up in Touring, in case you need more.

I can't see how that would help. It looks like a hinderance to me standing up and leaning forward.
