Too late, Its already out in the world. My experience with patents is that they usually make you poorer, much poorer. My gramps has 67 in tech and my dad has about 30 in medicine and chemistry.
The easiest thing in the world is to shell out capital and secure your IT. The REALLY hard part is to bring it to market and keep the vultures from robbing you. It consumes your entire life.
Better to be first in and secure brand recognition and SOPWAMTOS the hell out of it.
Jefferson was right. IT should be free and open.
Re- all the haters here. I find your behavior bazaar. All of your bikes that you ride past, present and future consist of tech that was ridiculed in the same fashion. This is a concept and a working prototype designed to solve a specific issue.
There is absolutely a way and a duty to criticize what you see that moves the game forward...and most get it.
I find this very sad as all you have done is pushed yet another highly experienced and accomplished builder away from this site.

Ill give it a go. Id be interested to see if our answers match up...keeping in mind that I do not know all of the assumptions etc.
1. People generally think that smaller frame = stronger/stiffer. Also a square design plus conventional stem puts most people outside their level of flexibility/ROM so they buy off the shelf solutions which generally means smaller frame.
2. To get a tight wheelbase and quick handling to avoid crashes and obstacles and elbows...and preserve the low aero position.
3. Tradition. But also depends on your definition of gravel. For some it means a flat dirt road (think Missouri), for others it means Fast descents down Mt. Umunum. Some people LOVE climbing and just want more air under them to piece together the descent, for others it is the opposite.
4. See #3 but I think that in some cases they should.
5. Some riders are caught in the "no mans land" of tire size and opt in to the higher volume solution but I know that is not what you meant. The only good answer I have off hand is BB/crown height and how that related to handlebar height, center of gravity and ride characteristics.
Again, I dont know all the assumptions. Id like to know how you or others answer these questions. FYI I am a 700c with rare exception kinda guy.

Paging @pvd, would love to hear your thoughts on this!

Badly broken/displaced clavicle, concussion that seems at least to be moderate or worse. I don't like his egocentric manner of the various forums he visits(however I do like some of his design ideas)but I truly wish him a speedy and complete recovery. Get well Peter.

I am probably one of the few people on this forum that can and does do the maths* and I think your comment is rather unfair.
The part that broke looks to be a commercially produced filament wound tube, he would be relying on the manufacturer's data to determine strength etc. Unfortunately brittle fracture in carbon composite structures is not that straightforward, it follows a probability function (described by the Weibull Modulus) which means that even well designed structures will have a finite (but hopefully small) probability of brittle failure.
Accordingly, there is not enough evidence here to state the PVD didn't "do the math", it could well be that he did, accepted a small chance of failure and promply discovered that the bell curve has tails.
*English speaking countries use "maths" as the abbreviation for mathematics, the USA being the exception.

maybe a bit presumptuous to call the bar a proven design given that, technically speaking, a fairly large percentage of the ones in existence have failed in use. i assume his argument is that it's the carbon tubing supplier's fault. may well prove true. i'll be interested to see if he goes back and reviews the tubing used in his other bars of the same design after he heals up
it's in poor taste to kick the man while he's down. i doubt that many other framebuilders would experience similar criticism after a mechanical failure of one of their own bikes. misconduct on forums is not grounds for the withholding of sympathy after a crash
