The provisional serves as a timestamp only. It's literally not reviewed. The only reason at all to file a provisional is if you're going to file the proper one. Goods that are actually patented are under the 'proper' ones, and do not get the classic "protection" that we think of. The only thing the provisional really does is serve as the 'timestamped-steak-in-the-ground' that only you can claim as your timestamp. But it comes with conditions. You can't start selling your goods as-though-patented until you file the patents. You can put 'patent pending' on them after you file the big one and it's under review. But the provisional one doesn't really get you the 'patent pending' part at all. That's my not-even-close-to-a-lawyer version that I've learned in the last few months.

But what complicates this even more is that I don't really want to sit on the tech at all. I want it to become ubiquitous and (eventually) a standard (like how Yubico/Yubikey led to FIDO/FIDO2 later).

But others in the thread also bring up a totally valid point: I need to prove this has teeth with real people somehow.

I think I may have to bight the bullet and fork over some savings to get the proper patent done. I need to get busy with R&D to finalize the design.
