I once suggested this for copyright terms, but someone pointed out a big problem: what is the unit that that "$1" fee covers? I can write an entire book under 1 copyright, easily keeping it going for a decade with your regime. But a photographer produces hundreds or thousands of copyrighted works a year. You might try doing your regime with the number of claims, and the company can decide how many to keep fresh, but it then leads to weird edge-cases like keeping a few things secret for now to patent later -- which is the opposite of what the patent system intends. Patents encourage people to publish their inventions for others to study, in exchange for limited exclusivity to market and/or use their invention.

Yeah, I don't think it works for copyrights, but patents already seem to have this solved. There's already a set unit for them, and they already cost a substantial amount of money (unlike copyright, which is currently free). Keeping things secret now to patent them later is a problem, but no worse than it is now, I think. The same incentives apply to the exponential scheme as to the current hard limit. You'd keep the requirement to file within a certain time of the first public reveal, so you'd have to move quickly if you wanted to patent anything you were actually going to use.
