Large entities get their patents approved at an 80% rate. Micro entities, the category that includes most independent inventors, get approved at 40%. That is a two-to-one gap in patent allowance rates, and the data from Patently-O’s January 2026 analysis shows it is not shrinking.
Small entities land at 61%, which means the drop from small to micro is sharper than the drop from large to small. For independent inventors trying to protect their ideas through the patent system, these numbers demand specific attention and specific responses.
What the numbers actually say
Patently-O analyzed USPTO disposal data and found the overall allowance rate sits at 74%. But that headline number masks the entity-size breakdown that matters most to independent inventors.
Large entities, typically corporations with dedicated patent departments and outside counsel on retainer, achieve 80%. Small entities, usually startups and small businesses, come in at 61%. Micro entities, the filing status designed specifically for independent inventors and very small companies, get 40%.
I want to be clear about what this means. If you file as a micro entity, you face worse odds than a coin flip. A large company filing a patent on an invention of comparable quality is twice as likely to walk away with a granted patent.
What this means for independent inventors
The gap is not primarily about the quality of the underlying inventions. It reflects differences in prosecution strategy, claim drafting, and the ability to respond effectively to office actions.
Large entities file continuation applications at higher rates. They have patent attorneys who know individual examiners’ tendencies. They draft claims with fallback positions built in from the start. When they get a rejection, they have the budget and expertise to craft a targeted response rather than abandoning the application.
Most micro entity applicants are doing none of those things. Many file provisional applications that lack sufficient detail, draft claims too narrowly, or simply abandon after the first office action because they don’t understand the rejection or can’t afford to respond. If you are filing as a micro entity for the first time, knowing these patterns is the first step toward beating them.
What inventors should do now
- Treat your provisional as a real filing. Write it as if the examiner will read every word, because eventually they will. Include multiple embodiments and enough detail that your non-provisional claims have room to maneuver.
- Draft at least three independent claims with different scope levels. One broad, one medium, one narrow. If the broad claim gets rejected, you have positions to fall back to without starting over.
- Budget for at least one office action response. The majority of patent applications receive at least one rejection. If you file expecting a clean approval, you will likely abandon when the first rejection arrives. Set aside $2,000 to $4,000 for a response, or use the USPTO Patent Pro Bono Program if you qualify.
- Study the examiner before you respond. Free tools like Patent Bots and Patexia publish examiner allowance rates by art unit. If your examiner allows 30% of applications, your response strategy needs to be different than if they allow 70%.
- Don’t abandon after one rejection. Office actions are part of the process, not a verdict. Large entities treat them as negotiations. Independent inventors should too.
Context and what to watch
The overall USPTO allowance rate has been trending downward slightly, dipping to 75% in the most recent real-time view as abandonment rates rise. That squeeze hits micro entities hardest because they are already at the bottom of the approval curve.
Meanwhile, the USPTO’s fee schedule was revised on April 1, 2026. Micro entities still get an 80% discount on most filing fees thanks to the Unleashing American Innovators Act. The fee savings are real. But a discount on fees does not help if your application never gets approved.
I expect this gap to widen further unless the USPTO introduces prosecution support specifically aimed at micro entity filers. The quality of the initial filing remains the single biggest lever independent inventors can pull.
Our Take
An 80% versus 40% gap is not a rounding error. It is a structural disadvantage baked into how the patent system rewards sophistication in prosecution, not just quality in invention. Independent inventors who treat patent filing as a one-shot lottery are feeding those numbers. The ones who study examiner data, draft with fallback positions, and budget for office action responses can close a meaningful portion of that gap on their own.
