USPTO Raises the Micro Entity Income Limit: What Patent Applicants Should Check
An inventor who missed the micro entity income cutoff earlier this year may now have a reason to revisit it. Effective September 15, 2026, the USPTO increased the maximum qualifying gross income for the income-based micro entity discount from $251,190 to $262,380. The change can affect what an eligible applicant pays at the next patent-fee deadline.
It does not automatically convert a small entity into a micro entity, and it does not make every startup eligible. The useful question is whether the particular application qualifies when its next fee is paid. That requires looking beyond the founder’s salary to the inventors, earlier applications, and rights granted to other parties.
What changed in September 2026
The USPTO’s micro entity guidance identifies September 15 as the effective date of the new $262,380 ceiling. The prior $251,190 limit applied from September 9, 2025, through September 14, 2026. This is an update to an income threshold, not a blanket reduction in the agency’s fee schedule.
Micro entity status can provide an 80% reduction on most USPTO patent fees. That can make a meaningful difference to a filing budget, but it does not reduce attorney fees, drawing expenses, or every government charge. Our discussion of patent costs and budgeting explains why those expenses should be considered separately.
Match the payment date to the right income year
Under 37 C.F.R. § 1.29(a), the gross-income inquiry concerns the calendar year before the year of payment. For a fee paid in October 2026, the relevant income year is therefore 2025. The applicable ceiling is the one in effect when the fee is paid.
Consider a hypothetical sole inventor whose 2025 gross income was $260,000. That amount exceeded the old ceiling but falls below the new one. If the application satisfies every other condition, the threshold change may allow that inventor to establish micro entity status before the next payment. The same result does not follow if a joint inventor’s relevant gross income is $270,000: one qualifying inventor cannot cure another inventor’s failure to meet the income requirement.
Do not substitute take-home pay or adjusted gross income for the required gross-income measure. If the tax records are complicated, resolve the calculation before signing a certification. A near-threshold case deserves a documented answer, rather than an estimate based on monthly payroll deposits.
Income is only one part of eligibility
The gross-income route also requires small entity qualification and compliance with the prior-application limit. The rule generally looks for no more than four previously filed applications naming the relevant person as an inventor, subject to specified exclusions. Provisional applications, foreign applications, and certain international applications are excluded from that count. Certain applications assigned because of previous employment are also treated differently.
This is a count of relevant applications, not simply issued patents. A useful intake record should identify application numbers, filing types, inventors, and former-employer assignments. Someone who says “I have only one patent” may still have several earlier filings that need to be considered.
Ownership arrangements matter as well. A low-income inventor may have assigned or licensed rights, or promised to do so, to a party that defeats eligibility. The review should therefore include employment agreements, assignments, and licenses—not merely the applicant name shown on the filing receipt. Tucker Law’s patent licensing practice addresses the rights and continuing obligations that those agreements create.
There is also a separate institution-of-higher-education route under § 1.29(d). Its conditions differ from the gross-income route. A university connection should prompt a review of that provision, rather than an assumption that the $262,380 ceiling answers every eligibility question.
A certification is not a permanent fee entitlement
The regulation separates establishing status from continuing to qualify for a discounted payment. A certification generally need not be filed again for every fee in the same application, but eligibility must remain appropriate on the payment date. Related applications require their own status analysis and certification where micro entity treatment is sought.
For a business, the practical solution is to connect the fee calendar to the people who know when income, inventorship, ownership, or licensing facts change. A docketing reminder alone cannot tell the person paying the fee that a license was signed last month.
| Record to review | Practical question |
|---|---|
| Prior-year income information | Has each relevant person or entity been checked against the current ceiling? |
| Application history | Have counted filings and claimed exclusions been identified? |
| Assignments and licenses | Has a new agreement changed who holds, or is entitled to receive, rights? |
| The individual application file | Is the required certification present, and does the next payment still qualify? |
This review belongs in the broader patent application strategy. For example, a founder preparing a new filing while negotiating a commercial license should tell prosecution counsel about both events. Treating the license and fee payment as unrelated administrative tasks can leave the fee decision based on outdated facts.
If the previous fee treatment was wrong
A later increase in the ceiling does not by itself establish that an earlier discounted payment was proper. Review the facts and requirements applicable to that payment separately.
Section 1.29(i) requires notification of lost entitlement before or with the next fee after micro entity status is no longer appropriate. Simply paying a higher amount is not sufficient notice. Section 1.29(k) provides a correction procedure for qualifying good-faith errors, with application-specific itemization and deficiency payments. That procedure should be evaluated against the actual payment history; it is not a reason to continue using an unsupported discount.
Keep copies of the certification, the eligibility review, and relevant changes with the patent records. If an error is discovered, a clear timeline makes it easier to identify affected payments and the appropriate response.
Use the new limit to make a better filing decision
The September change is a useful opportunity to revisit eligibility, especially where income fell between the old and new ceilings. It should also prompt a fresh look at an existing portfolio before the next payment, even if nobody is preparing a new application.
