Micro entity status allows qualifying patent applicants to pay reduced USPTO fees. Before claiming it, you must verify every applicant's eligibility, filing history, income, and obligations involving the invention.
Key Takeaways
- A qualifying micro entity generally receives an 80% reduction on eligible USPTO patent fees.
- The current verified USPTO gross income limit available for 2026 is $251,190 per relevant person.
- Applicants can qualify through the gross-income route or an association with a qualifying institution of higher education.
- Every applicant and named inventor must satisfy the requirements that apply to the selected route.
- Individual inventor status alone does not establish micro entity eligibility.
- You must certify status before paying a micro entity fee and reassess eligibility whenever another fee is due.
- Assignments, licenses, employer obligations, and related applications can change the correct entity status.
What Does USPTO Micro Entity Status Mean?
The USPTO places patent applicants into large, small, or micro entity fee categories. Entity status determines the amount charged for many filing, search, examination, issue, appeal, and maintenance fees. A large entity pays the standard amount. A qualifying small entity generally receives a 60% reduction, while a qualifying micro entity generally receives an 80% reduction on eligible fees.
Micro status is a fee classification under U.S. patent law, not a type of patent or business structure. Forming an LLC, operating as a sole proprietor, or filing an application in your own name does not automatically qualify you. If that distinction affects your application, review how an individual entity differs from a business entity and how an LLC is treated as a legal entity.
The legal definition appears in 35 U.S.C. 123 and 37 CFR 1.29. Under both available qualification paths, the applicant must first qualify as a small entity. Small entity status generally covers a person, qualifying small business concern, or nonprofit organization that has not transferred or promised patent rights to a party that does not qualify as a small entity.
Status applies separately to each application or patent. The same inventor or company can have micro status for one application and a different status for another because ownership, licensing, co-inventors, and contractual obligations can differ. Claim the category supported by the facts for the specific matter, not the category previously used elsewhere.
Current USPTO Micro Entity Gross Income Limit for 2026
The current verified USPTO micro entity gross income limit available for 2026 is $251,190. This amount is three times the reported median household income of $83,730. Because the USPTO updates the threshold after new income information becomes available, confirm the amount on the USPTO micro entity resource on the date you pay a fee.
For a fee paid in 2026, the gross-income test generally examines each relevant person's gross income for the preceding calendar year, meaning 2025. The income of each applicant and each named inventor must remain within the limit. The test is not based only on the startup's revenue, the invention's earnings, or the amount reported by the person signing the certification.
The income ceiling also applies to certain parties receiving or entitled to receive rights in the invention. Under the gross-income route, an applicant or inventor generally cannot have assigned, granted, conveyed, or become obligated to transfer a license or other ownership interest to an entity whose gross income exceeds the applicable limit. An agreement promising a future assignment can matter even if no assignment document has been recorded.
Do not rely on an older certification when paying a later fee. Income is measured using the period and limit applicable to the payment, so a person who qualified during filing may exceed the limit later. Keep the income records used for each determination, but do not submit tax returns or other confidential supporting records unless the USPTO specifically requires them.
2026 Micro Entity Status USPTO Requirements
There are two principal ways to qualify under 37 CFR 1.29. Meeting part of one route does not allow you to combine unrelated elements from both routes.
Gross-Income Basis
To claim status through the gross-income route, confirm all of the following:
- The applicant qualifies as a small entity under USPTO rules.
- Neither the applicant nor any named inventor has been named as an inventor on more than four previously filed patent applications, subject to the permitted exclusions.
- Neither the applicant nor any named inventor exceeded the applicable gross-income limit during the relevant preceding calendar year.
- No applicant or inventor has transferred, or is obligated to transfer, an interest in the application to a party exceeding the applicable income limit.
The prior-application count excludes foreign applications, U.S. provisional applications, and international applications for which the U.S. national-stage basic fee was not paid. It also excludes certain applications that a person assigned, or was obligated to assign, because of previous employment. Review the facts behind each earlier filing instead of assuming that every application shown in a patent search counts.
Institution of Higher Education Basis
The higher-education route also requires small entity status. In addition, the applicant must either obtain a majority of income from employment by a qualifying U.S. institution of higher education or have assigned, granted, conveyed, or become obligated to transfer an ownership or license interest to such an institution.
Employment by a university does not automatically satisfy the rule. The source of the applicant's income and the university's actual or promised rights both matter. Confirm that the organization meets the applicable definition of an institution of higher education and examine its employment, invention-assignment, sponsored-research, and technology-transfer agreements.
How Inventors, Assignments, and Licenses Affect Eligibility
Multiple-inventor applications require a person-by-person review. One inventor's excess income, application history, or transfer obligation can prevent the application from qualifying under the gross-income route. Adding or correcting an inventor may therefore change the analysis even when the invention and owner remain the same.
Assignments and licenses are equally significant. A founder may initially qualify while personally owning the application, then lose eligibility after assigning it to a company that cannot satisfy the relevant requirements. An option, promised license, merger provision, employment agreement, or investor contract may create an obligation to transfer rights before a formal assignment occurs. The entity's size and income are not interchangeable tests. Small entity status considers the recipient's small entity eligibility, while the gross-income micro test separately examines the statutory income ceiling.
Employer duties require special attention. Earlier applications assigned because of previous employment may fall within the exception to the four-application limit. A current obligation to assign the new invention, however, can affect both small entity and micro entity eligibility depending on the employer. University employment should be analyzed under the higher-education route rather than treated as an automatic exemption.
Ownership can also differ from business identity. A sole inventor, sole proprietorship, startup, nonprofit, and university may each face different facts concerning control and patent rights. Founders deciding how to hold an invention may also want to review the legal features of an individual business structure.
If eligibility depends on several inventors, prior applications, employer duties, assignments, university rights, or a pending ownership change, you can post your legal need on UpCounsel's marketplace. A patent attorney can review the rights and filing history, determine the proper entity status, and prepare or correct the necessary USPTO submission. Responses typically arrive within a day, helping you address the issue before the next fee is due.
Large, Small, and Micro Entity Status Compared
The correct category depends on who owns or controls the patent rights and which additional requirements are satisfied. The fee reductions apply only to fees for which the USPTO provides an entity-based rate.
| Status | Baseline Eligibility | Fee Treatment | Certification | Status-Change Duty |
|---|---|---|---|---|
| Large entity | Applicant does not qualify, or does not claim, small or micro status. | Pays the standard USPTO fee. | No reduced-fee certification is required. | Pay the standard rate unless a lower status is properly established. |
| Small entity | Qualifying person, small business concern, or nonprofit without disqualifying transfers or obligations. | Generally receives a 60% reduction on eligible fees. | Small entity status must be properly established under USPTO procedures. | Reassess before paying fees and pay the higher rate after entitlement ends. |
| Micro entity | Qualifies as a small entity and satisfies either the gross-income or higher-education route. | Generally receives an 80% reduction on eligible fees. | A written certification of micro entity status is required. | File notice when entitlement ends and do not continue paying micro rates. |
Do not choose a category solely because its fee appears in the electronic filing system. Payment at a reduced rate does not independently prove entitlement. Likewise, paying a large entity fee does not create micro or small entity status.
The practical difference extends beyond the initial filing fee. Search, examination, issue, appeal, extension, and maintenance fees may arise at different stages. The total impact therefore depends on the application type, prosecution history, and length of time an issued patent remains in force. Always consult the current USPTO fee schedule rather than relying on an old filing receipt or third-party fee chart.
How to Claim Micro Entity Status With the USPTO
Follow these steps before submitting a payment at the micro entity rate:
- Identify the applicant and owners. Confirm who currently owns the application and who is legally entitled or obligated to receive rights.
- Establish small entity eligibility. Micro entity status is unavailable unless the applicant first satisfies the small entity rules.
- Select one qualification path. Use either the gross-income basis or the institution-of-higher-education basis.
- Review every relevant person. Check each applicant and named inventor, not only the person handling the filing.
- Examine prior applications and contracts. Include employment agreements, assignments, licenses, options, sponsored-research terms, and agreements promising future rights.
- Use the current certification. Complete the USPTO certification that corresponds to the selected basis and follow its signature instructions.
- Submit the certification before or with the first micro fee. Do not pay the reduced amount first and assume a later filing will retroactively establish status.
The gross-income certification is commonly associated with PTO/SB/15A, while the institution-of-higher-education certification is commonly associated with PTO/SB/15B. Use the current versions and instructions available through the USPTO patent forms and certification resources. An authorized patent practitioner may sign in appropriate circumstances, but authorization and applicant status must be established under USPTO rules.
A certification ordinarily applies to the particular application or patent in which it is filed. A continuation, divisional, continuation-in-part, or reissue application is a separate matter and requires its own status determination and certification. Status established in a parent application does not automatically carry into the related filing.
Maintaining, Losing, and Correcting Micro Entity Status
You do not need to file a new certification with every payment in the same application merely because another fee is due. You must, however, determine that entitlement still exists whenever you pay a micro entity fee. The existing certification stops supporting reduced payments after the applicant ceases to qualify.
Reassess status when income changes, an inventor is added, ownership changes, or a new assignment, license, option, or contractual obligation arises. Also review status before an issue fee, extension fee, appeal fee, or maintenance fee. A separate certification is needed for a related continuation, divisional, continuation-in-part, or reissue application.
If entitlement ends, notify the USPTO as required and pay subsequent fees at the correct higher rate. Simply paying a small or large entity amount does not necessarily satisfy the requirement to notify the USPTO of a loss of micro entity entitlement. Keep dated records showing when the change occurred and which agreements or financial information were reviewed.
An erroneous payment should be addressed promptly. USPTO procedures allow certain status mistakes and fee deficiencies to be corrected through the required submission and payment of the amount owed. The necessary response depends on the application, the affected fees, and whether the error involved a good-faith mistake or a false representation. Do not assume that an underpayment will correct itself.
Maintenance-fee mistakes can place an issued patent at risk if the proper amount is not paid. If a patent has lapsed because of a missed or deficient payment, review how fee-related patent expiration works and obtain advice about any available USPTO petition procedure.
USPTO Micro Entity Fees, PCT Filings, and the EPO
Micro entity status reduces many USPTO patent fees, but not every patent-related cost. It does not reduce patent attorney fees, drawing charges, search-provider costs, translation expenses, or fees charged by foreign patent offices. Check each line of the current USPTO fee schedule because some charges may not have separate small and micro rates.
A U.S. provisional application can qualify for the micro entity filing rate when the applicant properly certifies eligibility. The same analysis applies before later U.S. nonprovisional fees are paid. Filing a provisional application does not count toward the four-application limit under the gross-income route, but it does not establish status for a later application.
Do not assume that U.S. micro entity status controls an international application. PCT fees involve separate rules, and only certain USPTO fees associated with a U.S. filing or national-stage proceeding may have entity-based rates. A PCT application for which the U.S. national-stage basic fee has not been paid is excluded from the prior-application count, but that exclusion is not a general PCT fee discount.
The European Patent Office also does not adopt an applicant's USPTO classification merely because the applicant qualified in the United States. Other patent offices may offer their own reductions under different definitions and procedures. Review the rules of each office before budgeting for an international patent strategy.
Frequently Asked Questions
Do Most Individuals Qualify for USPTO Micro Entity Status?
No, individual status alone does not show that most individuals qualify for USPTO micro entity status. Qualification depends on the applicant's small entity status, income, prior applications, co-inventors, and transfers or promised transfers of patent rights. There is no reliable basis for assuming that an individual inventor satisfies all of those requirements without a case-specific review.
How Much Does a Provisional Patent Application Cost?
The cost of a provisional patent application includes the current USPTO filing fee plus any professional, drawing, search, or document-preparation expenses. The government fee depends on the applicant's properly established large, small, or micro entity status. Because USPTO fees change, check the fee schedule in effect on the filing date rather than relying on an older quoted amount.
How Much Does It Cost to Get a Patent?
The total cost to obtain a patent varies with the invention, application type, number of claims, examination process, attorney work, drawings, and foreign filings. USPTO filing is only one stage. Search, examination, responses to office actions, issue fees, and later maintenance fees may add costs, so applicants should prepare a prosecution budget rather than focus only on the initial filing charge.
How Do I Get a Patent on a Product?
You start by documenting the invention, evaluating prior art, selecting the appropriate patent application, and preparing claims and drawings that describe the protectable features. Filing does not guarantee a patent. A USPTO examiner reviews the application for statutory requirements, including novelty and nonobviousness, and may issue objections or rejections that require a timely written response.
Can a Startup Claim Micro Entity Status After Raising Money?
A startup may still qualify after raising money, but the financing documents and resulting ownership structure must be reviewed. An investment can introduce assignments, licenses, control rights, or obligations involving a party that does not satisfy the relevant requirements. The amount raised by itself is not the only issue, and company revenue is not always the same as each person's statutory gross income.
Can I Request a Refund If I Paid a Higher USPTO Fee?
A later micro entity certification generally should not be treated as an automatic basis for recovering an earlier properly paid higher fee. Refund availability depends on USPTO rules, the type of payment, and when the request is made. Establish status before paying whenever possible, and check the USPTO's current refund procedures promptly if you believe a payment was made in error.
