A Canadian Guide to USPTO Micro Entity Status

For many Canadian startups, the United States Patent and Trademark Office (USPTO) has been, is, and will remain a critical and expensive jurisdiction for their IP portfolios. When you factor in the exchange rate, those official fees (i.e., filing, search, examination, and maintenance fees) hurt. The USPTO provides discounts for small (50%) and micro (80%) entities, but while the savings are enticing, they come with a time burden and risks. Are you playing it safe?

When scales change by two orders of magnitude, your practices should change. This is true for when you have micro entity status. — When scales change by two orders of magnitude, your practices should change. Microscopic image of coprimus mushroom.

The Allure of the Micro Entity Status

To put that 80% into perspective as of 2026/2027, a large entity pays roughly US$1,820 for the basic filing, search, and examination fees. A Micro Entity pays only US$364. Over the life of a single patent, including RCE, issue, and maintenance fees, the savings can easily exceed US$10,000.

For a Canadian company, that’s not just coffee money; it can really help an R&D budget or support a sales team.

Did Your Patent Agent Share This Option?

If your patent agent hasn’t mentioned Micro Entity status, it might not be an oversight; it might be out of caution; or it might be because you don’t qualify.

Some agents don’t know about the option.

Many agents don’t study the US system from the applicant’s perspective. They aren’t always aware of the details of acceleration or fee reduction programs.

Some agents are cautious.

A good agent protects the validity of your future patent. Since the criteria for micro entity status are specific, many agents are wary of the liability. If you claim status incorrectly, your patent could be challenged later for “inequitable conduct,” potentially rendering it unenforceable. Some agents apply the prudence used for small entity status in Canada to the US.

The qualifications

To qualify under the “Gross Income” basis, you must meet four strict criteria:

Small Entity Requirement: You must first qualify as a “Small Entity” (fewer than 500 employees).
The Filing Limit: Any inventor must not be named on more than four (4) previous U.S. non-provisional patent applications.
The Income Cap: No inventor or applicant had a gross income exceeding three times the median household income in the U.S. for the preceding calendar year.
No Assignment to “Large” Parties: You cannot have assigned or licensed the invention to an entity that doesn’t qualify for Micro Entity status themselves.

Traps

There are a few traps that an IP manager needs to be aware of.

Counting

How do you count employees? This isn’t an easy question. The field of HR analytics exists to address this problem. There are many nuances, including whether you should use headcount or FTE. Another issue is that in-house IP managers often meet resistance when requesting good data from HR. In which case, we say ask your coworker in finance.

Filing limit

All inventors must not be named on more than four (4) previous U.S. non-provisional patent applications. There is an exception if the inventor was under an obligation to assign the prior patent application; then it does count. However, this isn’t easy to prove unless you keep great records and are able to share them.

Income

Are any government contributions income? You want to be aware of this since in some cases it could be and in others it isn’t. Again, ask your colleagues in finance.

For individuals, their last year’s income matters.

Currency

The income cap is set in US dollars (USD). For Canadians, this means you must convert your CAD income to USD using the exchange rate from the last day of the relevant tax year. If the Loonie is weak, you might stay under the cap; if it’s strong, you might accidentally blow past it.

You can use the IRS – Yearly Average Currency Exchange Rates or the BOC – Annual Exchange Rates.

Signature Requirements

Oddly, while your company is the applicant, neither an officer nor a director can sign a declaration asserting micro entity status based on income. Your patent agent signs for you. This means you must answer some questions on behalf of the company.

Continual Need to Requalify

The biggest mistake applicants make is assuming that because they qualified at the time of filing, they qualify for the life of the US patent. This is false.

Continuous Verification: You must re-verify your status every single time a fee is paid.
The “Success” Problem: If your company grows or you license your tech to a large corporation, you lose micro entity status immediately in the latter case, permanently.
The Gross Income Creep: If your corporate income or an inventor’s personal income rises (perhaps due to the success of your business), the applicant or inventor may no longer qualify.

Best Practices

Understand the rules and track the needed data.

Understand the Rules

35 U.S.C. §41(h)(1) grants the USPTO Director the authority to establish regulations for reduced fees. Small entity status at the USPTO is defined primarily by 37 CFR §1.27, but also see 37 C.F.R. § 121.801ff. Micro entity status and the fee reduction are defined in 35 USC §123 and 37 CFR § 1.29. Also see MPEP §509ff. The needed form is SB15A.

That isn’t all of it. Most importantly, a patent agent, and by extension their partner in an IP manager, must make reasonable inquiry into the facts supporting an assertion of status. See 37 CFR §11.18(b)(2). If you make a non-good faith micro entity certification, you may be assessed a treble penalty under 35 U.S.C. §41(j) and §123(f). That is three times the amount you were to pay.

There is very little case law, but see Nesarikar v. USPTO, No. 2026-1167 (Fed. Cir. May 12, 2026) (nonprecedential).

Do You Have a Robust Tracking System?

If you are using Micro Entity status, you need more than just a spreadsheet. You need a protocol that answers:

Who is tracking the exchange rate for income conversion?
Is there a check-in before every maintenance fee payment?
Does the legal team know if a licensing deal has been signed that voids the status?

As a leader in a small company, you need to think differently.

The Bottom Line

The USPTO Micro Entity status is a fantastic tool for levelling the playing field for Canadian innovators, but it is not “free money.” It comes at the cost of constant auditing to ensure you don’t pay for those savings with the loss of your patent rights.

When in doubt, pay the Small Entity fee. A 50% discount that is “safe” is always better than an 80% discount that puts your entire intellectual property at risk.
