Completing an Intent-to-Use Application: A Statement of Use Checklist

Intellectual Property > Trademark Registration | Published 4 September 2025 - Updated 21 December 2025 | UpLaw - uplaw.us

An intent-to-use application lets you plant a flag on a brand before a single sale, freezing nationwide priority as of your filing date. But a Notice of Allowance is a permission slip, not a diploma. This checklist governs the stretch where reserved rights are most often lost — the Statement of Use, its extensions, and the arithmetic that keeps the whole thing from expiring underneath you.

Keywords: statement of use, SOU, intent-to-use application, notice of allowance, amendment to allege use, request for extension of time, constructive use, Section 1(b), Section 1(d), 15 U.S.C. 1057(c), 36-month deadline, request to divide, specimen of use, dates of first use, bona fide intent, insurance extension, USPTO

Why this phase decides whether the whole application was worth it

Most of the money, effort, and anxiety in a trademark application go into the front half: picking a mark that can be protected, clearing it against senior rights, drafting the identification of goods, and surviving examination. By the time the U.S. Patent and Trademark Office issues a Notice of Allowance (NOA) on an intent-to-use (ITU) application, the applicant has already won the hard-fought battles. The examiner has signed off. The opposition window has closed. The mark has been found registrable in every respect but one — it is not yet in use.

That last inch is where ITU applications die. Not because the law is subtle, but because the completion phase is a calendar problem dressed up as a legal one, and calendars are unforgiving. The Statement of Use (SOU) and the extension requests that buy time for it run on strict, self-executing deadlines. Miss one, and the application goes abandoned; the reserved priority evaporates; and the filing date that would have anchored nationwide rights becomes a historical footnote. There is no gentle revival mechanism and no examiner discretion to lean on. The clock simply runs out.

This checklist is built for that phase. It assumes you have an allowed ITU application under Section 1(b) of the Lanham Act, 15 U.S.C. § 1051(b), and need to carry it across the finish line — either by proving use now or by lawfully buying time until you can. It expands the bare mechanics into the doctrine underneath them: what "use in commerce" actually requires, what a specimen has to show, how the six-month extension cadence works and where its ceiling sits, when to divide an application instead of deleting goods, and how the constructive-use rule of 15 U.S.C. § 1057(c) converts a paper filing date into a real, enforceable priority right. For the earlier stages, pair this with the intent-to-use filing guide and, for the front-end mechanics, the checklist for preparing a USPTO application. This resource is educational and is not legal advice; confirm current USPTO fees and deadlines at USPTO.gov.

How to use this checklist

Work the phases in order, but read Phase 1 first no matter where you think you are. The single most common wasted filing in ITU practice is an Amendment to Allege Use submitted during the window when the rules forbid it, or a Statement of Use filed when the mark is not yet genuinely in use on everything the application claims. Both mistakes are avoidable by correctly locating yourself in the lifecycle before you touch a form.

Each phase carries three things: a set of checkboxes for the operational steps, a Why it matters note that supplies the doctrine and the authority, and — where the concept is slippery — a clearly labeled hypothetical. The hypotheticals are invented illustrations, not real cases. Treat the checkboxes as necessary but not sufficient: the boxes tell you what to do, and the prose tells you why doing it wrong is fatal.

The ITU lifecycle at a glance

Before the phases, a map. An ITU application travels a longer road than a use-based one, because it splits the "is this registrable?" question from the "is this actually in use?" question and answers them at different times.

1. File the ITU application under § 1(b), asserting a bona fide intent to use the mark, and lock in the filing date.
2. Examination. The examining attorney reviews the application; refusals are litigated by office-action response.
3. Approval for publication, then publication in the Official Gazette for opposition.
4. Opposition window (30 days, extendable). If nobody successfully opposes, the application is allowed.
5. Notice of Allowance issues. This is the trigger for everything in this checklist. The SOU clock starts on the NOA issue date.
6. Statement of Use (or a Request for Extension of Time to file one) must be filed within six months of the NOA.
7. Registration issues once an acceptable SOU is examined and approved.

The reason the lifecycle matters operationally is that the instrument you use to prove use depends entirely on where you are in it. That is Phase 1.

Phase 1 — Locate yourself in the lifecycle before you file anything

• [ ] Confirm the application cleared examination and the opposition period and that the USPTO issued a Notice of Allowance — and note the NOA issue date, because that is the date the SOU clock starts.
• [ ] Read the NOA against the application file and confirm the listed goods and services, the classes, and the owner name are correct. Report any error to the USPTO's ITU/Divisional Unit promptly.
• [ ] Determine, honestly, whether you have begun bona fide use of the mark in commerce on the listed goods and services — all of them, or only some, or none.
• [ ] If use began before the application was approved for publication, you may already have been able to file an Amendment to Allege Use (AAU); after the NOA, the vehicle is the Statement of Use.

Why it matters. The NOA is not a registration. It is the USPTO's formal statement that the mark has "been cleared for registration" and would register but for the lack of proof of use. See generally 15 U.S.C. § 1051(b), (d); TMEP §§ 1103–1109. Treating the NOA as the end of the road — filing it away as though the mark were registered — is the most consequential misunderstanding in this area, because it silently starts a six-month clock the applicant never calendars.

The NOA is also where you catch clerical damage before it hardens into a defective registration. If the goods, the class, or the owner is wrong on the NOA, counsel should notify the ITU/Divisional Unit immediately, ideally by phone or fax, and follow the correction procedure in TMEP § 1106.04. An error left uncorrected here propagates into the registration certificate and can require a costly post-registration fix later.

Hypothetical — the filed-and-forgotten NOA. A founder files an ITU application for LUMENHAUS covering "smart home lighting fixtures" in Class 11, survives examination, and receives an NOA in March. Delighted, she prints the notice, tells her investors the mark is "registered," and turns back to product development. Nineteen months later, shipping her first units, she asks counsel to send a cease-and-desist to a copycat — and learns the application went abandoned the previous September because no SOU or extension was ever filed. The filing date she thought protected her is gone. A competitor who launched a similar LUMEN-HAUS product in the interim now has superior rights in its trading area. The mark was never registered; the NOA was a permission slip she mistook for a diploma. Everything in this checklist exists to prevent that outcome.

Phase 2 — Choose the right instrument: SOU, AAU, and the blackout window

An ITU applicant proves use with one of two instruments, and they are distinguished not by their content — which is identical — but by their timing.

• [ ] If the mark is already in use during examination, before the application is approved for publication, prove use with an Amendment to Allege Use under 37 C.F.R. § 2.76.
• [ ] If the mark comes into use after the Notice of Allowance issues, prove use with a Statement of Use under 37 C.F.R. § 2.88.
• [ ] Recognize the blackout period — after approval for publication but before the NOA issues — during which neither the AAU nor the SOU may be filed. If use begins during the blackout, wait for the NOA and then file the SOU.

Why it matters. The AAU and the SOU carry the same four elements — a per-class fee, a specimen, dates of first use, and a verified declaration of use. What differs is the window. The Lanham Act permits an allegation of use before the mark is approved for publication (the AAU) or after the NOA (the SOU), but it deliberately closes the door in between, while the application is in the pipeline toward publication and the opposition period. That gap is the "blackout." Filing an AAU into the blackout produces a rejected filing and a lost week or two — annoying, not fatal, but entirely avoidable if you know which instrument matches your moment.

The practical upshot: if you happen to start selling under the mark early — during examination — the AAU lets you short-circuit the whole extension apparatus and head straight for registration. If you start selling during the blackout or later, the SOU is your only vehicle, and the six-month NOA clock governs. Either way, knowing where you sit spares you a bounced filing. For a fuller treatment of the ITU system as a whole, see the intent-to-use filing guide.

Phase 3 — Assemble the Statement of Use, element by element

The SOU is filed electronically through the USPTO's Trademark Center (successor to the legacy TEAS Statement of Use / Amendment to Allege Use form). It has four load-bearing elements, and each must be satisfied per class. Get one wrong and the examiner issues an office action; get the declaration wrong and you risk a fraud or non-use challenge to the eventual registration.

• [ ] Filing fee for each class of goods or services covered by the SOU. Confirm the current per-class amount on the USPTO fee schedule; the 2025 fee restructuring changed several trademark fees, so do not rely on a number you memorized two years ago.
• [ ] At least one specimen per class showing the mark as actually used in commerce on those goods or services. See the checklist for preparing specimens that pass examination.
• [ ] Dates of first use for each class — both the date of first use anywhere and the date of first use in commerce.
• [ ] A verified declaration (the § 1(d) allegation) that the mark is in use in commerce on or in connection with all the listed goods and services, signed by a person authorized to bind or speak for the owner.
• [ ] File within six months of the NOA issue date, unless a valid extension request is on file.

Element 1 — The per-class fee

Trademark fees are charged by class, not by application. An SOU that covers three classes owes three SOU fees. If you have deleted goods down to a single class, you owe one. Budgeting the completion phase means anticipating not just the base SOU fee but the extension fees that stack up if use is slow (Phase 5) and any divide fees if you split the application (Phase 6). For how class count drives cost across the whole registration, see the checklist on classifying goods and services and the explainer on how the 45 Nice classes shape fees and scope.

Element 2 — The specimen

The specimen is a real-world sample of how the mark is used in the marketplace — the single most heavily litigated element of the SOU, because it is where paper meets practice. The governing rule is that the specimen must show the mark as actually used in commerce in connection with the goods or services in that class, and the reproduction must show enough to identify the specimen, the mark, and the goods or services. 37 C.F.R. § 2.56(c).

• [ ] For goods: a label, tag, container, or point-of-sale display showing the mark on or associated with the product. A label or tag detached from the goods should carry the informational matter that ordinarily accompanies that product — net weight, UPC code, ingredients — so the examiner can see it is a real commercial label and not a mockup.
• [ ] For services: an advertisement, brochure, webpage printout, menu, letterhead, or invoice showing the mark used in the sale or advertising of the service, with the service identified.
• [ ] Confirm the mark on the specimen matches the mark in the drawing. A material mismatch — different wording, a different design, a stylization that changes the commercial impression — draws a specimen refusal.
• [ ] Avoid merely prospective specimens: a "coming soon" page, a pre-sale ordering screen for goods not yet available, or advertising for a service not yet offered does not show use in commerce.

Why it matters. The USPTO generally requires only one specimen per class even where the class contains many goods, but the examining attorney may demand more if the class is broad, the items are unrelated, the specimen is of an unusual type, or the submitted specimen is insufficient — for instance, where the mark on the specimen differs from the drawing, or the specimen is prospective rather than in-use. If there is any doubt about a specimen's sufficiency, counsel should explain it in the description-of-specimen or miscellaneous-statement field and consider submitting extras. Keep in the file specimens for as many listed goods and services as possible, even those not submitted, because a use audit or a later challenge may demand proof for items the examiner never questioned. For the deeper treatment of what counts and why specimens fail, see the specimen checklist linked above.

Hypothetical — the mockup that wasn't use. A coffee roaster files an ITU for RIVERSTONE covering "roasted coffee beans" in Class 30 and, when the NOA arrives, submits as its specimen a glossy brand-guidelines PDF showing the RIVERSTONE logo on a bag design. The examiner refuses: a design comp prepared by the brand agency is not a sample of the mark as used in commerce on goods actually sold. The roaster substitutes a photograph of a filled, sealed retail bag on the shelf at a market — mark visible, net weight printed, priced and for sale — and the refusal is withdrawn. The lesson is that a specimen documents commerce, not intention; it must show the mark doing its job in the actual stream of trade.

Element 3 — Dates of first use

The SOU must state, for each class, two dates: the date of first use anywhere and the date of first use in commerce. They are frequently the same, but not always. A brand might use a mark on goods sold only abroad before it makes its first qualifying U.S. sale, in which case the "anywhere" date precedes the "in commerce" date. See TMEP §§ 903.01, 903.03.

• [ ] Record the first date the mark was used anywhere on the goods or services.
• [ ] Record the first date the mark was used in commerce — commerce that Congress may regulate.
• [ ] Confirm both dates against real records — invoices, shipping documents, screenshots with timestamps — and never round them backward.

Why it matters. "Commerce" under the Lanham Act means all commerce Congress may lawfully regulate: interstate commerce, commerce between the United States and a foreign country, and even intrastate commerce that affects interstate or foreign commerce. 15 U.S.C. § 1127; TMEP § 901.03. The breadth of that definition is a gift — most genuine commercial activity qualifies — but it is not a license to invent an early date. Dates of first use are sworn facts. Backdating them to gain a priority edge is not a rounding error; it is a false statement in a verified filing that can support a fraud claim and void the registration. Because the ITU applicant already enjoys a constructive-use priority tied to the filing date (Phase 9), there is rarely any real incentive to shade first-use dates — which makes doing so both dishonest and pointless.

Element 4 — The verified declaration

The heart of the SOU is the applicant's sworn statement: that it believes it is the owner of the mark, that the mark is in use in commerce, and that it is used on or in connection with the goods and services listed in the NOA, together with the dates of first use.

• [ ] Confirm the mark is actually in use in commerce on all listed goods and services before signing — or first delete or divide out the unused items (Phase 6).
• [ ] Have the declaration signed by a properly authorized person: someone with legal authority to bind the owner (an officer or general partner), a person with firsthand knowledge of the facts and actual or implied authority to act, or an attorney with an actual or implied power of attorney. 37 C.F.R. § 2.193(e)(1); TMEP § 611.03(a).
• [ ] Prefer a client representative with firsthand knowledge over outside counsel as the signatory.

Why it matters. The declaration is the document that later gets tested. If the mark was not in use on all the listed goods when the declaration was signed, the registration is exposed to cancellation for non-use or, worse, for fraud. That is why the "delete or divide" decision in Phase 6 is not a formality: you must trim the goods to match reality before you swear that everything is in use. And there is a quieter tactical reason to prefer a client officer over the attorney as signatory. If the application is later challenged and the declaration's truthfulness is contested, the signatory may be called as a witness. An attorney-signatory who becomes a witness may face disqualification from representing the client in that very dispute. Let the person who actually knows the facts swear to them.

Phase 4 — When you are not yet using the mark: the extension cadence

Most ITU applicants reach the NOA before they reach the market. The Lanham Act anticipates this and lets an applicant buy time in six-month increments — up to a hard ceiling. This is the arithmetic that trips people up, so work it carefully.

• [ ] If the mark is not yet in use on all listed goods when the SOU deadline approaches, file a Request for Extension of Time to File a Statement of Use, with the per-class fee, before the current period expires.
• [ ] Include in the first extension request a verified statement of continued bona fide intent to use the mark, reaffirming the representations from the original application. 37 C.F.R. § 2.89(a); TMEP § 1108.02.
• [ ] For a second or subsequent extension, additionally show good cause — a statement of ongoing efforts to use the mark, or a satisfactory explanation for the absence of such efforts.
• [ ] Stack extensions in six-month increments up to a maximum of 36 months from the NOA — the initial six-month SOU period plus up to five six-month extensions.
• [ ] Calendar every six-month deadline and every interim reminder. There is no easy revival for a missed SOU or extension.

Why it matters — the 36-month ceiling is absolute. Do the math once and it sticks: 6 months (the initial SOU period) + 5 × 6 months (the maximum extensions) = 36 months from the NOA. 15 U.S.C. § 1051(d)(1)–(2); 37 C.F.R. § 2.89; TMEP § 1108. An applicant who has not achieved and proven genuine use within that three-year window loses the application — and with it the reserved priority. The ceiling cannot be extended for hardship, and the USPTO will not toll it because a product launch slipped. The ITU route is a generous head start, but it is a head start with a shot clock.

The good-cause showing after the first extension

The first extension is nearly automatic: file the request, pay the fee, reaffirm your bona fide intent. Every extension after that requires a real showing of good cause, meaning a statement of the applicant's ongoing efforts to bring the mark into use for the goods and services covered. 15 U.S.C. § 1051(d)(2); TMEP § 1108.02(f). Merely asserting that "efforts are ongoing," without saying what they are, is not enough.

• [ ] Document and describe concrete efforts, which the USPTO treats as acceptable good cause, such as:
  • [ ] Product or service research and development;
  • [ ] Market research;
  • [ ] Manufacturing activities;
  • [ ] Promotional activities;
  • [ ] Steps to acquire distributors, obtain required governmental approval, or secure funding.
• [ ] Do not rely on excuses the USPTO has expressly rejected as good cause, including:
  • [ ] Physical illness or disability; and
  • [ ] Lack of staff or resources due to an economic downturn.

Why it matters. The good-cause requirement is the statutory pressure valve that keeps the ITU system from becoming a mark-warehousing scheme. Congress did not want applicants parking marks indefinitely on nothing but a fee and a promise. So after the first free pass, you must show the machine is actually moving toward market. The categories above track TMEP § 1108.02(f). The rejected excuses are worth memorizing because they are the ones applicants most naturally reach for — and they will not work. Note also that the good-cause showing dovetails with the bona-fide-intent evidence you should already be building (Phase 7): the same R&D records, vendor communications, and marketing plans that demonstrate good cause also fortify the underlying intent that a challenger might later attack.

The insurance extension — a safety valve worth knowing

• [ ] When filing the SOU near the deadline, consider filing an insurance extension request together with or just after the SOU, to preserve extra time to cure any deficiency the examiner flags.
• [ ] Understand its limits: the insurance extension must be filed during the six-month period in which the SOU was filed, may be filed only once, and must meet all the requirements of an ordinary extension request, including the fee. TMEP § 1108.03.

Why it matters. Imagine you file the SOU on the last day of a six-month period, and the examiner later rejects the specimen. Without an extension on file, the period has already closed, and there may be no time left to submit a substitute specimen — the application abandons on a curable technicality. The insurance extension buys a cushion: by filing it alongside the SOU, you keep a live window open in which to fix a defective filing. It is cheap insurance against a fatal timing squeeze, and experienced counsel use it routinely when filing an SOU late in a period.

Hypothetical — the specimen refusal that didn't kill the mark. A cosmetics startup files its SOU for VELVETINE on the final day of its second extension period, attaching a webpage specimen. Anticipating trouble, counsel files an insurance extension the same day. Six weeks later the examiner refuses the specimen as prospective — the page took pre-orders for a product not yet shipping. Because the insurance extension kept a period open, the startup swaps in a photo of a filled, shipped retail box and its accompanying invoice, curing the defect with room to spare. Had counsel not filed the insurance extension, the refusal would have landed after the deadline, and the application would have abandoned on a fixable problem.

Phase 5 — Handle partial use: delete or divide

Reality rarely cooperates with the identification of goods. Applicants routinely reach the SOU stage using the mark on some of the listed goods but not all. When that happens, you have two clean options — and a forbidden third.

• [ ] If the mark is in use on some but not all listed goods or services, choose between:
  • [ ] Delete the unused goods and file the SOU only on what is genuinely in use; or
  • [ ] File a Request to Divide, splitting the in-use goods into a child application that can register now while the unused goods stay in the parent under continued extension.
• [ ] Never swear an SOU covering goods the mark is not actually used on. That is a false declaration.

Deleting goods

Deleting is the simpler path. When you file the SOU, you amend the application to drop any goods or services for which the mark is not in use and for which you no longer have a bona fide intent to use it. There is no separate USPTO fee for deletion, and the SOU form makes it straightforward.

Why it matters. An applicant who leaves in goods that use does not support hands a challenger a ready-made non-use or fraud argument, and invites trouble under the USPTO's post-registration proof-of-use audit program later in the mark's life. Pruning deadwood before you swear the declaration is basic hygiene — it keeps the sworn statement true. For how that same discipline recurs at the maintenance stage, see the Section 8 continued-use checklist and the broader maintenance and renewal checklist.

Dividing the application

Dividing is the sophisticated path. A Request to Divide (TMEP § 1110) carves the in-use goods into a separate child application that carries the original parent filing date and can proceed to registration immediately, while the not-yet-used goods remain in the parent, still riding the extension timeline.

• [ ] Weigh dividing when you need a registration certificate now — for enforcement, licensing, a Customs recordation, or settlement leverage in a dispute — but the rest of the product line has a real, near-term launch plan.
• [ ] Account for the costs: dividing carries USPTO fees that depend on the number of child applications, and you now have two files to docket instead of one.
• [ ] Remember that dividing does not extend any deadline. The parent's existing SOU/extension deadlines stay exactly where they were. TMEP § 1110.07.

Why it matters. The child application's inheritance of the parent's filing date is the whole point: you do not sacrifice priority to register early. That makes dividing genuinely valuable when a certificate unlocks something time-sensitive — recording the mark with Customs to stop counterfeit imports, satisfying a licensee who needs a registration number, or gaining leverage in a TTAB or federal-court dispute. But it is not free, and the parent's clock keeps ticking regardless. Divide when the in-use goods need to register now and the remainder has a credible path to market; otherwise, delete and keep it simple.

Hypothetical — dividing to arm an enforcement fight. A hardware company files one ITU for FORGEWORKS covering both "hand tools" in Class 8 (shipping now) and "power tools" in Class 7 (still eighteen months from production). A cluster of counterfeit FORGEWORKS hand tools appears on an import manifest, and the company wants to record its registration with Customs to seize the goods. It files a Request to Divide, splitting the Class 8 hand tools into a child application that registers within a couple of months and goes straight onto the Customs recordation, while the Class 7 power tools ride out their extensions in the parent. The company gets an enforceable certificate on the goods it actually sells, keeps its early filing date for both, and does not perjure itself by claiming use on power tools that do not yet exist.

Phase 6 — Defend the bona-fide-intent foundation

Everything above assumes the application rests on a genuine intent to use the mark. That assumption can be attacked — in an opposition, in a cancellation, or as a defense in litigation — and if the attack succeeds, the application or registration falls no matter how perfect the SOU paperwork. The completion phase is therefore also a documentation phase.

• [ ] Keep contemporaneous records of intent from the filing date forward: business plans, product-development notes, packaging mockups, marketing budgets, and communications with vendors, manufacturers, and retailers.
• [ ] Avoid the appearance of warehousing — filing on a sprawling list of goods you have no concrete plan to sell, or hoarding marks to block competitors.
• [ ] Remember that the bona-fide-intent requirement reaches § 44 and § 66(a) applications too, not only § 1(b) ITU filings.

Why it matters. Bona fide intent is judged objectively, on the totality of the circumstances, not by the applicant's private say-so. The Federal Circuit made this concrete in M.Z. Berger & Co. v. Swatch AG, 787 F.3d 1368 (Fed. Cir. 2015), holding that an applicant's intent must be "firm" and demonstrable through objective evidence of circumstances showing an intention to use the mark in commerce — and affirming that the Board may find the requisite bona fide intent lacking where the record contains no documentary support beyond the application itself. The Sixth Circuit reinforced the point in Kelly Services, Inc. v. Creative Harbor, LLC, 846 F.3d 857 (6th Cir. 2017), addressing the consequences when an applicant lacks bona fide intent as to some of the goods listed in an application. The through-line is that a bare, uncorroborated assertion of intent — an application form and nothing else — can be fatal when an opposer puts intent in issue.

The reassuring corollary is that the very file you build to satisfy good cause on extensions (Phase 5) is the same file that defeats a bona-fide-intent challenge. R&D records, manufacturing steps, distributor outreach, funding efforts — that documentation does double duty. Think of the paper trail between filing and use as the evidentiary spine of the whole ITU: it is what converts a sworn intention into a defensible reserved right, and it is what makes the eventual SOU honest and audit-proof. For how intent, priority, and timing interlock at the front end, see the guide to timing a trademark filing and the overview of when to trademark a brand.

A related trap sits at the intersection of ITU applications and assignments. An ITU application generally cannot be assigned before an allegation of use is filed, except to a successor to the applicant's ongoing and existing business (or the portion to which the mark pertains). An assignment that violates that rule can void the application. If a corporate transaction touches an unperfected ITU application, handle it with care — see the checklist on recording a trademark assignment.

Phase 7 — After the Statement of Use

• [ ] Watch for the examiner's approval of the SOU. Once approved, the registration certificate typically issues within a couple of months.
• [ ] Review the registration certificate for errors — owner name, mark drawing, goods and services, dates — and report mistakes promptly.
• [ ] The day the registration issues, calendar the maintenance schedule: the Section 8 declaration of continued use (between the fifth and sixth years), the combined Section 8 and 9 renewal (before the tenth year and each decade after), and the optional Section 15 declaration of incontestability. See the maintenance and renewal checklist.

Why it matters. Approval of the SOU is the moment the ITU's reserved priority crystallizes into an actual registration — and the constructive-use date relates back to the original filing (Phase 9). But a registration is a use-it-or-lose-it right. The maintenance calendar begins immediately, and the discipline of matching the registration to actual use (deleting deadwood, keeping specimens current, avoiding naked licensing) never stops. For the operational sweep from filing desk to renewal, see the filing-desk prosecution checklist and the full registration-lifecycle checklist collection.

Phase 8 — The priority payoff: constructive use under Section 1057(c)

Everything in this checklist is in service of one prize, and it is worth naming plainly. When an ITU application matures into registration, the filing of that application is treated as constructive use of the mark, conferring nationwide priority as of the filing date — years before the applicant made a single sale. 15 U.S.C. § 1057(c). This is the reason to file an ITU at all, and the reason the completion phase is worth this much care.

• [ ] Understand that constructive use is contingent on registration. The priority is reserved by the filing date but only vests when the mark actually registers — which is exactly why finishing the SOU matters.
• [ ] Know the carve-outs in § 1057(c): the constructive-use priority yields to a party who, before the applicant's filing date, (1) used the mark, (2) filed an application to register it, or (3) filed a foreign application and is entitled to priority under § 44(d) based on it.

Why it matters. Constructive use inverts the ordinary common-law rule that the first to use a mark wins. Under pure common law, priority runs from actual use in a trading area; a later user in a remote area can carve out its own zone under the Tea Rose-Rectanus doctrine. The ITU applicant leaps over all of that: once registered, it holds nationwide priority as of its filing date, ahead of anyone who first used the mark after that date. That is a genuinely powerful right — see the deeper treatment in the constructive-use and nationwide-priority guide and the overview of what federal registration actually buys you. But the right is conditional. Reserved priority is not the same as vested priority. If the SOU deadline is missed and the application abandons, the mark never registers, § 1057(c) never triggers, and the whole edifice collapses back to common-law rules — where the person who actually sold something first wins.

Worked example — the priority race, start to finish. Two beverage startups both want HIGH TIDE for canned cocktails. In February 2025, Startup A files an ITU application under § 1(b) but does not launch until spring 2026. Startup B skips the paperwork and rushes cans to shelves in June 2025 — genuine, provable first use in commerce. Under pure common law, B's June 2025 use would beat A's later 2026 use, and B would own the mark. But A's February 2025 ITU filing, once it matures into registration, confers constructive use as of February 2025 under § 1057(c) — several months ahead of B's June sales. So A holds nationwide priority and can force B to stand down. The catch, and it is the whole point of this checklist: A captures that prize only if it completes the SOU (or stacks valid extensions and then completes the SOU) within the 36-month window and the application actually registers. If A lets a six-month deadline lapse in, say, October 2026 and the application abandons, the constructive-use date never vests, and B — the first to actually sell — wins on its June 2025 use. The ITU is a decisive head start. It rewards only the applicant who finishes the race.

Deadline math: a worked timeline

Because the completion phase is fundamentally a calendaring exercise, here is a fully worked timeline for a single-class application with a slow launch. Dates are illustrative.

• NOA issues: March 1, 2025. The six-month SOU clock starts.
• First deadline: September 1, 2025. File the SOU or a first extension request. Mark not yet in use, so file the first extension (reaffirm bona fide intent; pay the fee). No good-cause showing required.
• Second deadline: March 1, 2026. Still not in use. File the second extension — now good cause is required. Describe concrete ongoing efforts (manufacturing underway, distributor negotiations).
• Third deadline: September 1, 2026. File the third extension with good cause.
• Fourth deadline: March 1, 2027. File the fourth extension with good cause.
• Fifth deadline: September 1, 2027. File the fifth and final extension with good cause. This is the last one available.
• Final deadline: March 1, 2028 — 36 months from the NOA. The SOU must be filed by this date, proving genuine use in commerce. There is no sixth extension. If the mark is not in use and provable by now, the application abandons and the February-anchored priority is lost.

Two lessons fall out of the timeline. First, the "36 months" is measured from the NOA, and it is composed of one six-month SOU period plus five six-month extensions — count the extensions, not the calendar, and you will not miscount. Second, calendar not just the deadlines but a cascade of interim reminders (at least three months before each deadline is prudent practice), because the failure mode here is almost never a legal error — it is a docketing lapse.

Common mistakes

• Treating the Notice of Allowance as a registration. It is a permission slip. The mark is not registered until the SOU is approved and the certificate issues.
• Missing a six-month deadline, or filing an extension after the period has already closed. Both abandon the application, with no easy revival.
• Forgetting the 36-month hard cap. No extension, hardship, or explanation reaches past it.
• Filing an Amendment to Allege Use during the blackout period, after approval for publication but before the NOA, when the rules forbid it.
• Filing an SOU when the mark is not genuinely in use on all listed goods — instead of first deleting or dividing out the unused items — which exposes the registration to non-use and fraud attacks.
• Backdating dates of first use. A false statement in a verified filing, and pointless given the constructive-use priority the ITU already provides.
• Submitting a prospective or mismatched specimen — a mockup, a "coming soon" page, or a mark that differs from the drawing.
• Failing to file an insurance extension when filing an SOU late in a period, leaving no cushion to cure a specimen refusal.
• Neglecting to divide when a registration is urgently needed on the in-use goods and the rest of the line is still months from launch.
• Leaving no documentary trail of intent, so a later bona-fide-intent challenge under M.Z. Berger finds nothing but the application form.

Frequently missed edge cases

• The AAU shortcut. If use begins during examination, an Amendment to Allege Use can carry the application straight to registration without the NOA-and-SOU dance. Applicants who launch early sometimes forget the AAU exists and wait needlessly for an NOA.
• Different first-use dates. The date of first use anywhere can legitimately precede the date of first use in commerce — for example, where a mark was used on goods sold abroad before the first qualifying U.S. sale. Do not force the two dates to match.
• Good cause is not boilerplate. After the first extension, "efforts are ongoing" without specifics is insufficient. Illness, disability, and economic-downturn resource shortages are expressly rejected as good cause.
• Dividing does not toll anything. The parent application's deadlines survive a Request to Divide unchanged. Divide for the certificate, not for more time.
• Assignment restrictions on unperfected ITUs. An ITU application cannot be freely assigned before an allegation of use, except to a successor to the applicant's ongoing business. A stray assignment during an M&A deal can void the application.
• Bona fide intent reaches beyond § 1(b). Applications under § 44 and § 66(a) carry the same intent requirement, a point applicants relying on foreign priority sometimes overlook.
