In brief. A trademark application is not one decision; it is several dozen, strung together over a year or more, where a single misstep—a guessed date of first use, a t-shirt logo too big to function as a mark, a missed three-month clock—can refuse, delay, or quietly kill the whole thing. These checklists turn that gauntlet into discrete, verifiable steps for every phase, from the clearance search you should run before you fall in love with a name through the Section 9 renewal you will file decades later. They are current as of the USPTO's January 18, 2025 overhaul (the TEAS Plus/Standard tiers are gone, replaced by one base application plus surcharges filed through the Trademark Center; the legacy TESS database is now the cloud-based Trademark Search) and the Trademark Modernization Act of 2020, which shortened most office-action response windows to three months and added new ways to attack registrations built on nonexistent use. Fees change—confirm current amounts at USPTO.gov before filing.


There is a particular flavor of regret known to anyone who has watched a beloved brand name die in examination. The product launched, the packaging printed, the website went live—and only then did the cease-and-desist letter arrive, or the office action citing a registration nobody bothered to look for. Federal trademark prosecution punishes optimism and rewards method. The good news is that almost every fatal error is preventable with a checklist used at the right moment.

This is that collection. It walks the full arc of a federal application: preparation and clearance, identification of goods and services, specimens, filing, examination, publication, the intent-to-use endgame, and the maintenance filings that keep a registration alive for as long as the mark is used. To keep the abstractions honest, the examples follow Trailhead Outdoor Co. (hypothetical), a small company registering its first marks—a fanciful brand name and a stylized logo—for hiking apparel and an outfitting-advice app.

A word on how to read this. Every checklist here is paired with the legal reasoning behind it, because a box ticked without understanding is a box ticked wrong. Where you want the narrative explanation in full, this collection complements our guide, How to File a Trademark Application with the USPTO: use that piece for the "why" at length and these checklists to execute the "how." It also has a sibling, USPTO Trademark Application Checklists: From Filing to Registration, which is the leaner, filing-desk companion focused on the mechanics from the moment you open the form forward; this article is the deeper, authority-rich version that starts a step earlier—at strategy and clearance—and carries the doctrine through. For the clearance step that precedes everything, see How to Conduct a Comprehensive Trademark Clearance Search. And because the intent-to-use path has enough wrinkles to deserve its own treatment, pair Part 7 below with Intent-to-Use Trademark Applications.

What changed—and why it matters. On January 18, 2025, the USPTO retired the TEAS Plus and TEAS Standard tiers and replaced them with a single base application at $350 per class, filed through the new Trademark Center. Three surcharges now do the work the old tiers used to: +$100/class for an application missing required information, +$200/class for using custom (free-form) goods/services language instead of the Trademark ID Manual, and +$200 per additional 1,000 characters of free-form text per class. Madrid Protocol (§ 66(a)) filings rose to $600/class. Separately, the Trademark Modernization Act of 2020 (Pub. L. No. 116-260, §§ 221–228), implemented at 86 Fed. Reg. 64300 (Nov. 17, 2021), reshaped prosecution: most office actions now carry a three-month deadline, extendable once to six for a $125 fee (37 C.F.R. § 2.62(a), (c), effective Dec. 3, 2022), and two new ex parte tools—expungement (15 U.S.C. § 1066a) and reexamination (15 U.S.C. § 1066b)—let third parties or the Director cancel registrations for marks that were never used. The through-line of every change is the same: the Office wants accurate, real, in-use registers, and it has made sloppiness more expensive.


Part 1: Pre-Filing Preparation Checklists

The cheapest trademark mistakes to fix are the ones you catch before filing. Once a serial number issues, your filing date, your identification, and your basis are largely locked in; an identification can be narrowed but never broadened, a mistaken owner cannot be swapped for the right one, and a void application cannot be resurrected. Preparation is where the leverage is.

Checklist 1.1: Is Your Mark Even Eligible? (The Distinctiveness Gate)

Before anything else, ask whether the law will let this mark onto the Principal Register at all. Trademark strength runs along a spectrum that has driven American trademark law since Abercrombie & Fitch Co. v. Hunting World, Inc., 537 F.2d 4 (2d Cir. 1976), and the spot a mark occupies on that spectrum decides almost everything that follows.

Question Yes No Action if No
Is the mark distinctive—fanciful, arbitrary, or suggestive—rather than merely descriptive of the goods/services? If merely descriptive, plan for a § 2(f) acquired-distinctiveness claim or the Supplemental Register; if generic, choose a different mark
Have you run at least a knock-out clearance search? Search before investing further (Checklist 1.2)
Is the mark clear of conflicting registrations and applications? Reassess the mark or develop distinguishing arguments
Is it clear of conflicting common-law uses? Assess risk; consider an alternative
Do you own rights to every element (design, photo, font, slogan)? License or remove the problematic element
If the mark names or depicts a living person, do you have written consent? Obtain consent (15 U.S.C. § 1052(c))
Could the mark be refused as primarily a surname, geographically descriptive, deceptive, or functional? Evaluate the § 2(e) and § 2(a) bars before filing
Is the matching domain available? Are key social handles available? Weigh the practical (not legal) consequences

The distinctiveness spectrum—your single most important predictor of success:

STRONGEST ◄──────────────────────────────────────────► WEAKEST

 FANCIFUL     ARBITRARY     SUGGESTIVE    DESCRIPTIVE      GENERIC
 (invented    (real word,   (hints at     (describes a     (the name

 Strong protection, immediate Principal  with proof of      registrable
 Register                                secondary meaning

The line that matters most in practice sits between suggestive and descriptive. A suggestive mark requires "imagination, thought, and perception" to connect it to the goods, while a descriptive term "immediately conveys" an ingredient, quality, characteristic, function, or feature. Compare In re Gyulay, 820 F.2d 1216 (Fed. Cir. 1987) (APPLE PIE for potpourri merely descriptive), with the imagination test articulated in In re Abcor Development Corp., 588 F.2d 811 (C.C.P.A. 1978). Examining attorneys lean on In re Chamber of Commerce of the United States, 675 F.3d 1297 (Fed. Cir. 2012), and In re Bayer Aktiengesellschaft, 488 F.3d 960 (Fed. Cir. 2007), for the "immediately conveys" formulation. If your mark is descriptive, you are not doomed—you are simply on notice that you will need acquired distinctiveness under § 2(f), 15 U.S.C. § 1052(f), or a fallback to the Supplemental Register. (For where those rights diverge, see Common Law Rights, the Supplemental Register, and the Principal Register.)

At the far weak end lies genericness, which no amount of investment can cure. A generic term—the name of the genus of goods itself—can never function as a mark. H. Marvin Ginn Corp. v. International Ass'n of Fire Chiefs, Inc., 782 F.2d 987 (Fed. Cir. 1986), supplies the genus/species, primary-significance test. And lest you assume a "generic.com" formation is automatically barred, USPTO v. Booking.com B.V., 591 U.S. 549 (2020), held there is no per se rule: if consumers perceive the whole as a brand, it can register. Aspirin and escalator are the cautionary tales of genericide—marks so successful they became the public's word for the thing and slid off the bottom of the spectrum.

Trailhead example. "Trailhead" for outdoor apparel is suggestive: it evokes hiking without describing shirts or jackets. That is a strong, inherently distinctive position—immediately registrable on the Principal Register, no secondary-meaning evidence required. Had the company chosen "DurableHikingGear," it would have walked straight into a § 2(e)(1) descriptiveness refusal and the slower § 2(f) road.

For the threshold strategic question of whether and when to file at all, see When to Trademark Your Brand and the foundational Trademark Basics.

Checklist 1.2: Clearance Search Completion

Filing without clearance is buying a lottery ticket and calling it a strategy. A search does two jobs: it surfaces § 2(d) likelihood-of-confusion conflicts that would draw a refusal, and it reveals senior common-law users whose unregistered rights can still block you or sue you. Counsel typically runs a quick knock-out search of the USPTO database first, then a full comprehensive search spanning federal, state, and common-law sources.

  • Searched USPTO Trademark Search (the cloud system that replaced TESS) for identical marks
  • Searched for phonetic equivalents (sound-alikes)
  • Searched for visual/spelling variants and foreign-equivalent translations
  • Searched for conceptually similar marks (synonyms, near-meanings)
  • Reviewed hits for relatedness of goods/services, not just identity of marks
  • Checked the live/dead status of each potential conflict
  • Searched relevant state trademark registers
  • Conducted a common-law search (web, industry directories, marketplaces)
  • Searched domain registrations and social-media handles
  • Documented methodology and results (this record can become good-faith evidence later)
  • Assessed overall clearance risk and made a documented go/no-go decision

That last point is worth dwelling on. A documented clearance search and a favorable attorney opinion are not just due diligence—they are a shield. A good-faith adoption built on competent clearance can defeat a later claim of willful infringement and the enhanced damages that ride with it. See The Shield of Good Faith: How Trademark Clearance Searches, Attorney Opinions, and USPTO Approval Can Protect Against Willful Infringement Claims. The flip side appears in Stone Creek, Inc. v. Omnia Italian Design, Inc., 875 F.3d 426 (9th Cir. 2017): knowledge of a senior user can destroy the good-faith defense entirely—see Stone Creek v. Omnia. For the full methodology, see How to Conduct a Comprehensive Trademark Clearance Search.

Checklist 1.3: Gathering Required Information

The base application has roughly twenty required information fields. Supply them all—and use ID-Manual descriptions—and you stay at the $350 base fee. Leave a required field blank and you trigger the +$100/class "missing information" surcharge under the 2025 rule, the modern analog of failing to qualify for the old TEAS Plus discount.

Applicant information. Get the owner exactly right; an application filed in the name of the wrong entity is void ab initio and cannot be saved by amendment or assignment. Collect the full legal name, entity type, state/country of organization (for entities), citizenship (for individuals), a street address (the domicile address cannot be a P.O. box), a monitored email for USPTO correspondence, and a phone number. Note the domicile rule: foreign-domiciled applicants—individuals residing outside the U.S. or entities headquartered abroad—must appoint a U.S.-licensed attorney (37 C.F.R. §§ 2.2, 2.11). Domestic applicants may file pro se (37 C.F.R. § 11.14(e)), though they rarely should.

Mark information. Decide the format: standard characters (protects the wording in any font, size, or color) or special form (protects a specific stylization, design, or color claim). If special form, prepare a clean image file and a written description of the mark; if color is claimed as a feature, prepare the color claim. If the mark contains foreign wording, prepare a translation; if it contains non-Latin characters, a transliteration.

Use information. Determine the filing basis (Part 4 below), and for any use-based class, pin down the actual date of first use anywhere and date of first use in commerce—the real dates, never guessed or rounded—and prepare a compliant specimen.

Field set Collected Note
Owner: legal name, entity type, state/country, citizenship Wrong owner = void application
Domicile address (no P.O. box) + monitored email Triggers correspondence and the foreign-attorney rule
Mark format decision (standard vs. special form) Standard characters are broader and usually preferred
Image file + mark description + color claim (if special form)
Translation / transliteration (if applicable)
Filing basis per class See Part 4
Dates of first use (use-based classes only) Real dates; supporting documents on file
Specimen prepared (use-based classes) See Part 3

Part 2: Goods and Services Identification Checklists

Your identification of goods and services is the legal perimeter of your registration—it defines what you can stop others from doing and, increasingly, what you are paying for. Under the 2025 structure it is also a fee lever: pull pre-approved language from the Trademark ID Manual and you avoid the +$200/class custom-identification surcharge; draft free-form prose and you pay it, plus another $200 for every extra 1,000 characters.

Checklist 2.1: Drafting the Identification

Step Done Note
Listed all goods sold/to be sold under the mark
Listed all services provided/to be provided
Pulled pre-approved descriptions from the ID Manual where possible Avoids the +$200/class surcharge
Made descriptions specific, not sprawling "Computer software for accounting," not "computer software"
Confirmed each item matches actual/intended business activity
Assigned the correct Nice class to each item TMEP §§ 1401–1402
Grouped items by class and counted classes Each class = one base fee
For use-based classes, confirmed the ID matches current use Overbroad use claims invite cancellation

Common classification quick reference (illustrative; always verify against the ID Manual):

Your business Likely class Example ID language
Downloadable software/app Class 9 "Downloadable mobile application software for …"
SaaS / hosted software Class 42 "Providing temporary use of non-downloadable software for …"
Clothing Class 25 "Shirts; pants; jackets; hats"
Restaurant Class 43 "Restaurant services; café services"
Retail / online retail Class 35 "Online retail store services featuring [goods]"
Consulting Class 35 "Business management consulting"
Educational services Class 41 "Educational services, namely, conducting classes in …"
Legal services Class 45 "Legal services"

A recurring trap: the same product can live in different classes depending on how it is delivered. Downloadable software is a Class 9 good; the identical functionality offered as a hosted service is a Class 42 service. Trailhead's hiking apparel sits in Class 25; its outfitting-advice app, if downloadable, sits in Class 9. Getting this wrong is not fatal—class can be corrected—but it costs time and sometimes fees. For a deeper tour of the system, see USPTO Trademark Classes.

Checklist 2.2: Identification Review (and the Void-for-Nonuse Trap)

Before you finalize, audit the identification against the criteria below. The stakes are higher than they look: if you claim use on goods you are not actually selling, you expose the registration to cancellation and to the TMA's new ex parte attacks. An application or registration can be held void as to goods or services for which the mark was not in use when use was claimed—the classic "void ab initio" nonuse defense, assertable within five years (15 U.S.C. § 1064; NetJets Inc. v. IntelliJet Group, LLC, 678 F. App'x 343 (6th Cir. 2017)). And as of the TMA, a statutory nonuse claim under Section 14(6), 15 U.S.C. § 1064(6), can be brought any time after the third year, with no need to prove intent to deceive.

  • Every item accurately describes what you actually sell or do
  • No item is broader than actual or intended use ("clothing" is too broad; "T-shirts" is fine)
  • Language is specific enough to clear examination
  • Items drawn from the ID Manual wherever possible
  • Class assignments correct; no obvious coverage gaps for the core business
  • Reasonable, genuine business expansions considered (not aspirational padding)
  • The identification supports the specimen you will submit
  • You are not claiming use on a single item you cannot prove you sell

Identification red flags:

Problem Example Fix
Too broad "Computer software" "Computer software for inventory management"
Too vague "Consulting services" "Business management consulting"
Wrong class Downloadable app placed in Class 42 Move to Class 9
Doesn't match use ID says "clothing"; you sell only hats Narrow to "hats"
Made-up jargon "Social media optimization solutions" Use recognized ID-Manual terminology
Padded for coverage Listing goods you "might" sell on a §1(a) basis File those goods under §1(b) instead

A clean way to have it both ways. If Trailhead currently sells shirts and hats but plans to add jackets next year, it should file the shirts and hats on a Section 1(a) use basis and the jackets on a Section 1(b) intent-to-use basis—rather than overclaiming current use. You can split bases within a single application by class and item (37 C.F.R. § 2.34(b)); you simply cannot claim both bases for the same goods.


Part 3: Specimen Preparation Checklists

Specimens are where good applications go to die. A specimen is the evidence that the mark is actually used in commerce as a source identifier—not merely conceived, designed, or advertised. The rules are technical, the refusals are common, and the USPTO has grown aggressive about fakes. The 2020 rules expressly added "a digitally created or altered image; a mockup; an artist's rendering; a printer's proof; [or] a computer illustration" to the list of unacceptable specimens, 37 C.F.R. § 2.56(c), and examiners now flag tell-tale signs of fabrication (floating text, pixelation, images identical to third-party goods) under TMEP § 904.04(a).

Checklist 3.1: What Counts as a Specimen, by Type

The single most important rule, and the one applicants violate most: mere advertising is not an acceptable specimen for goods. It is acceptable for services. The asymmetry traces to the statute's different conceptions of "use" for goods (the mark must appear on the goods, their packaging, or point-of-sale displays) versus services (the mark must be used in the sale or advertising of the services, with a direct association).

For goods (Classes 1–34):

Acceptable specimen Met?
Labels or tags affixed to the goods
Packaging or containers showing the mark
The goods themselves bearing the mark
Point-of-sale displays
A web page showing the mark, the goods, AND a way to order (add-to-cart / buy button)

For services (Classes 35–45):

Acceptable specimen Met?
Advertising that shows the mark and the services
A website using the mark while describing/offering the services
Brochures, signage, or letterhead used in rendering the services
Business cards—only if they show the services, not just a name

Checklist 3.2: Specimen Quality Verification

Requirement Verified
The mark on the specimen matches the mark in the drawing (no material alteration—In re Hacot-Colombier, 105 F.3d 616 (Fed. Cir. 1997))
The mark is legible and clearly visible
The specimen shows real use in commerce, not an internal prototype
The specimen ties the mark to the identified goods/services
For goods: mark appears on goods, packaging, labels, tags, or a point-of-sale display
For a goods website: an ordering mechanism is visible
For services: the specimen shows the mark in advertising or rendering the services
The mark is not used merely as ornamentation (see below)
Nothing is mocked up, digitally altered, or a printer's proof
File format acceptable (JPG, PNG, PDF) and from the correct (current) time period

Checklist 3.3: The Ornamentation Trap

The most counterintuitive specimen failure has nothing to do with fakery. A mark splashed large across the front of a t-shirt or coffee mug may be perceived by consumers as decoration, not as a source identifier—and a decorative use does not function as a trademark (TMEP § 1202.03). Size and placement control: a small logo on the breast pocket reads as a brand; the same logo blown up across the whole chest reads as a design. There is no fixed size rule (In re Lululemon Athletica Canada Inc., 105 U.S.P.Q.2d 1684 (T.T.A.B. 2013)), and the "secondary source" doctrine can sometimes rescue ornamental matter where the mark already identifies the applicant from other uses (In re Olin Corp., 181 U.S.P.Q. 182 (T.T.A.B. 1973)). But the safe move is a specimen showing the mark used in a clearly source-identifying way.

Run your specimen against these common rejection grounds:

  • NOT an invoice or packing slip standing alone
  • NOT a business card showing only a name (for services, it must show the services)
  • NOT a press release or news article
  • NOT a domain-name registration record
  • NOT a bare screenshot of goods with no ordering information
  • NOT a digitally altered, mocked-up, or composite image
  • NOT an internal document never shown to customers
  • NOT a foreign specimen (it must show use in U.S. commerce)
  • NOT ornamental/decorative use (mark as design, not source identifier)
  • The mark on the specimen is NOT materially different from the drawing

Trailhead example. Trailhead's first specimen for its apparel—a beautiful product photo of a jacket with the logo printed across the entire back—drew an ornamentation refusal. The fix was a second specimen: a photograph of the sewn-in neck label bearing the TRAILHEAD word mark, which unambiguously functions as a source identifier. For the app, a screenshot of the App Store listing showing the mark, a description of the app, and a "Get" button did the job.


Part 4: Filing Basis and Application Filing Checklists

With preparation done, you file through the Trademark Center. But before you touch the form, you must pick a filing basis, because the basis determines what you must prove now versus later.

Checklist 4.1: Choosing the Filing Basis

Every application must claim at least one basis. The four:

  • Section 1(a) — Use in Commerce (15 U.S.C. § 1051(a)). You are already using the mark in interstate commerce on all the identified goods/services. "Use" means bona fide use in the ordinary course of trade—not token use to reserve rights (15 U.S.C. § 1127). You supply dates of first use and a specimen at filing.
  • Section 1(b) — Intent to Use (15 U.S.C. § 1051(b)). You have a bona fide intent to use the mark but haven't started yet. You file now to secure an early constructive-use priority date and complete the use showing later via a Statement of Use (Part 7). See Intent-to-Use Trademark Applications.
  • Section 44 — Foreign Application/Registration (15 U.S.C. § 1126). For qualified foreign applicants relying on a home-country application (§ 44(d), for priority) or registration (§ 44(e), as a basis to register). A § 44 applicant need not prove U.S. use before registration, but should hold a bona fide intent to use.
  • Section 66(a) — Madrid Protocol (15 U.S.C. § 1141f). An extension of protection to the U.S. from an international registration; no pre-registration U.S. use required. Now $600/class.
Decision Yes Note
Are you using the mark in commerce on ALL identified goods/services now? If yes, § 1(a); if only some, split bases by item
Do you intend to use but haven't started? § 1(b); requires documented bona fide intent
Are you a foreign applicant with a home application/registration? § 44(d)/(e)
Are you extending a Madrid international registration to the U.S.? § 66(a), $600/class

A note on the constructive-use head start. Filing—on any basis—gives you a constructive-use priority date under 15 U.S.C. § 1057(c) that, upon registration, reaches back to your filing date nationwide against later adopters. That is the strategic engine of the intent-to-use system: you can stake a national claim before a single product ships. See Federal Registration Constructive Use 15 U.S.C. 1057(c).

For § 1(b) applicants, the bona fide intent must be more than a hope. The TTAB looks for objective evidence—business plans, product development, market research—and will find the intent lacking where the record is bare (Commodore Electronics Ltd. v. CBM Kabushiki Kaisha, 26 U.S.P.Q.2d 1503 (T.T.A.B. 1993)). Keep contemporaneous documentation of your plans.

Checklist 4.2: Base Application Fees and Surcharges (2025)

There is now one base application; your per-class cost depends on completeness and how you describe the goods/services.

Item Fee (per class)
Base application (§§ 1 and/or 44), ID-Manual descriptions, complete filing $350
Surcharge — missing required information +$100
Surcharge — custom (free-form) goods/services description +$200
Surcharge — each additional 1,000 characters of free-form text +$200
Madrid Protocol (§ 66(a)) application $600
Can you describe ALL goods/services using ID-Manual
language AND provide every required field at filing?

       YES  │  NO
            │    │

Checklist 4.3: Trademark Center Application Completion

Work through each section deliberately.

Owner information

  • Entity type correctly selected
  • Full legal name entered exactly as it should appear on the registration
  • State/country of organization (entities) or citizenship (individuals) correct
  • Domicile address complete (no P.O. box); foreign applicants have appointed U.S. counsel
  • Monitored email entered

Mark information

  • Standard characters selected if no design/color/stylization is claimed (broader protection)
  • Special form selected and a clean image uploaded if design/color/stylization is claimed
  • Color claim included if color is a feature; mark description provided for special-form marks
  • Foreign-word translation / transliteration provided if applicable
  • Literal element entered correctly

Goods/services

  • Every item entered with the correct Nice class
  • ID-Manual descriptions used where possible (avoids the +$200 surcharge)
  • A filing basis selected for each class

Basis (per class)

  • § 1(a): dates of first use entered (real dates) and specimen uploaded
  • § 1(b): bona fide intent verified and documented
  • § 44(d)/(e): foreign application/registration details entered
  • § 66(a): international registration details entered

Declaration

  • Signatory has authority to bind the applicant
  • Declaration reviewed for accuracy—false statements carry fraud and criminal exposure
  • Signature properly formatted (/Name/), with signatory name, position, and date

Fee

  • Total = base × classes, plus any surcharges; payment method ready

Sign with care. The declaration is sworn. Fraud on the USPTO requires a knowing, material misrepresentation made with the subjective intent to deceive, proven by clear and convincing evidence—the demanding standard set in In re Bose Corp., 580 F.3d 1240 (Fed. Cir. 2009), which rejected the looser "knew or should have known" test. That is a high bar, but it is not an invitation to be careless: inaccurate use dates or overclaimed goods are exactly the kind of thing that comes back to haunt a registration in a cancellation or audit.

Checklist 4.4: Pre-Submission Final Review

  • Proofread the mark exactly as entered—a typo here is the mark you get
  • Applicant name matches official formation documents
  • Goods/services read naturally and are accurate
  • Filing basis is correct for each class
  • Use dates are accurate (never guessed or rounded)
  • Specimen renders correctly in preview
  • Total fee (including surcharges) is correct
  • Saved a complete copy/screenshot of the application

Checklist 4.5: Post-Filing Immediate Actions

  • Recorded the serial number and saved the filing receipt
  • Calendared the office-action response window (3 months, extendable once to 6 for a fee)
  • Set a status-check reminder for ~3 months out (use TSDR)
  • Added the application to a docket/tracking system
  • Confirmed the correspondence email is monitored
  • Engaged a trademark watch service for confusingly similar new filings

Part 5: Examination and Office Action Checklists

Roughly two-thirds of applications draw at least one office action. An office action is not a rejection; it is a conversation the examining attorney has opened, and your job is to answer every point in it. Since December 3, 2022, the clock is shorter than it used to be: most office actions carry a three-month response deadline, extendable once to six months for a $125 fee (37 C.F.R. § 2.62(a), (c)). The old six-month default is gone for domestic-basis applications—a TMA change that catches the unwary. (Madrid § 66(a) office actions retain the six-month, non-extendable period.)

Checklist 5.1: Triage the Office Action

Step Done
Calendared the deadline (3 months; extension available once to 6 for a fee)
Identified whether it is non-final or final
Listed every refusal (substantive registrability bars)
Listed every requirement (formalities to correct)
Identified the statutory basis for each refusal (§ 2(d), § 2(e)(1), etc.)
For § 2(d): pulled and analyzed the cited registration(s)
For § 2(e)(1): assessed the strength of the descriptiveness position
For specimen refusals: pinpointed the specific deficiency
Decided whether an examiner interview would help
Chose a response strategy for each issue

Checklist 5.2: The Two Refusals You Will Actually Face

Likelihood of confusion — § 2(d), 15 U.S.C. § 1052(d). This is the most common substantive refusal. The Federal Circuit analyzes it under the thirteen factors of In re E.I. du Pont de Nemours & Co., 476 F.2d 1357 (C.C.P.A. 1973)—but not all thirteen matter in every case (In re Mighty Leaf Tea, 601 F.3d 1342 (Fed. Cir. 2010)). Two factors carry most of the weight: the similarity of the marks (in appearance, sound, connotation, and commercial impression) and the relatedness of the goods/services. Dissimilarity of the marks alone can be dispositive of no confusion. For how courts weigh confusion in litigation, see Navigating the Maze of Trademark Confusion.

Argument against a § 2(d) refusal Applicable? Evidence to marshal
Marks differ in sight, sound, meaning, or commercial impression Side-by-side comparison
Goods/services are unrelated Explanation; evidence of distinct uses
Different trade channels and classes of purchaser Channel/market evidence
Sophisticated, careful purchasers Purchase-conditions evidence (cf. Stone Lion Capital, 746 F.3d 1317 (Fed. Cir. 2014))
Cited mark is weak / crowded field Third-party registrations and uses
Coexistence agreement obtainable Contact the cited owner
Cited registration vulnerable (nonuse/abandonment) Evidence supporting cancellation

Mere descriptiveness — § 2(e)(1), 15 U.S.C. § 1052(e)(1). The examiner says the mark immediately conveys a quality or feature.

Argument Applicable? Evidence
The mark is suggestive, not descriptive Show the imagination/mental leap required
Claim acquired distinctiveness under § 2(f) Five-plus years of use, sales, advertising, surveys
Amend to the Supplemental Register Acceptance of narrower rights; still bars later confusingly similar marks

A § 2(f) claim leans on secondary meaning—proof that consumers have come to see the descriptive term as a brand. Five years of substantially exclusive and continuous use is prima facie evidence (15 U.S.C. § 1052(f)), but strong cases pair it with sales figures, advertising spend, and sometimes consumer surveys (Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763 (1992); Wal-Mart Stores, Inc. v. Samara Bros., 529 U.S. 205 (2000)).

Specimen refusals.

Issue Fix
Specimen doesn't show the mark Submit a substitute showing the mark
Mark on specimen differs from the drawing Conform the specimen or (carefully) amend the drawing
Wrong type of specimen Submit an acceptable type for the goods/services
Doesn't tie the mark to the identified goods/services Submit a specimen that does
Goods website lacks ordering information Submit a screenshot showing add-to-cart/buy
Ornamental use Submit a source-identifying use (label, tag, hangtag)

Checklist 5.3: Building and Filing the Response

  • Confirmed the deadline and whether an extension was filed
  • Researched the legal standard for each refusal (TMEP and TTAB precedent)
  • Gathered supporting evidence and prepared any substitute specimen
  • Drafted amendments (to the ID, drawing, basis, or register) if pursuing them
  • Considered an examiner interview before formal filing
  • Response addresses EVERY refusal and requirement—omitting one can sink the application
  • Arguments are backed by evidence or legal authority
  • Declarations attached where factual assertions require verification
  • Response signed and filed before the deadline; receipt saved
  • Calendared a date to check for the next action

If a final refusal stands, your options are an appeal to the Trademark Trial and Appeal Board (15 U.S.C. § 1070) or, in some cases, a request for reconsideration. For that path, see Responding to Patent Office Actions for analogous strategy in the patent context and, for the trademark-specific landscape, our broader Trademark Registration Guide. The TTAB appeal route mirrors the analysis examiners apply, so a clean prosecution record is your best asset.


Part 6: Publication and Opposition Checklists

When the examining attorney approves a mark, it is published in the Official Gazette, opening a 30-day window in which any party who believes it would be damaged may oppose (15 U.S.C. § 1063) or request an extension of time to oppose. Most applications sail through unopposed. When opposition comes, it is litigation—an inter partes proceeding before the TTAB with discovery, testimony, and briefing.

Checklist 6.1: Pre-Publication

  • Monitored status for the publication date (TSDR)
  • Understood the 30-day opposition window (and that opposers can extend it)
  • Considered whether to proactively contact any party likely to object
  • Identified litigation counsel in case an opposition is filed

Checklist 6.2: If an Opposition Is Filed

Immediate step Done
Calendared the answer deadline (40 days from institution)
Obtained and read the Notice of Opposition
Identified the opposer and its claimed grounds (often § 2(d) priority, or descriptiveness)
Assessed the strength of the claims against your defenses
Engaged trademark litigation counsel
Evaluated settlement and coexistence options
Option When it makes sense
File an answer and defend Strong registrability case; the mark is worth the fight
Negotiate a coexistence agreement Both parties can live with limits on goods, channels, or geography
Amend the application A narrowing amendment resolves the opposer's concern
Abandon Weak position; litigation cost exceeds the mark's value

Opposition practice rewards parties who understand standing and preclusion. The Supreme Court's B&B Hardware, Inc. v. Hargis Industries, Inc., 575 U.S. 138 (2015), held that a TTAB likelihood-of-confusion ruling can have issue-preclusive effect in later federal litigation—so a Board loss is not always a contained loss. And entitlement to oppose now runs through the Lexmark zone-of-interests framework (Lexmark Int'l, Inc. v. Static Control Components, Inc., 572 U.S. 118 (2014); Corcamore, LLC v. SFM, LLC, 978 F.3d 1298 (Fed. Cir. 2020)). For the discovery mechanics of these proceedings, see Discovery Practice in TTAB Trademark Proceedings.


Part 7: Intent-to-Use Endgame Checklists

A Section 1(b) application has an extra act. If it survives examination and publication, the USPTO issues a Notice of Allowance (NOA) rather than a registration—because you still have to prove you actually started using the mark. From the NOA, you have six months to file a Statement of Use (SOU) showing real use in commerce, or to buy more time.

Checklist 7.1: Statement of Use Preparation

Task Deadline Done
Calendared the SOU deadline (6 months from NOA) Day 1
Confirmed actual use in commerce has begun on each item Before filing
Prepared a compliant specimen (run Checklist 3.2) Before filing
Determined real dates of first use Before filing
Deleted any goods/services not yet in use (or kept them under an extension) Before filing
Filed the SOU (or an extension) before the deadline By deadline

The SOU fee is currently $150 per class. A critical discipline: do not file an SOU claiming use on goods you are not actually selling. Doing so leaves the registration vulnerable to a post-registration audit, to a nonuse cancellation, and—now—to TMA reexamination (below). If you are using on some items but not others, delete the unused ones from the SOU (or shift them to an extension request).

Checklist 7.2: Extension Requests

If you need more runway, each extension is $125/class and buys six months, up to a total of 36 months from the NOA.

Extension File by Fee Filed
1st (to month 12) 6 months from NOA $125/class
2nd (to month 18) 12 months $125/class
3rd (to month 24) 18 months $125/class
4th (to month 30) 24 months $125/class
5th (to month 36) 30 months $125/class
  • Each request restates ongoing bona fide intent
  • Second and later requests show good cause—documented, ongoing steps toward use (product development, manufacturing, market research, securing distributors or approvals); a bare assertion of "effort" is not enough (TMEP § 1108)
  • Every extension deadline is calendared the moment the prior filing posts

Hard ceiling: 36 months from the NOA. Miss the final SOU deadline and the application is abandoned (15 U.S.C. § 1051(d)). For the full strategy, see Intent-to-Use Trademark Applications.


Part 8: Post-Registration Maintenance Checklists

Registration is a milestone, not a finish line. A federal registration is a use-it-or-lose-it right, and the USPTO requires periodic proof. Miss a maintenance deadline and the registration is cancelled or expires—and unlike a missed prosecution deadline, there is often no petition to revive. This is where docketing discipline earns its keep, and where Trailhead, years later, is glad it built the calendar on day one.

Checklist 8.1: The Maintenance Deadline Tracker

Filing Window opens Deadline Grace ends Authority
§ 8 Declaration of Continued Use Year 5 Year 6 Year 6 + 6 mo. 15 U.S.C. § 1058

     ...
Year19├──┬── next § 8 & § 9 window opens
Year20│  └── § 8 & § 9 deadline ──► grace period (6 mo., +fee)

Checklist 8.2: Section 8 — Declaration of Continued Use

Due between years 5–6, and with every § 9 renewal thereafter (15 U.S.C. § 1058).

  • Confirmed the mark is still in use in commerce for all listed goods/services
  • Deleted any goods/services no longer in use (do not certify use you cannot prove)
  • Prepared a current specimen and verified it (Checklist 3.2)
  • Filed the § 8 declaration with the specimen and fee ($325/class)
  • Filed before the deadline to avoid the grace-period surcharge (+$100/class)
  • Saved the confirmation

Checklist 8.3: Section 15 — Declaration of Incontestability

Optional, but quietly one of the most valuable filings a brand owner can make. Filed after five consecutive years of post-registration use (usually bundled with the first § 8), incontestability under 15 U.S.C. § 1065 converts your registration from prima facie evidence of validity into conclusive evidence under § 1115(b). The practical payoff, blessed in Park 'N Fly, Inc. v. Dollar Park & Fly, Inc., 469 U.S. 189 (1985): a defendant can no longer attack an incontestable mark as merely descriptive.

Eligibility

  • Five consecutive years of continuous use since registration
  • No final adverse decision on ownership or the right to register
  • No proceeding currently challenging the rights
  • The mark has not become generic

What incontestability does and does NOT shield against:

Challenge Shielded?
Mere descriptiveness
Certain prior-use claims ✓ (with statutory exceptions)
Genericness ✗ (always available—Ginn, Booking.com)
Functionality
Fraud ✗ (Bose)
Abandonment
  • Filed the § 15 declaration (fee $250/class) once eligible—it materially strengthens the rights

Checklist 8.4: Section 9 — Renewal

Due every ten years (years 9–10, 19–20, and so on), filed together with the § 8 declaration (15 U.S.C. § 1059).

  • Confirmed continued use (or documented excusable nonuse)
  • Filed the combined § 8 & § 9 within the proper window
  • Paid the combined fee ($650/class); added the grace-period fee if filing late
  • Saved the confirmation

Checklist 8.5: Ongoing Registration Hygiene

Task Frequency Last done
Monitor for infringing/confusingly similar uses (watch service) Ongoing
Record assignments (with goodwill) when ownership changes As needed
Update the owner's address with the USPTO As needed
Record security interests if the mark is collateral As needed
Review whether the goods/services still match reality Annually
Verify all maintenance deadlines are calendared Annually
Save current specimens of use (audit-ready evidence) Annually
Audit proper trademark usage in marketing (avoid genericide) Annually

Part 9: The TMA's New Hazards—Expungement and Reexamination

The Trademark Modernization Act of 2020 added two ex parte proceedings that every registrant should understand, because they let anyone—or the Director acting alone—challenge a registration for nonuse without the cost of a full TTAB cancellation. They are aimed squarely at the deadwood and fraudulent-specimen registrations that have clogged the register.

  • Expungement (15 U.S.C. § 1066a; 37 C.F.R. § 2.91). Cancels some or all goods/services on the ground that the mark was never used in U.S. commerce for them. Available against any basis—including § 44(e) and § 66(a) registrations that issued without a use requirement—generally when the registration is between 3 and 10 years old.
  • Reexamination (15 U.S.C. § 1066b). Cancels goods/services on the ground that the mark was not in use as of the relevant date when use was required. Available only against § 1(a)/§ 1(b) registrations less than 5 years old; it targets registrations built on improper or fabricated specimens.

Both run $400 per class, require the petitioner to conduct a "reasonable investigation" (37 C.F.R. § 2.91(d)), and proceed ex parte once the Director finds a prima facie case of nonuse—the registrant then rebuts by proving use. The defensive lesson is simple and threads through this entire collection: claim use only on goods and services you can actually prove you sell, and keep the proof. A use audit is no longer a remote possibility; it is a designed feature of the modern system.


Part 10: Special-Situation Checklists

Checklist 10.1: Recording a Trademark Assignment

A trademark cannot be sold like a chair—it must travel with the goodwill of the business it symbolizes. An assignment "in gross" (without goodwill) is invalid and can destroy the rights.

  • Execute a written assignment that expressly conveys the mark and its goodwill
  • Identify the mark, registration/serial number, and the goods/services
  • Have both parties sign
  • Record with the USPTO Assignment Recordation Branch (confirm the current fee at USPTO.gov)
  • Verify the recordation appears in USPTO records
  • Update the maintenance calendar with the new owner's information

Checklist 10.2: Responding to a Cease-and-Desist Letter

Step Done
Note any stated deadline; do not ignore it
Preserve all communications and relevant documents
Avoid admissions or counter-accusations in any initial reply
Research the sender's actual rights (registrations, priority, scope)
Assess the strength of their claim against your defenses
Weigh business impact and settlement options
Engage trademark counsel before substantively responding

For the full playbook, see Responding to a Trademark Cease and Desist Letter and, if you are on the sending side, Drafting a Trademark Cease and Desist Letter.

Checklist 10.3: International Expansion

  • Identified target countries
  • Evaluated the Madrid Protocol route versus direct national filings
  • For Madrid: filed the international application through the USPTO (note § 66(a) U.S.-designation fees)
  • For direct filing: engaged local counsel in each jurisdiction
  • Budgeted for country-specific examination and fees
  • Calendared international deadlines (they differ from U.S. dates)
  • Planned for local use requirements and translation/transliteration

Frequently Asked Questions

How long does federal registration take? Plan on at least a year for a smooth application, and often longer if you draw an office action or face an opposition—both of which add months. Intent-to-use applications run longer still, because the Statement-of-Use phase can stretch up to 36 months from the Notice of Allowance.

Do I have to use the mark before I file? No. A Section 1(b) intent-to-use application lets you file before launch and secure a constructive-use priority date that, on registration, reaches back to your filing date nationwide (15 U.S.C. § 1057(c)). You complete the use showing later via a Statement of Use. See Intent-to-Use Trademark Applications.

What is the single most common reason applications stall? Two things, roughly tied: likelihood-of-confusion refusals under § 2(d) (which a clearance search would have flagged) and specimen problems—especially submitting mere advertising for goods, or an ornamental use that doesn't function as a mark.

My mark is descriptive. Is it hopeless? Not at all—just slower. You can claim acquired distinctiveness under § 2(f) (five years of substantially exclusive use is prima facie evidence, ideally backed by sales and advertising), or register on the Supplemental Register and build secondary meaning over time. Only generic terms are truly unregistrable.

Why bother with a Section 15 incontestability filing? Because it upgrades your registration from prima facie to conclusive evidence of validity (15 U.S.C. § 1115(b)) and forecloses a descriptiveness attack (Park 'N Fly, 469 U.S. 189). It is cheap insurance for a mark you intend to keep.

Can someone cancel my registration for nonuse even after it issues? Yes—more easily than before. Beyond traditional TTAB cancellation, the Trademark Modernization Act created ex parte expungement and reexamination proceedings targeting registrations for goods/services where the mark was never used or was not in use when use was claimed. The defense is to claim use only where it is real and to keep the evidence.

What happens if I miss a maintenance deadline? The registration enters a six-month grace period (with an added fee). Miss the grace period too, and the registration is cancelled or expires—generally with no revival. You would have to start over and would lose your priority date.

How is this checklist different from the "From Filing to Registration" one? This article is the deeper, doctrine-and-authority version that starts at strategy and clearance and explains the law behind each step. The sibling, USPTO Trademark Application Checklists: From Filing to Registration, is the leaner filing-desk companion. Use this one to understand and decide; use that one as a fast operational tick-list.


Conclusion: Make the Method a Habit

Trademarks are often the most valuable assets a business owns, and—unlike most assets—they live or die on procedure. The doctrine is interesting; the deadlines are merciless. The discipline these checklists encode is what stands between a clean registration and the regret that opened this article.

Build them into your workflow. Start every new brand with the distinctiveness gate and a clearance search (Part 1). Work through identification, specimens, basis, and filing systematically (Parts 2–4). When the office action comes—and it usually does—triage and answer every point (Part 5). Watch publication, complete the intent-to-use endgame, and the moment a registration issues, set up maintenance tracking (Parts 6–8). Then guard against the TMA's new nonuse attacks by claiming only what you can prove (Part 9). As Trailhead Outdoor Co. would tell you, the payoff for method shows up precisely when something is at stake—a looming Section 8 deadline, a surprise refusal, an opposer's letter.
