How Trademark Registration Works: From Clearance Search to Registration Certificate

The USPTO received 612,084 trademark applications in FY2024. Roughly 30% of them will never reach trademark registration. Some get refused for likelihood of confusion with existing marks. Others die because the applicant missed a deadline, filed a defective specimen, or chose a mark that was descriptive from the start.

The difference between the applications that succeed and the ones that fail is, overwhelmingly, whether the applicant understood the trademark registration process before they started it. If you are trying to figure out how to register a trademark, this guide covers every stage of that process, with the specific numbers, deadlines, and decision points that determine outcomes. For a quick reference version, see the Trademark Registration Process overview.

What Trademark Registration Actually Gives You

A trademark exists the moment you use a distinctive name, logo, or slogan in commerce. That is common law trademark rights. Those rights are real, but limited.

Common law rights extend only to the geographic area where you actually conduct business. If you sell under the name ATLAS in Portland, Oregon, someone else can start using ATLAS in Tampa, Florida, and you have no claim against them.

Federal trademark registration, governed by the Lanham Act (the primary US trademark statute, enacted in 1946 and amended many times since), changes that calculus in several concrete ways.

Nationwide priority. Registration gives you constructive notice of your claim across the entire United States, regardless of where you actually operate. That person in Tampa? They are now on notice of your rights.

Legal presumptions. Registration creates a legal presumption of your ownership of the mark and your exclusive right to use it in connection with the goods and services listed in the registration. In litigation, this shifts the burden. Your opponent has to prove you do not own the mark, rather than you proving that you do.

Federal court access. Registration opens the door to federal courts, offering procedural advantages and the possibility of enhanced remedies including treble damages and attorneys' fees in cases of willful infringement.

Customs recordation. A federal registration can be recorded with US Customs and Border Protection to block importation of infringing goods.

International filing basis. A US registration (or pending application) can serve as the basis for filing in other countries through the Madrid Protocol, the international system that lets you extend protection to multiple jurisdictions through a single application.

When is registration worth the cost? For most businesses where the brand name carries meaningful value, registration typically justifies the expense. The cost is measured in hundreds of dollars. The cost of rebranding after a cease-and-desist letter is measured in tens of thousands, or more.

The calculus becomes more nuanced for purely local businesses, personal projects, or marks that may change soon, but even startups at the earliest stages often benefit from filing an intent-to-use application to lock in a priority date.

Before You File: The Clearance Search

Approximately 20-25% of trademark applications receive a Section 2(d) refusal, which means the examining attorney found a likelihood of confusion with an existing mark. That is the single most common substantive ground for refusal, and in most cases it is preventable with a proper clearance search before filing.

A clearance search is not the same as typing your proposed mark into a search engine and seeing what comes up. A competent clearance search covers multiple layers. For a full treatment of why this step matters, see Why Search Trademarks.

Federal registered and pending marks. The USPTO's database of active registrations and pending applications is the starting point. You are searching not just for identical marks, but for marks that are phonetically similar, visually similar, or conceptually similar in related goods or services. "KLEAR" and "CLEAR" in the same class will trigger a refusal. So might "CLEARVIEW" and "CLEARVUE."

State registrations. All 50 states maintain their own trademark registers. A mark that is not federally registered may still have state registration, which creates enforceable rights.

Common law marks. Unregistered marks that are in actual use can form the basis of an opposition or a likelihood of confusion refusal. These are harder to find because they exist in business directories, domain registrations, social media, and the broader commercial record.

The legal standard the USPTO applies is likelihood of confusion, a multifactor test that evaluates the similarity of the marks, the relatedness of the goods and services, the channels of trade, the conditions of purchase, and other factors. The test is not "are these marks identical?" It is "would a reasonably prudent consumer be likely to be confused about the source of the goods?"

Skipping the clearance search to save a few hundred dollars is a false economy. If your application gets refused on 2(d) grounds, you have lost the filing fee (non-refundable), the 3-4 months you waited for examination, and potentially the window to file under a different mark. If you have already launched the brand, you face a rebrand.

The stronger approach: conduct a clearance search, evaluate the results with a trademark attorney if the field is crowded, and file with confidence. For a detailed walkthrough of search techniques, see How to Search Trademarks.

Choosing Your Filing Basis

Every USPTO trademark application must declare a filing basis, and the choice has significant implications for timing, cost, and procedural requirements. The two domestic bases account for the vast majority of filings.

Section 1(a): Use in Commerce

If you are already using the mark in commerce at the time of filing, you file under Section 1(a). "Use in commerce" means the mark is being used on goods that are sold or transported in interstate commerce, or in connection with services rendered in interstate commerce. This is not aspirational. The mark must be in actual use.

A Section 1(a) application requires a specimen showing the mark as actually used in commerce. For goods, this is typically a photograph of the product packaging, a label, or a tag. For services, it is typically a screenshot of a website, an advertisement, or marketing material that shows the mark in connection with the services.

The advantage of a use-based application is straightforward: if the mark passes examination and survives the opposition period, it proceeds directly to registration. No additional filings are required.

Section 1(b): Intent to Use

If you have a bona fide intention to use the mark but have not started yet, you file under Section 1(b). Intent-to-use (ITU) applications now account for roughly 40% of total filings at the USPTO, reflecting the reality that many businesses need to secure their mark before launch.

An ITU application does not require a specimen at filing. However, after the application is approved and published, you will receive a Notice of Allowance and must then file a Statement of Use (with a specimen) within six months. You can request extensions of time to file the Statement of Use, up to a maximum of three years from the Notice of Allowance, but each six-month extension costs $125 per class.

The ITU path adds time and money to the process, but it lets you establish a priority date (the date of filing) months or years before you actually launch.

Foreign-Based Filings

Section 44(d) allows applicants to claim priority based on a foreign application filed within the previous six months. Section 44(e) allows registration based on a foreign registration. Section 66(a) covers applications filed through the Madrid Protocol. These bases are most relevant for international brands entering the US market.

For most US-based applicants, the choice is between 1(a) and 1(b). The decision point is simple: are you already using the mark in commerce, or not?

For a full breakdown of application preparation, see Preparing a Trademark Application.

The Trademark Application: What You File and What It Costs

The USPTO offers two electronic filing options, and the one you choose affects both cost and flexibility.

TEAS Plus vs. TEAS Standard

TEAS Plus costs $250 per class and requires you to select your goods and services descriptions from the USPTO's Trademark ID Manual, a pre-approved list of descriptions. You must also agree to receive all correspondence electronically and meet several other requirements. If you fail to meet any TEAS Plus requirement during prosecution, the application is converted to TEAS Standard and you pay the additional $100 per class.

TEAS Standard costs $350 per class and allows you to write your own goods and services descriptions. This flexibility is valuable when your product or service does not fit neatly into the ID Manual's pre-approved language, but it can also invite office actions if your description is too broad, too vague, or uses non-standard terminology.

For most straightforward applications (standard software products, common retail goods, established service categories), TEAS Plus is the better option. The savings add up in multi-class applications, and the discipline of using pre-approved descriptions often produces cleaner applications. Custom descriptions become necessary when you operate in a niche that the ID Manual has not caught up to.

Nice Classes

Every trademark application must specify one or more Nice classes, the international classification system that organizes goods and services into 45 categories (34 for goods, 11 for services). Each class requires its own filing fee, its own goods/services description, and its own specimen.

Choosing the right class is not always obvious. Software, for example, can fall under Class 9 (downloadable software), Class 42 (software as a service), or both. A coffee shop might need Class 30 (coffee as a product) and Class 43 (restaurant and cafe services). Filing in too few classes leaves gaps in protection.

Filing in too many classes increases costs and requires specimens for each, which can be problematic if you do not actually offer goods or services in every class you claim.

For a detailed treatment of the classification system, see the Nice Classification 2026 Guide and the Trademark Classes reference.

Specimen Requirements

A specimen proves your mark is actually being used in commerce in connection with the claimed goods or services (required at filing for 1(a) applications, and at the Statement of Use stage for 1(b) applications).

For goods (Classes 1-34), acceptable specimens include product packaging, labels, tags, or displays associated with the goods at the point of sale. A website showing the product for sale with the mark and an "add to cart" button generally qualifies. An advertisement alone, without a direct purchasing mechanism, typically does not.

For services (Classes 35-45), acceptable specimens include advertising, marketing materials, or website pages that show the mark in direct association with the services. A business card, letterhead, or invoice that merely shows the mark as a source identifier is also generally acceptable.

The specimen is a surprisingly common failure point. The USPTO rejects specimens that show the mark used ornamentally (a large decorative design on a t-shirt, for instance, is not a trademark use), informational use (merely describing a feature), or use that does not connect the mark to the specific goods or services claimed.

Trademark Registration Cost: The Full Picture

A single-class TEAS Plus application costs $250 in USPTO fees. A three-class TEAS Plus application costs $750. But the filing fee is only one component. A realistic trademark registration cost budget includes:

• Clearance search: $500-$2,000 for a comprehensive search through a professional search firm, or less if conducted through online search tools
• Attorney fees: $1,000-$3,000 for an attorney to conduct the search, prepare the application, and manage prosecution through registration
• Filing fees: $250-$350 per class
• Statement of Use (ITU only): $100 per class
• Extensions of time (ITU only): $125 per class per six-month extension
• Maintenance filings: Ongoing (see the maintenance section below)

The total cost for a straightforward single-class registration with attorney assistance typically falls in the $2,000-$4,000 range. Complex applications (multiple classes, crowded fields, office actions) can run significantly higher. Self-filing reduces the cost but increases the risk of procedural errors, particularly for applicants unfamiliar with the process.

Trademark Registration Examination: What Happens After You File

After you submit your application, it enters a queue. The USPTO assigns it to an examining attorney, typically within 3-4 months of filing. The examining attorney is a licensed attorney employed by the USPTO whose job is to review the application for compliance with all statutory requirements.

What the Examiner Checks

The examining attorney reviews the application for both procedural and substantive issues:

• Likelihood of confusion with existing marks (Section 2(d)), the most common substantive refusal
• Descriptiveness (Section 2(e)(1)), where the mark merely describes a feature, quality, or characteristic of the goods
• Deceptive or misleading matter (Section 2(a))
• Proper classification of goods and services
• Adequacy of the specimen (for use-based applications)
• Compliance with formalities (proper drawing of the mark, acceptable identification, correct filing basis declaration)

If the examining attorney finds no issues, the application is approved for publication. If there are issues, the examiner issues an office action.

Office Actions

An office action is a letter from the examining attorney identifying the problems with the application and requesting a response. Office actions can be substantive (likelihood of confusion, descriptiveness) or procedural (deficient specimen, unclear description of goods).

You have three months from the date of the office action to respond. This deadline can be extended by three additional months for a fee of $125 per class, but the initial three-month window is firm. Missing it results in abandonment of the application.

Responding to office actions is where attorney involvement is most valuable. A 2(d) refusal based on likelihood of confusion, for example, can sometimes be overcome by arguing that the goods and services are sufficiently distinct, that the marks create different commercial impressions, or that the cited mark is weak. These arguments require legal analysis and familiarity with TTAB and Federal Circuit precedent. A well-crafted response can save an application. A poorly argued one wastes the response opportunity.

For common office action types and response strategies, see Responding to Office Actions.

You can track the status of your application through the USPTO's Trademark Status and Document Retrieval (TSDR) system. Note that the old Trademark Electronic Search System (TESS) was retired in late 2023 and replaced by a new search interface. For a full overview of current trademark search and monitoring tools, see TESS Is Gone: How to Search Trademarks in 2026.

Publication and Opposition

Once the examining attorney approves the application (either on initial review or after a successful office action response), the mark is published in the Official Gazette, the USPTO's weekly publication that announces marks approved for registration.

The 30-Day Opposition Window

Publication opens a 30-day window during which any party who believes they would be damaged by the registration can file an opposition. This is the trademark system's mechanism for allowing the private sector to police the register. The USPTO examiner may not have caught every conflicting mark, and existing brand owners are given the opportunity to raise objections.

In practice, approximately 3% of published marks face an opposition. The rate varies by class (fashion and food categories see higher opposition rates than, say, industrial chemicals) and by the notoriety of the mark (applications in crowded fields with well-known brands are more likely to draw attention).

A potential opposer can request a 90-day extension of time to oppose before filing a formal opposition, which is common and essentially cost-free. This extension period is where most disputes are resolved through negotiation rather than formal proceedings.

If Someone Opposes

A formal opposition is a proceeding before the Trademark Trial and Appeal Board (TTAB), the administrative tribunal within the USPTO that adjudicates inter partes disputes. TTAB proceedings resemble litigation in structure (pleadings, discovery, trial briefs) but are conducted on the written record, without live testimony in most cases.

Opposition proceedings typically last 12-18 months, though they can extend longer. The most common ground is likelihood of confusion (the same standard the examining attorney applies, but now argued by a private party with skin in the game). The opposer bears the burden of proving their case.

Many oppositions settle before reaching a decision, often through consent agreements where the parties agree to coexist under specific conditions (different geographic markets, different product lines, different trade channels). For a deeper analysis of opposition and cancellation proceedings, see Trademark Opposition and Cancellation.

Registration and the First Five Years

If no opposition is filed (or any opposition is resolved in the applicant's favor), the next step depends on your filing basis.

For Use-Based Applications (Section 1(a))

The USPTO issues a registration certificate. Your mark is now a registered trademark. You can begin using the (R) symbol (prior to registration, only the TM symbol is appropriate for unregistered marks).

For Intent-to-Use Applications (Section 1(b))

Instead of a registration certificate, you receive a Notice of Allowance (NOA). The NOA gives you six months to file a Statement of Use (SOU), which is essentially your proof that you have begun using the mark in commerce, accompanied by a specimen. You can request up to five additional six-month extensions (for a total of three years from the NOA date), at $125 per class per extension.

Only after the SOU is filed and accepted does the USPTO issue the registration certificate. This is the step where many ITU applications die: the applicant secures the allowance but never actually launches the product, or launches but fails to file the SOU.

Maintenance: The Obligations Do Not End at Registration

A trademark registration is not permanent. It requires active maintenance.

Between the 5th and 6th year after registration, you must file a Section 8 Declaration of Continued Use (or Excusable Nonuse). This filing requires proof that the mark is still in use in commerce. Miss this window and the registration is cancelled. No exceptions, no extensions.

Many practitioners file a combined Section 8 and Section 15 declaration at this point. The Section 15 declaration claims "incontestable" status for the mark, which significantly strengthens the registration by making it immune to certain challenges (including that the mark is merely descriptive). Incontestability is one of the most valuable benefits of federal registration, and it is available only after five continuous years of use.

Every 10 years after registration, you must file a combined Section 8 (continued use) and Section 9 (renewal) declaration. The renewal keeps the registration alive for another 10-year term.

Roughly 70% of filed applications ultimately achieve registration. But an unknown additional percentage lapse post-registration because the owner fails to maintain the filing. Calendaring those deadlines is essential. For a full guide to the maintenance schedule, see Trademark Renewal and Maintenance.

Trademark Registration Timeline and Cost

Trademark registration timelines vary significantly depending on whether the application encounters any obstacles. Three realistic scenarios:

Best Case: 12-13 Months

You file a use-based (1(a)) application with a strong mark in an uncrowded field. The examining attorney finds no issues and approves the application on first review. The mark publishes in the Official Gazette, no opposition is filed, and the registration certificate issues.

• Filing to first examination: 3-4 months
• Examination to publication: 1-2 months
• Publication and opposition period: 30 days
• Publication to registration: 2-3 months
• Total: approximately 12-13 months
• Cost: $1,500-$3,000 (search, filing, basic attorney fees)

Typical Case: 14-18 Months

A non-final office action is issued (perhaps the examiner requires a revised goods/services description, or questions the specimen). You respond within three months, the examiner accepts the response, and the application proceeds to publication. No opposition.

• Filing to first examination: 3-4 months
• Office action response period: 1-3 months
• Revised examination: 1-2 months
• Publication and opposition: 30 days
• Registration: 2-3 months
• Total: approximately 14-18 months
• Cost: $2,500-$5,000 (adds attorney time for office action response)

Contested Case: 24+ Months

The application draws a substantive 2(d) refusal. You respond with arguments and evidence. The examiner issues a final refusal. You appeal to the TTAB or request reconsideration. Alternatively, the mark publishes but a third party files an opposition.

• Filing through contested examination: 8-14 months
• TTAB appeal or opposition proceeding: 12-18 months
• Total: 24 months or more
• Cost: $5,000-$25,000+ (TTAB proceedings require significant attorney involvement)

These timelines are US-specific. International trademark registration through the Madrid Protocol or direct filing in other jurisdictions follows different procedures with different timelines.

Mistakes That Kill Trademark Registration Applications

These are the errors that kill applications or create expensive problems.

No Clearance Search

Filing without searching is a gamble with poor odds. With 20-25% of applications receiving 2(d) refusals, the base rate of encountering a conflicting mark is substantial. A $500 clearance search is cheap insurance against a lost $250-$350 filing fee, months of wasted time, and a potential rebrand.

Choosing a Descriptive Mark

A mark that merely describes the goods or services ("FAST DELIVERY" for a shipping service, "COLD BREW" for coffee) will face a Section 2(e)(1) descriptiveness refusal. The stronger your mark is on the distinctiveness spectrum (fanciful or arbitrary marks are strongest), the smoother the registration process. "APPLE" for computers is arbitrary and strong. "COMPUTER STORE" for a computer store is descriptive and unregistrable.

For guidance on selecting a registrable name, see How to Name a Brand. For a detailed treatment of the distinctiveness spectrum, see Trademark Strength and Distinctiveness.

Wrong or Overbroad Goods/Services Description

The goods and services description defines the scope of your registration. Too narrow and you lack protection where you need it. Too broad and the examining attorney will require amendments, or worse, your description will overlap with existing marks and trigger a 2(d) refusal that a narrower description would have avoided.

Use the USPTO's Trademark ID Manual as a starting point. The pre-approved descriptions are accepted without question for TEAS Plus applications and provide a reliable template for TEAS Standard filings.

Inadequate Specimens

The specimen must show the mark used as a trademark in commerce. Common failures: submitting a mockup or prototype instead of an actual product in the marketplace, submitting a website that shows the mark but has no purchasing functionality, or submitting a specimen that shows the mark used ornamentally rather than as a source identifier.

Missing Deadlines

The USPTO's deadlines are unforgiving. Three months to respond to an office action (extendable to six). Six months to file a Statement of Use after a Notice of Allowance (extendable to three years total). The Section 8 declaration between years five and six. Miss any of these, and the application or registration is lost.

The single most preventable cause of application failure is not a legal issue. It is a calendaring issue. The most reliable prevention is a calendaring system with reminders set months in advance of each deadline.

What Comes Next

This guide covers the US federal trademark registration process. International registration, whether through the Madrid Protocol or direct filing in national offices, follows different procedures with different timelines and requirements. If you are considering protection beyond the United States, see International Trademark Filing for a detailed treatment.

Regardless of jurisdiction, the process starts in the same place: confirming that your mark is available. A thorough clearance search before filing is the single highest-value step in the entire registration process. Signa provides free trademark search tools at signa.so to help check availability across 200+ jurisdictions.

Consult a trademark attorney for legal guidance specific to your situation, particularly if your clearance search reveals potential conflicts or if your mark operates in a crowded field.
