How to Register a Trademark in the United States and Canada

How to Register a Trademark in the United States and Canada

Trademarks are legally protected names, logos, symbols, and other identifiers that distinguish the goods or services of one business from those of others. They serve as the foundation of brand identity and goodwill in commerce. When a trademark is registered with the government, the owner gains significant legal advantages: a registration creates a presumption of the registrant’s ownership and exclusive rights, and it provides nationwide priority as of the filing date, among other benefits. In practical terms, obtaining a trademark registration formalizes enforceable rights in a brand.

A trademark allows the owner to exclude others from using confusingly similar marks for related goods or services, while trademark rights in the United States and Canada can arise through use alone (common law rights). Registration underpins a stronger, statutory set of rights that are easier to enforce and harder to challenge. This article will explain the procedures for registering trademarks, the standards applied by each country’s trademark office during examination, and the key documents and deadlines involved at each stage of the process.

Legal Definition and Scope of Trademark Rights

This analysis compares the legal frameworks for trademark protection in the United States and Canada. While both systems aim to protect brand identity and prevent consumer confusion, they are governed by distinct statutes

US and Canadian Statutory Trademark Definitions

Both jurisdictions define trademarks as source identifiers, though their legislative foundations reflect different constitutional origins.

• Lanham Act Framework in the United States

Under 15 U.S.C. § 1127, a trademark includes any word, name, symbol, or device used in commerce to identify goods or services. Because U.S. law is rooted in the Commerce Clause, federal registration generally requires the mark to be used in interstate or foreign commerce.

• Trademarks Act Framework in Canada

Canada defines a trademark as a “sign” or combination of signs used to distinguish products or services (Trademarks Act, s. 2). The Canadian definition of a “sign” is broad and explicitly includes modern formats like holograms and moving images. Notably, Canada does not require “use” at the time of filing.

• Distinctiveness as a Shared Trademark Principle

A fundamental requirement in both nations is that a mark must be distinctive. It must be capable of identifying a single source rather than simply describing the product. Generic terms cannot be registered in either country.

Registrable Trademark Types and Categories

The scope of what can be registered has expanded significantly beyond traditional brand names and logos.

Traditional Word and Design Mark Protection

Both the USPTO and CIPO accept standard character marks (letters and slogans) and design marks (stylized logos). Standard character marks provide the broadest protection as they cover the wording regardless of its visual presentation.

Sensory and Nontraditional Trademark Examples

Modern law recognizes that consumers identify brands through more than just sight:

• Color: Registrable if it has acquired “secondary meaning” (e.g., Qualitex Co. green-gold).
• Sound: Recognizable audio identifiers, such as the NBC chimes or the MGM lion’s roar.
• Scent and Texture: While difficult to register, these are permitted if they are non-functional and serve as source indicators.

Prohibited and Excluded Trademark Subject Matter

Neither country allows the registration of:

• Official Symbols: Government flags, coats of arms, or insignias.
• Personal Identities: Names or likenesses of individuals without their consent.
• Functional Features: Product shapes or features essential to the item’s use (e.g., the circular shape of a specialized drill bit).
• Generic Terms: The common names for the goods themselves.

Legal Rights Conferred by Trademark Registration

Registration provides a powerful set of legal tools that common-law rights alone do not offer.

• Presumptions of Validity and Trademark Ownership

In the U.S., registration on the Principal Register is prima facie evidence of ownership. After five years of continuous use, a mark can become incontestable. In Canada, registration grants the owner the exclusive right to use the mark nationwide for the listed goods and services.

• Nationwide Priority and Constructive Use Rights

A federal filing in the U.S. establishes “constructive use” priority as of the filing date, granting nationwide rights even before the business expands geographically. Similarly, Canadian registration provides protection across all provinces regardless of where the actual business is physically located.

• Trademark Enforcement and Legal Remedies

Registered owners have access to robust enforcement mechanisms:

• Injunctions and Damages: Both countries allow owners to stop infringing use and seek monetary compensation.
• Customs Enforcement: Owners can record their marks with border services (U.S. Customs) to block the importation of counterfeit goods.
• Depreciation of Goodwill: Canadian law (s. 22) provides a unique remedy for the “dilution” of a brand’s value, even if there is no direct consumer confusion.

• Trademark Renewal Terms and Maintenance

In both the U.S. and Canada, trademarks have a 10-year term and can be renewed indefinitely. However, the U.S. requires a mandatory Declaration of Use between the 5th and 6th year to maintain the registration.

How U.S. Trademark Registration, Requirements, and Filing Works

Before you can register a trademark in the United States, you must understand the legal foundation behind the system, the eligibility criteria, and the different application types available. This section outlines the key U.S. trademark laws, the role of the USPTO, and the step-by-step requirements for filing, including what makes a mark registrable and what can lead to refusal.

U.S. Trademark Law: The Lanham Act and USPTO Authority

The Lanham Act governs U.S. trademark rights, codified at 15 U.S.C. §§ 1051–1127. The relevant provisions include:

• §§ 1–2: Filing requirements and refusal grounds (e.g., confusion, descriptiveness)
• § 7: Legal effect of registration
• §§ 13–14: Opposition and cancellation before the TTAB
• § 45: Definitions, including “use in commerce”

The United States Patent and Trademark Office (USPTO) is the federal agency responsible for trademark examination and registration. USPTO operations are regulated under 37 C.F.R. Part 2, and interpreted through the Trademark Manual of Examining Procedure (TMEP).

The Trademark Trial and Appeal Board (TTAB) handles disputes (e.g., oppositions and cancellations). TTAB rulings can be appealed in federal court or to the U.S. Court of Appeals for the Federal Circuit.

U.S. Trademark Filing Options: Use, Intent, Foreign Registration, and Madrid Protocol

To file for federal trademark protection, you must select a valid statutory basis under the Lanham Act:

1. Section 1(a): Use in Commerce Application

For marks already in use in interstate commerce:

• Provide first use dates and a specimen of use
• Use must be lawful (e.g., marks for illegal cannabis goods are barred)

2. Section 1(b): Intent-to-Use Application

For marks not yet used:

• Requires a bona fide intent to use
• Registration is withheld until proof of use via Statement of Use or Amendment to Allege Use

3. Section 44: Foreign Registration/Application Basis

For nationals of Paris Convention/WTO countries:

• § 44(d): Claim U.S. priority based on a foreign application (within 6 months)
• § 44(e): File based on a valid foreign registration (no U.S. use required at filing)

4. Section 66(a): Madrid Protocol Extension

For applicants with WIPO International Registrations:

• Extends protection to the U.S.
• Does not require proof of U.S. use until maintenance filings

All applications must include a verified declaration under penalty of perjury (37 C.F.R. § 2.33), attesting to the applicant’s rights and accuracy of the information.

What Makes a Trademark Eligible for Registration in the U.S

A trademark must be distinctive and free from statutory bars. The USPTO will reject marks under Lanham Act § 2 for the following reasons:

Likelihood of Confusion – § 2(d)

Most common refusal ground. The USPTO applies the DuPont factors to assess whether the applied-for mark is too similar to existing registered marks in sight, sound, or meaning.

Descriptive or Generic Terms – § 2(e)(1)

• Descriptive marks (e.g., “Cold and Creamy” for ice cream) require proof of secondary meaning to qualify.
• Generic terms (e.g., “Apple Pie” for pies) are never registrable.

Geographic and Surname Refusals – § 2(e)(2–4)

• Primarily geographic terms, surnames, or geographically deceptive terms face refusal unless distinctiveness is proven.
• Names/portraits/signatures of living individuals require consent (§ 2(c)).

Deceptive or False Associations – § 2(a)

• Absolute bar for marks that mislead or falsely suggest a connection to another person, institution, or product.

Other Bars

• Government insignia (§ 2(b)) and scandalous/deceptive matter (still partially enforceable post-Tam and Brunetti) are not registrable.

Procedural Requirements: Submitting a Compliant U.S. Trademark Application

In addition to legal eligibility, every application must meet the following procedural standards:

• Use definite identifications for goods/services (37 C.F.R. § 2.32), ideally from the USPTO’s ID Manual.
• Classify items correctly under the Nice Classification System.
• Submit required drawings, fees (per class), and owner identification.
• Ensure foreign applicants have U.S.-licensed legal representation (mandatory since August 2019)

Use of the ® symbol is restricted to registered marks (15 U.S.C. § 1111); use ™ or ℠ before registration.

U.S. Trademark Registration Step-by-Step Process

Registering a trademark with the United States Patent and Trademark Office (USPTO) is a structured process that involves clearance, formal application, examination, and publication. Understanding each phase—and its legal and procedural requirements—is critical for applicants to secure and preserve trademark rights. This guide breaks down each step, from risk assessment to issuance of a registration certificate, with references to governing standards and timelines.

1. Trademark Clearance and Risk Assessment

Before filing, applicants should search the USPTO TESS database for conflicting marks and assess potential refusals under Lanham Act § 2(d). Clearance reduces the risk of refusal, legal conflict, and lost filing fees. The key standard is the DuPont likelihood of confusion test, which focuses on the similarity of marks and the relatedness of goods/services.

Applicants should:

• Search for similar marks by sound, appearance, and meaning.
• Consider related goods and services.
• Review common-law uses (not in the USPTO database).
• Assess descriptiveness or genericness issues under § 2(e)(1).

Well-documented searches support good-faith adoption and reduce future challenges.

2. Identification of Goods and Services

Applicants must describe goods/services clearly and classify them under the Nice system (Classes 1–45). Descriptions must be definite, using USPTO’s ID Manual terms where possible.

Key points:

• Each class requires a separate fee.
• Descriptions must be specific (e.g., “downloadable software for budgeting” vs. “software”).
• Overbroad or vague terms trigger Office Actions.
• Cannot expand coverage after filing; include all foreseeable uses.

Poor identification can delay or limit protection.

3. Filing the Trademark Application

The USPTO offers two main options:

• TEAS Plus ($250/class): Requires pre-approved ID, Manual terms, and all info upfront.
• TEAS Standard ($350/class): Allows custom descriptions but costs more.

Applications must include:

• Owner’s legal name, entity type, and address.
• Drawing of the mark (word or image).
• Filing basis (e.g., 1(a), 1(b), 44, or 66).
• Specimens (if use-based).
• Signed verification of accuracy and bona fide use or intent.

Applications receive a filing receipt and serial number shortly after submission.

4. Examination by USPTO

Around 6 months post-filing, a USPTO examining attorney reviews the application for:

• Conflicts (§ 2(d)): Confusingly similar marks.
• Descriptiveness (§ 2(e)(1)): Generic or merely descriptive terms.
• Formalities: Required translations, accurate classifications, specimen validity.

Issues are raised via Office Actions, which applicants must answer within 3 months (or request a 3-month extension). Failure to respond leads to abandonment.

5. Publication and Opposition

If no refusals remain, the mark is published in the Official Gazette. Third parties have 30 days to oppose or request an extension (up to 180 days max).

• No opposition: The mark proceeds to registration (if use-based) or receives a Notice of Allowance (if intent-to-use).
• Opposition filed: A TTAB proceeding begins, similar to litigation (answer, discovery, briefing, decision). Most oppositions settle.

6. Registration or Notice of Allowance

• Use-based (1a), foreign (44e), or Madrid (66a) filings: Receive a registration certificate after publication.
• Intent-to-Use (1b) filings: Receive a Notice of Allowance (NOA).

For NOAs, applicants must file a Statement of Use (SOU) within 6 months or request extensions (up to 5 total). SOUs require:

• Date of first use in commerce.
• Specimen per class.
• Signed declaration.

Once accepted, the mark registers.

Key Timelines:

• Initial examination: ~6 months.
• Response to Office Actions: 3 months + optional extension.
• Publication to registration: ~3–4 months.
• ITU: Up to 36 months post-NOA to file SOU.

Trademark Registration in Canada: Legal Framework and Eligibility

Registering a trademark in Canada grants nationwide exclusive rights and access to enforcement mechanisms under the Trademarks Act. Since 2019, significant reforms have aligned Canadian practice with international standards by removing the use requirement at filing, adopting the Nice Classification system, and joining the Madrid Protocol. This section outlines the legal authorities, distinctiveness criteria, and procedural standards that determine trademark eligibility.

Legal Authority and Framework

Trademark registration in Canada is governed by the Trademarks Act (R.S.C. 1985, c. T-13) and associated Trademarks Regulations. Key statutory provisions include:

• Section 2 – Definitions (e.g., “trademark,” “distinctive”);
• Sections 12–14 – Registrability and grounds for refusal;
• Section 16 – Entitlement;
• Sections 30–38 – Application and opposition procedures;
• Section 40 – Registration;
• Section 45 – Non-use cancellation;
• Sections 48–50 – Assignment and licensing.

The Canadian Intellectual Property Office (CIPO) administers trademark applications and maintains the register. The Trademarks Opposition Board (TMOB) handles oppositions and summary cancellation (Section 45). CIPO publishes the Trademarks Examination Manual and Practice Notices, which, though non-binding, guide examiner practices.

Post-2019 amendments modernized Canada’s system: use is no longer required to register, the Nice Classification system was adopted, and Canada joined the Madrid Protocol. Registration now confers nationwide rights, regardless of province, and the Federal Court hears appeals of examiner or opposition decisions.

Eligibility and Filing Standards

Under Section 2, a trademark must be “distinctive” – actually distinguishing the goods/services of the applicant. Since 2019, CIPO examiners may object if a mark is not inherently distinctive, even if it is not clearly descriptive. Evidence of acquired distinctiveness (Section 12(3)) may be used to overcome objections.

Eligible signs include word marks, logos, and non-traditional marks (color, shape, sound, etc.). However, functionality and non-distinctiveness remain bars to registration. Section 12(1) prohibits:

• Surnames (s. 12(1)(a));
• Clearly descriptive or deceptively misdescriptive terms (s. 12(1)(b));
• Generic names (s. 12(1)(c));
• Confusing marks (s. 12(1)(d));
• Scandalous/immoral marks (s. 12(1)(e)).

Section 9 restricts marks that resemble official symbols or institutional names. CIPO will raise objections if such marks are detected.

Filing Requirements and Classifications

• Use Not Required: Since June 2019, no declaration or intent to use is needed at filing or registration.
• Applicant Requirements: Must provide a Canadian address for service (foreign applicants must appoint an address in Canada).
• Goods/Services: Must be listed using Nice Classes, with fees per class. Vague terms (e.g., “software”) are typically refused unless clarified.
• Mark Representation: Word marks are entered as text; design or non-traditional marks (e.g., sound, motion) require specific formats (e.g., sound file, video, images).
• Fees: As of 2025, CAD $478.15 for the first class, CAD $145.12 per additional class.
• Language: Applications must be filed in either English or French. Descriptiveness is assessed in both official languages.

• Priority: Section 16 grants entitlement based on use, filing, or making known in Canada.
• Bad Faith: A registrable ground for opposition (s. 38(2)(a.1)) or cancellation post-registration (s. 18(1)). Defensive filings without intent to use can be challenged.

Canada’s trademark regime now mirrors international norms: no pre-registration use requirement, class-based filing and renewal, broader mark types, and a first-to-file system with post-registration use enforcement.

Comparative Analysis of U.S. and Canadian Trademark Registration Systems

U.S. and Canadian trademark systems share global treaty alignment but diverge in procedural rigor, use requirements, and enforcement tools. U.S. emphasizes use-based rights, stricter formality, and front-loaded obligations, while Canada allows earlier registration with post-grant scrutiny. Strategic filing must account for these differences.

Forms and Documentation for Trademark Registration

A series of specific legal forms and evidentiary requirements govern the trademark lifecycle. Navigating these documents accurately is critical to securing and preserving brand protection in the United States and Canada. The following guide outlines the primary filings, common pitfalls, and the supporting documentation necessary to maintain a healthy trademark portfolio.

United States Trademark Application and Forms

The United States Patent and Trademark Office (USPTO) utilizes the Trademark Electronic Application System (TEAS) for nearly all filings. These forms are strictly interpreted, and errors can lead to the loss of filing dates or total abandonment.

TEAS Plus Application Requirements

This is the most common filing method due to its lower cost (currently $250 per class). It requires the applicant to select goods and services directly from the USPTO ID Manual and agree to electronic communication.

• Common Pitfalls: Using custom descriptions instead of pre-approved terms or failing to include a required translation of foreign words.

TEAS Standard Application Flexibility

This form allows for custom descriptions of goods and services. It is used when a product is highly specialized or does not fit neatly into the ID Manual’s categories.

• Common Pitfalls: Vague descriptions (e.g., “software” without specifying its function) that result in a refusal via an Office Action.

Statement of Use for Intent to Use Applications

For marks filed under a “1(b)” basis (not yet in use), a Statement of Use (SOU) is required once the mark is active in commerce.

• Trigger: Must be filed within 6 months of the Notice of Allowance.
• Specimen Requirement: You must provide proof of use, such as a photo of the product label or a website screenshot where the item can be purchased.

Extension Requests for Statement of Use Filings

If a business is not ready to use it within 6 months, it can file for an extension. Up to five extensions (36 months total) are permitted.

• Common Pitfalls: Missing the deadline by even a single day results in the application being declared abandoned.

Section 8 Declaration of Continued Use

This mandatory filing occurs between the 5th and 6th year of registration. It proves the mark is still being used in interstate commerce.

• Critical Risk: Failing to remove goods or services no longer being sold. Claiming use on items you no longer offer can be considered fraudulent.

Section 15 Declaration of Incontestability

This optional filing can be made after five years of continuous use. It provides a higher level of legal protection, making the mark immune to certain challenges, such as claims that it is “merely descriptive.”

Canada Trademark Application and Ownership Forms

The Canadian Intellectual Property Office (CIPO) manages trademarks under the Trademarks Act. Recent reforms have streamlined many of these processes, though strict adherence to classification is still required.

CIPO Online Trademark Application and Class Fees

The initial filing requires a representation of the mark and a list of goods and services organized by Nice Class.

• Pricing Structure: C$347.35 for the first class and approximately C$105 for each additional class.
• Common Pitfalls: Failing to provide a clear description of nontraditional marks, such as 3D shapes or sounds.

Assignment and Change of Ownership Recordal

When a brand is sold or a company merges, this form updates the Trademarks Register to reflect the new proprietor.

• Key Detail: While CIPO does not always require the full signed assignment document, it is best practice to have a legal transfer of “goodwill” documented to ensure the mark remains valid under common law.

Section 45 Non-Use Cancellation Proceedings

This is a unique “use it or lose it” mechanism. Any third party can request that the Registrar require an owner to prove they have used their mark within the last three years.

• Consequence: If the owner cannot provide an affidavit and evidence of use (invoices, advertisements, etc.), the mark may be expunged from the register.

Essential Supporting Documentation for Trademark Filings

Beyond official forms, several legal documents are used to overcome obstacles or provide necessary evidence during the registration process.

Trademark Clearance Search Reports

Conducted prior to application, these reports identify potential conflicts. While not filed with the government, they are vital for showing that a brand owner acted in “good faith” and did not willfully infringe on another’s rights.

Consent and Coexistence Agreements

If an examiner cites a “likelihood of confusion” with another mark, the two parties can sign a Coexistence Agreement.

• Effectiveness: These agreements are highly persuasive. They outline how the two brands will stay in their own “lanes” (e.g., using different colors or selling in different geographic regions) to avoid confusing the public.

Office Action Response Submissions

When an examiner issues a “refusal” or “report,” the applicant must file a formal response. This document often contains legal arguments, case law citations, and additional evidence (like sales figures or advertising spend) to prove the mark deserves registration.

Navigating Legal Risks, Challenges, and Enforcement

A trademark is a “living” asset that requires proactive management. Beyond the initial filing, brand owners must navigate potential refusals, defend against third-party challenges, and maintain the mark’s validity through consistent commercial use.

Common Grounds for Refusal

Trademark offices act as gatekeepers, refusing applications that fail to meet distinctiveness standards or conflict with existing rights.

• Likelihood of Confusion (Relative Grounds): The most common refusal occurs when a mark is confusingly similar to an existing registration (U.S. Lanham Act § 2(d); Canada Trademarks Act s. 12(1)(d)). Examiners compare sound, appearance, and market channels.
  • Example: “SUN-KIST” for juice would likely be refused due to the famous “SUNKIST” beverage mark.
• Descriptiveness and Genericness (Absolute Grounds): Marks that merely describe a product’s feature (e.g., “CREAMY” for yogurt) are refused unless they have “acquired distinctiveness.” Generic terms (the common name of the product) can never be registered.
• Geographic and Surname Issues: Marks primarily denoting a geographic location or a common surname are generally restricted. You must prove “secondary meaning”—that consumers see the name as a brand, not just a place or person.
• Deceptive Matter and False Connection: Marks that falsely suggest an affiliation with famous individuals, institutions, or government bodies are prohibited. If a misdescription is “material” to a consumer’s decision, it is an incurable bar.
• Functional Features (Trade Dress): If a 3D shape or design is utilitarian (essential to the product’s function), it cannot be trademarked. This prevents companies from using trademarks to bypass the expiration of patents.
• Failure to Function: In the U.S., purely ornamental designs or common slogans (e.g., “World’s Best Dad”) may be refused because consumers do not perceive them as source identifiers.

Opposition and Cancellation Risks

Even after approval, a mark remains vulnerable to challenges from third parties who believe the registration harms their interests.

• Opposition (Pre-Registration): Once a mark is published (U.S.) or advertised (Canada), third parties have a specific window to object. Opposers often cite prior rights, descriptiveness, or “bad faith” (e.g., squatting).
  • Burden of Proof: The opposer must generally prove their case by a “preponderance of evidence.”
• Cancellation (Post-Registration): Marks can be challenged even after they are registered.
  • Abandonment: In both the U.S. and Canada, three consecutive years of non-use is typically considered prima facie evidence of abandonment.
  • Genericide: If a mark becomes the common word for a product (e.g., “Escalator”), it can be cancelled at any time.
  • Incontestability: In the U.S., after five years of continuous use, a mark can become “incontestable,” shielding it from challenges based on descriptiveness or prior use.

Post-Registration Maintenance and Vigilance

Owning a registration is a responsibility. Failure to maintain or police the mark can lead to a total loss of rights.

• Mandatory “Proof of Use” Filings: * U.S. Section 8: Registrants must file an affidavit of continued use between the 5th and 6th year of registration.
  • Canada Section 45: While no routine filing is required, third parties can request “summary expungement” if you cannot prove use within the last three years.
• Active Policing and Monitoring: Owners should use “watch services” to identify infringing applications early. Enforcement tools include Cease & Desist letters, UDRP proceedings for domain names, and recording marks with Customs (CBP in the U.S.; CBSA in Canada) to stop counterfeit imports.
• Quality Control in Licensing: If you license your mark, you must exercise “quality control.” “Naked licensing” (licensing without supervision) can result in the mark being deemed abandoned because it no longer guarantees a consistent source of quality.
• Proper Notice: Always use the ® symbol for registered marks and ™ for unregistered ones. Correct usage (using the mark as an adjective, not a noun or verb) is the best defense against genericide.

Final Thoughts

A registered trademark in the U.S. or Canada grants enforceable legal rights that are critical to protecting a business’s brand. In the U.S., that includes nationwide presumptions of ownership and exclusive use under the Lanham Act, along with access to federal courts and statutory remedies. In Canada, registration confirms entitlement under the Trademarks Act and shields the mark from many post-registration challenges.

The two systems differ significantly. The U.S. requires use in commerce or a demonstrated intent to use, with strict maintenance filings under Sections 8 and 15 to avoid cancellation. Canada imposes no use requirement at filing, but increasingly rejects marks lacking inherent distinctiveness. In both countries, applicants must be prepared to overcome refusals for confusion, descriptiveness, or other statutory bars. Mistakes like vague goods descriptions, improper specimens, or missed deadlines can lead to refusal, abandonment, or cancellation. Conversely, precise compliance and proactive brand management preserve and strengthen trademark rights over time.

Trademark registration is a regulatory gate that opens legal remedies. Businesses that secure and maintain registrations in the U.S. and Canada place themselves in the strongest possible position to deter infringement, enforce their rights, and protect long-term brand value.

FAQs

What happens if we stop using our trademark after it’s registered?

Stopping use can jeopardize your rights. In the U.S., if you cease use of the mark for three consecutive years, it creates a presumption that you’ve abandoned the mark. An abandoned mark loses its protection – meaning your registration can be canceled and you can no longer claim exclusive rights. You might keep the registration formally up to the next maintenance deadline, but if challenged (in a cancellation proceeding or as a defense by an alleged infringer), you could lose because of non-use.

In Canada, if you stop using a registered mark, after three years any party can initiate a Section 45 proceeding requiring you to prove use; if you can’t show use (or excusable reasons for non-use) in that period, your registration will be expunged.

In either country, even without formal challenge, prolonged non-use erodes your ability to enforce the mark – courts won’t issue injunctions for marks not in use. If you discontinue a product line or service, it’s advisable to either resume use within a reasonable time or accept that the trademark rights will fade. Token use to preserve rights may be insufficient under U.S. law, which requires bona fide use in the ordinary course of trade.

Do U.S. and Canadian trademark registrations protect my brand in other countries?

No, trademark rights are territorial. A U.S. registration grants rights only within the United States and its territories, and a Canadian registration grants rights only throughout Canada. Each country has its own trademark system.

If you need protection in other markets (e.g., Europe, Asia, Latin America), you must apply in those jurisdictions directly or through international systems like the Madrid Protocol. The Paris Convention allows you to use your U.S./Canadian filing date as a priority date for filings in other member countries within 6 months. However, there’s no such thing as a global trademark registration.

If I have a U.S. trademark, can I stop someone in Canada (or vice versa) from using it?

Generally, no, you can’t enforce a U.S. trademark in Canadian courts and vice versa. Trademark rights don’t cross borders. However, if someone abroad targets your domestic market (e.g., sells into the U.S. via a website), your U.S. trademark might help block imports or sales in the U.S., but not activity confined within Canada.

To stop use in another country’s domestic market, you need rights in that country. Many companies register in both countries for this reason, especially those active in the U.S.–Canada trade.

How can I enforce my trademark against an infringer in another country?

You need local trademark rights in that country. For example, to stop a company in Germany, you must rely on a valid German or EU registration. If you don’t have one, your options are limited unless your mark qualifies as “well-known” under local law.

For online infringement, U.S. or Canadian courts can sometimes issue orders affecting domain names or platforms, but for physical businesses, enforcement must occur through the local legal system. For e-commerce, takedown mechanisms on platforms like Amazon or eBay are often the first step.

What is the benefit of an “incontestable” status in the U.S.?

After five years of continuous use, a U.S. trademark owner can file a Section 15 Declaration to make the registration incontestable. This means certain defenses—such as the claim that the mark is merely descriptive—can no longer be raised in court.

Incontestable status strengthens your ability to enforce the mark and narrows the grounds on which infringers can attack it. However, it doesn’t make the mark immune to cancellation for reasons like abandonment or genericide. Canada does not offer an equivalent status.

If I register my trademark, does that mean I can stop others from using the domain name?

Yes, but only under specific conditions. You can use procedures like the UDRP (Uniform Domain Name Dispute Resolution Policy) to recover domains that are confusingly similar to your trademark, especially if they were registered and used in bad faith.

A registered trademark supports your case in these disputes. For country-specific domains (like .ca), similar rules apply, though requirements may vary. If someone uses a domain for legitimate purposes unrelated to your brand, you may not be able to claim it. In cases of commercial misuse or phishing, court action may also be available.

How do the U.S. and Canada handle international priority, and what if two people in different countries have the same mark?

Both countries honor international priority under the Paris Convention. If you file in one country and then in another within six months, you can claim the earlier filing date. This can help win conflicts where filing timing is critical.

If two businesses independently use the same mark in different countries, each may retain rights locally. Problems arise when one enters the other’s market. In such cases, options include coexistence agreements, buying out rights, or rebranding. There is no automatic cross-border resolution.
