Is This for You?

Trademark rights stop at the border.

Building a brand in multiple countries without country-specific registrations leaves each new market open for a local registrant to file on your name first.

  • YOUR BRAND IS SELLING OR OPERATING IN MULTIPLE COUNTRIES

    • A US trademark registration covers the United States only.
    • A Canadian registration covers Canada only.
    • Every country where you do business is a jurisdiction where a local party can file on your brand name, logo, or slogan without your knowledge.
    • International trademark protection requires country-specific filings or a coordinated multi-jurisdiction strategy built before the conflict arises.
  • YOU WANT TO FILE IN CANADA AND THE US FROM ONE ATTORNEY

    • Most trademark attorneys are licensed in one country and refer international matters to a second firm.
    • I hold bar admissions in California, Ontario, and Quebec, which means I handle both USPTO and CIPO applications directly.
    • For brands operating across the Canada-US border, that eliminates the coordination gap, the referral handoff, and the risk of two separate firms developing inconsistent filing strategies.
  • YOU NEED TO FILE IN EUROPE, ASIA, OR OTHER MARKETS

    • The Madrid Protocol allows trademark owners to file a single international application through WIPO that designates multiple countries at once.
    • A US or Canadian trademark registration is required as the base.
    • I prepare the Madrid application and coordinate with local associates in designated countries when examination requires local counsel.
  • YOUR EXPANSION IS BEING BLOCKED BY A TRADEMARK SQUATTER

    • Trademark squatters register well-known foreign brand names in local markets before the brand enters, then demand payment for the registration.
    • This is most common in first-to-file systems where use in another market does not establish rights locally.
    • The options depend on the country and whether the squatter has used the mark.
    • An international trademark attorney evaluates the cancellation or coexistence options available in each jurisdiction.

Filing in one country does not protect you in another.Every market where your brand operates is a jurisdiction where someone else can file first.

Cross-Border Trademark Filing

  • Multi-jurisdiction clearance search

    I search trademark registers across the US, Canada, and designated international jurisdictions before any filing fee is committed. The result is a legal opinion on conflict risk in each market and a recommended filing strategy. Clearance in each jurisdiction is an independent analysis: what clears in the US may not clear in Canada.

  • USPTO and CIPO applications, direct

    I file and prosecute trademark applications at the USPTO and the Canadian CIPO directly, without involving a second firm. Both systems require jurisdiction-specific specimens, descriptions of goods and services, and filing bases. I handle the full prosecution file in both countries.

  • Madrid System international filing

    The [Madrid System](https://www.wipo.int/madrid/en/) through WIPO allows a single international application to designate up to 130 countries. I prepare the Madrid application on the basis of your US or Canadian registration, select the designations that align with your business footprint, and coordinate with local associates in markets requiring local examination.

  • Cross-border infringement enforcement

    International trademark enforcement requires rights in each jurisdiction where infringement occurs. I handle enforcement in the US and Canada directly. For other jurisdictions, I coordinate with trusted local associates to pursue cease-and-desist letters, UDRP domain disputes, and platform-based takedowns across markets.

Canada, the US, and Beyond

Most trademark attorneys handle one country. I hold bar admissions in California, Ontario, and Quebec — three separate licensing bodies in two countries — and handle both USPTO and CIPO trademark applications from a single desk. For international filings beyond North America, I coordinate Madrid Protocol applications and work with trusted local associates in key markets. You get one point of contact for your entire trademark portfolio.

Common Questions

Do I need separate trademark registrations in each country?

Yes. Trademark rights are territorial — a US registration covers the United States and does not extend to Canada, the EU, or any other jurisdiction. Each country where your brand operates requires a separate national registration, or a designation through an international system like the Madrid Protocol. Planning the filing sequence early is far less expensive than addressing conflicts after a foreign market opens.

What is the Madrid Protocol?

The Madrid Protocol is an international treaty administered by WIPO that allows trademark owners to file a single international application designating up to 130 member countries. You need a home-country registration or application as the base. The international application is filed through your national trademark office and extends to each designated country, where local examination rules apply. It is typically less expensive than filing separately in each country.

Can you file in both the US and Canada without separate law firms?

Yes. I hold bar admissions in California and in Ontario, which means I handle USPTO and CIPO applications directly, without referral. For most international trademark attorneys, the Canada-US border is a referral boundary. For my clients, it is not. The two systems operate independently but are managed from the same office.

How much does international trademark registration cost?

Costs vary significantly by jurisdiction. In the US, USPTO filing fees are $250 to $350 per class. In Canada, CIPO fees start at CAD $336 per class. A Madrid Protocol application through WIPO has a base fee plus per-country designation fees, which vary by jurisdiction. I provide a flat-fee quote for each country and a total estimate before any filing begins.

What is a first-to-file trademark system?

In a first-to-file system, trademark rights go to the party who files the application first, regardless of who used the mark first. Canada and most countries outside the US operate on a first-to-file basis. This makes early international filing strategically important: a competitor who files on your brand name in a first-to-file jurisdiction before you do can acquire prior rights in that market even if you have used the mark elsewhere for years.

What is a trademark squatter?

A trademark squatter is a party that registers a well-known foreign brand name in a local market, typically in a first-to-file jurisdiction, before the brand enters that market. The goal is usually to demand payment or block the brand's entry. Options include cancellation proceedings on grounds of bad faith, negotiated coexistence, or outright purchase. The viability of each option depends on the jurisdiction and how long the squatter has held the registration.

What are the differences between US and Canadian trademark registration?

In the US, trademark rights arise from use in commerce — registration strengthens those rights but is not required to own them. In Canada, registration is the primary basis for trademark rights, which makes early filing more strategically important. Canadian applications also require a bilingual description of goods and services. Examination timelines differ: the USPTO takes 8 to 14 months; CIPO takes 18 to 24 months.

How long does it take to register a trademark internationally?

Timelines vary by country. The USPTO takes 8 to 14 months for a straightforward application. CIPO takes 18 to 24 months. A Madrid Protocol designation is subject to the national law of each designated country — most issue a decision within 12 to 18 months. EU trademark registration through the EUIPO typically takes 4 to 6 months.

Can I enforce my trademark internationally?

Enforcement requires rights in each jurisdiction where infringement occurs. I handle enforcement in the US and Canada directly. For other jurisdictions, I coordinate with trusted local trademark attorneys in the relevant markets. UDRP arbitration for domain disputes is jurisdiction-independent and can be filed for any domain registered in bad faith using your brand.

What is the Quebec trademark consideration for Canadian registrations?

Quebec's Charter of the French Language requires that trademarked words used publicly in Quebec be accompanied by a French generic term or description where the trademark is not in French. This does not affect the trademark registration itself, but it affects how the mark can be displayed on signage and in advertising within Quebec. For businesses entering the Quebec market, this is a compliance consideration alongside the CIPO filing, not instead of it.
