Is This for You?

A trademark registered in one country does not protect you in another.

We recommend coverage in every market where you sell.

  • YOU SELL IN BOTH CANADA AND THE US WITH ONLY ONE REGISTRATION

    • A trademark registered in the US does not protect your brand in Canada, and a Canadian registration does not protect you in the US. These are separate legal systems with separate registration requirements, examination processes, and enforcement mechanisms.
    • If you have only one registration, you have an uncovered market.
    • A competitor can register your brand name in the unprotected country even while you are actively selling there.
  • YOUR BRAND IS EXPANDING INTO INTERNATIONAL MARKETS

    • Growth into Europe, Asia, or other markets requires trademark registrations in those markets.
    • The Madrid System, administered by the World Intellectual Property Organization, allows you to file a single international application that designates multiple member countries.
    • It is not free and it is not guaranteed, but it is more efficient than filing separately in each country.
    • A lawyer who understands the Madrid System can help you decide which countries to designate and in what sequence.
  • A TRADEMARK SQUATTER HAS YOUR BRAND NAME IN ANOTHER COUNTRY

    • Each country sets the conditions for filing and registering trademarks in its own legislation (Paris Convention, art. 6(1)).
    • Where another party registers your brand name first, your options depend on that country's law; in Canada, for example, a registration is invalid if the application was filed in bad faith (Trademarks Act, s. 18(1)(e)).
    • An international trademark lawyer can advise on the realistic options for recovering the name or entering the market under a modified form.
  • YOU WANT ONE LAWYER TO HANDLE BOTH CANADA AND THE US

    • We recommend coordinating US and Canadian filings on timing, class selection, and brand strategy.
    • I hold bar admissions in California, Ontario, and Quebec.
    • I file US and Canadian trademark applications; Canadian examiner's reports, oppositions, and section 45 proceedings are handled through a licensed Canadian trademark agent.

Trademark rights are territorial: a registration in one country does not protect you in another.We recommend filing early in each market where you sell.

Two Countries, One Law Firm

  • Multi-country clearance from one search

    Before filing in any country, I search existing registrations and pending applications in each target market. A name that is clear in the US may be registered in Canada or the EU by a third party. One clearance process covering all your target markets prevents the discovery problem after you have already committed to the brand internationally.

  • US and Canadian filings from one attorney

    I file and prosecute USPTO applications in the United States and assist clients with CIPO applications in Canada. For brands operating across the Canada-US border, this means one consistent strategy, one timeline, and one point of contact for both filings. I respond to USPTO office actions; in Canada, responses to examiner's reports are handled through a licensed Canadian trademark agent.

  • Madrid System filing for broader coverage

    For coverage beyond the US and Canada, I prepare and file international applications through the Madrid System administered by WIPO. Madrid designations allow one filing to cover multiple member countries through their national trademark offices. I advise on country selection, class coordination, and timeline expectations for each designated market.

  • Watching and enforcement across markets

    International trademark ownership requires watching for conflicting filings and infringing uses in each registered market. A watch for new applications and commercial uses in other markets that conflict with your registrations is available as a scoped add-on, and I advise on appropriate responses.

US, Canada, and Beyond

I hold bar admissions in California, Ontario, and Quebec. I file US and Canadian trademark applications; Canadian examiner's reports, oppositions, and section 45 proceedings are handled through a licensed Canadian trademark agent. For brands expanding further, I coordinate Madrid Protocol filings through WIPO for broader coverage in Europe, Asia, and other markets. That keeps the filing strategy consistent across jurisdictions.

Common Questions

Do I need separate trademark registrations in every country where I sell?

Yes. Under the Paris Convention, a mark duly registered in one member country is independent of marks registered in the other member countries (art. 6(3)). The US and Canada are separate systems, and Europe has both the EU trademark and national filings. The Madrid System, administered by WIPO, allows you to file a single international application that designates multiple members. We recommend prioritizing the markets where you sell and where counterfeiting risk is highest rather than trying to cover every country at once.

Can one lawyer really file in both the US and Canada?

Yes. I hold bar admissions in California, Ontario, and Quebec. I file with the USPTO in the United States and the CIPO in Canada; Canadian examiner's reports, oppositions, and section 45 proceedings are handled through a licensed Canadian trademark agent. For brands that operate across the border, that keeps the filing strategy consistent.

What is the Madrid Protocol, and is it the right choice for my situation?

The Madrid Protocol is an international treaty administered by WIPO that allows trademark owners to file a single international application designating multiple Madrid System members. The application must be based on an application or registration at the office of a Madrid member where the applicant is a national, is domiciled, or has a real and effective industrial or commercial establishment. Coverage is not automatic: each designated office examines the application under its own law and can refuse it within the treaty time limits. We recommend comparing the cost of Madrid and direct national filing for each country before you choose.

How much does international trademark protection cost compared to domestic?

Our legal fee for a straightforward single-class US application is $2,995 (Brand Locked), plus the USPTO base fee for an electronic application of US$350 per class (37 C.F.R. § 2.6(a)(1)(iii)) and any applicable surcharges; each additional class is $750. Canadian CIPO applications carry CIPO's own government fees. Madrid Protocol filings involve a WIPO basic fee plus fees for each designated member, which vary by member and number of classes; our Madrid tiers start at $4,495 (Madrid Foundation: three designations, one class), plus government fees. I quote a flat fee before any work begins.

What happens if someone registered my brand name in another country before me?

Each country sets the conditions for filing and registering trademarks in its own legislation (Paris Convention, art. 6(1)). In Canada, for example, a registration is invalid if the application was filed in bad faith (Trademarks Act, s. 18(1)(e)). If a domain name is involved, the UDRP provides a mandatory administrative proceeding in which the complainant must prove that the domain name is identical or confusingly similar to a mark in which it has rights, that the registrant has no rights or legitimate interests in it, and that it has been registered and is being used in bad faith (UDRP ¶ 4(a)). Where a challenge is not available, we recommend assessing whether to enter the market under a different name.

How do I protect my trademark in Europe?

The European Union Intellectual Property Office (EUIPO) administers the EU trademark (EUTM), a single registration that covers all 27 EU member states. You can file directly with the EUIPO or designate the EU through a Madrid Protocol filing. For European countries not covered by the EU trademark (Norway, Switzerland, UK post-Brexit), separate filings are required. UK trademark filings are handled through the UK Intellectual Property Office. I advise on EU and UK strategy as part of a broader international trademark plan.

What is a first-to-file trademark system, and why does it matter?

Each country sets the conditions for filing and registering trademarks in its own legislation (Paris Convention, art. 6(1)). In the US, the Lanham Act defines a trademark to include any word, name, symbol, or device used by a person to identify and distinguish their goods, so rights can exist through use without registration (15 U.S.C. § 1127). In Canada, an applicant is not entitled to register a trademark that, at the earlier of its filing date and its date of first use in Canada, was confusing with a trademark previously used or made known in Canada by another person (Trademarks Act, s. 16(1)), unless that trademark has been abandoned on the day the application is advertised (s. 16(3)). We recommend filing in your key markets before you launch publicly in those markets.

Can I use my US trademark registration to protect myself in Canada?

No. A USPTO registration is limited in scope to the United States. A Canadian registration issued by the CIPO is required to claim registered trademark rights in Canada. That said, if you can show that your US mark has become well-known in Canada through cross-border advertising, spillover reputation, or Canadian consumer recognition, Canadian law may provide some protection against confusing adoption of your mark by a Canadian party. This protection is more limited and harder to enforce than a direct registration.

What is the difference between the USPTO and CIPO?

The USPTO (United States Patent and Trademark Office) administers trademark registrations in the United States. The CIPO (Canadian Intellectual Property Office) administers trademark registrations in Canada. Both require separate applications with separate fees, class selections, examination processes, and filing timelines. The US system allows filing based on actual use or intent to use. The Canadian system places heavier weight on registration following 2019 amendments. The two systems are not interchangeable and do not recognize each other's registrations.

How long does international trademark registration take?

The timeline varies by country. A US application for the Principal Register filed with the USPTO is examined and, if approved, published for opposition before it can register. For fiscal year 2024–2025, Canada's CIPO published an average turnaround time of 34.5 months for trademark registrations. Madrid Protocol designations are examined by each country's national office under its own law, and an office that wishes to refuse protection must notify WIPO of the refusal, with all its grounds, within one year from the date WIPO sent it notice of the designation, or within 18 months where the designated member has made the declaration allowing it; a member that has also so declared may notify an opposition-based refusal after the 18 months only if it told WIPO of possible later oppositions before the 18 months ran out and notifies the refusal within one month after the opposition period ends and no later than seven months after that period begins (Madrid Protocol, art. 5(2)). I provide timeline estimates for each target market before filing.
