You launch a website. You ship to Canada, the UK, and Australia. You register your US Trademark. You feel safe.

Here is the cold water: Your US Trademark stops at the US border.

If someone in Canada registers your name tomorrow, they own it in Canada. You could be sued for shipping your own product to Toronto. If someone in China registers your name, they can seize your goods at the factory gate before they even leave the country.

There is no such thing as a “World Trademark.” Every country is a separate legal island. You have to buy a ticket for every island you want to visit.

Don’t Buy the Whole World

New clients often panic and say, “I need to trademark everywhere!” We say: “No, you don’t. You need to trademark where you make money.”

International filing is expensive. If you file in every country, you will go bankrupt before you sell your first widget. We use the “Revenue & Risk” model to decide where to file:

1. The Home Base (USA): Mandatory. This is your foundation.
2. The Factory (China/Vietnam): Critical. In many countries (like China), if you don’t own the trademark, “squatters” can legally block your factory from exporting your own goods.
3. The Key Markets: Where are your customers? If 20% of your sales come from the UK, file in the UK. If you sell zero units in Brazil, ignore Brazil.

Plain English Explanation

International trademark law operates on a country-by-country basis, meaning a brand name is only protected in the specific nations where it is officially registered. If a business expands its manufacturing or sales overseas without securing local trademark rights, it risks losing its brand to foreign competitors or facing legal action for selling its own products. Centralized treaties now allow businesses to apply for these protections across multiple international borders through a single, streamlined process.

How to File: The “Madrid Protocol” (The Easy Button)

In the old days, you had to hire a separate lawyer in every single country.

• Lawyer in France: €2,000.
• Lawyer in Japan: ¥300,000.
• Headache: Infinite.

Today, we use the Madrid Protocol. It is a centralized treaty that lets us file one application through the USPTO to reach over 120 countries (including the EU, UK, China, and Australia).  You pay a “Base Fee” to the World Intellectual Property Organization (WIPO), plus a fee for each country you add. The USPTO Base is $600 per class.  

The TL; DR Summary

A US trademark only protects your brand inside the United States. You must register your trademark in the specific countries where you manufacture goods and sell to customers. The Madrid Protocol is a centralized system that allows you to apply for protection in multiple countries using a single application.

Key Takeaways

• File international trademarks based on a revenue and risk strategy rather than trying to register globally.
• Secure your trademark in manufacturing countries to prevent local entities from seizing your exported goods.
• Use the Madrid Protocol to bypass the need to hire individual lawyers in every foreign market you wish to enter.
