Here is a conversation we have more often than we would like. A seller has built a real brand in the US, done everything right, and is ready to open in a new country. Inventory is on the water. And they find out that somebody else registered their brand name there eighteen months ago and is waiting.
The seller’s reaction is almost always the same: but I have a US trademark. That is true, and it is the problem.
Rights are territorial, and that is not a technicality
A US trademark registration is granted under US law. Its protection runs to the US market. It is strong evidence of your rights here and it does not reach across a border on its own.
There is no single registration that covers everywhere. This surprises people, because the internet does not feel territorial. Your listing is visible from anywhere, so it feels like your brand is protected everywhere. Those are two different things.
What sellers actually run into
In practice, the problem shows up like this. A seller decides to expand, gets ready to launch, and discovers their brand name is already registered in that market to somebody they have never heard of.
Sometimes that is a coincidence. Sometimes it is not. There are people who watch which US brands are growing and file those names in other markets ahead of them, then wait for the brand to arrive. Whether a filing like that can be challenged, and on what grounds, depends entirely on the country and the facts, and it is a question for a lawyer qualified in that country.
What is consistent is the position it puts you in. You are choosing between buying your own name back, rebranding for that market, or a dispute in a system you have no experience with, and you are doing it with inventory already moving.
Timing is the part that actually costs money
File before you announce. Not before you ship, before you announce.
Expansion plans leak in ordinary ways. You mention the new market on a podcast, in a seller group, in a job posting, to a supplier. That is lead time for somebody else, and the gap between deciding to expand and being publicly visible about it is usually the cheapest window you will ever have to get your filings in.
There is a practical reason too. Amazon’s Brand Registry protections work off registrations, and the enforcement tools available in a given marketplace generally depend on having a registration that covers it. Without one, you are opening a store in a new country with none of the tools you rely on at home.
How this should be handled
The right strategy depends on which markets you are entering and in what order. Depending on the markets, there may be routes that let you build on your existing US filing rather than starting from scratch in each country. Which of those are open to you, and what they require, is a question for counsel qualified in those jurisdictions.
That is how we handle it. We work with attorneys in the countries our clients are expanding into, and we coordinate the US side of the portfolio so the pieces line up rather than being filed one at a time by whoever was closest.
One more thing worth thinking about, which sellers rarely do until it is a problem. If your product is manufactured outside the United States, that country deserves its own consideration even if you never sell there.
If someone already filed your brand
It is not automatically over, but it is now a real matter rather than a form. Depending on the country and the facts there may be options, and all of them take time you probably do not have if the inventory is already moving.
Which is the argument for doing this in the quiet part, when it is a decision instead of an emergency.
If you are planning an expansion in the next year, mapping the filings you need and the order to make them in is work we do with sellers, and we bring in local counsel where the work belongs to them. This article is general information, not legal advice.
