Your U.S. Trademark Stops at the Border. You Still Don't Need One in Every Country.

Written by

No. A U.S. trademark registration protects your mark in the United States and nowhere else. And no, a SaaS company, or any company, isn't expected to hold a registration in every country where someone could open its website. Almost nobody registers everywhere. The real question is which handful of countries are worth it for your business, and when.

What a U.S. registration covers, and what it doesn't

Trademark rights are territorial. The USPTO says so directly: a U.S. patent or trademark does not afford protection in another country, and trademarks must be filed in each country where protection is sought. The Supreme Court made a similar point in 2023 in Abitron Austria GmbH v. Hetronic International, Inc., noting that in nearly all countries, including the United States, trademark law is territorial. The Court held that the Lanham Act's main infringement provisions reach only claims where the infringing use in commerce is domestic.

So if a company in Germany starts using your name for the same kind of product in Germany, your U.S. registration generally gives you nothing to enforce there. Worse, if that company registers the name in Germany or across the EU first, it may be able to object to your use there.

A U.S. registration still does real work at home, and some of that work touches international trade. A mark on the USPTO's Principal Register can be recorded with U.S. Customs and Border Protection, which has authority to detain and seize imported goods bearing an infringing mark. That protects the U.S. market from infringing imports. It doesn't give you rights in the country the goods came from.

First to use here, first to file almost everywhere else

The United States is unusual. Here, you become a trademark owner as soon as you start using your mark with your goods or services, even before registering, although those use-based rights are limited to the geographic area where you're operating. I wrote about how that plays out in prior user rights for unregistered marks.

Most of the world doesn't work that way. The U.S. International Trade Administration notes that most countries are "first to file" for trademark registration, and grant registration to the first filer regardless of first use in the market. Years of sales in a country may count for very little if someone else got to the trademark office before you.

China is the example founders hear about most. The U.S. government's guidance for exporters says China's first-to-file system allows bad-faith applicants to preempt the rights of legitimate owners, and that U.S. registration does not automatically confer rights in China. The pattern is often called trademark squatting: someone registers your brand, then holds it hostage or rides on your reputation. I covered the Chinese system and its recent changes in China's new trademark law.

The practical lesson is that in a first-to-file country, waiting until you're successful there can mean finding that someone else already owns your name.

Where it usually makes sense to file

There isn't a formula, but the same three questions come up every time.

Where do you sell now, or plan to soon? The government's advice to exporters is to be the first to file in the countries where you currently do business or are certain to do business in the future. If a meaningful share of your revenue comes from Canada, the UK or the EU, those are the natural first candidates. I went through that decision in Selling to Canada, the UK or the EU?

Where are your products made? If your goods are manufactured abroad, your brand is being put on products in that country, so it's worth asking what happens if someone else registers the name there first. That's one reason some product companies file in the country where they manufacture even when they don't sell there. The government's China guidance, for example, tells companies to protect their IP ideally before entering the market.

Where is someone likely to grab the name? The USPTO's guidance suggests registering defensively in countries where IP violations are common. Brands that are visible online, sold on global marketplaces, or easy to copy are more exposed.

If a country doesn't show up in any of those three answers, it's usually reasonable to leave it for later.

What this means for SaaS and other online businesses

A website or app is reachable from nearly anywhere, which is where the "every country" worry comes from. But being reachable isn't the same as doing business in a place, and no rule requires a registration in each country where a customer could sign up. Software companies make the same judgment call as everyone else: where are the paying customers, where is the growth plan pointed, and where would a conflict hurt most?

For a U.S. SaaS company with customers mostly in the U.S., a U.S. registration may be the only one that makes sense for a while. As revenue concentrates in specific foreign markets, those markets become filing candidates. There's also a search question that's easy to miss: a name that's clear in the U.S. may already belong to someone else in another country. Filing there isn't just about stopping others. It's also how you find out whether you can safely use the name there yourself.

Cost is the honest limit on all of this. Every country or region means government fees, often local counsel, and renewals down the road. That's why even large companies prioritize, and why "protected everywhere" isn't a realistic goal for a small business.

Timing: the six-month window after your U.S. filing

One deadline is worth knowing before you decide. Under the Paris Convention, a treaty most countries belong to, you have six months from your first trademark filing to file in other member countries and claim that first filing date as your priority date. If you file in the U.S. in January and in the EU in May, the EU application can be treated as if it were filed in January.

That window is a good moment to take stock of foreign markets, especially first-to-file ones. After it closes you can still file abroad, but you get the actual filing date.

As for how the filing gets done, there are three routes: direct national applications, regional systems like the EU's, and the Madrid Protocol, which lets you reach many countries through one application based on your U.S. filing. Those are laid out in the three ways to file abroad.
