Someone emails you to buy a domain you have held for years. You say no. Soon they file a trademark for the same name in Europe, and maybe also in the United States. Friends say: oppose it now.
Sometimes that is right. Sometimes it wastes money. Owning the web address first is not the same as owning trademark rights. And even when opposition is the right move, it only works if you see the filing while the opposition window is still open. That is why monitoring matters as much as the legal test.
This is general information for non-lawyers, not personal legal advice. If the name matters to your business, talk to a trademark lawyer in the countries that matter before a deadline runs out.
Two fights, not one
Fight A is the trademark office. A company asks for a legal monopoly on a name for certain goods or services. You can try to stop the application while it is pending (opposition), or attack it later (usually slower and more expensive).
Fight B is the domain name. That is about who keeps the .com at the registrar. Those disputes often go through the Uniform Domain-Name Dispute-Resolution Policy (UDRP), a private process that registrars follow under ICANN rules, or sometimes through court.
You can lose Fight A and still keep the domain. You can win Fight A and still face domain pressure later. Do not treat an EU trademark certificate as automatic ownership of your website address.
When opposition makes sense
In the European Union, the European Union Intellectual Property Office (EUIPO) registers EU trade marks (EUTMs). After publication there is normally a three-month opposition window and an official fee (currently 320 euros). The main rules sit in Regulation (EU) 2017/1001, especially Articles 8 and 46.
You can usually oppose if you have an earlier trademark covering overlapping goods or services, or in some cases if you have used the name in business as a brand in a serious, more-than-local way under Article 8(4). EUIPO's own guidelines are clear: a domain registration alone is not an intellectual property right. It is a contract with your registrar. Use of the domain helps only if that use creates an unregistered trademark or similar business sign under national law. A parked or barely used domain usually fails.
The Court of Justice of the European Union made the same point in practical terms in Bud, case C-96/09 P (29 March 2011): weak local use should not block an EU-wide mark.
So:
- No commercial use and no earlier trademark: you may lack grounds to oppose the EU application. Still save every buyout email and proof of long domain ownership. That file matters more for a later domain dispute than for a weak opposition.
- Real sales of similar goods or services under the name: take the opposition deadline seriously. Early opposition is usually cheaper than later cancellation or court.
In the United States, the United States Patent and Trademark Office (USPTO) has an even shorter opposition window after publication (often 30 days). US rights do not automatically follow from an EUTM, and the reverse is also true.
Domains, UDRP, and US court
Under the UDRP, the other side must prove the domain is confusingly similar to their mark, that you lack a legitimate interest, and that you registered and used it in bad faith. Consensus views from the World Intellectual Property Organization (WIPO Overview 3.0) say that when the domain was registered before they had trademark rights, bad-faith registration is usually hard to prove. You generally cannot have targeted a brand that did not exist yet.
US federal cybersquatting law (15 U.S.C. section 1125(d), often called the ACPA) uses a similar bad-faith idea in court. An early leading case is Sporty's Farm L.L.C. v. Sportsman's Market, Inc., 202 F.3d 489 (2d Cir. 2000).
Their offer to buy your domain does not create an EU opposition right. It can still help you later on the domain track, because it shows they knew you owned the name and tried to buy it. A domain that predates their mark by decades is a very different case from one registered after their brand already existed.
The cross-border mess
A common modern picture: .com at a US registrar, first filing an EUTM, then maybe USPTO or Madrid System filings (an international route run with help from WIPO). Trademark rights are territorial. An EUTM is strong in the EU for the listed goods and services. It does not, by itself, transfer your .com. UDRP or court still has to be won on its own tests. On the other side, a US registrar does not make you immune if you sell into the EU under a colliding brand after their mark registers. Watch every office they file in. Each has its own clock.
Monitoring is the key, and early opposition is the cheap fix
Trademark offices do not call you when someone files a lookalike. They publish. A short window opens. Miss it, and you are usually left with slower, costlier tools.
That is why monitoring is the operational core of trademark defense. Opposition deadlines only help people who see the filing in time. Serious brand owners watch new filings that match or closely resemble their name, across the countries where they trade, and decide quickly whether to oppose.
Early opposition is the point. It is generally cheaper to stop a published application than to unwind a registered mark, fight infringement, or scramble after a domain complaint. The Reddit-style story often starts too late: the buyout email arrives when the cheap window is already tight or gone.
That is also what we built IP Defender to do: monitor new trademark filings across many countries and flag conflicts early, so rights holders can oppose while opposition is still available. Monitoring does not invent rights you lack. A dormant domain still will not carry a weak EU opposition. What it does is stop people with real earlier marks or real commercial use from missing the one window where the fight is meant to be fastest and cheapest.
What to do
- Watch new filings for your name where you trade. Do not rely on surprise letters.
- If you have earlier trademark rights and overlapping goods or services, calendar the opposition deadline and get advice. Oppose early when the conflict is real.
- If you only own a dormant domain, do not expect the trademark office to refuse their application just because your WHOIS is older. Preserve buyout emails and ownership proof for the domain track.
- Map every country they filed in. Deadlines differ.
- Before you change how the site is used, ask whether EU or US commercial use could create new risk once their mark registers.
Get rights where you can. Watch new filings where you trade. Oppose early when the conflict is real. Waiting for a surprise letter is the expensive path.
