The risk in one sentence
Owning a domain is not the same as having the right to use it, and a name that includes someone else's trademark can be transferred away from you through a dispute process, with no compensation for what you paid. This applies whether you registered the name yourself or bought it in good faith from a previous holder.
What UDRP is
The Uniform Domain-Name Dispute-Resolution Policy is an arbitration process every registrar of a generic top-level domain agrees to. A trademark holder files a complaint, an appointed panel reviews written submissions, and the outcome is a transfer, a cancellation, or a rejection. There is no court, usually no hearing, and it typically resolves in a couple of months — far faster and cheaper than litigation, which is exactly why it is used.
What a complainant has to prove
Three things together. That the domain is identical or confusingly similar to a mark they hold rights in. That you have no legitimate interest in the name. And that you registered and are using it in bad faith. All three are required, which is the main protection for legitimate holders — a name resembling a trademark is not enough on its own if you have a genuine reason to hold it.
What counts as bad faith
The recognised patterns include registering a name primarily to sell it to the trademark holder, registering to block them, a record of doing this repeatedly, and using the name to attract their customers by trading on the confusion. Note the implication for investors: offering a name for sale is ordinary business, but offering a trademark-similar name to the trademark holder is close to the textbook example of bad faith.
What protects a legitimate holder
Registering before the trademark existed is a strong position. So is a genuine use of the name unrelated to the complainant — a real business, a personal project, a common word or surname that happens to coincide. Generic and descriptive words are broadly safe even where somebody has trademarked them within a specific class, because trademark rights are narrower than they appear and do not confer ownership of ordinary language.
The checks to run before buying
Search the relevant national trademark registers for the distinctive part of the name. Search the web for existing companies using it, including in other countries. Search published UDRP decisions for the name and for close variants, which will show you if the name already has a dispute history. Then apply a plain test: could a reasonable person think this name belongs to an existing company? If yes, treat it as disqualifying rather than a bargain.
The categories to avoid outright
Misspellings of known brands. A brand name plus a generic word, in either order. A brand name in a different extension. Names for products or drugs owned by large companies. Any of these can look like an available bargain precisely because informed buyers have already passed on them, and a cheap price on a recognisable brand variant is a signal rather than an opportunity.
If a complaint arrives
Respond, and respond on time. A large share of UDRP cases are decided in the complainant's favour partly because respondents do not reply at all, and a panel deciding on one submission will usually accept it. If you have a legitimate interest, say what it is with evidence — the date of registration, the use you have made of it, why you chose it. Where real money is involved this is worth a specialist lawyer; the process is written, procedural and unforgiving of missed deadlines.
- Buying in good faith is not a defence — a domain can be transferred away regardless.
- A complainant must prove similarity, no legitimate interest, and bad faith together.
- Offering a trademark-similar name to the trademark holder is the textbook bad-faith case.
- Search trademark registers and past UDRP decisions before buying, not after.
