A growing company receives a UDRP complaint targeting its .co domain — a domain it registered years before the complainant ever filed a trademark application. The complaint alleges bad faith. The registrant has done nothing wrong. What happens next depends entirely on how the defense is built.
When a registrant holds a .co domain that predates the complainant's trademark rights, the UDRP's bad-faith requirement — that the domain was registered and used in bad faith — becomes the respondent's strongest shield. Under Paragraph 4(a)(iii), a panel cannot find bad faith in a registration that preceded the mark. The key is assembling a record that proves the timeline and documents legitimate interest. In the matter described here, that record produced a defense victory and a finding of Reverse Domain Name Hijacking.
This case study traces the situation, the strategy, and the outcome — and explains what evidence actually decided the result.
What Was the Situation?
The registrant, a small technology consultancy, had held a two-word .co domain for approximately four years before the complaint arrived. The domain matched its trading name. The registrant used it as its primary website, displayed the name on client invoices, and had earned modest but documented revenue under that name since year one of registration.
The complainant was a company in an adjacent sector that had registered a similar trademark roughly eighteen months after the respondent acquired the domain. It filed a UDRP complaint at WIPO, alleging that the registrant had targeted its brand and was operating in bad faith by creating consumer confusion. The complaint pointed to the similarity of the domain to its mark and the overlap in services.
What the complaint did not address — and appeared to assume the panel would not scrutinize — was the registration date. The domain predated the trademark application by more than two years. It predated the trademark registration by nearly three. In our practice, this is the precise fact pattern where an aggressive complainant overreaches and a careful respondent wins.
What Did the Firm Do?
We were engaged shortly after the complaint was filed. The respondent had 20 days to file a response from the date the case commenced. That window is set by the UDRP Rules and does not extend by default. Acting quickly mattered.
The first step was building the registration timeline in documentary form. We obtained archived WHOIS records, registration confirmation emails, and early invoices bearing the domain and trading name. Wayback Machine captures of the website were secured from the earliest available date. Taken together, these established that the registrant's use of the name long preceded any rights the complainant could claim.
The second step was constructing the legitimate-interest record under Paragraph 4(c) of the UDRP. Three safe harbors are available. The most relevant here: a bona fide offering of goods or services before any notice of the dispute. We documented the consultancy's client engagements, invoicing history, and public-facing presence under the name — all predating the complainant's trademark application. We also noted that the registrant was commonly known by the domain name within its client network, satisfying a second safe-harbor branch.
The third step was the RDNH argument. Reverse Domain Name Hijacking — a formal finding that a complaint was brought in bad faith to deprive a legitimate registrant — requires showing that the complainant knew, or should have known upon basic diligence, that the claim could not succeed. Here, the complainant's own trademark registration certificate bore a date that the respondent's registration predated by nearly three years. A simple WHOIS check at the time of filing would have disclosed that gap. The complainant's counsel had access to that certificate. The inference that the complaint was filed despite knowledge of that timeline was, in our assessment, supportable.

What Was the Outcome?
The single-member panel denied the complaint in full. On the first element, the panel found sufficient similarity to proceed — a standard result when domain and mark share a common word. On the second element, the panel held that the registrant's pre-complaint use of the name in a bona fide business satisfied Paragraph 4(c) and established legitimate interest. The complaint failed there. It also failed on the third element: the panel found that bad faith at the time of registration was impossible to establish when the domain was registered before the complainant's mark even existed.
The panel then turned to RDNH. It found that the complainant, represented by counsel, had filed knowing — or being reckless as to the fact — that the domain predated the mark. That knowledge, combined with the absence of any explanation in the complaint for the timeline discrepancy, supported the conclusion that the filing was an attempt to use the Policy as an instrument of acquisition rather than protection. The RDNH finding was recorded in the published decision.
No monetary penalty attached to the RDNH finding — the UDRP provides none — but the reputational and strategic value was real. The registrant's domain remained registered in its name. The complainant's public record now includes an RDNH finding by a WIPO-appointed panel.
In a recent matter of this kind (a .co domain dispute, autumn 2025), we built a comparable record for a registrant who had held the name for several years and had done business under it continuously. The response was filed within the 20-day window. The complaint was denied. No transfer occurred.

What Evidence Decides a Pre-Trademark Defense?
Pre-trademark registration date defenses succeed or fail on documentation, not argument. Panels consider the registration date of the domain against the trademark priority date — application date, not registration date, if the complainant can assert common-law rights from an even earlier period. That means the respondent must account for the complainant's possible common-law use, not only the filing date on the trademark certificate.
The records that consistently carry weight are: domain registration confirmation with a timestamped date; early website archives; business formation documents naming the domain or trading name; client-facing materials — invoices, proposals, correspondence — bearing the domain; and any industry directory listings or press references predating the dispute. The stronger the commercial use evidence, the stronger the Paragraph 4(c) bona fide offering argument.
RDNH is a separate assessment. It requires showing that the complainant knew, or should upon reasonable diligence have known, that the complaint lacked merit. The threshold is not low. Panels decline to make RDNH findings when a complainant had a colorable argument, even one that ultimately failed. But where the timeline gap is obvious from publicly available records — as it was here — and where the complainant's own trademark certificate discloses the relevant dates, the argument is well-founded.
The .co zone is administered through WIPO under the UDRP, which means the same substantive test applies as for .com disputes. Procedurally and doctrinally, there is no meaningful distinction. The three elements, the safe harbors, and the RDNH standard are identical. What does differ is the commercial profile of .co: it is used heavily by international companies, including many in Latin America, South Asia, and Europe, and panels are familiar with registrants who hold .co domains for legitimate business purposes entirely separate from any US or EU trademark landscape.

Case Summary: Frequently Asked Questions
What was the situation?
A technology consultancy held a .co domain it had registered approximately four years before the complainant's trademark was applied for. The complainant filed a UDRP complaint at WIPO alleging bad faith. The domain matched the respondent's trading name and had been used commercially since the date of registration.
What did the firm do?
COGNOMEN assembled documentary evidence of the registration date, archived website records, invoicing history, and client-facing materials predating the complaint. We built the legitimate-interest record under Paragraph 4(c) of the UDRP and presented a supported RDNH argument, demonstrating that the complainant's trademark postdated the domain by nearly three years — a fact discernible from the certificate itself.
What was the outcome?
The single-member WIPO panel denied the complaint on the second and third UDRP elements. The panel found the registrant had a bona fide interest and that bad faith at registration was legally impossible given the pre-trademark registration date. The panel also made a Reverse Domain Name Hijacking finding. The domain remained with the registrant.
