Step-by-step: prove a legitimate interest in your .cn domain

A demand letter arrives. A Chinese-language complaint lands at ADNDRC. Someone claims your .cn domain infringes their trademark, and you have a limited window to answer before a default transfers the name away. The question is not whether to respond – it is whether you can prove a legitimate interest quickly enough and completely enough to survive the panel's scrutiny.

To defend a .cn domain under the CNNIC dispute procedure administered through ADNDRC, a registrant must demonstrate a legitimate interest or right in the disputed name – the mirror of Paragraph 4(c) of the UDRP, adapted to China's national rules. The registrant has 20 days to file a response once the case commences. The governing standard tracks the three UDRP elements closely, but .cn carries its own eligibility, language, and evidentiary expectations that differ from a .com defense.

This guide walks each step of that defense, flags the trap hidden inside each one, and explains when an RDNH finding – a finding that the complaint itself was abusive – is a realistic outcome worth pursuing.

What procedure governs .cn domain disputes, and how does it differ from the UDRP?

CNNIC – China's country-code registry – operates its own dispute resolution policy, and ADNDRC (the Asian Domain Name Dispute Resolution Centre) is among its authorized providers. The procedure tracks the UDRP's three-element structure: the complainant must show (1) identity or confusing similarity to a mark, (2) no legitimate right or interest in the registrant, and (3) registration or use in bad faith. That final element matters. Where the UDRP reads "registered and used" in bad faith – a cumulative requirement – the CNNIC rules, like several ccTLD procedures, may find bad faith established by registration or use in bad faith. That lower conjunctive bar means a registrant who acquired the domain legitimately but later pointed it at a parked page can face a stronger complaint than the same fact pattern would generate at WIPO for a .com.

The practical consequence is that the defense must address both the moment of registration and the current use of the domain. A gap in either creates a vulnerability. We regularly advise registrants who assume that good-faith registration, on its own, closes the case – under CNNIC rules, it may not.

The proceedings are conducted in Chinese by default, though the provider may allow other languages in appropriate circumstances. That language question is not minor. Filing an inadequate response in the wrong language, or filing in English when the complainant filed in Chinese, can forfeit procedural rights or reduce the panel's confidence in the registrant's position. Confirm the procedural language with counsel before preparing any materials.

Step 1: Understand the timeline before anything else

The response window opens when the case formally commences, not when you first receive notice. A registrant has 20 days to file a response. Missing that window means a default – and a default means the panel decides on the complainant's record alone. Panels deciding on defaults rarely transfer domains without some supporting evidence of bad faith, but a complete, well-evidenced defense is far more reliable than relying on a complainant's record being insufficient.

What is the trap? Many registrants lose the first ten days to translation delays, to locating the original registration documents, or to the mistaken belief that the complaint lacks merit and therefore needs no response. Lack of merit is a legal conclusion. It is not a substitute for filed evidence. Start assembling your record on day one.

The realistic timeline for a well-prepared defense looks like this. Days one through three: identify all registration-era documents (domain order receipts, business registration certificates, correspondence referencing the domain). Days four through seven: obtain translations if needed and draft the substantive response. Days eight through fifteen: finalize, review, and prepare any supplemental exhibits. Days sixteen through twenty: file. That schedule leaves no slack for complications.

Step 2: Map your case onto the Paragraph 4(c) safe harbors

The UDRP's Paragraph 4(c) safe harbors – and their CNNIC equivalents – describe three categories of legitimate interest: (a) a bona fide offering of goods or services before you received notice of the dispute; (b) being commonly known by the domain name; and (c) legitimate noncommercial or fair use without intent to divert consumers or tarnish the mark. Each is a distinct legal pathway, and the trap is treating them as interchangeable.

Bona fide use before notice. This is the strongest safe harbor when it applies. The word "before" is critical. Use that began after the complainant filed – or, critically, after the complainant sent a demand letter – will not qualify. Panels look for evidence of the domain's commercial use that predates any notice: invoices, website screenshots, product listings, marketing materials, customer correspondence, or registration of a related business entity. Each item should carry a verifiable date. Undated screenshots are worth almost nothing. A timestamped web archive, an original invoice with a date, or a business registration certificate with a registration date is worth a great deal.

Commonly known by the name. This safe harbor applies when the registrant – as an individual, business, or organization – is identified by the domain name independently of the complainant's trademark. The evidence here is corporate or business registration, product packaging, trade press coverage, or correspondence addressed to the registrant using the name. The trap is that "commonly known" means known to others, not known to oneself. A single internal document calling the business by the name is not enough.

Legitimate noncommercial or fair use. Commentary, criticism, fan sites, and informational domains can qualify – but commercial use alongside the commentary will undermine the argument. If the domain carries advertising, particularly pay-per-click advertising related to the complainant's industry, panels are unlikely to accept the fair-use defense. The .cn context adds an additional consideration: content must be consistent with applicable Chinese regulations, which restrict certain types of speech and certain commercial structures. A site blocked inside China may be viewed differently than one accessible to domestic users.

Step 3: Build the legitimate-interest record – evidence by evidence

The response is only as strong as the documents behind it. Panels reviewing .cn disputes look for contemporaneous, verifiable evidence – not after-the-fact explanations. This is the most demanding step, and the one where registrants most often fall short.

Assemble your evidence in five categories.

• Business registration. The company or individual business registration that uses the name associated with the domain. If the business is registered in China, the Business License (营业执照) carries a registration date and a business name – both critical. If the business is registered outside China, obtain an official extract or certificate and have it translated into Chinese by a certified translator.
• Domain acquisition documentation. The original registration receipt, any domain purchase agreement if the domain was acquired through a secondary-market transaction, and any correspondence with the registrar at the time of registration. These establish when the domain was registered and under what circumstances – directly relevant to both the registration-era good faith argument and the bona fide use defense.
• Pre-notice use. Website screenshots with metadata, archived web pages from third-party archive services, customer orders, invoices, or contracts that reference the domain or the associated business name, all predating any demand letter or complaint. Each item should be accompanied by a brief explanatory note identifying the date and the source.
• Third-party corroboration. Press coverage, directory listings, business reviews, or correspondence from customers or suppliers that refer to the registrant by the domain name or the underlying business name. Third-party materials are less susceptible to a charge of self-serving fabrication.
• Trademark or other IP rights. If the registrant holds a Chinese or international trademark registration that matches or is similar to the domain, that registration is strong evidence of a right in the name. Even a pending application, if filed before the complainant's demand, is useful evidence of the registrant's intention to establish rights.

The trap at this step is producing evidence in bulk rather than in sequence. Panels do not sift through a disorganized exhibit bundle. Present the evidence in chronological order, keyed to the specific safe harbor you are arguing, with a short explanatory paragraph in the response body for each exhibit. Organized evidence reads as credible evidence.

In a recent matter – a .cn domain dispute, spring 2025 – we built a legitimate-interest record for a registrant whose domain closely matched a complainant's foreign trademark but predated that trademark's Chinese registration by nearly three years. The response organized the evidence into a timeline keyed to the registration date, the business launch date, and the complainant's first Chinese filing, in that order. The panel found for the registrant on the legitimate-interest element without reaching the bad-faith question.

Step 4: Address bad faith directly – do not leave it to the panel

Even a well-supported legitimate-interest argument may not carry the day if the response ignores the complainant's bad-faith allegations. Panels expect the registrant to engage with each allegation. Silence on a specific charge reads as an inability to answer it.

The most common bad-faith arguments in .cn disputes are: registration to sell the domain at a profit to the trademark owner; registration to disrupt the complainant's business; and passive holding of a confusingly similar domain without active use. Each requires a specific rebuttal.

On the sale allegation: if you received an unsolicited offer from the complainant and declined, or if you listed the domain for sale at a general market price without targeting the complainant, document that. A general listing at market rate is not evidence of targeting a trademark owner. An offer sent only to the complainant, at a price referencing the trademark's value, is a different matter.

On passive holding: panels have consistently held that passive holding alone is not bad faith, but passive holding of a domain confusingly similar to a well-known trademark, with no credible explanation for registration, tilts toward a bad-faith finding. The rebuttal is an explanation grounded in evidence – what was the domain intended for? What prevented its active use? Is there a business plan, a contract, or a correspondence trail that explains the gap?

On the disrupt-a-competitor allegation: the complainant must show you knew of the trademark and registered to disrupt. If the trademark was not known or registered in China at the time you registered the domain, that context is material. Chinese trademark registrations are searchable by date; if the complainant's mark postdates your registration, lead with that fact and document it.

Step 5: Assess whether an RDNH finding is realistic

Reverse Domain Name Hijacking – an RDNH finding – is a panel declaration that the complaint was filed in bad faith to deprive a legitimate registrant of a domain. It carries no monetary penalty, but it is a matter of record and carries reputational consequences for the complainant. Under the CNNIC procedure, as under the UDRP, an RDNH finding is available but is granted in a narrow range of circumstances.

When is RDNH realistic in a .cn dispute? The clearest cases involve a complainant who filed knowing the registrant had prior rights – for example, where the complainant's trademark postdates the domain registration and the complainant had actual notice of that fact. A second strong case is where the complainant's trademark is geographically or categorically remote from the domain's use and the complainant still asserted confusing similarity. A third is where the complainant filed immediately after a failed purchase negotiation, using the dispute procedure as leverage rather than as a genuine rights-enforcement mechanism.

What does RDNH require from the response? The registrant must affirmatively request the finding. A well-structured RDNH argument identifies: the specific conduct that shows the complaint was brought in bad faith; the evidence that the complainant knew or should have known its claim would fail; and the harm to the registrant from the filing. That argument belongs in a dedicated section of the response, clearly labeled and evidenced.

The trap is assuming the panel will raise RDNH on its own. Panels rarely do. If the facts support an RDNH finding, make the argument explicitly and document it. We have defended registrants in .cn disputes where the RDNH argument – not the legitimate-interest defense alone – shaped the panel's view of the entire proceeding.

What evidence decides the outcome in a .cn domain dispute?

The single most decisive factor is timing. Panels examining .cn disputes consistently resolve close cases by reference to the chronological relationship between the domain registration, the complainant's trademark rights, and the registrant's business use. A registrant who registered before the complainant's trademark filing, launched a business using the domain before receiving any notice, and holds contemporaneous documentation of both is in a strong position. A registrant who registered after the complainant's Chinese trademark issued, has no contemporaneous business use, and cannot explain the registration is not.

Secondary factors include the distinctiveness of the complainant's mark, the overlap between the domain's use and the trademark's goods or services, and the character of the registrant's website at the time of the complaint. A parked page with links related to the complainant's industry is harder to defend than a blank page. A functioning website with content predating the dispute is easier.

In a second matter from our practice – a .cn domain held by a small regional distributor, summer 2025 – the complainant alleged passive holding as evidence of bad faith. The registrant had a website, but it was thin on content and intermittently offline. We supplemented the response with archived pages, customer correspondence, and a business registration certificate showing the registrant's trade name matched the domain. The panel found legitimate interest established and declined to order a transfer. The lesson: thin evidence of use can be strengthened, but it must be documented and organized before the response is filed.
