UDRP Legitimate Interest: The Complete Defense Guide

This guide is for respondents and their counsel. Legitimate interest is the element that decides most UDRP cases. If you have received a complaint, read the burden-shifting section first, then the safe harbour that fits your facts. If you are assessing whether to file, read the worked hypotheticals to see how panels apply the element in practice.

Quick answer: what legitimate interest means and who has to prove it

Under paragraph 4(a)(ii) of the UDRP, the complainant must prove that the respondent has no rights or legitimate interests in the disputed domain name. Proving a negative is difficult, so panels apply a burden-shifting framework: the complainant makes a prima facie case, the burden of production shifts to the respondent to come forward with relevant evidence, and the burden of proof always remains on the complainant. The respondent can satisfy the element by showing one of the three paragraph 4(c) circumstances — bona fide offering, commonly known by the domain, or legitimate noncommercial or fair use — or any other basis for rights or legitimate interests. If the respondent fails to come forward, the complainant is generally deemed to have satisfied the element. WIPO Overview 3.0, section 2.1 is the canonical statement of the framework.

Key facts at a glance

The burden-shifting framework

The complainant’s prima facie case

The complainant must first make out a prima facie case that the respondent lacks rights or legitimate interests. This is not a high bar, but it is not automatic. The complainant typically builds it from:

• WHOIS/RDDS records showing the registrant is not commonly known by the domain.
• Website captures showing a parked page, a pay-per-click landing page, or no active use.
• Search results showing no business or trading presence under the name.
• Business registry searches showing no matching entity.
• Trademark database searches showing no matching registration.
• Correspondence showing the respondent knew of the complainant’s mark.

In D2018-0552, the panel found the complainant had made a prima facie case where the respondent was not sponsored by or affiliated with the complainant, was not commonly known by the domain, and was using the domain to redirect users to sites featuring links to the complainant’s competitors. The respondent defaulted, and the panel found no basis on which the respondent could have had rights or legitimate interests.

The shift of production, not proof

The critical distinction is between the burden of production and the burden of proof. WIPO Overview 3.0, section 2.1 states:

“While the overall burden of proof in UDRP proceedings is on the complainant, panels have recognized that proving that a respondent lacks rights or legitimate interests in a domain name may result in the often impossible task of ‘proving a negative’, requiring information that is often primarily within the knowledge or control of the respondent. As such, where a complainant makes out a prima facie case that the respondent lacks rights or legitimate interests, the burden of production on this element shifts to the respondent to come forward with relevant evidence demonstrating rights or legitimate interests in the domain name. If the respondent fails to come forward with such relevant evidence, the complainant is deemed to have satisfied the second element”.

The burden of production is the obligation to come forward with evidence. The burden of proof is the obligation to persuade the panel. The shift is only of production. If the respondent comes forward with relevant evidence, the panel weighs all the evidence, and the complainant must still persuade the panel that the respondent lacks rights or legitimate interests.

The consensus view is set out in the WIPO Overview and applied consistently across providers. In D2018-0657, the panel found the complainant had established a prima facie case, shifted the burden to the respondent, and then assessed the respondent’s evidence — a brief assertion of an intention to start a technical support consulting business — and found it insufficient because it was “merely self-serving” and not supported by pre-complaint evidence.

What a prima facie case looks like

A prima facie case does not need to be overwhelming. It needs to be enough to call for an answer. The most common building blocks are:

A prima facie case built only on “the domain is similar and the respondent has not explained itself” is weaker than one built on affirmative evidence that the respondent has no plausible connection to the name. Panels are more willing to find the element satisfied where the complainant has done the work.

What happens if you stay silent

If the respondent does not come forward, the complainant is generally deemed to have satisfied the second element. This is the default rule, and it is the reason the default rate in UDRP cases is so high. The respondent’s silence is treated as a failure to discharge the burden of production, and the complainant’s prima facie case stands unrebutted.

The exception is where the complainant’s own evidence shows a legitimate interest — for example, where the domain is a dictionary word used for its ordinary meaning, or where the public record shows the respondent has a genuine business. Panels do not ignore the record, but they will not construct a defence the respondent did not raise.

WIPO Overview 3.0, section 2.1

WIPO Overview 3.0, section 2.1 is the single most-cited statement of the framework. It is cited in decisions across WIPO, Forum, ADNDRC, and CAC. The section also cross-refers to paragraph 4.6 on respondent default, confirming that the same framework applies where the respondent does not participate.

The practical lesson is simple: the respondent must come forward with evidence. The burden may have shifted only as to production, but a respondent who produces nothing loses the element by default.

A prima facie case shifts the burden to you. We test whether the complainant has actually made one — and build the evidence that rebuts it. Book a defence assessment →

Paragraph 4(c)(i): Bona fide offering of goods or services

Paragraph 4(c)(i) provides that a respondent has rights or legitimate interests if:

“before any notice to [the respondent] of the dispute, [the respondent’s] use of, or demonstrable preparations to use, the domain name or a name corresponding to the domain name in connection with a bona fide offering of goods or services”.

The provision has three moving parts: timing, use or preparations, and bona fide.

“Before any notice” — the timing rule

The use or preparations must predate notice of the dispute. Notice is not limited to the formal UDRP complaint. It can include a cease-and-desist letter, a demand email, or any communication that puts the respondent on notice that the domain is disputed.

The timing rule is strict. Evidence of use that began after notice is generally excluded from the paragraph 4(c)(i) analysis. This is why respondents should preserve dated evidence of use from the earliest possible moment.

In D2018-0657, the respondent claimed an intention to start a technical support consulting business, but the panel found the claim was not supported by pre-complaint evidence. The timing rule defeated the defence.

“Use of, or demonstrable preparations to use”

The provision covers both actual use and demonstrable preparations. Actual use is easier to prove: a live website, invoices, sales, advertising. Preparations are harder: they require documents that show a genuine intention to use the domain for a business, not a vague plan.

WIPO Overview 3.0, section 2.2 sets out non-exhaustive examples of the evidence that can support demonstrable preparations:

• Evidence of business formation-related due diligence, legal advice, or correspondence.
• Evidence of credible investment in website development or promotional materials such as advertising, letterhead, or business cards.
• Proof of a genuine (i.e., not pretextual) business plan utilising the domain name.
• Bona fide registration and use of related domain names.
• Other evidence pointing to a lack of cybersquatting intent.

The standard is inherently credible evidence, not self-serving assertions. A respondent who says “I planned to build a business” without documents has not made demonstrable preparations. A respondent who produces a signed development contract, paid invoices, and a business plan has.

“Bona fide” — what the term excludes

“Bona fide” means genuine, in good faith, and not a pretext. The term excludes:

• Use that capitalises on the complainant’s mark.
• Use that misleads consumers into thinking the respondent is affiliated with the complainant.
• Use that is primarily for the purpose of selling the domain to the complainant or a competitor.
• Use that is a sham designed to manufacture a defence.

In D2018-0657, the panel held that even if the respondent had intended to use the domain for a technical support consulting business, such use would not be bona fide because an unauthorised third party’s use of a domain identical or confusingly similar to a strong trademark in connection with unrelated goods or services cannot be bona fide if the third party does not otherwise have rights to the trademark.

The lesson is that bona fide is not just about whether the business is real. It is also about whether the use is legitimate in relation to the mark. A genuine business that trades on the complainant’s reputation is not a bona fide offering for UDRP purposes.

The evidence that proves a genuine business

The strongest evidence is contemporaneous commercial records:

A well-organised annex file with a schedule is more persuasive than a long narrative. Panels read the schedule first, and a clean, indexed file signals credibility before the panel reads a single argument.

The Oki Data test for resellers and distributors

Where the respondent is a reseller or distributor of the complainant’s goods or services, panels apply the Oki Data test. The test sets out four cumulative conditions:

1. The respondent must actually be offering the goods or services at issue.
2. The respondent must use the site to sell only the trademarked goods or services, not other goods or services.
3. The site must accurately and prominently disclose the respondent’s relationship with the trademark holder, and must not falsely claim to be an official site.
4. The respondent must not try to “corner the market” in domain names that reflect the trademark.

The conditions are cumulative. A respondent who fails any one of them does not satisfy the Oki Data test. In D2021-0258, the panel applied the test and found the respondent could not satisfy the second condition because the site was not limited to the trademarked goods.

The “Lost Mary” decision in 2025–2026 ventured a reinterpretation of the Oki Data criteria. The Czech Arbitration Court panel suggested that a disclaimer is not always necessary, provided the reseller’s website is clearly distinguishable from the trademark owner’s website. The decision is a reminder that the Oki Data test is applied contextually, not mechanically.

Domain investors and portfolio evidence

A professional domain investor can have a legitimate interest in a domain, but the defence is not automatic. Panels recognise that the business of acquiring and reselling domain names is a bona fide commercial activity under the UDRP, and that a domain acquired as part of an established portfolio business, not to target a trademark holder, can support a legitimate interest.

The legitimate investor profile typically includes:

• A larger portfolio of domains.
• Registration through specialised entities.
• A documentable history of domain transactions.
• Active offering of the domain for sale at market price.
• A credible rationale for the choice of the domain that does not rely on the trademark owner’s goodwill.

In D2024-4776, the panel considered a professional domain investor who offered the domain for sale through GoDaddy’s brokerage service at USD 48,500. The panel noted that the asking price exceeded out-of-pocket costs, but also that the practice of registering a domain for subsequent resale does not in itself support a bad-faith finding. The complainant had not presented adequate evidence that the respondent registered the domain primarily for the purpose of transferring it specifically to the complainant or a competitor.

The investor defence is stronger where the domain has a generic or descriptive meaning that justifies the registration independent of the mark. In HCL.ai, the respondent argued that “HCL” is a common three-letter acronym, but the panel found the respondent had no credible rationale for the choice beyond the trademark value, given the pairing with .ai and the respondent’s sophistication.

The investor defence is weaker where:

• The portfolio contains multiple domains matching third-party marks.
• The respondent targeted the complainant with an offer to sell.
• The domain has no generic or descriptive meaning independent of the mark.
• The respondent failed to check whether the domain matched a trademark.

The “stepping into the shoes” problem is a further complication. Where a portfolio is acquired, the question arises whether the acquisition preserves the original registration date for bad-faith purposes. Panels have treated this carefully, and the answer depends on the evidence of the portfolio transfer and the respondent’s knowledge at the time of acquisition.

Dictionary and generic words

A domain comprised of a dictionary word or phrase is not automatically protected. WIPO Overview 3.0, section 2.2 states that if the complainant makes a prima facie case and the respondent fails to show a paragraph 4(c) circumstance, the respondent may lack a legitimate interest even if the domain is a dictionary word.

The factors panels look for include:

• The status and fame of the trademark.
• Whether the respondent has registered other dictionary-word domains.
• Whether the domain is used in connection with a purpose relating to its generic or descriptive meaning.

The classic example is “apple”: a respondent may have a right to apple.com if it uses it for a genuine site about the fruit, but not if the site sells computers or MP3 players. The domain must be genuinely used or demonstrably intended for use in connection with the relied-upon meaning, not to trade off third-party rights.

Paragraph 4(c)(ii): Commonly known by the domain name

Paragraph 4(c)(ii) provides that a respondent has rights or legitimate interests if:

“[the respondent] (as an individual, business, or other organization) has been commonly known by the [disputed] domain name, even if [the respondent] has acquired no trademark or service mark rights”.

What “commonly known” requires

The respondent must show that it has been commonly known by the domain name. This is not the same as owning a trademark. It is about recognition — by customers, suppliers, the trade, or the public.

The evidence can include:

• Business registration or a trading name matching the domain.
• Invoices, letterhead, and contracts using the name.
• Social media profiles and press coverage.
• Customer or supplier statements.
• Directory listings and industry memberships.

The claim is stronger where the name has been used over time and in trade. A business that registered the domain yesterday and put up a holding page is not “commonly known” by the name.

Business registration, trading names, and letterhead

A registered business name is strong evidence, but it is not conclusive. Panels look at whether the name is actually used in trade, not just registered. A business that registered the name but trades under a different brand is weaker than one that uses the name on invoices, contracts, and correspondence.

The strongest evidence combines:

• A business registration or trading name.
• Invoices and contracts using the name.
• Advertising and marketing under the name.
• Customer correspondence addressed to the name.

Personal names, surnames, and nicknames

A respondent who is commonly known by a personal name that matches the domain can satisfy paragraph 4(c)(ii). The classic example is a respondent whose surname matches the domain. In the speroni.com decision, the respondent’s surname was Speroni, and a Wayback capture from 1997 showed the domain resolving to the respondent’s contact details. The panel found RDNH because the complainant had been wilfully blind to publicly available evidence.

The personal-name defence is stronger where:

• The name is the respondent’s actual surname or given name.
• The respondent has used the name personally or professionally.
• There is no evidence of targeting the complainant.

It is weaker where:

• The name was adopted after the dispute arose.
• The respondent has no genuine connection to the name.
• The name is primarily known as the complainant’s mark.

What weakens a “commonly known” claim

A “commonly known” claim is weakened by:

• Recent adoption of the name, after notice of the dispute.
• No use in trade — a holding page or a parked domain.
• No business registration or trading name.
• Inconsistency between the domain and the respondent’s actual trading name.
• Evidence of targeting the complainant.

Panels are sceptical of claims that are self-serving and unsupported by documents. A respondent who says “I have been known by this name for years” without invoices, contracts, or press coverage has not discharged the burden.

Paragraph 4(c)(iii): Legitimate noncommercial or fair use

Paragraph 4(c)(iii) provides that a respondent has rights or legitimate interests if:

“[the respondent] is making a legitimate noncommercial or fair use of the [disputed] domain name, without intent for commercial gain to misleadingly divert consumers or to tarnish the trademark or service mark at issue”.

Criticism sites and the genuineness test

The most litigated application of paragraph 4(c)(iii) is the criticism site. UDRP jurisprudence recognises that the use of a domain name for fair use such as noncommercial free speech can support a legitimate interest.

The test is genuineness. WIPO Overview 3.0, section 2.6.1 states that to support fair use, the respondent’s criticism must be genuine (i.e., not pretextual). Panels do not look at the veracity or accuracy of the criticism, nor at whether it is defamatory. They look at whether the motivation behind the criticism is genuine, as opposed to a sham or pretext to hide another motive such as cybersquatting or commercial activity.

The factors panels weigh include:

• Whether the site is active and contains genuine criticism.
• Whether the site is noncommercial — no advertising, no affiliate links, no competing service.
• Whether the site is clearly distinct from the complainant’s official site.
• Whether the domain is identical to the trademark or includes a derogatory term.

Fan sites and informational sites

Fan sites and informational sites are treated similarly. WIPO Overview 3.0, section 2.7.1 states that a respondent’s fan or informational site must be active, genuinely noncommercial, and clearly distinct from any official complainant site.

A fan site that is commercial — selling merchandise, running ads, or linking to affiliates — is weaker. A fan site that mimics the official site is weaker still, because it creates a risk of confusion.

The “trademarksucks” line of cases

Where the domain is not identical to the trademark but comprises the mark plus a derogatory term — for example, trademarksucks.tld — panels tend to find that the respondent has a legitimate interest in using the mark as part of the domain name of a genuine criticism site, provided the use is prima facie genuinely fair and not misleading or false.

Some panels have found that a degree of commercial activity may be permissible in such cases — for example, as “fundraising” to offset registration or hosting costs. But the commercial activity must not become the primary purpose of the site.

Where the domain is identical to the trademark — trademark.tld — panels are less willing to find a legitimate interest, even where the site is used for genuine noncommercial criticism. WIPO Overview 3.0, section 2.6.2 states that panels tend to find that an identical domain creates an impermissible risk of user confusion through impersonation.

Where fair use ends and tarnishment begins

Fair use ends where the use:

• Tarnishes the mark.
• Misleads consumers about source or affiliation.
• Is primarily commercial.
• Is pretextual — criticism used as a cover for cybersquatting or commercial gain.

A site that mixes genuine criticism with affiliate links to the complainant’s competitors is at risk. A site that impersonates the complainant while criticising it is at risk. A site that is purely a shill for a competitor is at risk.

Pretext and commercial gain

The panel’s inquiry is into motive. A respondent who claims to be a critic but whose site is monetised through advertising, affiliate links, or a competing service is unlikely to satisfy paragraph 4(c)(iii). A respondent who runs a genuine, noncommercial criticism site, with no advertising and no competing service, is in a much stronger position.

The consumer-complaint site case study is instructive. The registrant operated a site for over a year, publishing user reviews and editorial commentary, with no advertising and no competing service. The response built a chronological content record, documented the absence of monetisation, and raised RDNH. The case illustrates that a genuine criticism site with no commercial motive can defeat a complaint.

The Oki Data test in detail

The four cumulative requirements

The Oki Data test is the leading statement of the reseller/distributor defence. The four conditions are:

1. Actually offering the goods or services at issue.
2. Selling only the trademarked goods or services on the site.
3. Accurately and prominently disclosing the relationship with the trademark holder.
4. Not cornering the market in domain names that reflect the trademark.

The conditions are cumulative. A respondent who fails any one of them does not satisfy the test.

The “Lost Mary” reinterpretation

The Lost Mary decision in 2025–2026 revisited the Oki Data criteria. The Czech Arbitration Court panel suggested that a disclaimer is not always necessary, provided the reseller’s website is clearly distinguishable from the trademark owner’s website. The decision is a reminder that the Oki Data test is applied contextually, not mechanically. Panels look at the overall impression, not just the presence or absence of a disclaimer.

The disclaimer question

The third Oki Data condition requires the site to accurately and prominently disclose the respondent’s relationship with the trademark holder. A disclaimer that says “we are an authorised reseller” is different from one that says “we are not affiliated with the trademark owner”. The first can be false; the second is protective.

The safest approach is a clear, prominent disclaimer that the site is an independent reseller and is not the official site. The disclaimer should be on the homepage and on any page where products are sold.

Cornering the market

The fourth condition asks whether the respondent is trying to corner the market in domain names that reflect the trademark. A respondent who owns multiple domains matching the same mark, or who has a pattern of registering reseller domains across an industry, is at risk.

A single reseller domain, used for a genuine reseller business, is unlikely to be “cornering the market”. A portfolio of dozens of reseller domains, each matching a different brand, is a different picture.

Domain investors: when a portfolio is a business and when it is evidence

The legitimate investor profile

A legitimate domain investor typically:

• Holds a larger portfolio of domains.
• Registers through specialised entities.
• Has a documentable history of domain transactions.
• Offers domains for sale at market price.
• Has a credible rationale for each domain that does not depend on a third party’s trademark.

The profile is not a safe harbour. It is a framework for evidence. The investor must show that the domain was acquired as part of a genuine business, not to target the complainant.

The “stepping into the shoes” problem

Where a portfolio is acquired, the question arises whether the acquisition preserves the original registration date for bad-faith purposes. Panels have treated this carefully. The answer depends on:

• The terms of the portfolio transfer.
• The respondent’s knowledge at the time of acquisition.
• Whether the acquisition was genuine or a sham to obscure the original registrant.

A respondent who acquires a portfolio without checking whether it contains third-party marks may be wilfully blind. A respondent who acquires a portfolio with documented due diligence is in a stronger position.

Portfolio patterns that support bad faith

A portfolio can be evidence against the respondent. Patterns that support bad faith include:

• Multiple domains matching third-party marks.
• Prior adverse UDRP decisions against the respondent.
• A pattern of registering domains shortly after a trademark is announced.
• A pattern of offering domains for sale to trademark holders at inflated prices.
• A pattern of typosquatting.

The complainant can use these patterns to rebut the investor defence. The respondent must be ready to explain them.

What an investor must document

An investor defending a UDRP complaint should document:

• The acquisition history of the domain.
• The rationale for the choice of the domain.
• The portfolio context — how the domain fits the portfolio.
• The market price and the basis for it.
• Any prior negotiations or offers.
• The absence of targeting — no knowledge of the complainant at the time of acquisition.

The documentation should be contemporaneous where possible. After-the-fact reconstructions are less persuasive.

Evidence that persuades panels — and evidence that fails

Contemporaneous commercial records

The strongest evidence is created at the time, not reconstructed for the dispute. Invoices, contracts, purchase orders, bank records, advertising, and customer correspondence carry more weight than a witness statement written after the complaint arrived.

Website captures and Wayback

Dated screenshots with the URL bar visible are more persuasive than cropped images. Wayback Machine captures show how the domain was used before notice. Panels routinely consult the Wayback Machine to ascertain archived uses.

Witness statements

Witness statements are admissible but not required. Their weight depends on specificity, corroboration, timing, and credibility. A specific, corroborated statement is stronger than a general assertion. A notarised statement can strengthen credibility where the facts are contested.

Self-serving assertions

Claims that are merely self-serving and unsupported by pre-complaint evidence are discounted. In D2018-0657, the respondent’s sole argument — an intention to start a technical support consulting business — was found insufficient because it was not supported by relevant pre-complaint evidence.

After-the-fact reconstructions

A narrative written after the complaint arrived is less persuasive than contemporaneous documents. Panels are alert to after-the-fact explanations that are not supported by the record.

Provider-specific evidence rules

WIPO

WIPO applies the UDRP Rules and its Supplemental Rules. The word limit for the response is 5,000 words for the portion responding specifically to the complaint. Annexes are not counted. File limits are typically 10MB per attachment and 50MB total. WIPO’s Model Response provides a structure, but it should be adapted to the facts.

Forum

Forum applies the UDRP Rules and its own Supplemental Rules. The response deadline is 20 days from commencement. Forum’s filing and evidence requirements are similar to WIPO’s, with its own electronic filing system.

ADNDRC

ADNDRC applies the UDRP Rules and its Supplemental Rules. It has offices in Beijing, Hong Kong, Kuala Lumpur, and Seoul, and may be preferable where the respondent or the evidence is in Asia.

CAC

CAC applies the UDRP Rules and its Supplemental Rules. Its fee structure includes a supplement if there is a response or complexity. CAC’s online platform handles filing and evidence submission.

CIIDRC

CIIDRC applies the UDRP Rules and its Supplemental Rules. It is a newer provider and may offer more personalised case management.

Worked hypotheticals

The former developer

Facts: A developer built a website for the complainant in 2019 and registered the domain in their own name. The relationship ended in 2022. The developer kept the domain and used it for a personal portfolio. The complainant filed a UDRP in 2026.

Analysis: The developer has a paragraph 4(c)(i) argument if the domain was used for a genuine portfolio business before notice. But the registration in the developer’s own name, while building a site for the complainant, may support a finding that the developer knew of the complainant’s mark and registered in bad faith. The strength of the defence depends on the written agreement between the parties and the use of the domain after the relationship ended.

Lesson: The timing of registration and the reason for holding the domain are critical. A developer who registered the domain for the client but held it personally may struggle to show a bona fide offering.

The reseller

Facts: A respondent sells the complainant’s products through a domain that includes the complainant’s mark. The site sells only the complainant’s products, includes a disclaimer that it is an independent reseller, and has been operating for three years.

Analysis: The respondent can rely on Oki Data. The four conditions are likely satisfied: the respondent is actually offering the goods, sells only the trademarked goods, discloses the relationship, and is not cornering the market. The defence is strong, provided the evidence is contemporaneous and the disclaimer is prominent.

Lesson: The Oki Data conditions are cumulative, and the evidence must address each one.

The critic

Facts: A respondent operates a site criticising the complainant’s business practices. The domain is [complainant]sucks.com. The site has no advertising, no affiliate links, and no competing service. It has been active for two years.

Analysis: The respondent can rely on paragraph 4(c)(iii). The criticism is genuine, noncommercial, and not pretextual. The domain is not identical to the mark — it includes a derogatory term — which supports the fair-use finding. The defence is strong.

Lesson: The genuineness of the criticism and the absence of commercial motive are decisive.

The investor

Facts: A professional domain investor acquired the domain at auction in 2020. The domain is a common English word. The investor has a portfolio of 500 domains, a documented transaction history, and offers domains for sale at market prices. The complainant’s mark was registered in 2023.

Analysis: The investor has a strong paragraph 4(c)(i) argument. The domain was acquired before the complainant’s mark arose, it has a generic meaning, and the investor has a documented business. The complainant will struggle to show bad-faith registration.

Lesson: Priority and a documented investor profile are powerful defences.

The dictionary-word owner

Facts: A respondent registered a domain that is a common dictionary word. The respondent uses it for a genuine site about the word’s ordinary meaning. The complainant has a trademark in the same word for unrelated goods.

Analysis: The respondent can rely on paragraph 4(c)(i) and the dictionary-word principle. The domain is used in connection with its generic or descriptive meaning, not to trade off the complainant’s mark. The defence is strong if the use is genuine and not a pretext.

Lesson: The use must be tied to the ordinary meaning of the word, not to the trademark value.

When legitimate interest is not enough

The conjunctive test

The UDRP requires the complainant to prove all three elements. A respondent who establishes a legitimate interest defeats the second element, and the complaint fails. But a respondent who fails to establish a legitimate interest can still win if the complainant cannot prove bad faith.

The converse is also true: a respondent who establishes a legitimate interest may still lose if the complainant proves bad faith and the panel finds the legitimate interest is not genuine. The elements are separate, but they interact.

Bad-faith use after a good-faith registration

Under the UDRP’s conjunctive test, bad-faith use cannot turn a good-faith registration into a bad-faith one. The consensus view is that the original registration or subsequent acquisition must have been in bad faith.

This is a critical limit on the complainant’s case. A respondent who registered the domain in good faith, and later used it in bad faith, may still defeat the third element. The auDRP, Nominet DRS, CNDRP, INDRP, and usDRP use a disjunctive test, which is more favourable to complainants in later-use cases.

The “retroactive bad faith” problem

Some panels explored a theory of “retroactive” bad faith registration, based on the registrant’s representations in paragraph 2 of the UDRP. The theory has not been followed in subsequent cases. WIPO Overview 3.0, section 3.2.1 notes that the concept has not been followed, though paragraph 2 may be relevant on its own terms.

The practical lesson is that the registration date is critical. A respondent who registered before the mark arose is in a strong position under the UDRP, even if later use was aggressive.

The 20-day legitimate-interest checklist

• Identify the date of commencement and the response deadline.
• Assess the complainant’s prima facie case: What evidence has it produced? Is it enough to shift the burden?
• Identify the safe harbour: 4(c)(i), 4(c)(ii), or 4(c)(iii).
• Preserve evidence immediately: invoices, contracts, advertising, bank records, correspondence, website captures.
• Check the timing: Does the use predate notice of the dispute?
• Assess “bona fide”: Is the use genuine, or does it trade on the mark?
• For resellers: Apply the four Oki Data conditions.
• For investors: Document the portfolio, the acquisition history, and the rationale.
• For critics: Document the genuineness and noncommercial nature of the criticism.
• Build the annex schedule: Numbered, indexed, dated.
• Consider RDNH: Is the complaint abusive?
• File on time.

How counsel.domains can help

If you have received a complaint, we review the deadline, test the complainant’s prima facie case, and identify the strongest paragraph 4(c) defence.

If you have a genuine business, we build the evidence file — invoices, contracts, advertising, and the pre-notice timeline.

If you are a reseller, investor, or critic, we apply the Oki Data test, document the portfolio, or build the noncommercial record.

If the complaint is abusive, we assess whether an RDNH counterclaim is viable.
