Tinder LLC filed a UDRP complaint attempting to transfer the disputed domain kinkyswipe.com, arguing that it confusingly targets their registered SWIPE trademark. The WIPO Panel denied the complaint, finding that the Respondent has operated a legitimate, functionally distinct adult niche platform for over six years without bad faith intent. As a result, the domain remains with the Respondent, highlighting a critical portfolio gap for the Complainant.

Portfolio Gaps and the Commercial Risks of Legitimate Third-Party Registrations
The primary commercial threat highlighted by this dispute is the vulnerability brand owners face when relying on generic action words like SWIPE without establishing a comprehensive defensive registration strategy. By failing to proactively register adjacent brand-plus-keyword combinations, Tinder LLC allowed a third-party registrant, Maria Rousou of Karneolis LTD, to acquire and develop kinkyswipe.com in an adjacent market. Because the Respondent operated the website within a niche adult and fetish market for over six years, the Panel determined that she had established a legitimate commercial interest. This demonstrates that brand owners cannot rely on the UDRP to reclaim domain names that incorporate their marks if those domains are utilized for distinct, non-confusing commercial purposes outside the brand’s mainstream offerings.
Furthermore, this case outlines the reputational and trademark enforcement challenges that arise when defensive registration gaps are exploited. Although there is no evidence of actual customer confusion, malware, or phishing, the permanent association of the SWIPE brand element with an adult platform presents an ongoing portfolio concern that cannot be resolved via transfer. The Respondent’s independent efforts to secure registered trademark rights for ‘kinkyswipe’ with the EUIPO further complicate the brand’s enforcement landscape. For trademark professionals, this outcome highlights the necessity of early, proactive acquisitions of key keyword combinations across various TLDs, as reclaiming these domains post-development is highly difficult once legitimate third-party rights are established.
WIPO Panel Analysis: Standing Established but Legitimate Interest and Lack of Bad Faith Prevail
The WIPO Panel established that the first element of the UDRP is met because the disputed domain name, kinkyswipe.com, incorporates the Complainant’s registered SWIPE trademark in its entirety. Under the standing threshold of the Policy, the addition of the descriptive prefix "kinky" does not prevent a finding of confusing similarity. While the addition of other terms may bear heavily on the evaluation of rights, legitimate interests, and bad faith, it does not defeat the basic, objective comparison required to establish the Complainant’s standing under the first element.
However, the Complainant’s transfer request failed on the second element regarding rights or legitimate interests. The Panel found that the Respondent, Maria Rousou of Karneolis LTD, established a genuine commercial interest through over six years of active operation and user acquisition under the kinkyswipe.com domain. Since its registration in 2019, the Respondent actively invested in developing the platform, building a dedicated user base, and maintaining the underlying technology within a specialized adult and fetish market. The legitimacy of these operations was further supported by the Respondent’s efforts to acquire registered trademark rights for the term "kinkyswipe" with the EUIPO.
The Panel further determined that the domain was not registered or used in bad faith, pointing to the distinct functional characteristics of the Respondent’s platform. The website serves a niche "kinky/fetish" market catering to adult fantasies, which distinguishes it from Tinder’s mainstream romantic matchmaking platform. Because the website’s layout, targeting, and utility are highly differentiated, the Panel saw no intention to attract users through confusion. The complete lack of evidence showing actual confusion or security issues among Tinder’s customer base reinforced the conclusion that the Respondent operated without opportunistic intent.
For brand protection professionals, this case demonstrates the limitations of policing generic or descriptive action words like SWIPE when applied to third-party registrations in niche markets. When brand keywords are integrated into distinct, long-term commercial platforms operating outside mainstream offerings, UDRP panels are highly unlikely to find bad faith or lack of rights. This highlights a critical defensive registration gap, emphasizing that brand owners must proactively register core brand keywords across multiple combinations before legitimate third-party competitors secure them.
Analyzing the Threshold Success and Ultimate Failure of the Complainant’s Strategy
The Complainant’s initial legal strategy succeeded in establishing the first element of the UDRP criteria by relying on its registered EUIPO trademark for the term SWIPE. Under WIPO jurisprudence, the addition of descriptive or qualifying terms to a registered trademark does not prevent a finding of confusing similarity. The Panel agreed that adding the prefix "kinky" to the SWIPE mark maintained a core similarity, thereby satisfying the threshold standing requirement under the first element. This demonstrates that even common action words, when registered as trademarks, can successfully block unauthorized domain registrations on a purely technical comparison level.
However, the Complainant’s broader strategy failed because the Respondent presented highly persuasive evidence of legitimate commercial use and a lack of bad faith. Over a six-year period since registering the domain name in 2019, the Respondent actively operated a platform targeting a niche adult and fetish market, which the Panel found to be functionally distinct from Tinder’s mainstream dating services. Furthermore, the Respondent’s efforts to secure its own EUIPO trademark registration for "kinkyswipe" and its documented investments in user acquisition and technology established a legitimate business interest, demonstrating that long-term, non-confusing niche operations can successfully counter UDRP transfer claims.
Practical Recommendations
- Execute proactive defensive registrations for key trademark terms combined with industry-adjacent or high-risk niche descriptors (such as adult, fantasy, or dating terms for a relationship brand) to prevent third parties from occupying adjacent digital spaces.
- Establish active domain monitoring and intervene early in a domain’s lifecycle rather than waiting multiple years, as a respondent’s multi-year active operation and technology investment can establish a legitimate commercial interest that defeats UDRP complaints.
- Monitor global trademark registries (like the EUIPO) for third parties attempting to register brand-adjacent terms (such as ‘kinkyswipe’) and file timely oppositions to prevent them from building a defense of legitimate rights.
- Conduct thorough pre-complaint audits of target websites to assess if their functionality is distinct and catering to a highly differentiated niche market, as panels are unlikely to find bad faith if there is no evidence of consumer confusion or targeting.
- Utilize commercial acquisitions or private settlement strategies instead of UDRP filings when dealing with descriptive, generic, or common action-word trademarks (like ‘SWIPE’) that are actively used by legitimate, non-competing businesses.
Frequently Asked Questions (FAQ)
Why did the WIPO Panel find kinkyswipe.com confusingly similar to Tinder’s ‘SWIPE’ trademark?
The Panel determined that the first UDRP element is a standing requirement. It held that simply adding the descriptive term ‘kinky’ to the trademark ‘SWIPE’ does not eliminate the confusing similarity, meaning the domain name is still considered visually and conceptually similar to the Complainant’s mark.
What evidence proved that the Respondent had a legitimate interest in the domain?
The Panel found that the Respondent established legitimate rights by operating a niche, functionally distinct website for over six years. The Respondent’s long-term investment in developing a platform specific to the adult/fetish market, separate from Tinder’s conventional dating services, demonstrated a bona fide commercial interest.
Why was the bad faith claim against the Respondent rejected?
The Complainant failed to prove bad faith because the Respondent’s website provides a service that is distinct from Tinder’s offerings, with no evidence of an intent to cause consumer confusion. Furthermore, the longevity of the site’s operation without incident served to negate claims of opportunistic registration.
What business lesson should be taken from this UDRP loss?
This case highlights the risk of relying solely on UDRP actions to protect generic or action-oriented trademarks like ‘SWIPE’. When a third party creates a distinct, long-standing niche platform, UDRP panels are unlikely to order a transfer unless evidence shows clear bad faith or malicious intent to trade on the brand’s reputation.
Found a brand-plus-keyword impersonation domain?
Don’t wait for a UDRP panel to highlight gaps in your defensive strategy. Assess your exposure to brand-adjacent domain registrations before they become established, distinct commercial entities that are harder to recover.
