Case study: defend a .jp domain registered before the complainant's trademark
A registrant holds a .jp domain for several years. Then a company files a trademark – one that postdates the domain's registration – and promptly sends a cease-and-desist demanding transfer. The registrant did nothing wrong. Yet the complaint arrives anyway.
Where the domain was registered before the complainant's trademark rights existed, the third UDRP element – or its equivalent under the JP-DRP, Japan's country-code dispute-resolution policy – cannot logically be satisfied on the bad-faith-at-registration limb. Prior registration is a powerful, often decisive defense. The realistic next step is documenting that timeline precisely and building the full legitimate-interest record before the panel reads a single page of the complaint.
This case study walks the situation, the strategy we applied, and the outcome.
The Situation: a .jp domain targeted after the fact
The registrant – a small technology services company based in Japan – had registered a two-word .jp domain in the mid-2010s for a software project. The name was descriptive of the project's function, not coined. No trademark application was filed at the time; none was needed for the intended use.
Years later, a foreign brand owner entered the Japanese market with a product line under the same two-word phrase. It registered a trademark in Japan, then filed a JP-DRP complaint alleging confusing similarity, no legitimate interest, and bad-faith registration and use. The filing came approximately eighteen months after the trademark issued – and roughly four years after the domain was registered.
The registrant received the complaint notice and contacted us. The four-year registration gap was immediately apparent. So was the complainant's commercial motive: the demand letter that preceded the complaint cited the domain's "brand value" and offered a nominal sum well below market – a buy-low pressure play dressed as a good-faith offer.
The Strategy: timeline, safe harbors, and the RDNH argument
The JP-DRP tracks the UDRP closely in its three-element structure. The bad-faith requirement applies to registration and use. A registrant who held the domain before the complainant's trademark came into existence cannot, as a logical matter, have registered it in bad faith targeting rights that did not yet exist. That single chronological fact was the foundation of the entire defense.
We built the record in three layers.
Layer one: the registration timeline. We obtained archived WHOIS records, the original registrar confirmation, and the historical DNS data showing the domain had been pointed at a live project page continuously since registration. The four-year gap between domain creation and trademark filing was documented with primary sources, not assertions.
Layer two: legitimate interest under the Paragraph 4(c) safe harbors. The registrant had used the domain in connection with a genuine, ongoing software offering before any notice of the dispute. That squarely meets the bona fide use safe harbor. We prepared a factual exhibit – internal development records, dated code repository commits, and archived product pages – showing continuous commercial use. The name was descriptive; dozens of third-party pages used the same phrase in the same technical context. None of that evidence required our client to prove a registered trademark. The safe harbor does not demand one.
Layer three: the RDNH argument. When a complainant files knowing – or with constructive knowledge – that the domain predates its rights, that filing meets the standard for a Reverse Domain Name Hijacking finding. RDNH under the JP-DRP, like its UDRP counterpart, carries no monetary penalty. But it is a public finding of bad faith by the complainant. We argued the complainant's own trademark filing date was in the public record; counsel of any competence would have found the registration gap in basic due diligence. Filing regardless was an attempt to use the dispute procedure to extract a transfer the complainant could not obtain on the merits.
We regularly advise registrants who face complaints filed despite clear pre-registration ownership. If you hold a domain and have received a JP-DRP or UDRP complaint, contact info@cognomenlaw.com to assess the three elements and the realistic defense timeline before your response deadline passes.
The Outcome: complaint denied, RDNH finding entered
The panel denied the complaint in full. On the third element, the decision turned precisely on the chronology: registration predated trademark rights, and no independent evidence of bad faith at registration was presented by the complainant. The legitimate-interest finding followed directly from the continuous, documented use record.
The RDNH finding was entered. The panel noted that the complainant or its counsel had access to the registration date through public WHOIS data. Filing a complaint with no realistic prospect of satisfying the bad-faith element – in circumstances where a competent pre-filing search would have revealed the date gap – supported the conclusion that the complaint was brought to attempt a transfer the Policy does not permit.
The registrant retained the domain. No transfer, no cancellation. The buy-low pressure tactic failed entirely.
In a comparable matter from the same period – a .jp domain in the consumer-electronics sector, autumn 2025 – we secured an identical outcome for a registrant who had held a descriptive domain for over six years before the complainant's brand entered the Japanese market. The complainant withdrew its monetary offer once we filed the response with the full chronological exhibit. The panel still entered an RDNH finding on the uncontested record.

Frequently asked questions
Does registering a domain before a trademark always defeat a UDRP or JP-DRP complaint?
Prior registration is a strong defense because bad faith at registration cannot logically arise where no trademark rights existed at the time. It is not automatically decisive, however. A panel will examine whether the registrant independently targeted a well-known unregistered mark or acted in anticipation of the complainant's rights. Where the name is genuinely descriptive and used continuously, that argument is extremely difficult for a complainant to sustain.
What is an RDNH finding and what does it actually do?
A Reverse Domain Name Hijacking finding is a panel's determination that the complaint was brought in bad faith – typically to strip a legitimate registrant of a domain the complainant could not win on the merits. Under both the UDRP and the JP-DRP the finding carries no monetary penalty. It is a public statement on record. For complainants with reputational concerns or repeat-filing patterns, that public finding has real-world weight.
How quickly must a registrant respond to a JP-DRP complaint?
The JP-DRP response period is governed by the applicable procedural rules of the designated provider. As with the UDRP, the response window is limited – typically on the order of 20 days from commencement of the proceeding. Missing the deadline means the panel proceeds on the complaint alone. Retaining counsel as soon as the complaint notice arrives is strongly advisable.
