Udemy, Inc. successfully secured the transfer of the disputed domain <udemy.blog> under the UDRP framework. The Respondent, Hiroki Ogawa, registered the brand-identical domain in bad faith but left it inactive. WIPO Panelist Haig Oghigian ruled that the passive holding of this distinctive trademark constituted bad faith and ordered the domain transferred to the Complainant.

Latent Fraud Vectors and Corporate Communication Vulnerabilities
The passive holding of the brand-identical domain <udemy.blog> presents a severe, latent risk of customer deception, phishing, and invoice fraud. Although the case file contains no evidence of active phishing campaigns, fake invoices, or customer data theft, the structural risk of the domain remains high. If the Respondent, Hiroki Ogawa, or a subsequent holder were to activate Mail Exchanger (MX) records on this domain, it could easily be used to launch targeted email fraud campaigns. Because the domain perfectly replicates the ‘UDEMY’ mark, spoofed emails sent to Udemy’s pool of over 81 million registered users, students, or instructors would carry a high degree of perceived authenticity. This could lead to unauthorized credential harvesting or fraudulent billing requests, exploiting the trust built around Udemy’s global brand.
The choice of the ‘.blog’ generic top-level domain introduces additional commercial and reputational threats. Even though the Respondent did not deploy a fake shop or clone Udemy’s active online course directory, the unauthorized domain naturally suggests an official public relations, updates, or educational resource center. This creates an immediate risk of traffic diversion, where prospective corporate partners and learners seeking official corporate communications could be misled. If an unauthorized entity were to populate the site with misleading content, it would dilute Udemy’s official marketing channels and could easily redirect valuable web traffic toward malicious destinations or unauthorized alternative service providers.
Furthermore, the Respondent’s use of a privacy service, onamae.com, to mask their true identity during registration signals a deliberate attempt to evade direct accountability. Brand protection professionals recognize that passive holding coupled with identity masking is a common strategy to keep a domain dormant until a strategic moment. While the Complainant did not present proof of actual financial losses or specific victim stories in this case, the proactive recovery of <udemy.blog> represents a crucial defensive action. Securing the domain before it can be weaponized protects corporate communication infrastructure and prevents consumer fraud before any actual damage can materialize.
Panel Evaluation of Confusing Similarity, Rights, and Bad Faith in Passive Domain Holding
In assessing the first element of the UDRP, the Panelist Haig Oghigian analyzed the structural identity between Udemy, Inc.’s registered trademark and the disputed domain name <udemy.blog>. The Complainant established its rights through numerous global trademark registrations, including those in the United States, the European Union, and Australia, dating back to 2012 and 2013. The disputed domain name incorporates the ‘UDEMY’ mark in its entirety. The Panel followed established UDRP precedent by disregarding the generic top-level domain (gTLD) ‘.blog’ as a functional technical requirement, which does nothing to mitigate the confusing similarity created by the prominent reproduction of the distinctive brand.
Regarding the second element, the legal reasoning focused on the complete absence of any rights or legitimate interests on the part of the Respondent, Hiroki Ogawa. The Respondent is not commonly known by the name ‘udemy,’ possesses no trademark rights incorporating that term, and received no license, authorization, or business relationship from the Complainant. Furthermore, because the domain name did not resolve to an active website, the Respondent failed to demonstrate any preparation for a bona fide offering of goods or services, or any legitimate noncommercial or fair use. This passive setup confirms that the selection of the domain name was purely speculative, aimed at exploiting a highly distinctive corporate identifier.
Under the third UDRP element, the bad faith analysis centered on the distinctiveness of the trademark and the doctrine of passive holding. The ‘UDEMY’ mark has no generic or common usage in any language, making it highly improbable that the Respondent registered the domain without prior knowledge of the Complainant. Given that Udemy’s trademark registrations predate the domain’s registration date of October 19, 2025, by more than twelve years, a simple online search would have immediately alerted the Respondent to the Complainant’s existence. Consequently, the Panel determined that the passive holding of this brand-identical domain, coupled with the Respondent’s use of a privacy service (onamae.com) to mask their identity, established bad faith registration and use under the totality of the circumstances.
For brand protection professionals, this ruling highlights the utility of the UDRP in neutralizing dormant threat vectors before active damage occurs. Although this case lacked evidence of active phishing, fake invoice fraud, or a cloned website, the registration of a brand-identical domain under an authoritative gTLD like ‘.blog’ creates severe exposure. If the domain had remained under the Respondent’s control, the potential activation of mail exchange (MX) records could have facilitated highly convincing email-based fraud targeting Udemy’s 81 million learners and instructors. This decision confirms that brand owners do not need to wait for actual deception, monetary loss, or victim stories to materialize before taking decisive legal action to secure their digital perimeter.
Strategic Procedural Maneuvers and the Power of Mark Distinctiveness
Udemy’s legal strategy succeeded by effectively navigating cross-border procedural hurdles and utilizing WIPO guidelines to neutralize language barriers. Despite the registration agreement being in Japanese and the Respondent, Hiroki Ogawa, residing in Japan, Udemy proactively requested English as the language of the proceeding. This tactical choice, confirmed on December 3, 2025, forced the Respondent to either defend the case in English or contest the language choice. The Respondent’s failure to respond led to a default, allowing the administrative process to proceed efficiently without the Complainant incurring extensive translation expenses or prolonged delays.
Substantively, the Complainant overcame the challenge of passive holding by demonstrating the absolute distinctiveness of the ‘UDEMY’ trademark, which has no generic or common usage. By presenting trademark registrations in the United States, European Union, and Australia dating back to 2012 and 2013, Udemy established a twelve-year priority timeline over the October 19, 2025 domain registration. Panelist Haig Oghigian accepted that the passive holding of such a highly distinctive trademark, combined with the Respondent’s use of a privacy shield (onamae.com), supported a finding of bad faith registration and use, even in the absence of active phishing campaigns, fake stores, or documented financial losses.
Practical Recommendations
- Implement automated domain-monitoring alerts for highly distinctive corporate brand names across newly released and popular gTLDs (such as ‘.blog’, ‘.app’, and ‘.support’) to detect and neutralize exact-match registrations before they are utilized in active campaigns.
- Proactively monitor newly registered, inactive brand-identical domains for the activation of Mail Exchange (MX) records to preemptively mitigate the risk of targeted phishing, invoice fraud, and corporate spoofing schemes targeting customers or partners.
- Develop a standard legal framework to request English as the language of the UDRP proceedings when disputing domains registered through overseas registrars (such as GMO Internet, Inc.), leveraging arguments around global trademark recognition and the cost-efficiency of bypassing translation.
- Establish a rapid-response workflow for filing amended UDRP complaints immediately after a registrar unmasks the underlying registrant details behind privacy shields (like onamae.com), avoiding procedural bottlenecks or delays in panel appointments.
- Leverage the WIPO passive holding doctrine when taking action against inactive domains by documenting the absolute distinctiveness of the trademark and the lack of any plausible, legitimate non-commercial use by the respondent.
Frequently Asked Questions (FAQ)
Why did the panel find that ‘udemy.blog’ was confusingly similar to Udemy’s trademark?
The WIPO panel determined that the domain <udemy.blog> is confusingly similar because it incorporates the ‘UDEMY’ trademark in its entirety. The addition of the generic top-level domain ‘.blog’ does not distinguish the domain from the Complainant’s well-established mark, which has been in use for over a decade.
How did the complainant prove bad faith when the domain was not actively being used?
Under the ‘passive holding’ doctrine, the panel found that the Respondent’s registration of a highly distinctive, non-generic trademark like ‘UDEMY’ constituted bad faith. Since the Respondent had no legitimate rights to the name and the trademark’s uniqueness implies intent for misuse, the lack of an active website did not prevent a finding of bad faith.
What business risks did this specific domain registration pose to Udemy, Inc.?
Although the site was inactive, the domain created a significant risk of future phishing or email fraud. If the Respondent had activated MX records on the brand-identical ‘udemy.blog’, they could have intercepted corporate communications or targeted Udemy’s 81 million users with fraudulent invoices and phishing schemes.
How was the language of the proceeding handled given the registrant’s location in Japan?
Although the registration agreement was in Japanese, the Complainant successfully requested that the proceedings be conducted in English. The Respondent failed to submit any comments or objections to this procedural shift, and the panel ultimately moved forward in English to resolve the dispute efficiently.
