Mistral AI Reclaims Strategic lechat.chat Domain

UDRP Case

Key Case Facts

  • Case Number: D2025-5113
  • Contested Domain: lechat.chat
  • Verdict: Transfer Ordered

Mistral AI, a leader in the generative artificial intelligence sector, successfully challenged the registration of the domain lechat.chat held by Vladislav Zhelkovsky. In this UDRP proceeding, the company sought the transfer of the address, asserting that it was registered without authorization to mirror its “Le Chat” conversational platform. Mistral AI argued that the respondent sought to leverage the brand’s growing recognition in the tech industry to create a false association between the domain and the official AI assistant.

Rationale for the Transfer Order

The decision centered on the connection between the brand’s services and the registered domain. The reasoning established that:
I. The domain name directly incorporates the name of the AI service, and the choice of a category-specific extension further links the address to the specialized services provided by the company.
II. There was no demonstrable evidence of a previous business presence or a lawful reason for the respondent to use the name in a commercial context.
III. The registration occurred during a period of intense public interest in the brand, indicating that the domain was secured with the intent of targeting the company’s intellectual property.

Indicators of Deceptive Registration

The circumstances indicated that the domain was likely registered to profit from the reputation of the AI assistant. By picking a name identical to a prominent tech product, the respondent essentially blocked the brand from using a logical digital address while potentially siphoning traffic from unsuspecting users. This opportunistic registration reflects a clear intent to capitalize on a name to which the respondent had no prior connection.

Securing Product-Specific Touchpoints

For emerging tech companies, protecting product names is as vital as protecting the corporate brand itself. This case demonstrates that even when a brand name is composed of common words, it receives protection when it acquires distinctiveness through use in a specific market. Businesses should audit all potential “functional” domains—such as those ending in .chat, .ai, or .app—to prevent third parties from occupying these spaces. Early registration of these touchpoints is a critical component of a proactive intellectual property strategy.
