What happens if you lose a UDRP complaint
Losing a UDRP complaint means the domain stays exactly where it is and the panel awards nothing else. WIPO treats a second complaint on the same domain as exceptional, accepted under section 4.18 of the WIPO Overview only for narrow reasons such as new evidence or a breach of due process. Buying the domain or suing in court remain open.
Can I file the same complaint again?
Rarely. WIPO Overview 3.1, section 4.18, treats a re-filed complaint against the same domain, the same complainant and the same respondent as exceptional. Panels accept one only in narrow circumstances: legally relevant developments since the original decision, a breach of due process, newly discovered misconduct such as perjured evidence, genuinely new evidence that was not reasonably available the first time, or a prior decision that was expressly left open "without prejudice." A weak first complaint, filed again with better arguments, does not qualify.
Can I buy the domain instead?
Yes, and for most registrants who beat a UDRP complaint, being left alone is the outcome they wanted anyway. Once the case has run, you know exactly who the registrant is, since registrar verification discloses that as part of filing. Nothing in the UDRP stops you approaching them directly to negotiate a purchase. Expect to pay more than before the complaint, since you have shown your hand.
What about court?
Either side can take a UDRP decision to court instead of accepting it. After a decision, the registrar waits 10 business days from being notified before implementing it. File a lawsuit in a court of mutual jurisdiction (normally where the registrar or the registrant is based) within that window and send the registrar proof of the filing, and implementation pauses until the court rules. This is expensive relative to the UDRP itself, and worth it only where the domain's value or the point of law justifies full litigation.
What should I actually do?
Read the decision first. If it turned on weak evidence you can now supply, that is what section 4.18 exists for. If it turned on the domain predating your trademark rights, no new complaint will fix that, and a purchase approach or simply living with it are the realistic options.
