Reverse Domain Hijacking (RDNH)

Abusing the UDRP in bad faith to try to seize a domain from its legitimate owner.

Reverse domain hijacking (RDNH) is a declaration by a UDRP panel that the complainant brought its case in bad faith, in an attempt to deprive a legitimate domain owner of their registration rather than to remedy genuine trademark abuse. A panel will make an RDNH finding when the complainant knew or should have known it could not satisfy one of the three required UDRP elements — for example, when the registrant demonstrably registered the domain before the trademark existed, or where the complainant's mark is descriptive and the domain has an obvious generic meaning. RDNH is a reputational sanction only; the UDRP provides no monetary penalties against complainants, though a pattern of abusive filings can inform future panels. Well-resourced brands have been found to engage in RDNH when they covet a short, valuable domain and file a weak case hoping the registrant will default. Because domain hijacking is a separate concept involving unauthorized account takeover, the "reverse" in RDNH specifically signals that it is the complainant, not the registrant, acting improperly. Domain owners whose tokenized assets are targeted by a UDRP complaint should seek specialist counsel promptly — the default rate in UDRP proceedings is high, and a missed deadline results in transfer.
