Reverse domain hijacking
When a trademark holder files a UDRP complaint in bad faith — knowing their case has no merit — to extract a domain from a legitimate registrant. Sanctionable by the panel.
How panels respond
The panel can declare RDNH in the decision text, putting the complainant on record as having abused the process. Some legitimate trademark holders have lost UDRP credibility this way.
Defense
Generics, prior registration evidence, and non-competing use are the standard defenses against an RDNH-inviting complaint.
