.XXX Domain Names - Get 'em while they're hot
"While traditional rights protection mechanisms, such as the Uniform Domain Name Dispute Resolution Policy (UDRP), will apply to .xxx domain names, and while ICM Registry has implemented a host of other protection mechanisms that will aid trademark owners seeking to combat infringing - or simply disparaging - use of valuable brands, trademark owners should consider 'pre-reserving' and/or defensively registering key .xxx domain names containing valuable trademarks."
