Domain Name News notes that thanks to their 2001 acquisition of eNic Corporation (operator of the .CC registry), Verisign acquired a patent that covers systems like their much hated Sitefinder initiative, which redirected users who tried to access unregistered domain names to a parked, ad-laden page. While Verisign might sit on the patent (which was officially awarded on the 4th), they technically might be able to use it to get licensing fees from ISPs who have started using similar systems that turn subscriber typing mistakes into ad revenue.
