Just like as - "US Patent 6701329 - Aging and scavenging of DNS resource records" (Microsoft) - "US Patent 7337910 - Methods and devices for responding to request for unregistered domain name to indicate a predefined type of service" (Verisign SiteFinder fiasco) - "US Patent 6560634 - Method of determining unavailability of an internet domain name" (Verisign) - "US Patent 7580982 - Email filtering system and method" (Go Daddy) - "US Patent 7130878 - Systems and methods for domain name registration by proxy" (Go Daddy) Just to list a few. Be careful the next time you use "vi", somebody may have already patented that regular expression. Cheers Jorge
