Methodology
UDRP figures come from Westmore's copy of 102,739 published WIPO, Forum and CAC decisions; a case counts as a complainant win when the panel ordered transfer or cancellation, and as a loss when the complaint was denied or found to be reverse domain name hijacking. Split and other outcomes are excluded. Funded-company figures cover venture-funded companies with a verified live website (public filings without a reliable website are excluded); "not on the exact-match .com" means the live site is on another extension or a modified .com name. Figures are generated automatically from live data on the first of each month.
