Number that the International Bureau of WIPO gives to a published international patent application under the Patent Cooperation Treaty. Since 2004 it is WO, the four-digit year of publication, a slash and a six-digit serial number, such as WO 2004/123456; data often uses a compact form with a kind code A1 to A4, A8 or A9. Older numbers have a two-digit year and a five- or six-digit serial number.
