Element	INID	Description
country	-	Country is represented by a standard 2-character code based on WIPO ST.3.
doc-number	-	`doc-number` is provided in both DOCDB-normalized format and in the format provided by the publishing patent office. DOCDB-normalized format usually includes the filing year (2 or 4 digits) at the beginning or end unless the year is already embedded in the application number. US application numbers in DOCDB format have changed since late 2010 (beginning of series code 13, see link below for more details). USPTO "original" format always includes a prepended series code. WO application numbers are formatted with a 2-digit year followed by a 5-digit serial number prior to 2004-01-01. Beginning with application dates in 2004, the format is 4-digit year followed by 6-digit serial number (e.g. 9813495 or 2004000001). A kind code of "W" must be used to distinguish WO applications from national office applications. JP application numbers include a 2-digit year as suffix until 2000; thereafter the 4-digit year is prepended (e.g. 131699 or 2007000849). For a complete discussion of application numbers in DOCDB over time and over multiple authorities, see Number format concordance - application numbers at https://www.epo.org/searching-for-patents/helpful-resources/data/tables/regular.html.
kind	-	Kind code of applications comes from DOCDB or is inferred according to DOCDB rules. Values include: A=Patent U=Utility P=Provisional application W=PCT F=Design T=Translation
date	-	Date of filing of application (YYYYMMDD).
