Description

country

 

The country is represented by a standard 2-character code based on WIPO ST.3. In the case of WO publications, the country is the authority where the application was filed.

doc-number

21

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 number in DOCDB format has changed since late 2010 (beginning of series code 13) (See link below for more details.) USPTO "original" format always includes 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. 131699or 2007000849).
