priority-claims/priority-claim

Attribute

Description

ucid, mxw-id, load-source

See Common XML Attributes. 
Note: If on the child document-id, the attribute format="original" has been added, the ucid attribute is not required.

linkage-typeAn indicator of priority relation, this single character identifies priorities as division, continuation, or addition patents. See ANNEXX III of the DOCDB manual for a full listing of linkage types.

priority-claims/priority-claim/document-id

Attribute

Description

format

Designates the normalized or not-normalized format of the following document-id. 
epo=standardized DOCDB format 
original=unparsed format directly from the data source 
Both "original" and "epo" formats are provided if available.

Element

INID

Description

country

33

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

31

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).

P=Provisional application
