Subfields |

| ǂa Number | Patent document number, i.e., the number assigned by a competent authority (typically a patent office). The number is recorded according to Recording, Use, and Display of Patent Application Data (ANSI Z39.61). The number is recorded in a YY-AANNNNN pattern where YY represents the last two digits of the calendar year, AA represents letters (when required), and NNNNN represents the variable-length numeric portion of the application number. For application numbers containing the year or a part thereof as an integral part of the number, the last two digits of the year are taken from the application number itself. For application numbers that do not contain the year, the last two digits of the year are taken from the application date. For application numbers that use the Japanese year of the emperor, the year of the emperor is converted to the Gregorian calendar. An additional two positions may be added to record the complete calendar year where confusion may arise from omission of the century.
|
||||||||||||
| ǂb Country | Code representing the country or jurisdiction associated with the patent document. Code from MARC Code List for Countries. When an entity other than a country is associated with the patent document, the code is recorded in subfield ǂf. The country in which the patent document was published or produced is represented in coded form in Ctry. This is not always the country as coded in field 013 ǂb. If the same patent document number has been used in more than one country, field 013 must be repeated for each.
|
||||||||||||
| ǂc Type of number | Designation of the type of patent document identifier. The identifier is usually a number. Subfield ǂc may contain a term or a code identifying the type. The source of the code is Standard Code for Identification of Different Kinds of Patent Documents (WIPO ST.16) that is maintained by the World Intellectual Property Organization. The code is a one- or two-character code. Plain language terms are recorded as they appear on the item. Field 013 is repeated if there is more than one number to be recorded for an item.
|
||||||||||||
| ǂd Date | Date a patent or certificate was granted, or the date of acceptance of an application. The date requires 8 numeric characters in the pattern yyyymmdd (4 for the year, 2 for the month, and 2 for the day). Date is usually assigned by a competent authority (typically a patent office). The date of an application is typically the date of receipt by the agency. Other dates, such as effective dates, exhibitions dates, etc., are also recorded in this subfield. Multiple dates are recorded in separate occurrences of subfield ǂd if they all relate to the same patent document. Qualifying information is recorded in subfield ǂe. The date is recorded according to Data Elements and Interchange Formats-Information Interchange-Representation of Dates and Times (ISO 8601).
|
||||||||||||
| ǂe Status information | Text that explains or clarifies the status of the patent document identified by the number in the field. Status usually relates to the examination of an application or the granting/publishing of a patent.
|
||||||||||||
| ǂf Party to document | Information that identifies the country or agency that is party to the document, usually an application for patent or related document. Use codes from MARC Code List for Countries and MARC Code List for Organizations. When appropriate, subfield ǂf may contain a code identifying an organization (generally an international one).
