Codes for the classification of data

Key patent information is followed by a number. These numbers are called "INID codes".

(“INID” is an acronym for ICIREPAT (ICIREPAT - International Cooperation in Information Retrieval among Examining Patent Offices) Numbers for the Identification of Data). Because these numbers are consistent in every country, they allow you to read important information from a patent even if you don't understand the language it's printed in.

The INID numbers can be found in brackets after field titles on our database extracts and on the On Line Journal search screen.

The following are the INID numbers used:

  • (11) Patent/Design Number.
  • (21) Patent/Design Application Number.
  • (22) Date of filing of application (if a provisional specification has been filed, its filing date is given; otherwise the date is the date accorded the complete specification).
  • (23) Date accorded complete specification after provisional (if applicable).
  • (31) Number(s) assigned to priority application(s) by the priority country (countries).
  • (32) Date(s) of filing of priority application(s) in the priority country (countries).
