New Format Adopted for Taiwanese Granted Patent Numbers in CAS Databases and INPADOC

28. April 2014

In CA/CAplus, CASREACT and MARPAT, Taiwanese granted patents (kind code B) issued on or after August 1, 2004, and with a patent number of 220001 or higher, now include the letter I (for Invention) before the patent number.

Example:

TW I220001

In INPADOCDB and INPAFAMDB the format of Taiwanese publication numbers for granted patents (kind code B) and utility models (kind code U) published on or after August 1, 2004 will change with the upcoming update 2014/16. The affected numbers will then include a letter before the patent number, which is I for granted patents and M for utility models.

Examples:

PI     TW I424801       B 20140121
PI     TW M471126U       U 20140121

The patent numbers now match the ones published on the front page of patent documents by the Taiwan Intellectual Property Office (TIPO). The new format for Taiwanese Granted Patent Numbers will also avoid ambiguous patent numbers.

The Derwent World Patents Index will also be adopting the updated Taiwanese granted patent number format in the near future.

Customers whose current awareness alert strategies (SDIs) or saved queries include Taiwanese patent numbers should update them to ensure continued retrieval.
